Glycolic vs Lactic

Hi everyone. I recently took an anti-aging class and we were talking about the best acids for aging skin.  The instructor told us lactic is the best, because it hydrates, brightens and increases collagen.  She also said glycolic is not good for aging as it's not hydrating, the small molecules cause it to penetrate too quickly, which can stimulate the inflammatory response, in turn increasing the aging process.  Since so many product lines use glycolic in cleansers and peels, I wanted to get other estheticians' thoughts on this.  (The class was at IDI, not a Dermalogica specific course, but I'm sure they still teach to what they use, and Dermalogica uses lactic over glycolic).  Hence why I want some other 'neutral' opinions on this.  Thanks!

  • i learned this too, and feel the same.  lactic just takes more time, about double the time, too see the results glycolic.  i learned that lactic is bedt suited for dry, sensitive skin types.  however glycolic is effective for ageing, but ehen over used it works aganist your skin by thining it.   moderatiom...  its unfortunate so many products use glycolic.  when used properly under the care of a specialist, results can be amazing.  i mostly lean towards lactic, alphabeta, and mabdelic peel.  i adore jessners as well.  and have had nice results layering. e.g. sal and lactic.  my favorite combo is circadia raspberry enzyme then mandelclear ,  3 lsyers, and thee layers of the vit a accelerator...  wow, my skin never looked better.  but prep before such intense peeling is necessary

Thanks.  What about in cleansers?  I currently use a cleanser with 5% lactic, but I know alot of lines sell glycolic cleansers in their anti-aging lines.

i use circadia amandala milky cleasner, once a day, in morning. i recently discovered both tuel calm down oil cleanser and skin script pomagranet cleansrr.  i usevthese at night.  i used    circadia  vit veil for years, and loved it, but as my skin corrected it became too heavy.  i now use it for post peel cleansing

i really like the skin script glycolic cleanser, but its very strong.  once every one to two weeks is all i am able to use it.  i knkw u like circadia, id suggest getting the milky cleanser.  it really made a difference for me.  very hydrating, and keeps skin exfolkated.  my skin is very reactive due to hormonal factors, so its a tight rope

Right now I'm using Dermalogica Skin Resurfacing cleanser.  I've used Circadia's Lipid Replacement cleanser, haven't tried their new one yet, gotta finish this giant bottle first.  I tried Skin Script's Glycolic cleanser, found it very drying.  I personally think 17% for a retail cleanser it way too high.

the lipid cleanser is best suited for pre treatment to remove oils before peels and enzymes.  i find it is nkt a goood daily cleasnser, even though the pk classes say its a go to cleanser...  i asked dr pugliese about this and he agreed.  u definatly gotta try the milky cleanser....  its off the hook for a lack of better terms.  its launch superceeded the honey cleanser sales.  which is their bsst selling product

the bees wax sucks oils from skin.  dry skin types shoildnt use it more the once a week as a mechinical exfoliant,  great when used with sal cleanser for acneic skin...

I need to get to one of their product knowledge classes.  It's been 2 years and they have so many new products.  Right now I'm using their vitamin C serum and Night Repair Plus.

Cool, thanks.  If we start using the products where I work, I'm sure I'll go to a class soon.  She isn't sure what other product line she's gonna bring in yet.   I'm keeping my fingers crossed for Circadia.
