Then are some other skin care acids that may be on the request. These acids may not be as popular, so they may be harder to find in common skin care lines and products, but there’s still substantiation that they work:
| Acids | Benefits |
| lactic, citric, malic, and tartaric acids | AHAs that act as exfoliants, they also work to lighten uneven pigmentation and smooth out skin texture. Lactic acid is the best researched AHA after glycolic acid, and is notable for being gentler, more hydrating, and more effectiveTrusted Source at treating sun damaged skin. |
| ferulic acid | antioxidant ingredient that’s most commonly used in conjunction with vitamins C and E in serums. This powerful antioxidant trio is well known for its ability to protect the skin from the damaging free radicals generated by UV radiation. |
| lipoic acid | antioxidant ingredient with anti-aging benefits. Its effects are quite modest so its popularity is waning. |
| trichloroacetic acid (TCA) | used in peels, and is especially useful for flattening out scars in the TCA cross techniqueTrusted Source. It’s very potent and should be used by professionals only. |
| alguronic acid | byproduct of biodiesel production. It’s reported to have anti-aging effects, but these are yet to be supported by peer-reviewed research. |
Linoleic acid and oleic acid, the assistants to transporting benefits
.When talking about linoleic acid and oleic acid in skin care, it’s substantially in the realm of canvases, where they are n’t true acids per se. In canvases, these adipose acids have replied to lose their acid groups, to form triglycerides. Generally, canvases that contain further linoleic acid have drier textures that suit unctuous skin, while canvases that contain further oleic acid feel richer and work better for dry skin.
Linoleic acid on its own has saturation-lightening parcels, but since it’s formerly planted in canvases, you ’ll need to use a product that’s free of linoleic acid to achieve the same effect. Oleic acid on its own is a hedge disruptor that’s useful for helping medicines access the skin.
Which acid should I use?
Choosing which acid to use is the hard part. The easiest way to go about it is by knowing what problem you want to treat.
| Best for… | Acid |
| acne-prone skin | azaleic acid, salicylic acid, glycolic acid, lactic acid, mandelic acid |
| mature skin | glycolic acid, lactic acid, ascorbic acid, ferulic acid |
| fading pigmentation | kojic acid, azelaic acid, glycolic acid, lactic acid, linoleic acid, ascorbic acid, ferulic acid |
Pro-tip: The more attention, the more likely the acid will irritate the skin. Always patch tests and start with a lower attention before moving up.
Numerous acids offer multiple benefits and since they can come in numerous different phrasings it’s possible to use further than one. Brands will frequently announce the active acids in cleaners, serums, colors, and more, but check the component list to make sure the acid is the active component — listed near the top, and not a forgotten side character at the very end of the list.
