Dr. V, can you make a video about what is the best laser treatment or treatment for acanthosis nigracans on the neck and body? I have gotten my pcos/diabetes under control and have lost weight but it is still very prevalent.

[@gailserran2731]

Please do a review on JAPAN'S TOP SUNSCREENS- Biore, Anessa Milk for Sentive skin. And their POPULAR Club Suppin Powder.

[@juliamambengo]

It's been 2 and half years I'm following your channel. and WOOO! at 37 my skin never looked so flawless and smooth. I finally feel in Control. The POC community owes you so much!! Thanks a lot

[@vanitarattan]

❤❤❤

[@NotEasyButSimple]

Same here. didn't think it was possible to have small pores, but I now do at 37, the best face i've had in a long time. Best part, i'm more conformable going out and about without makeup. LOL

[@monabee2812]

Me, too. I've been following Dr. V. since she started her YT channel (when there were about 2,000 subscribers). And, I've been religiously following her skin care recommendations and using her products. My skin has never looked and felt better. Thanks loads, Dr. V. ❤️🙌🏽👏🏾👍🏾❤️

[@candicescott8214]

Yes! Anytime someone asks me about my skincare routine, I point them to Dr. V!

[@selaphim9941]

For someone with small budget what are the must haves from her range ?

[@sadiayasmin2174]

Am routine: Cleanser Toner Moisturizer Spf Pm routine : Oil cleanser Cleanser Toner Serum / exfoliation 2x a week Moisturizer

[@anandikabanduni8419]

It’s taken me 3 years to control my acne and my skin now is very slowly evening out. Skin care and wanting to achieve glass skin has taught me that your skin doesn’t fix itself overnight and an immense amount of patience

[@vanitarattan]

❤❤❤

[@shr3970]

Dr V can you please make a complete underarm routine for SOC targeting people who have all these three things at once which are 1. excessive sweating and odour 2. hyperpigmentation and spots 3. excessive hair growth

[@wendyn3256]

Skin of colour here and love, love, Korean skincare.

[@TeashaG]

Same

[@carolynbland8910]

I’m 64 years old and have benefit so much from Dr. V skincare my skin never felt so much better ❤

[@vanitarattan]

I'm so glad!!

[@carolynbland8910]

Hi Dr.V my name is Carolyn ,I am a loyal fan of yours. I’ve been using your product now for a year and this is the best my 63 year old skin has ever looked. I always look forward to watching all your videos and I was even was able to help my grandson and he continue to thank me for helping him along the way . Before using your products I was all over the place using various skin care products that was making my skin worse .I just really appreciate having you into my life helping me along this journey with my skin care. I definitely see the different thank you and God bless.❤️

[@katlegomhlauli8423]

When I turned 30 my skin just decided to do its own thing and thanks to you now it’s thriving

[@mzjayalwayz]

I had the worst… mean absolute worst hormonal acne. I mean I didn’t want to leave my house. Because of your channel, I’ve been watching since 2020 and I’ve been able to heal a good amount of it. I still have a ways to go but I definitely feel my confidence returning

[@vanitarattan]

I'm so glad! Xx

[@studentdrfit]

I know you have to promote your products. But it would be nice to also add in other NAFE safe products that may do similar things as well for all the items you’ve listed. Especially for those that mainly get products in person in the US from a Target at least or Sephora at most.

[@Peace4Love4Smile]

if you look up her shorts and past videos, she did suggest products that are nafe safe and even budget friendly. That's how I started out!

[@canesugar911]

Majority of her content are recommendations for other cheap brands

[@April50-n1v]

I recently bought round lab cleanser the oil one and the foaming cleanser they are great for sensitive skin

[@AGNYC]

you should do your research before you suggest. she's recommended tons of other products, not just her own.

[@collegeopera]

Remind one again what NAFE stands for please?

[@shr3970]

Dr V, can you please make a video covering nails safety for SOC overall including nail polish, gel, acrylics, use of LED lamps, UV lamps, feet nails, etc.?

[@Jmwamuchemi]

Yes that would be highly appreciated if she does that

[@thivipavan1329]

Yes! That would be great!

[@FynazDramaQueen]

First I want to say as a woman of color thank you for this. I love watching your videos. You were in my head with this one.

[@kdmorrison7536]

I use the range, and started just over a year ago. I am getting compliments on my skin. I have never had this many compliments on my skin before. I am in my mid 40s. I can't live without t]the Dr. V range. The best products!!!!!!!

[@vanitarattan]

I love it!!

[@mauryne1391]

Dr V my only skin doctor. I dont buy a product that is not recommended by her. I am buying her products because i am tired tired tired. My skin is dry and acne prone. Shes my answer

[@MyztiRose]

Been using your products over a year now and my skin does so much better with your products. I also love how they feel on my skin compared to others I've tried. And plus the fact that they work so well and are all fragrance free. The sunscreen stays on for hours, it's like glue. I did use Paula's choice but after I ran out I started to use your sunscreen again and realized just how much more my dark spots are fading. I'm addicted!

[@Angie-iq1xq]

Yay ! I've managed to actually see a video within the hour of posting. Love your skincare. Since using your brand I have had lots of positive comments about my skin. I go between your brand and when it runs out I use 'The Ordinary' while I save for the next delivery of Dr V. Thank you for the gift of great skin. ❤

[@vanitarattan]

Yay! Thank you!

[@tary5024]

My face has never looked so good since l started using your products recommendation. I have dry acne prone skin and wow l am so confident now

[@Zerael071]

What do you use? I have dry acne sensitive skin and I’m having problems finding a good regimen that works for me.

[@SSL-1912]

Hi Dr V. Thank you for these beautiful products tailored for the skin of colour community. They are both appealing and necessary in today’s market. However, I wanted to bring to your attention that the pricing for your products outside of the UK may be a barrier for many potential customers. I kindly encourage you to consider exploring options for lowering prices or implementing regular promotions. This could make your wonderful products more accessible to a wider audience. Thank you!

[@fatimasheikh560]

Thank you so much for all the effort you have put in for our SOC family!! ♥️ I have been using the entire Daily Range for quite some time now and I am on my way to achieving that glass skin (skin tone is more even and skin texture has gotten soooo smooth) 😍 only thing I wish for is a lip spf for the day made by you 😍♥️

[@vanitarattan]

Thanks for sharing!!

[@sushxelestine]

Exfoliate to glow is one of the best skincare product i ever purchased. I wonder why its not viral in mainstream media

[@anna-staceiablackwood8653]

I’m currently using all the products except the SPF. I absolutely love them all but the moisturizer is my absolute favorite my skin feels so supple and hydrated. My problem is I can’t sleep on my back for the entire night

[@WinstonLorde]

I always have to watch her videos twice. The first time I am so mesmerized by her mellifluous English accent and her alluring face that, unfortunately, I miss some of the knowledge she is conveying.

[@trinichandy3049]

Thanks for sharing your knowledge on skincare. God bless.

[@studentdrfit]

⁠what I more so meant was within the videos where she has a topic and lists ingredients and then her product, it wouldn’t hurt to also list alternatives as opposed to having to scrub through past videos. But since you all are experts, maybe you could drop products she’s listed in the past?

[@Peace_4424]

Love your products❤ not just lovely results but no need to waste your time or money on other millions of products. It just made my life so easy.. running low, order more

[@winnifredcjames7556]

I would love for Dr. V to make a product that will slow down facial hair growth especially the chin area. Thank you

[@NurseBrell]

Anytime people ask me what do for my skin? I refer them to your channel and I never buy anything unless my doctor says it’s OK😊 Thank you Dr. V

[@simisur9404]

Iv been following your channel for the past 2 years and my skin has improved a lot .. many many thanks to you doctor.❤

[@vanitarattan]

🙏🏽🤎

[@DeeL-u1c]

I have been using the everyday skincare set since Dr V launched. My pores looked cleared out. I don't break out as much which was rare anyway cause that's how post menopause works on me. I may try other skincare, but at night, I reach for her toner, power serum and pep moisturizer. I will try the oil method now that she mentioned it.

[@AlitaMee]

0:12 finally Dr. v thanks for sharing this. We are different than korean skin. I realized this when in gym Chinese and korean gals were not smelling while we indians were smelling like crazy , i was using benzoyl peroxide so i was okay. But then one gal said to other thank goodness we dont smell, i did a little research and found they have a gene which doesn't make their sweat smell. So that means our facial skin is different too . They have very less hair . Korean and Chinese men has less hair on their legs than i have on my arms . Yeah we are different.

[@connie4008]

Your channel and expertise are the best! TY for educating us and saving our precious skin of color 🥰

[@Capius1272]

I absolutely swear by the Inzincable. Sometimes, I would apply it directly in a rush (because it does hydrate and has a glow) and learned that's a no-no for my skin. Skin texture was affected. Use it properly with a moisturizer under and may apply it twice (albeit much more than a "drop") max per day (early stages of Vitiligo with minimum reddening of the spots when this is on) because the glow stays even beyond the recommended reapply time. Good product. I buy the max 6 every time! Still trying things in your line but was reluctant as some of the other items didn't agree with my heavily textured combination Vitiligo effected skin well enough. Yet some of your past recommendations on other products/brands have. However, I want to support what you have helped me accomplish via purchasing yours. Otherwise Ill stay there. But Inzincable? Is untouchable. A staple in the cabinet. The Cera Pep and retinaldehyde serum are next.

[@creativequeen8371]

Thanks for sharing that information.

[@KariIllustrations]

Hi Dr V! Can you do a video on what products to use for post chicken pox scars please! Mainly dented scars on the face, for adults who got chicken pox late in life! Thank you!

[@vanitarattan]

Yes ❤

[@rifsad1238]

I’m 46 and everyone says I look 30. I’ve been using these product the day they came out. I’m in the sun all day everyday. I get pigmentation. But with the sunblock, I no longer get it. My skin is flawless

[@creativequeen8371]

Nice 👌🏾

[@Botdabot]

Dr V you should go over the best products for Combination skin as a Teenager myself I don’t know which products work the best and dosent destroy my skin.

[@alkashandilya4497]

Dr V I have learnt a lot about Skincare with you and finally have figured about best for my skin. Thanks you…

[@karynjacksonhuggins9457]

I enjoy your channel and wish your products were in Sephora or Ulta because they don’t travel well from the UK to the US. Customs always open the package, opens the products and don’t seal them back properly. By the way, the pictures on this video were all of young white girls, it would be nice to have seen some WOC.

[@paularand8783]

One of the reasons I don’t watch her as much

[@L20241]

Please get your products in Ulta or Sephora for those of us in the US

[@alecbarney3298]

She’s talking about Korean skin which are light skinned…

[@vanessas.8234]

She always showcases women of color..... This video was specifically about Korean skincare...... Hence the lighter skinned Koreans in the video......

[@karynjacksonhuggins9457]

The title of the video is Glass Skin for Skin of Color. Perhaps a little misleading.

[@joesham5075]

Thank you for all the information but can we only achieve glass skin by using your products only please advice thanks again 😊

[@khushbookalia4116]

I have tried almost everything available for my facial pigmentation and nothing worked for me, have been following your channel for a few years now and ordered the DrV Facial pigmentation kit in 2023 which of course cost a fortune. Was highly disappointed, tried it the first time, caused purging and reactions, stopped and tried again with the same results, further tried to use it less often by decreasing the frequency but the same purging and reactions on face. Finally gave up and the kit is lying as such in my cupboard. With the kind of claims Dr V had made for her products, the kit did not even fulfill 1% of it. I still believe in Dr V’s knowledge and the way she explains everything but too sad that her own brand could not support her claims and knowledge, what hurts most is that I belong to the skin of color family, and still was let down by a skin of color expert😢

[@S.Pri8]

Hi. I just wanted to acknowledge your feelings and say to you, I'm Sorry you're dealing with that🥲 I understand very well how you feel. Just keep going God hears us❤

[@Charlotte-ql1ju]

Same experience here. Zero effect on my mums hyperpigmentation and super pricey as well.

[@rozmeenbhaw7656]

I use to watch her videos in past when she was really genuine but now I feel she did all that to launch her products ONLY. Not sponsored but self sponsored

[@lilianotieno8009]

😂😂😂😂she is a business woman looking out for her products we can't fault her. Good thing we have old genuine videos to compare. I am stunned she wants people not to use Korean products like they are way cheaper and much more effective than the products she is promoting. For 1 of her products you can buy like 3 Korean skin care. Now with that kind of pricing for super effective products of K beauty, why would I buy anything else 😊😊😊

[@funmio157]

Hello Dr V. I love your videos and your honest reviews. As feedback, while I appreciate the formulation of inzincable, it does leave a white cast on darker skin tones.

[@vanitarattan]

Oh no! It's the most invisible zinc oxide raw material and formula possible 🙈

[@vanitarattan]

Oh no! It's the most invisible zinc oxide raw material and formula possible 🙈

[@yasmeenkhan5772]

NAFE SAFE actually saved my skin. Thanks doctor V

[@Risee_Revolution]

Does my skin care routine need to include a toner and exfoliant? What do you think about this routine ? At am CeraVe Foaming Facial Cleanser Daily Face Wash, snail mucin, a moisturizer (optional) and sunscreen. At night PanOxyl Acne Foaming Wash Benzoyl Peroxide 10%, snail mucin and moisturizer. Please give me your opinion and suggestions.

[@elaineturner8163]

Hi Dr. V! Hope all continues to be well with you and yours. Question - would you consider selling your products on Amazon here in the States? Thanks so much for this video. 💖

[@vanitarattan]

❤❤

[@twinztjenkins7075]

GREAT QUESTION

[@amenamukta1559]

I have recently purchased your AM PM kit and hyper pigmentation kit together. Could you please make a video on how to combine them for best results?

[@vesbarrow]

[@dragonflyj]

My skin looks sooooo oily trying to achieve the "glass skin" I've learned pretty early that def. is not for skin of color. Thank you for explaining this to us!

[@vanitarattan]

❤❤

[@Valentina02-p8h]

But isn't COSRX a Korean skincare brand. You've recommended COSRX skincare products (snail mucin) before

[@Fuzzy_Slippers111]

That’s just an essence, I doubt it matters the difference in melanocytes for that

[@aakankshagupta7899]

She recommended because its a good product, works as anti ageing products,but it will not help achieve glass skin

[@pixieinx]

I think it’s about if you want to have the glass skin effect, like she said in the video it’s about get the glass skin benefits doesn’t mean it’s a bad product it’s about getting the best results for skin type, skin tone and skin condition etc.

[@afrakoma_a]

I use their sunscreen and BHA and they are great for my skin. If it's working for you, just continue.

[@soniaberry8132]

She said u can't achieve glass skin the Korean way cause they use only hydration and because .......... She doesn't mean it's not gonna help their products only won't help ma'am do u copy?

[@ILove500DaysofSummer]

Can you specifically name vitamin c products you recommend using with retinol

Hello Dr V, I have acne prone skin , Can I wear -The Derma Co. X Dr V Skin Renew Barrier Repair Peptide Moisturizer with Peptide & Vitamin C Because it has vitamin C, will it clog my pores?

[@TrilokyaK]

It gave me acne I bought it lot of expectations

[@melisangina2864]

My issue with products is i struggle to find products that dont trigger fungal acne but also provide enough hydration and keeps the barrier intact. I have oily-combination skin

[@vanitarattan]

Opt for gel moisturisers. I made a video x

[@jamilatouburinyuy8833]

Dr V , i really wish I could get your skin care line for my skin here in Cameroon. Hope you reply. Been following you and I have learnt a whole lot

[@afiyafiza9720]

Doc can u share a diet as well as what we consume basically reflect more

[@pratibhachoudhary7362]

Thanks a lot Dr.V every other youtuber I watch, be it Indian or not every single one of them rave about soonmany Korean skin care products. I have known for a long time that Korean skin is different from ours and it is realistically impossible to achieve that glass skin type of look for us but I do find snail mucin and cosrx birch sap moisturizer and green tea toner very soothing and healing for my skin apart from that one product I do not think any Korean skin product has done much fory skin and I do feel regret getting influenced into buying some of the expensive products that haven't done much for my skin

[@unseen4491]

I really wish to have ur products in Canada directly from the shop other than ordering it online

[@geetakumar4399]

I have been following u for past 2 years u r the best in the industry

[@vanitarattan]

🙏🏽🤎

[@ZairianPrincess]

You can achieve this with Korean Products it's all about the actives and he layering. I'm a formulator and work with Korean brands

[@Sunny-gy9vk]

Dr V please recommend a humidifier - thank you ❤

[@shree415]

But Dr V few korean products are quite mild and have the ingredients you mentioned mostly Centella Asiatica

Lots of love from India❤ While using your lip pigmentation kit, should I wash off the scrub from my lips and then apply the mask and balm? And when should I stop using the kit?

[@rituahirwal22]

How did u purchase that ? I think we can’t buy that ? Will u please explain the procedure ?

[@Cantetinza17]

When I went to South Korea, I purchased skincare products from Duty Free and it really messed up my face! I learned from that day. I don't normally have bad skin, but my poor face was having a fit! You're line is really good. If only you had the pimple stickers that you can wear over night. I'm jazzed for the bigger bottle though. That's some good stuff. I will be purchasing the big bottle soon.

[@trudystone2049]

Dear Dr V. I have mixed heritage skin. More Olive. I suffer from melasma, hyperpigmentation, and dark under-eye circles. I have purchased your beautiful products in the past. I love them. I am now a single Mum, and care for my Mum after she fractured her hip. So 24/7 I care. And no longer have a job as a teacher. The prices are higher in Australia. Our dollar is not doing very well. I do however, use other products that you suggest. So thank you. I did have a question, I still have your glow serum. Do you leave in on all night? Or wash it off after 10 minutes? Thank you 😀 😊 🙏 💓

[@marciaharris8983]

I will be buying that sunscreen asap. Thank you Dr. V. Please make the brush on shield.
