AHA or BHA, which one is better?

August 1, 2012 (Wed)  |  By Administrator  |  In Research
We’ve all heard about AHAs and BHAs and how important they are for the youthful look of your skin but few know what is the difference between them, how do they work and for what particular skin types or skin problems they are most suitable. All these will be revealed below so keep reading.What is the difference between AHA and BHA?

Alpha Hydroxy Acid , AHA in short, are acids derived from fruits that have skin rejuvenating properties. The most known AHAs are Glycolic, Lactic, Citric, Malic and Tartaric Acids and they are widely spread on skin care formulations for different types of problems as they promote the turnover of new skin cells. How do they work? They work by melting down the intracellular “glue” allowing dead-skin cells to be removed from the surface of the skin.

Unlike AHAs, Beta Hydroxy Acid or BHA is only one: salicylic acid. This is a chemical compound similar to aspirin that has been used for ages in treating a large variety of inflammatory diseases. Salicylic acid works exactly the same as AHAs, by breaking down and exfoliating dead-skin cells but the main difference between them is that Salicylic acid is oil soluble whereas AHAs are water soluble. Continue reading for more details.

Whom is AHA better for?
AHAs are water soluble making them more suitable for thickened and sun-damaged skin where breakouts don’t occur frequently. They cannot penetrate the skin as deep as BHA and their effect is felt on the surface of the skin.
AHAs work better for sun-damaged and dry skin because they exfoliate the surface layers of the skin and help skin retain more water thus improving the moisture content;
AHAs rejuvenate aging skin. Check out Cellnique’s Advanced Bio Renewal Serum for more details.

Whom is BHA better for?
As we have previously mentioned BHA, being a lipid (oil) soluble molecule, has the ability to penetrate pores filled with sebum (oil) and exfoliate them. This makes BHA particularly useful for oily, acne-prone skin.
BHA has anti-inflammatory and anti-bacterial action;
BHA is preferred for those who have sensitive skin type or sensitive skin conditions such as rosacea;
Salicylic acid is a good ingredient for local spot treatments and a good alternative to Benzoyl Peroxide because it is less harsh on skin. You can have a look at Cellnique’s Skin Action Gel Plus.
