What are Polyhydroxy Acids? The role of PHA in skincare | Ask Doctor Anne

[@DoctorAnne]

Do you have any PHA products you can recommend?

[@DoctorAnne]

@@sydneyjames2705 You can recommend me to whom?

[@kangaoo2023]

NeoStrataBio-Hydrating Cream - PHA 15

[@DoctorAnne]

@@kangaoo2023 NeoStrata is a brand I have yet to try.

[@internationallanguageofdan3559]

Facetheory Polypep serum has gluconolactone, peptides and centella

[@DoctorAnne]

@@internationallanguageofdan3559 I haven't tried anything from Facetheory yet.

I was using a PHA and didn't know it - La Roche-Posay's Cicoplast Balm. Really like it as my night cream for my really dry skin :) Thanks for sharing.

[@DoctorAnne]

I wouldn't have thought that one had PHA - they are more common than one might think!

[@auricia201]

What? cicaplast has pha's 😯? I've been using it as well, for sensitised or dry patches. Very interesting!

[@DoctorAnne]

@@auricia201 I don't know in which concentration t is used, that plays a huge role as well, but PHA are supposed very gentle.

[@AmritaChougule]

Loved the video. Please do one on LHA as well

[@DoctorAnne]

Put it on my list!

[@sallyadly9826]

love your content Dr. Anne. what are your thoughts about layering Pha or any acids and peptides. i remember reading somewhere they can affect eachother (something about one making the other hydroginated) and i have no idea what that means.. thanks 🙏

[@DoctorAnne]

One works best in an alkaline environment, and the other in an acidic one, which is the reason why they might work better when not layered. The only time where I personally pay attention to not using them in the same routine though is with copper peptides.

I’m using LRP cicaplast Baume on my delicate eczema skin already and enjoy very much, once or twice a week I use The ordinary 10% mandelic acid but once that’s finished I plan on using inkey list PHA toner. Also waiting in my stash to be opened is the skincity luminous licorice toner with PHA 50ml travel size because I’ve not tried it before but looking foward to it …have a good evening DR Anne😊

[@DoctorAnne]

I have a Mandelic Acid Toner from Wishtrend that I need to get out and finally try.

[@moose8762]

There are PHAs in my clay mask; I mostly assume their inclusion is a gimmick. I am mainly a fan of glycolic acid, to be honest. I think it is definitely the most difficult exfoliating ingredient to use in terms of irritation but learning to tolerate it is worth it for me

[@DoctorAnne]

I agree, it is the most rewarding in terms of results for sure. But wow did I go overboard with it when I first started using it!

[@moose8762]

@@DoctorAnne honestly, it is surprisingly strong and I don’t think many people appreciate that. I know multiple people who just say they can’t use it but I think it should be treated more like a retinoid: start with a low percentage and cautiously. Because it is definitely the acid that gives the fastest and most noticeable results

[@DoctorAnne]

@@moose8762 We have a lot of high percentage ones on the market with confusing instructions, like The Ordinary Peeling Solution. I can imagine if that is the first one you try and you don't use it with caution, you come to the conclusion that it isn't for you.

[@babygoatsmum4122]

Interesting. I'm using AlphaH Liquid Gold with Glycolic once a week. I'll look into PHA when I've finished the bottle. Hi from Australia

[@DoctorAnne]

Liquid Gold was my first "real" exfoliant - it is strong, but made such a difference on my skin!

[@babygoatsmum4122]

@@DoctorAnne It is strong but so good. I'm still using Tretinoin nightly as well and am pretty happy with my skin. With summer coming up I'm looking to get a thicker day moisturizer to use for the hot, dry weather.

[@DoctorAnne]

@@babygoatsmum4122 Sounds great.

[@angel-sophiellewellyn9628]

Great video!

[@DoctorAnne]

Thank you. Do you have product recommendations with PHA?

[@mechkitten]

Aveeno came out with a PHA exfoliating cream. I wanted to try it, but it was sold out in my store.

[@DoctorAnne]

That sounds interesting, I will look out for it.

[@auricia201]

I have the Inkey List PHA Toner, but I didn't use it that much, and in the meantime I introduced retinol, so now I'm not sure if I should "mix" them both 🤔

[@DoctorAnne]

I use the toner in the mornings and Tretinoin at night. Just start slowly and see what your skin can take

[@susanmcf1]

I'm interested in The Ordinary 10% Lactic Acid.

[@DoctorAnne]

Have you tried Lactic Acid before? I used Good Genes by Sunday Riley for a long time and really liked the gentle exfoliation it gave me.

[@susanmcf1]

@@DoctorAnne I’ve not tried it cosmetically. It works well in Amlactin for keratosis pilaris.

[@DoctorAnne]

@@susanmcf1 It is a great one for Keratosis Pilaris indeed.

[@mehrinjahan_sadia]

What percentage is effective?

[@DoctorAnne]

That isn't entirely clear, as I mentioned in the video. But up to 10% are usually tolerated well.

[@m.younis9849]

Off topic question please Dr. Anne.. Benzoyl peroxide wash.. What shouldn't i use after it? -as I've heared it cancels many stuff afterwards - TIA 🌹

[@DoctorAnne]

Benzoylperoxide is an oxidant, so it isn't ideal paired with antioxidants like Vitamin C. It can also be pretty irritant, but as it is the wash you are talking about, I wouldn't be too cautious, as it gets washed off.

[@m.younis9849]

@@DoctorAnne OK.. Such a relief! Because I really love the idea of incorporation it a wash off.. Then follow up by niacinamide and Salycilic acid as leave on! Thanks Dr. Anne I have a cosrx product that has PHA alongside centella

[@DoctorAnne]

@@m.younis9849 How is it called?

[@jeffthompson549]

u forgot the best of the best, Clinique turnaround serum

[@DoctorAnne]

Oh, I haven't tried that one. Now I am curious!
