Best Facial Acids for Common Skin Problems ...

Aging causes skin to become thinner and drier as a natural result of oxidation and collagen loss. The goal is to find facial acids that combat these two processes, as well as minimize dryness. Ferulic acid, alpha lipoic acid, and ascorbic acid are all antioxidants that can minimize wrinkles. Alpha lipoic acid can also be bought in pill form to take orally to enhance the effects of topical application. While ferulic and lipoic acid can be used by all skin types, ascorbic acid is best suited to dry skin. Collagen stimulators, including retinoic and glycolic acids, are absorbed into the deeper layers of skin where collagen production occurs. Due to their greater absorption rates, they are more likely to cause irritation to sensitive skin and it’s best to gradually add them to your beauty routine and consult a dermatologist if irritation develops. To help skin retain moisture, hyaluronic acid is a good choice for all skin types. Oleic and linoleic acids are also good choices to seal moisture into the skin, the latter being best for acne-prone skin.

Acne is caused by sebum and debris that clog pores. It is often accompanied by oily skin with large pores. To keep pores as clean as possible, use salicylic and/or mandelic acid. Salicylic acid is a type of beta-hydroxy acid (BHA) that penetrates deep into the pores and helps with white and blackheads, but not cystic acne. Mandelic acid is an alpha-hydroxy acid (AHA), with antimicrobial effects to combat cystic acne, and is suitable for sensitive skin.

Dark spots, or hyperpigmentation, are caused when skin accumulates melanin. Kojic acid, derived from mushrooms native to Japan, inhibits melanin production and lightens skin Those with sensitive skin may prefer the gentler lactic acid and will benefit from its additional moisturizing properties.

Rosacea causes the skin to become irritated with patches of redness and dilated blood vessels and has no known cause. Unfortunately, most facial acids will only cause further irritation and redness and are not suitable for rosacea. Azelaic acid, which has anti-inflammatory effects, is an exception. It can decrease the redness and irritation and can be used by acne sufferers as well.

Dry skin leads to a dull complexion, with an accumulation of dead skin cells on the surface. It can also be sensitive. Lactic acid will gently brighten your complexion by exfoliating dead skin while helping to retain moisture. To help skin attract moisture and plump up parched skin cells, try hyaluronic acid. Oleic and linoleic acid, naturally occurring fatty acids, will help seal in moisture. The latter is good for those who suffer from both dry skin and acne.
