Sodium, calcium, and potassium hydroxide.Human studies on systemic absorption of thioglycolic acid have not been conducted Sunscreens (oxybenzone, octocrylene, octisalate)īelow the limit of detection up to 8.7% 10, 11Įstimated at 0.5% systemically available 12 Up to 27% is absorbed into the skin, dependent on pH, concentration, and time 8ģ5%–45.3% is systemically absorbed through the skin 9
Levels might be higher when applied to damaged skin 7 Undetectable from up to 25% in normal skin (depends on vehicle, pH, strength, and quantity applied). Small amounts of the metabolite benzoate are absorbed and easily eliminated 2, 3Įndogenous vitamin A levels remained unchanged after repeated applications of 0.05% tretinoin 4
