How to Exfoliate Skin (and Why It's So Important)
How Exfoliation Works
We naturally shed dead skin every day, but this shedding process can come to a screeching halt between midlife changes, having oily or dry skin, and other problems certain skin concerns cause.
The not-too-pretty results of all this are dull, dry, or flaky skin; clogged, enlarged pores; plus bumps, wrinkles, loss of firmness, and uneven skin tone.
When you gently eliminate this unattractive dead skin, all of the issues mentioned above can become a distant memory! That’s where AHA (alpha hydroxy acids, such as glycolic acid and lactic acid) and BHA (beta hydroxy acid, also known as salicylic acid) exfoliants come into play.
The Difference Between AHA and BHA Exfoliants
When properly formulated, AHA and BHA exfoliants have a lot in common in regards to their potential for boosting hydration, minimizing the appearance of wrinkles, and delivering firmer-looking skin. Both can also help even out skin tone and smooth away rough skin. However, each also has unique qualities you’ll want to consider when deciding which one to use.
- AHAs are best if rough, crepey skin, with loss of firmness are your concerns. It is especially helpful for addressing advanced signs of aging and dry skin. Our RESIST Daily Smoothing Treatment with 5% AHA is an outstanding option that will give you hydrated plumper-looking skin and an ultra-smooth healthy glow.
- BHA is also preferred for those struggling with sensitive skin and redness. Not everyone with temperamental skin can tolerate an exfoliant, but a BHA is the best option to gain all the benefits a leave-on exfoliant can provide as well as calm red areas and enhance smoother skin. If that sounds like your skin type try our ultra-gentle CALM Redness Relief 1% BHA Lotion Exfoliant.
Tips on Getting the Most from Your AHA or BHA Exfoliant
- You do not need to wait for your AHA or BHA to dry—you can apply any other product in your routine, such as moisturizer, serum, eye cream, or sunscreen, immediately afterwards.
- Experiment with different strengths of AHA and BHA to see which concentration gives you the best results. Consider adding a "weekly" (higher strength) AHA or BHA when you want to take your exfoliation to the next level.
- Apply your AHA or BHA exfoliant around the eye area, but not on the eyelid or directly under the eye (along the lower lash line). This can help soften the appearance of fine lines and wrinkles, as well as enhance the penetration of anti-aging ingredients you apply after your AHA or BHA.
- How often you should exfoliate depends on your skin type and skin concerns. For some people that can mean using your AHA or BHA exfoliant twice a day, once a day (like Paula), or every other day. You will probably need to experiment to see what works best for you.
Why Not Just Use a Scrub or Cleansing Brush?
Not only are scrubs and cleansing brushes not as effective as AHA or BHA at exfoliating skin gently, they can also aggravate skin by being too abrasive. Many scrubs have a rough, coarse, uneven texture that are harsh on skin and many cleansing brushes have stiff bristles which can have the same negative impact.
Gentle scrubs and soft cleansing brushes can be an option, but even then, they are best thought of as an extra cleansing step because abrasively trying to exfoliate dead skin is not the natural way your skin used to shed when you were young.
Exfoliation from the Neck Down
AHA and BHA exfoliants can be just as helpful for your body as they are for your face—but such products are nearly impossible to find; instead, you’ll come across countless body scrubs and loofahs, which can cause as much harm from the neck down as they can for face (abrasion isn’t healthy for skin, period). From the neck down, non-abrasive AHA or BHA products that are gentle reveal healthy skin naturally and imperceptibly.
This surprising lack of options and the research about how great AHA and BHA are for skin led us to formulate two body exfoliants for Paula’s Choice your body will welcome with overnight results: RESIST Skin Revealing 10% AHA Body Lotion, which is great for smoothing and hydrating dry, crepe-like skin texture that’s also uneven, and RESIST Weightless Body Treatment with 2% BHA, an oil-free lotion that perfectly smooths rough, bumpy skin—including hard, raised bumps that tend to be red and can feel uncomfortable.
What about acne breakouts on the body? We have an ideal exfoliant for that, too! Our oil- and alcohol-free CLEAR Acne Body Spray makes quick work of acne and blackheads from the neck down, and its super-light, spray-on formula couldn’t be easier to use.
