Isn't citric acid also In the family of Alpha Hydroxy Acids????? along with Lactic Acid, Glycolic and Malic Acid,Ammonium Glycolate,Alpha-Hydroxycaprylic Acid,mixed fruit acid,etc.etc. I don't encourage people with sensitive skin to use these as I'm not so sure that these may cause UV Exposure .Which in time may damage the skin???Anyone on anti-depressants, or with skin disorders such as ro-sa-sha..Should stay clear of these and other citrus oils in products.Just my opinion....I have witnessed first hand what photo sensititive drugs can do.Skin cancer is not pretty.....Find out all you can about items before you place them in your products.Kind regards,linda
