We also emphasize the important contribution of cosmetic vehicles in these types of studies. Thus, HAs play an important role in cosmetic formulations, as well as in many dermatologic applications, such as in treating photoaging, acne, ichthyosis, rosacea, pigmentation disorders, and psoriasis.

Beta hydroxy acid most prominent representatives in this class of compounds are glycolic acid, lactic acid, and salicylic acid SA Figure 1.

HA have transformed skin care since their introduction to dermatology. They are also found in corn, sugar cane and milk. They share a common chemical structure consisting of a hydroxyl group on the alpha carbon position.

Examples include malic acid, lactic acid, citric acid and glycolic acid. Video of the Day Beta hydroxy acids BHAs have beta hydroxy acid slightly different chemical structure and are less commonly used. In skin care, beta hydroxy acid acid is the main beta hydroxy acid, but also look on the label for beta hydroxy acid hydroxybutanoic acid, tropic acid or trethocanic acid.

A significant difference between the two is that alpha hydroxy acids are water soluble, while beta hydroxy acids are oil soluble. Usage Both alpha and beta hydroxy acids are becoming increasingly popular in skin care products such as toners, moisturizers, sunscreen and cleansers.

Advertising campaigns claim their effects include improved acne, a decrease in the appearance of wrinkles, diminished beta hydroxy acid pigmentation spots, moisturizing and tightening the skin, removing sun damage, and improving underlying collagen and elastic tissues in the skin. There is little if any scientific data to back up these claims, however.

Beta hydroxy acid Alpha hydroxy acids are able to decrease the strength of cell-to-cell bonding so the outer layer of dead skin, the stratum corneum, peels off in sheets.

Vitamin C in its most commonly found forms is highly unstable when exposed to oxygen, beta hydroxy acid it useless. Choose one in a tube or a pump. Also, many topical vitamin C preparations do not penetrate the skin enough to make a difference. If you are considering using a topical vitamin C preparation, ask your dermatologist which product will be the most effective for you.


Continued Hyaluronic Acid Skin care products containing hyaluronic acid are often used with vitamin C products to assist in effective penetration. Hyaluronic acid occurs naturally and quite abundantly in people and animals and is found in young skin, other tissues, and joint fluid.

Hyaluronic acid is part of the body's connective tissues, and is beta hydroxy acid to cushion and lubricate. Aging destroys hyaluronic acid. Diet and smoking can also affect your body's level of hyaluronic acid over time. Skin care products with hyaluronic acid are most frequently used to treat wrinkled skin although they don't beta hydroxy acid anything the body has naturally lost.


These are very effective moisturizers. Copper Peptide Studies have shown that beta hydroxy acid peptide promotes the production of collagen and elastin in your skin.

It also acts as an antioxidant and promotes production of glycosaminoglycans such as hyaluronic acid. Studies have also shown that copper-dependent enzymes help beta hydroxy acid, smooth, and soften the skin quicker than most other anti-aging skin care products.

In addition, copper peptides have been shown to remove damaged collagen and elastin from the skin and scar tissue.

Be wary of these claims, however, since the effects on your skin may be far less than is seen in laboratory testing. Alpha-Lipoic Acid Alpha-lipoic acid diminishes fine lines, gives skin a healthy glow, and boosts levels of other antioxidants, such as vitamin C. Alpha-lipoic acid can enter all beta hydroxy acid of a skin cell.

Due to this quality, it is believed that alpha-lipoic acid can provide more protection than other antioxidants against so-called beta hydroxy acid radicals that can damage skin.
