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)...
Citric acid is actually acidic, not alkaline.
alkaline
Alkaline
Alkalinity is a measure of how well a solution neutralizes an acid compared to a carbonate or bicarbonate. A used alkaline battery is most likely very weak, so it wont burn your skin, just wash it off. If a new alkaline battery explodes or leaks onto your skin and it burns you, you should neutralize it with a acid such as vinegar. Then rinse the affected area and cover it.
Alkaline
No, an acid is an acid and an alkaline is alkaline. They are essentially opposites and will react with one another. The product depends on the specific reactants
acid
Everyone's skin is slightly acidic with a pH of about 5.5. This is a weak acid. Most soaps are Alkaline, with a pH of about 9-10. (round about 9.5). Some people find that using soap can dry out their skin. Nowadays, some manufacturers have developed alternatives with the pH of our skin. (5.5). But, most shower gels and shampoos are slightly acidic, and may not all match up with the pH of our skin. Again, with haircare products, they are also slightly acidic.
alkaline because in NaOH, Na is plus and OH is minus. when hydrogen is plus it is an acid when it is negative it is a base (alkaline)

Alkaline
acid PH closes the hair cuticles and alkaline PH opens it shampoo is more alkaline and conditioner is more acidic
