Is the skin care acid or alkaline?

acidic for instance: Alpha-Lipoic Acid (anti-aging, protection against free radicals), L-Ascorbic Acid, Hydroquinone (used to lighten hyperpigmentation), Alpha-hydroxy acids (AHAs, side effect mild irritation and sun sensitivity), Beta-hydroxy acid (salicylic acid),

DMAE (dimethylaminoethanol)(present in salmon and sardines, boosting the production of acetylcholine), Kojic Acid (similar effect as hydroquinone, if you are allergic to hydroquinone you can use Kojic Acid)...
