Why does my skincare sting? Causes and what to do

A stinging, burning or prickling feeling after you put something on your face is your skin telling you it is irritated. Sometimes the product is too strong. Sometimes the skin under it is dry or damaged, so even a plain moisturizer stings. And sometimes it is an allergy. This guide explains each cause, what a short sting means compared with one that lasts, and when to stop a product or see a doctor. It is part of Skinli's guide to a damaged skin barrier.

Skinli gives general education and is not a doctor.

What the sources say stinging means

The American Academy of Dermatology (AAD) gives a plain rule for store products: "Stop using a product that stings, burns, or tingles. These sensations mean that the product irritates your skin." It adds one exception. Some prescription-strength products will burn or sting, so if a dermatologist prescribed it, ask whether this should be happening before you stop.

The NHS describes the mildest form of irritant contact dermatitis, the skin reaction to an irritating substance, as "mild dryness, redness, burning or stinging." So a sting sits at the gentle end of the same reaction that, when stronger, causes painful blisters.

The five usual causes

1. Your skin barrier is damaged

Your skin barrier is the top layer of skin that keeps water in and irritants out. The AAD says an overused exfoliator can damage it, and that "a damaged skin barrier leaves you with raw and irritated skin." Raw skin stings with almost anything. The AAD says dry, cracked or raw skin often feels painful, and some people feel it burn when water touches it.

The clue is that gentle products you have used for months start to sting. Skinli's guide to the signs of a damaged skin barrier lists the others.

2. An ingredient irritates you

Some ingredients sting more than others:

Ingredient	What the source says
Alcohol, menthol, spices, lime	MedlinePlus says products with these "can sting your skin", especially when you first use tretinoin
Fragrance	The AAD says fragrances can be irritating to dry skin
Glycolic and lactic acid	The FDA calls these the most common AHAs and received reports of burning, rash and swelling from AHA products
Salicylic acid	The FDA says to stop a product with this acid, a BHA, if you have irritation or prolonged stinging
Sodium lauryl sulfate	The NHS says this foaming ingredient can cause burning, stinging, itching and redness
Tretinoin and adapalene	Their labels list burning or stinging among side effects, most often in the first weeks

3. You applied it to damp skin

The AAD's rosacea advice is to wait until your face is dry after washing, because "when you apply moisturizer to dry skin, it's less likely to burn or sting." Tretinoin labels say to wait 20 to 30 minutes after washing before applying it. Skinli's plan waits until the face is fully dry before the acne gels for the same reason.

4. You have sensitive skin

Some people's skin stings easily even when it looks normal. A 2017 expert group defined sensitive skin as stinging, burning, pain, itching or tingling in response to things that should not cause these feelings, which cannot be explained by a skin disease. Skinli's guide to sensitive skin covers how to choose products when this is you.

5. You are allergic to something in it

An allergy is less common than irritation. MedlinePlus explains that you do not react the first time you meet an allergen, that you can use a product for years before an allergy develops, and that the rash most often appears 24 to 48 hours after contact. Itch is the main symptom of an allergic reaction, and MedlinePlus says it can be severe.

A sting that fades, or one that lasts

What happens	What it likely means	What to do
A brief sting with a new acne or acid product that fades soon after	Mild irritation	Use it less often, apply to dry skin, moisturize
Stinging from a moisturizer or cleanser that never stung before	A damaged skin barrier	Stop active products for now, keep the routine plain
Burning that lasts, with redness or peeling	Irritant contact dermatitis	Wash it off, stop it, see a doctor if it does not settle
Itch and a rash hours or days later	Possible allergy	Stop it, see a doctor, ask about patch testing
Swelling of lips, tongue or throat, trouble breathing	Anaphylaxis, a life-threatening allergic reaction	Call emergency services

The NHS gives a time limit for moisturizers and wash products that stop you getting dry: burning or stinging that does not settle after a few days of treatment is usually caused by a reaction to an ingredient, and is a reason to talk to a pharmacist or doctor.

What to do tonight

1. Wash it off gently. The AAD says to wash the product off as soon as possible and not use it again, then apply a cool compress or petroleum jelly if needed.
2. Stop your active products. That means acids, retinoids, benzoyl peroxide, scrubs and peels. Keep a gentle cleanser, a plain moisturizer and sunscreen. Skinli's guides to gentle cleansers and moisturizers for a damaged skin barrier explain what to look for.
3. Moisturize on dry skin. Pat your face dry first, as the AAD's rosacea advice says, then apply the moisturizer.
4. Wait until nothing stings. Skinli's approach is at least a week on the plain routine. The step by step repair guide explains the rest.
5. Bring products back one at a time. The AAD says using several products at the same time can irritate your skin, and advises testing a product on a small area first. Its home test is to apply the product to one spot twice a day for seven to 10 days. Skinli's guide to patch testing gives the steps.

Products that tend to sting less

The AAD's advice for rosacea, a condition where skin stings easily, gives a useful list of what to look for in products for any skin that stings:

• Fragrance-free products. The AAD says an unscented product can still contain chemicals that hide the smell of other ingredients, and these can irritate dry, sensitive skin.
• A cream instead of a lotion or gel. The AAD recommends a cream for skin with rosacea.
• No astringent or toner. The AAD says never to use one on skin with rosacea.
• A mineral sunscreen if yours stings. The AAD suggests one with zinc oxide, titanium dioxide or both, with silicone (often listed as dimethicone), and with no fragrance.
• Rinse the cleanser off well. The AAD says cleanser left on the skin can cause irritation.

The AAD says even products labeled hypoallergenic can cause a skin reaction, so test each new one on a small area first.

If a prescription product stings

Prescription acne medicines often sting at first. The Retin-A Micro label says irritation scores for redness, peeling, dryness, burning or stinging, and itching "peaked during the initial two weeks of therapy and decreased thereafter." Do not stop a prescription on your own. Tell the doctor who prescribed it. The Retin-A label says the doctor can have you use it less often or pause it, and says to pause or adjust it if the skin becomes red, swollen, blistered or crusted. Skinli's guide to tretinoin purging covers the first weeks on tretinoin.

Why does it sting all of a sudden?

If a routine you have used for months starts to sting, think about the last two to four weeks. The AAD says that people who damage their skin barrier by overusing exfoliating products "may develop allergic reactions to products that previously didn't cause a problem." Cold, dry weather also dries the skin, and the AAD lists stinging among the signs of skin that is excessively dry. Other common triggers are a new acid or retinoid, exfoliating more often, and starting a second acne treatment. Stop the most recent change first.

When to see a doctor

See a doctor or pharmacist if:

• Burning or stinging does not settle after you stop the product.
• Your skin blisters, swells, weeps fluid, or develops yellow crusts.
• A rash spreads beyond where you applied the product.
• Dry skin becomes painful, cracked or bleeding, which the AAD says is a reason to see a dermatologist.

The AAD's advice on facial masks applies to any product: wash it off right away if you feel itching, burning or stinging, because this could be a sign of irritation or an allergy. Call emergency services at once for swelling of the lips, tongue or throat, or trouble breathing, which the NHS lists as signs of anaphylaxis.
