saliylic acid versus aha's

[NickJeter]

does 1-2 % saliylic acid rejunvenate the skin equally to 8% aha's?

i read aha's work from bottom then up on the epidermis for peeling.

does s.a. do that?

do they equally at these percents stimualte collagen, gag's, basal skin cell growth, etc. for youunging looking skin?

You can read about BHA/AHA on this site.
From my research BHA vs. AHA choice depends on your target.
For acne - BHA is better as it penetrates deeper,
for wrinkles AHA is better as it ex foliates better.
Hope it helps :D
