Alpha Hydroxy Acids An Important Part Of Skin Care

Alpha hydroxy acids (AHAs) are acids that have been derived from fruit or milk. They’ve been used for thousands of years as skin beneficial ingredients. In fact, Cleopatra is reported to have bathed in sour milk (full of lactic acid) to improve her skin.

Today, you’ll find alpha hydroxy acids in range of skin care preparations where they are included to help improve a range of skin care conditions including dry skin, wrinkles, fine lines, skin discoloration and freeing pores of clogged cells.

Widely used alpha hydroxy acids include:

Glycolic acid – derived from sugar cane
Lactic acid – derived from milk
Malic acid – derived from apples and pears
Mandelic acid – derived from almonds
Tartaric acid – derived from grapes
Citric acid – derived from citrus fruits

The most well known alpha hydroxy acids are glycolic acid and lactic acid. Both acids can penetrate skin well and are backed up by numerous clinical studies regarding their effectiveness. However, the use of other alpha hydroxy acids including malic and mandelic acid is becoming more widespread. Glycolic acid, while effective, may be problematic in darker skin types where instances of skin discoloration have occurred. Lactic acid and mandelic or malic acids seem to be better tolerated by more sensitive skin types.

How Do Alpha Hydroxy Acids Work?

Alpha hydroxy acids work mainly as exfoliants, causing dead skin cells in the epidermis or skin’s top layer, to separate from one another. The result is skin that sloughs off and can be removed easily allowing new skin cells to resurface. Studies have shown that alpha hydroxy acids may also encourage elastin and collagen production, two components that contribute to firm, smooth and toned skin. Skin benefits associated with alpha hydroxy acids include an improvement in wrinkles, skin roughness, skin discoloration and sun damage. Though benefits will be noticeable soon after use, best results are obtained over the course of several months.

Studies have shown alpha hydroxy acids to be most effective at concentrations above 8%. Concentrations above 15 – 20% are generally best left to be administered by qualified specialists because of side effects that may be associated with their use. And, they should also be formulated at a low ph in order for them to exert beneficial effect. Concentrations below 8% are a good way to gradually introduce an alpha hydroxy acid into your regimen, without over sensitizing skin. While cleansers and toners formulated with alpha hydroxy acids are certainly useful, you’ll get the most benefit from serums, creams and lotions because they remain on the skin longer.

Benefits of Alpha Hydroxy Acids

• AHA’s dissolve the glue like lipids holding dead cells together.

• When dead cells are decreased, fewer cracks and fissures can lead to irritation.

• Surface lines even out.

• Dead cells plugging pores dissolve.

• Pigment that has built up in surface skin is removed.

• Cell renewal is returned to a rate of 30 years of age.

• Increased cell renewal causes cells to become denser and more compact, making your skin a more effective barrier to outside irritants.

• AHA's have a dermal effect that influence the formation of collagen. Alpha hydroxy acids, on topical application to photoaged skin, have been shown to substantially increase skin thickness. Skin biopsies revealed increased synthesis of mucopolysaccharides and collagen as well.

• Denser skin means moisture is held in and skin becomes more pliable and supple.

• With the outer layer, corneum, less clogged and “cross-linked” with dead skin cells, the skin becomes nourished and moisturized from below, allowing the skin to become more elastic and less wrinkled.

• AHAs increase the acidity of skin, which helps cell renewal.

Researchers have found the best results for cell renewal are seen between 3pH and 4pH with no benefits other than hydration noted above 5pH. (Walter Smith, PH.D Biochemist and Researcher).

AHA's penetrate the skin to a deeper layer than Salicylic Acid or Microdermabrasion to stimulate new collagen production. Salicylic acid works from the uppermost layer of the skin, dissolving skin layer by layer. It is especially useful for thorough cleansing of the pores (which is why it is excellent for Acne and Blackhead removal).

Mechanical Scrubs work only to remove already loosened skin cells on the upper layer of skin. So, Glycolic Acid and other Alpha hydroxy acids work at the lowermost levels of the stratum corneum. It appears that AHA's modulate new stratum corneum formation by weakening the bonds between corneocytes (a type of skin cell) at the lowest levels of the stratum corneum. This activity on the formation encourages a smoother, flatter cell layout in the stratum corneum, and thus smoother, firmer skin on the surface. In conclusion, while Salicylic Acid and Microdermabrasion are beneficial for exfoliating the skin, Glycolic Acid and other AHA's go a step further by actually penetrating the skin to stimulate new collagen and elastin growth. This results in firmer, smoother skin on the surface.

While it is true that the exfoliating nature of AHA's contribute to softer skin that is more even in tone, the clinical effects of AHA's in modifying wrinkles and photoaging are due to increased skin thickness and new collagen formation.

Improvements in wrinkles are not due to inflammation or any edema formation (excess accumulation of fluid in tissue spaces). Examination of biopsied skin specimens before and after treatment with AHA's have confirmed that skin plumpness and other beneficial effects are sustained long after discontinuation of topical treatment.

Side Effects of Alpha Hydroxy Acids

Alpha hydroxy acids are acids, so there is the potential for skin irritation that may lead to redness, itchiness or pain. Alpha hydroxy acids also increase skin’s sensitivity to sunlight and therefore more prone to sunburn. For this reason, the use of a broad spectrum UVA/UVB blocking sunscreen while using any alpha hydroxy preparation is essential.

Used correctly however, alpha hydroxy acids do not increase sun sensitivity. Sun sensitivity occurs when skin is irritated and inflammation occurs. Those with very fair coloring are especially susceptible to this since their skin tends to be more sensitive. Avoiding high concentrations (15% or more) or products with pH's lower than 3 can help avoid this. For those with more sensitive skin, use of a non-irritating AHA such as lactic acid will help one avoid this problem.

Individuals with medium to darker skin tones may also be at risk of scarring pigment changes with alpha hydroxy acids. Certain alpha hydroxy acids, including lactic, malic and mandelic acids may be less problematic in these skin types.


Alpha hydroxy acids, and glycolic acid in particular, are an important part of skin care. When used appropriately, they have been shown to correct mottled dyspigmentation, melasma and wrinkles. They seem to affect skin cells deeper than their proposed penetration into the skin suggesting that their benefits are more than those just related to skin exfoliation. As such, AHAs deserve our attention and key place in the overall skin care management.
