As a rule, AHAs are best for normal to dry, sun-damaged skin because they only exfoliate on the very surface of skin rather than penetrating inside the pore. AHAs have research showing they improve collagen production and increase skin’s moisture-binding ability. My 8% Alpha Hydroxy Acid Gel is a great option for all skin types and can be worn under a moisturizer without feeling heavy or layered with product. I’ve listed other well-formulated AHA products on my subscription-based Web site, www. Beautypedia. com.
BHA also exfoliates on the surface of skin but has extra properties that make it better for normal to oily or combination skin—and especially blemish – prone skin. Salicylic acid can exfoliate inside the pore and it has anti-inflammatory and mild antibacterial benefits as well.
First-time users of a BHA product can begin with a 1% concentration of salicylic acid; those with oily to very oily skin and stubborn blackheads or blemishes should begin with a 2% concentration. Once you know the concentration you want to try, the only thing left to decide is whether you want a gel, liquid (2% strength only), or lotion texture.
Generally, if you have normal to oily skin with moderate breakouts a gel is a great place to start. If you have very oily skin with moderate to severe breakouts a liquid without alcohol or irritating plant extracts is a great option. If you have normal to combination skin lotions are a wonderful option. Which one to choose? That depends on your personal preference and experimenting to see what works best for you. I offer several BHA options in my line (more than any other cosmetic line I’ve ever reviewed) and provide a list of the best BHA products on my Beautypedia Web site.
