Think exfoliating products are just a sales gimmick? Dermatologists say they really do help you get a healthy glow on. Read on to learn how to make the most of a scrub…
Drugstore beauty aisles are full of products claiming to exfoliate skin, but many women don’t know how and when to scrub. Or what it actually does for complexions.
Turns out, it’s a key way to keep skin soft and glowing. Especially as we age.
Here’s why exfoliating helps: The top tier of skin (the epidermis) is made of layers of dead, flattened cells. Over roughly four weeks, these move from the bottom of the epidermis to its surface, where they naturally fall off, exposing newer, fresher-looking skin underneath.
But as we age, our body’s ability to shed dead cells slows, leaving skin looking dull. That’s why kids have a rosy radiance and many adults don’t.
By removing the topmost layer, exfoliating speeds up the skin’s shedding process, says New York City-based dermatologist Doris Day, M.D., author of Forget the Facelift (Avery).
But exfoliating too often or using the wrong products may dry out or irritate skin.
So how do you make sure you don’t rub skin the wrong way? Read on for the dermatologists’ top do’s and don’ts.
Do know what exfoliating does for your skin.
A gentle scrubbing offers more than a temporary rosiness and softer, smoother skin.
Over the long term, regular exfoliation “can visibly minimize pores and rejuvenate the skin’s surface,” says Patricia Wexler, M.D., associate clinical professor of dermatology at Mount Sinai College of Medicine in New York.
Exposing fresher cells evens out texture and tone – including acne scars – and unclogs pores. And it makes pigmentation and fine lines less noticeable, because you’re removing some discolored, sun-damaged skin.
Exfoliating can also boost penetration of other skin products – those that moisturize or fight wrinkles, acne and discoloration. It also makes self-tanners look more natural and last longer.
Don’t think all exfoliants are created equal.
Exfoliants fall into two categories: physical and chemical. To understand their differences, imagine a sink of dirty pots and pans. Both a scouring pad and dish soap will clean them, but in different ways.
Physical exfoliants (also called mechanical exfoliants) use gritty materials – beads, grainy scrubs, loofahs and even shaving – to send dead skin packing.
Chemical, or liquid, exfoliants use a mild acid to dissolve the “glue” that binds dead cells to the skin’s surface, Day says. These include beta hydroxy acids (salicylic is one) and alpha hydroxy acids, such as glycolic and lactic.
Which is best for you? It depends on your skin type.
If you have extremely dry, sensitive or acne-prone skin, choose chemical exfoliants over grainy scrubs. The latter can be too abrasive, leaving skin inflamed and irritated.
Salicylic acid is particularly good for acne sufferers because “it exfoliates the surface layer of dead skin cells and cleanses away acne-forming bacteria,” Day says.
And whatever your skin type, use physical scrubs with ground fruit pits, nuts or shells only on your body, not your face. These may sound safe because they’re made with natural ingredients, but they can tear delicate facial skin with their harsh, jagged edges, exacerbating acne and other skin conditions.
Do know when to exfoliate.
All skin types benefit from a good scrubbing, Wexler says.
“I advise all my clients to exfoliate regularly, no matter their skin condition – whether aging, acne-prone or sensitive – for optimum cell renewal and a glowing complexion,” she says.
But how often you exfoliate depends on your skin type. If your face is oily, exfoliate at least once a week.
Women with drier, more sensitive skin should stick to only once a week or every two weeks, Day advises.
Body parts like knees, elbows, ankles and feet can be rubbed and scrubbed every other day. That’s because skin is thicker in these areas and can tolerate more friction. Plus, dead, dry skin cells tend to pile up there.
But don't scrub if you have an active infection, cold sore, sunburn, extremely dry skin, redness or inflammation for any reason. Let skin heal before exfoliating or you may worsen the conditions.
Don’t overdo exfoliation.
While a little can make a big difference in your complexion, over-exfoliating can damage skin, aggravating acne or increasing dryness.
That’s because dead surface cells retain moisture, “so constantly removing this protective layer keeps it from staying hydrated,” says Manhattan based-dermatologist Paul Jarrod Frank, M.D., associate professor of dermatology at New York University Medical Center.
You’ve gone too far “if skin bleeds, stings or burns after exfoliating. That’s a sign “you've over-stripped the outer layer of skin,” Day says.
Another common problem: Using too many exfoliants at once. It’s an easy mistake. How many times have you washed your face with a physical exfoliant (like a loofah or grainy scrub) and then applied a chemical exfoliant (a skin cream with alpha-hydroxy-acids)?
Do know how to exfoliate.
Pretty much every body part can be exfoliated, but here are tips to make it more effective.
On your face, use a light hand and apply exfoliant to damp skin – it causes too much friction on dry skin.
Exfoliate your lips with a toothbrush, washcloth or an exfoliant made for lips to remove dry flakes and boost blood circulation.
Dry brush the rest of your body three times a week before stepping in the shower, advises Susan Ciminelli, owner of the Susan Ciminelli Day Spa in New York City and author of The Ciminelli Solution: A Seven-Day Plan for Radiant Skin (William Morrow).
Use a natural-bristle body brush, loofah sponge or loofah gloves (all available at a health food store and some drugstores); they’re not as harsh than synthetic versions.
Start at your feet, using gentle, circular, counter-clockwise motions, and work your way up legs to the torso, chest and arms.
Don’t assume you have to use expensive products.
Physical and chemical exfoliants are sold in a variety of price ranges at drugstores and department stores.
In fact, you might have all the ingredients for an effective scrub right in your kitchen.
“Oatmeal is one of my favorite ingredients because it’s gentle in abrading off the upper layers of skin cells,” Day says. “It’s excellent for all skin types, including acne-prone and sensitive skin.”
Here are two do-it-yourself scrubs Day recommends:
Oatmeal-Aloe Vera Facial Scrub
1/2 cup coarsely ground, raw oatmeal
1/4 cup organic honey
1 teaspoon extra-virgin olive oil
1 teaspoon aloe vera gel
2 teaspoons water
1. Mix all ingredients in a small bowl. Apply to face and neck with gentle, circular strokes for about a minute. Rinse with lukewarm tap water or wipe off with a warm, damp washcloth.
Finish with a splash of cold tap water to tighten pores, and pat dry.
Oatmeal-Salt Body Scrub
1/2 cup sea salt
1/4 cup ground, uncooked oatmeal
6 tablespoons flaxseed oil
1 tablespoon extra-virgin olive oil
8 drops geranium oil
Mix all ingredients in a small bowl. Massage over your body and feet in the bath or shower for a few minutes. Finish with a rinse of cool water and pat skin dry.
Do care for skin after exfoliating.
Because exfoliating makes other products penetrate better, be careful with lotions and potions that you apply afterward.
If your skin gets too sensitive to them after exfoliating, apply them on days you don’t scrub.
If you have skin dry skin, apply moisturizer immediately after exfoliating so it really soaks in.
Headed outside? Freshly exfoliated skin is more sun-sensitive – because you’re removing the epidermis’ top layer – which increases the risk of sun damage and sunburn.
Be extra vigilant about avoiding the sun and using a broad-spectrum sunscreen (that protects against ultraviolet A and B rays) daily.
