Skin naturally sheds billions of cells every day. It is said that 90% of household dust is made up of dead skin cells. As we age, this natural shedding slows or stops due to many factors such as sun damage, dry skin, oily skin, genetics, or skin disorders. The results of this are dull, dry or flaky skin, clogged pores, blemishes, and uneven skin tone.
Exfoliation is key in helping skin balance itself. Getting rid of skin cell build up can undo the effects experienced by skin cell shedding slowing down.
Exfoliation helps your skin look younger, promote blood flow and circulation, promote collagen production, and improve skin health. But, with all the exfoliating products out there, how do we know which to use and which is appropriate for our skin type and need?
To understand which to use we must understand how they work and what skin types and conditions are appropriate for each category.
What’s The Difference Between AHA And BHA?
As an esthetician, I’m always asked what the difference between AHA and BHA.
Alpha Hydroxy Acid, AHA, are acids derived from natural substances such as sugar cane, milk, grapes etc. They work by melting the intercellular glue that holds our skin cells together. AHA are water loving and water soluble acids and their molecular structure is small.
AHAs are preferred for sun-damaged and dry skin because they exfoliate on the surface of skin and have the added benefit of also improving moisture content, but they do not penetrate as deep as BHA and the effects are concentrated on the surface of the skin.
