I am curious about the controversy surrounding the use of epidermal growth factors, AHA, or copper peptides concerning the Hayflick Limit. I understand that cell division can only happen about 50 times before cells reach a state of senescence. Some people say that since exfoliants like AHA, glycolic acid, chemical peels and the like affect only the stratum corneum, the Hayflick Limit is not a concern. However, AHAs are proven to stimulate collagen production while epidermal growth factors supposedly incite cell proliferation. Are these products essentially speeding up aging by encouraging rapid cell regeneration?
