[@dave9401]

Casandra, I would love to see you talk about mineral sunscreen more, things like: the photocatalysis of zinc oxide (ZnO) and titanium dioxide (TiO2). Is the non nano form still a photocatalyst? Do coatings on nano particles work to make the particles photostable or do the coatings go to shit in formulations? What about the different forms of the particles, rutile, anitase etc. What is the uv attenuation of the particles at different sizes? What is the dermal penetration in skin with atypical histologies? And what ingredients should you avoid in a Sunscreen (citrus essential oils and retinyl palmitate come to my mind as they display phototoxicity)? P.S. Love your channel and no nonsense vibes. You call 'em as you see 'em and I really like that. Your info on cosmetic products has more breadth, depth and accuracy than most dermatologists on here btw.

Having sensitive skin, I've always been cautious about trying new skincare products. However, after hearing great things about littleexttera rice berry vit C serum, I decided to give it a shot. I've been using it for about three months now, and I'm extremely pleased with the results. The serum has a gentle formula that hasn't caused any redness on my sensitive skin. It is quickly absorbed and leaves my skin feeling smooth and hydrated. I've noticed improvements in the overall tone and texture of my skin-it looks brighter and more even. I use the serum every morning as part of my skincare routine, and it performs wonderfully under my riceberry sunscreen and makeup. The packaging is straightforward and practical, though I do wish it dispensed a little more product per pump. Despite that small concern, I would recommend this serum to anyone with sensitive skin looking to use Vitamin C in their skin care regimen. It's been a gentle but effective addition to my skincare regimen now.

[@Rahideshmukh619]

This vitamin c serum by litttleextra riceberry is amazing. It performs exceptionally well and has reduced my pigmentation a lot. It has no fragrance. Is a good match for my skin.

I've simplified my skincare routine because I'm starting school soon and I'll be on a tight budget. Currently only sunscreen, double cleanse, retinol and a basic AHA. Might include an esscense and vitamin C once I have a bit more disposable income. Edit - I do use a basic moisturizer on nights I dont use retinol since my retinol is in a moisturizer. I only use sunscreen in the morning. My skin doesnt need more moisture in the morning

[@enakshi8729]

[@meganepelletier853]

@@enakshi8729 My thoughts as well! Especially when using a retinol and AHA. Not moisturizing when using these actives is likely to result in dehydrated skin, more irritation and peeling. If on a tight budget I'd recommend going for a moisturizer before buying an essence or vitamin C. There are definitely a lot of good inexpensive moisturizers out there. I believe Dr Dray recently made a video with moisturizer suggestions under 10 or 7$.

[@raha5527]

@@meganepelletier853 I don't know what products this person uses but for example, I use a retinol that is formulated in an oil form so I don't need to layer anything on top and it won't dry me out. Sunscreen is also sufficiently moisturizing for the morning so I don't and to be honest can't layer a moisturizer underneath. I think I'm in the minority but my skin can only take 2 (one toner/essence or serum and one a bit heavier product like sunscreen or moisturizer/oil) products on top of each other so I have to simplify things and pick multifunctional products.

I am a little worried my skin got "used to it" though, but maybe I was using other products that influenced that.

[@johnayala2540]

I've been using Vit C for about 20 years now so I've tried tons of it in different brands but the best for me (and the cheapest) is the Vit C powder 1/8 teaspoon mixed with 5 ML of my favorite moisturizer (Cetaphil). If you're new, build up your tolerance by starting with 1/16 teaspoon Vit C powder. Using Vit C powder you get new mixture of Vit C everytime and it's important because Vit C is so unstable but the benefits as skin brightening & texture is amazing. At 59, I have zero age spots, zero wrinkles & zero fine lines. I never had botox or facelifts but I had done micro-needling. Note: Vit C could sting when you first started but the stinging can be greatly diminished by applying moisturizer first. The sting will disappear in few minutes..

I use The Ordinary one right now, every other evening, after Mandelic Acid (alternating it with Retinol 0.2 in Squalane). The effect of this has been amazing for brightening my skin overall and for the pigmented spots. And I adore the smell, it smells like freshly squized grapes in the fall, when the wine is made.

I’ve seen no influencers talking about this brand but I literally just came across it last week because I was wondering why so few brands make vitamins C in *airless pump* packaging because of how prone to oxidization it is! *Timeless Vitamin C 20% + 1% E + 1% Ferulic Acid serum* - Looks like a very good but much more affordable replica of SkinCeutical and comes in an AIRLESS PUMP! Which means much slower oxidation!! And its *less than $100 for a massive 4oz* The brand is also super sustainable (all their bottle packaging is recyclable - either ordinarily or thru terracycle - things like airless pump) and *cruelty free* - I think it deserves a Cass-Pass doesn’t it?? It’s also a Californian brand! Why no influencers in this circle never mention anything from this brand? Is it just because they are not sponsoring??

Clicked on this video because of the Dear Klairs serum in the thumbnail - my #1 vitamin c serum recommendation for beginners. I would strongly advise storing in the fridge - no heat anymore though. But in the fridge, it will last a really long time - no oxidation. I would also strongly strongly recommend the Dear Klairs Freshly juiced Vitamin E mask - it really maximizes the vitamin C serum. The only thing is that it's a little heavy for oily skin in the morning but a little can go a long way so I use less than I would normally use and I love to use it at night right after vitamin C - for plump glowy skin the next day.

I have always had dry, sensitive skin with eczema (the eczema has gotten better with age and living in the desert). I would get pimples but mostly around my temple area. Anyway, I started using the patch birth control and I would lay out in the sun, so I developed hyperpigmentation and the more I laid out, the worse it got. I finally stopped when the skin above my upper lip started turning brown 👀. So I needed to find something. Now, this was back about oooohhh saayyy, about 12 years ago…this sales lady at Ulta recommended this product made by L’Oréal. It was a serum that had ascorbid acid as one of the top ingredients and it had this beautiful, pearlescent, shimmery glow to it (nothing crazy but it did make your skin luminous and it was soooo pretty!) Anyway, within a week I began to notice my skins pigmented spots start to disappear. I used it once a day everyday. When I came back about a month later to buy more, they stopped carrying it 😭. Almost as soon as I stopped using it my dark spots returned. I kept my face out of the sun as much as possible and would use foundation with SPF since I hated the greasy and stinging sensation from using straight sunscreen. Anyway, I haven’t been able to find the serum anywhere and if anyone has any suggestions on what to use I’m all ears. I’ve been a fan of Korean beauty for about 3 years and I’ve tried different things here and there as well as Oil of Olay, Neutragena, Garnier, even L’Oréal vitamin C Revitalift and Roc. None of them have worked. I gently wash my face at bedtime and in the morning. Ive been using Sweet Chef oak milk latte cleanser and Sweet Chef Vitamin C bright spot tonic and it’s worked but only a little bit. I’ve tried brightening serum and retinoid cream from Admire My Skin and it didn’t do anything. I exfoliate maybe twice a month and never ever go without Ponds moisturizer every time I wash my face, which I have been using since the 8th grade. I haven’t changed that up because my skin needs that very thick moisturizer to soak in. Ok this is so long and I apologize. TL;DR I need to find something comparable to that L’Oréal vitamin C serum. The current one in the red tube does nothing for my skin. The shimmery serum was the only one that really works for me. Any suggestions please let me know!

There’s no need to use an extra product with vitamin c serum as long as your multi-antioxidant serum has at least 5% L-ascorbic acid and is stabilized. In modern days, *all* of the best vitamin c serums are multiantioxidant serums because antioxidants often work synergistically to enhance each other’s effects.

I have a question about the one you mentioned with dimethicone. I like that feel on my skin, but always wonder whether moisturizers over that can penetrate. I feel as if dimethicone products would be last before foundation (like a primer). Does that matter?

Silicone derivatives such as dimethicone are permeable, therefore, your perspiration can get OUT, and your moisturizer can get IN.

Dear Klairs is indeed amazing. Only concern: it causes dryness. I have oily acne prone skin, still it makes my skin somewhat dry - so go with a good moisturizer. ⚠️ Don't apply it under your eyes, I made this mistake, it made my eyes really dry, heavy and tired looking. I was about to visit a doctor but thankfully I realized it was due to this Vitamin C serum. Then I carefully started applying it avoiding eye area and I am good.

I would love to know what you think of the vitamin c with ferulic and vit e from Timeless. I’m asking because I am currently looking for a vit c and ordered that one because it’s available at target online and some say it’s close to the skincuticals one but a fraction of the price. I paid $21 but it hasn’t arrived yet so I can’t say how well it works but I have heard vit c works best with ferulic acid and vit e. Another youtuber did a video testing the ph of a bunch of different popular vit c’s and many of them weren’t at the correct ph to work but the timeless was at the correct ph. I’m hoping it’s not too good to be true since it’s affordable. I’m hoping you approve :)

In the past i bought Timelesss but i felt it was too strong on my skin( which never happens for a vitamin c and the bottle was leaky), and Maelove- which was good. But, with G&G i feel like my skin liked it the best. ONLY downside is shipping to the US( u need to spend $70 for free shipping or pay for shipping)- but i ordered 4 things from G&G i wanted to try so it worked out! But, its a good quality Vitamin C for sure so i hope they become popular to sell it in US stores one day! My problem with Vitamin C is i never finish more than 1/2 the bottle before it starts going bad so i wanted a cheaper one.

With the hot weather and my habit of touching my face, I've seen pimples starting to form again. So, I decided to give this serum a try. After one night, my skin feels perfect-no need to wash it every 3 hours, my nose isn't glowing from oil, and the pimples are healing. I highly recommend it to anyone with similar issues.

Hi, just wanted to mention it's also important to check for pH level. The pH needs to be low in order for the skin to absorb the vitamin c. That's why the likes of the Inkey list one felt nice and not irritating at all, but didn't improve the look of pigmentation. So there's no point buying it if it's the vitamin c that we need. Some products will say what the pH level is on the packaging. Some don't unfortunately. Thanks for video

I wish you had mentioned Skinceuticals CE Ferulic. I got it on sale and it was good, but I can't afford to repurchase.

Hi Cassandra! This is extremely random- I had a malignant melanoma 3 years ago (I know, yikes.) and was told by my Derm. not to use any products with EGF. The thought process being: EGF speeds up cell growth- including any cancerous cell growth. Have you ever heard anything like that? It's not like EGF is in a lot of products so I've never had a problem avoiding it, but I always wondered if there was really any consensus on skin cancer and using EGF. I just thought of this because of the Inkey List EGF / Vit. C product you mentioned.
