Hi Michelle, can you do a video on ‘pores’, perhaps their biochemistry, how they work, and common myths surrounding pores on skin, please? Thanks for all the informative content. Keep it up!

[@LogarAcc]

pores don't have a "biochemistry", they're literal holes

[@kbear1275]

Thank you for a wonderful video! Very informative! A couple of years ago I heard a dermatologist talk about the ABC of skincare. “A” for vitamin A or tretinoin, “B” for vitamin B or niacinamide, and “C” for vitamin C. The derm basically the “A” was best and most effective for the skin. I use the first two (A and B) and they work wonderfully. I tried for a few years to use vitamin C and it didn’t do anything for my skin. I made sure I used the ascorbic acid version and tried inexpensive to expensive versions, water based and oil based and didn’t see any change. I’ve seen pretty major changes in my skin with using vitamin A. And vit C can be quite expensive. With the vitamin A my insurance covers it. It’s been well worth it for my skin.

[@LabMuffinBeautyScience]

It's definitely not necessary for everyone, although I do like it because of the potential long term advantages. I would personally pick a proper retinoid over vitamin C!

[@geslinam9703]

Same here. I did a lot of research and chose a pretty pricey Vit C serum, which I used religiously every morning after cleansing, for over 3 months. I saw zero difference in my skin. Been using Retin A for about 5 years now, with excellent results, and figure the other skin care products I use have the antioxidants I need. Won’t be buying any more Vit c serums.

[@Aris-Darling]

I love hearing you speak! Such a calming voice, demeanor, and accent. And most importantly, I love how you share your knowledge and research. Thank you 😊

[@NicePerson58]

I choose retinoid rather than Vitamin C. Retinoid have the best evidence when it comes to reverse sun damage. People love Vitamin C because they can brighten their skin and presumably boost collagen production. But they tend to be on the pricier side. I'm in love with Tretinoin.

[@LabMuffinBeautyScience]

If I had to choose I'd pick tretinoin too! But I use both ^_^

[@Tony_Foster]

I agree with Michelle. Why choose ? Use them both. ^^

[@quillpen815]

Pretty sure you aren't supposed to use any type of retinoid if you're pregnant or planning to get pregnant. Besides, most people use topical vitC specifically to target hyperpigmentation spots, and in some countries tretinoin is prescription-only; lack of accessibility is the biggest reason others turn to other ingredients to do fairly similar effects.

[@NicePerson58]

@@quillpen815 hyperpigmentation can be treated by using other ingredients such as arbutin, kojic acid, licorice root, niacinamide, etc. For women who get pregnant, there are other ingredients that can help for anti aging such as Alpha hydroxy acids. 9 month pregnancy without using Retinoid is okay. After they are giving birth, just use it back.

[@MagicznaPanda]

Following your previous posts on Vitamin C I started using it every morning. First using your DIY recipe (it's great for slowly ramping up the concentration), and then I found a local skincare company that produces their ascorbic acid serums every 2 weeks to make sure it arrives fresh. The formula seems pretty generic with ferulic acid, glycerin, sodium hyaluronate, and panthenol - but it's 15% at

[@LabMuffinBeautyScience]

Yay I'm glad you liked it! That sounds like a really good way to ensure freshness :)

[@_Hello_4444]

Would you mind sharing the local company you purchase from? I would be interested in seeing if they may ship! ☺️

[@MagicznaPanda]

​@@_Hello_4444 Sure the company is BasicLab (based in Poland, as am I), and the serum is called "Serum z witamina C 15%" That being said, the main reason I went with them was because I was concerned how imported vit c serums (for example Paula's Choice, which doesn't have its own store over here) might sit in a cold/hot warehouse for unknown amounts of time - unless I bought it directly from them, in which case I'd know it was a couple days I guess. But with something that perishes relatively quickly, I just didn't want to pay the extra 15 EUR for shipping every 3-4 months. Then again, BasicLab also seem to charge about 15 EUR for shipping across Europe (except Norway and Great Britain), so I feel like you're not much better off ordering from them.

Stir it until its mixed and has a serum feel to it, and apply it all over my body. It's inexpensive, super fresh and only adds a few minutes to my after bath routine.🌱

Using a salicylic acid face wash in the morning before applying vitamin C aids in penetration. Even better, use an acidic toner (I use an AHA/BHA/PHA toner) to further increase penetration. Otherwise, apply it before anything else.

[@elettramia6380]

I got really enjoy the timeless brand of vitamin c. I got the 20% and next time I’m going for the 10% because the 20% is too harsh for my sensitive skin, plus I use retinoids so it’s even more sensitive. I watch a dermatologist that preaches stronger does Not automatically make the product more effective. How do you feel about this? Also the theory which I find to be true for myself is if you are using a stronger percentage, you are more likely to get irritation which results in you actually using the product less making it less effective. Lower concentration means less irritation and therefore you can use it more often and reap the benefits.

5:25 "you have to be really careful otherwise you'll burn your face off" I wish I watched this video before my endevour with vitamin C in the morning and retinol at night. I've been slowly easing my skin into retinol with a low % but I went too confidently into vitamin C at 15% daily for about a week and a half until my skin got stingy and the next morning my skin was dry and tight and even stung with some antiseptic ointment creams but I continued use as I knew they were safe for face and on broken skin and then I moved onto nivea cream in a few days (german version) on top of a thinner moisturiser which has helped soothe the dryness and help the flakes sort of melt off instead of flaking and my skin is finally almost done shedding like a snake a week after I noticed stinging and stopped with the vitamin C and retinol combo. I will ease my skin into it much more gradually now and maybe not use a 15% vitamin C daily, I might find a derivative to use for in between days

I use the alpha arbutin + Tranexamic acid serum first and follow them up with the vit c + ferulic acid serum after, then moisturiser, then sunscreen everyday.

[@thisxgreatxdecay]

I am a bit confused about if Vitamin C and retinoids can be layered. Conventional wisdom is that L-ascorbic acid and retinol shouldn't be layered, because they destabilize each other and work at different PHs, making each other less effective. I do sometimes read that more stable derivates can be layered (like retinyl palmitate or granactive retinoid and magnesium ascorbyl phosphate or sodium ascorbyl), but that one would not be able to layer, say, tretinoin and L-ascorbic acid. I've seen some folks say you CAN layer them, so long as your skin can tolerate them. I've even seen some say that, contrary to popular belief, they don't destabilize each other, but actually stabilize each other. Is this true? I see one study that these folks mostly cite. I've only read thr abstract (I don't think I have enough technical understanding to bother trying to read the actual study), but it seems to be that it was a split-face study that compared a retinol/vitamin C mixture to a placebo, rather than a retinol/vitamin C layering to people using one or the other. Does the fact that the experimental group saw better results than the control group show that these products don't destabilize each other? Or does it only show that, even if the effectiveness of the products are reduced when combined, they still produce SOME results, and certainly better results than just applying a vehicle? pubmed.ncbi.nlm.nih.gov/15767769/ My second question is about layering AHAs or BHAs with L-ascorbic acid. Most websites say this is a no-no, too. But they mostly say it's a no-no because of irritation. How about for the people whose skin can tolerate it, though? Do the products destabilize each other/reduce each other's effectiveness, or are they fine layered?

@@LabMuffinBeautyScience Hi Michelle I have a query. You have said that the spf differs with the quantity we apply. Does it applies to uva to? For instance overapplying a pa+++ sunscreen can give protection equal to pa++++?

[@LabMuffinBeautyScience]

@@linalex3860 Maybe, but it's really difficult to overapply enough - PA+++ to PA++++ is double the protection, you'd need double the normal amount of sunscreen.

@@LabMuffinBeautyScience Thanks Michelle, here in India pa ++++ sunscreen are pretty heavy. So I apply more and frequently of spf 30 and pa+++(they are very light). I think you might like Indian sunscreens, they mostly use tinosorbs and uvinals for uva and they are very affordable tho.

Is there a part 2?

[@SAYoung15]

I have the tatcha vitamin c and it’s decent but I can’t wait to try some of these

[@learnandearn7584]

I will be making formulation for hyperpigmentation where i will be using, rice, tomato 🍅 and potato as active ingredient. Using microspheres technology. The dosage form will be in aerosol, stick. Mainly waterless stick. How does it sound. It's my project work. Please tell. 🙏

Can anyone share the link for part 2 can’t find it

[@terrythedad7240]

Sorry if I missed it but how does liposomal c fit in there? Not sure if it’s in any skincare products already but wondering if it would be any different than what you’ve mentioned.
