Bumps after over-exfoliating: what they are

Over-exfoliating leaves skin red and tight, and for many people it brings bumps too: tiny rough ones, red ones, itchy ones, or a fresh crop of pimples. These bumps come in several kinds, and the right response depends on which kind you have. This guide describes the usual kinds, how to tell them apart, and what to do while your skin recovers. It is part of Skinli's guide to a damaged skin barrier, and the main guide to over-exfoliated skin covers the damage itself.

Skinli gives general education and is not a doctor. Only a doctor can diagnose a rash.

Why over-exfoliating leads to bumps

Your skin barrier is the top layer of skin that keeps water in and irritants out. Exfoliating wears it down. The American Academy of Dermatology (AAD) says that exfoliating the wrong way can "lead to increased redness or acne breakouts," and that exfoliating while you use a retinoid, retinol or benzoyl peroxide "may worsen dry skin or even cause acne breakouts."

Two things link the damage to bumps:

• Irritation. The AAD says, "Dry skin is irritated skin. Anytime you irritate your skin, you risk getting more acne." The tretinoin label makes the same point for people on acne treatment: "excessive irritation such as rubbing, too much washing, use of other medications not suggested by your physician, etc., may worsen your acne."
• Oil. The AAD explains that when skin becomes dry, the body makes more oil, and the extra oil can clog pores and lead to more breakouts.

An AAD dermatologist also warns that face masks with the wrong ingredients can damage the skin barrier and lead to "irritation, dryness, or even breakouts."

The kinds of bumps

Kind	What it looks like	When it appears	Clue
Acne breakout	Pimples, whiteheads or red bumps in your usual acne areas	After the skin has been dry and irritated	Looks like your normal acne, only more
Irritant contact dermatitis	Tiny rough bumps on red, dry skin, sometimes stinging	Straight away or within 48 hours	Only where the product touched
Allergic contact dermatitis	Itchy red bumps, sometimes small blisters	Most often 24 to 48 hours after contact	Strong itch, can spread past the product area
Perioral dermatitis	Small red or skin-colored acne-like bumps around the mouth, nose or eyes, with dry, flaky skin	Often after using a steroid cream on the face	Clears slowly, over weeks to months
Rosacea flare	Small pink or red bumps with redness across the nose and cheeks	Redness comes and goes	Water and skincare may burn or sting
Infection	Bumps with pus, yellow crusts, hot swollen skin	Any time	Pain and warmth, sometimes fever

The timing for contact dermatitis comes from the NHS, which says irritant reactions can appear straight away or within 48 hours, and from MedlinePlus, which says allergic reactions most often appear 24 to 48 hours after contact. The perioral dermatitis description comes from the AAD, and the rosacea description from the NHS.

If you started a retinoid in the same weeks, some new pimples may be the early flare that retinoid labels describe. Skinli's guide to how long skin purging lasts explains that pattern.

Contact dermatitis from exfoliating products

The NHS says contact dermatitis is caused either by an irritant, "a substance that directly damages the outer layer of skin," or by an allergen, a substance the immune system reacts to. Its list of common irritants includes acids and alkalis, soaps and detergents, and perfumes and preservatives in toiletries or cosmetics. The NHS adds that symptoms of irritant contact dermatitis can be made worse by heat, cold, rubbing and dry air, so keep the skin away from all four while it heals.

MedlinePlus says the rash may "have red bumps that may form moist, weeping blisters" and may "become scaly, raw, or thickened." The AAD says skin with contact dermatitis can feel "swollen and blistered or dry and bumpy." Itch is common, and the AAD says an intense itch or burning can come before the rash appears.

Perioral dermatitis

Perioral dermatitis often looks like acne, which is why people try to scrub it away and make it worse. The AAD says it often looks like "small, red, acne-like breakouts" on light-colored skin and skin-colored bumps on skin of color, may itch or burn, and usually comes with dry, flaky skin. It can appear around the mouth, nose or eyes.

The AAD says the cause is not entirely clear. A skin care product or toothpaste irritating the skin is one possibility, an allergy is another, and many people develop it after applying a corticosteroid cream, such as hydrocortisone, for too long. The AAD advises a mild, fragrance-free cleanser and gentle washing, stopping all corticosteroid creams (ask your doctor first if one was prescribed), and seeing a dermatologist, who often prescribes an antibiotic. It warns the rash can get worse for a while after stopping a steroid cream, and that it clears slowly. Skinli's guide to azelaic acid for perioral dermatitis covers one treatment a doctor may use.

Rosacea or over-exfoliation?

The two can look alike, and one can make the other worse. The NHS lists the first signs of rosacea as redness across the nose, cheeks, forehead, chin, neck and chest that comes and goes, and "a burning or stinging feeling when using water or skincare products." It adds that people with rosacea may get small pink or red bumps, sometimes filled with a yellowish liquid, and that the redness can be harder to see on brown or black skin.

Over-exfoliation usually follows a clear change in your routine and settles once you stop it. Rosacea is a long-term condition, so the redness keeps returning even when your routine is gentle. The AAD's advice for people with rosacea is to avoid products with glycolic acid, lactic acid, alcohol, menthol and fragrance, and to stop exfoliating. If your redness and bumps keep coming back, see a doctor. Skinli's guide to rosacea symptoms gives more detail.

Bumps on the body after scrubbing

The same pattern happens on the chest, back and arms. The AAD's advice for back acne says scrubbing skin with acne "actually worsens acne," and that antibacterial soaps, astringents and abrasive scrubs can worsen it too, along with loofahs, back brushes and buff puffs. It recommends gentle, fragrance-free products instead. If bumps appear on your body after you started a scrub, a brush or an exfoliating body wash, stop it for two to three weeks and see whether they settle.

What to do about the bumps

1. Stop every exfoliating product. Acids, scrubs, peels, brushes and retinoids, including retinol, all pause until the skin is calm.
2. Do not treat the bumps with more acid. The AAD advises people with acne to avoid astringents, toners and exfoliants, because they can dry the skin and make acne appear worse.
3. Do not pop or scrub. The AAD says scrubbing irritates acne-prone skin and worsens acne.
4. Keep a plain routine. A gentle cleanser, a moisturizer labeled non-comedogenic (made so it does not clog pores), and sunscreen. The AAD says a moisturizer can prevent the dry, irritated skin that leads to breakouts. See gentle cleansers and moisturizers for a damaged skin barrier.
5. Stop steroid creams on the face if the bumps are around your mouth, nose or eyes, and ask a doctor, as the AAD advises for perioral dermatitis.
6. Give it two to three weeks. MedlinePlus says most contact dermatitis clears in 2 or 3 weeks once the cause is avoided.

If acne is still there when the skin has healed, restart acne treatment slowly. Skinli's free acne plan starts adapalene 0.1% and benzoyl peroxide 2.5% every other night for two weeks, in a thin layer, to protect the skin barrier. Skinli's guide to the skin barrier and acne explains how to treat both at once.

When to see a doctor

See a doctor or dermatologist if:

• The bumps itch intensely, blister, weep fluid or spread beyond where you used the product.
• They have pus, yellow crusts, or the skin feels hot and swollen.
• Bumps around the mouth, nose or eyes keep coming back.
• Redness with bumps keeps returning in the middle of your face, which may be rosacea. The AAD says anything that irritates the skin can make rosacea flare.
• The bumps have not improved after two to three weeks of gentle care.

Call emergency services for swelling of the lips, tongue or throat, or trouble breathing.
