Make Up Artists Choice has two new products that have mandelic acid in them. I was interested in purchasing them and remembered it was on the not recommended list. Under the product detail, it says that mandelic acid is derived from bitter almonds. I was just wondering if you would check these products out and tell me your opinion.

Pore Minimizer With Sepicontrol A5

Thank You

Dr Pickart,
I just found this old thread about Mandelic Acid and wondered if this is the same 'acid' as that sold by Platinum Skincare ? they have a Mandelic Peel that I have just started using?

Thanks !
Caelum

Dear caelum:

Yes, this is the same acid: Mandelic Acid (it is carried in many cosmetic stores/spas).

Dr. Pickart believes their are better hydroxy acids that are gentler (and just as effective) that can be easily substituted.

Best Wishes,

Ohhh
I just started using their Madelic Peel.

I do have Dr Pickart's Exfol, etc.. and was just looking at their peels as i remembered Dr Pickart recommended them at some point.
Unless I"m wrong?

Can you recommend other hydroxy acids that are just as effective that he has or others?

Thank you!
Caelum

Dear caelum:

We have recommended that company before to those searching for effective at-home peels. But we've always recommended either their lactic, glycolic, or salicylic acids. Those are the types that you will generally want to look for.

Lactic acid is one of the safest skin exfoliating hydroxy acids. It is naturally present in human skin and so is very safe in contrast to many unnatural hydroxy acids sold for use in skin care.

Lactic acid is an AHA (alpha hydroxy acid) the synthetic base of which comes from milk. It usually takes about eight weeks of regular use to see a significant improvement in the skin, but even at peel percentages of 40%, clients find that it is effective without being excessively irritating.

Many clients find using a 40% lactic acid once a month (or every 2 weeks) is an effective way to reach certain skin care goals (such as fading marks, blemishes, nasolabial lines, sun damage, etc) --- The days they do not apply their peels, you can use a light amount of LacSal Cream (10% leave-on, mild exfoliant) for everyday rejuvenation.

Best Wishes,
-Skin Biology

Thank you SkinBiology,
I guess it's best I forget the Mandelic peel I have here, Would it be safe enough to finish the bottle? Or start with a Lactic Acid one at 40%?
Why doesn't Dr Pickart have those higher % peels? It would be nice to just get it from him (I wouldn't have made this mistake!)
I'm still working on sun damage and just trying to keep up with my aging skin at 46..I seem to have a heavier skin with larger pores, and lines that just really want to spread especially around my eyes. Deep heavy wrinkling is just waiting to spread it seems. Almost seems like a losing battle no matter what I do.If not for my eyes, I would be okay with the rest of my face.
Any suggestions or is it just inevitable?
Thank you,
Caelum

I would not use a neurotoxin like mandelic acid.

Hmm okay off it goes to the garbage dump then.

Thank you!
Caelum

The right choice!

always appreciate your research!
