Why does my moisturiser sting? A gentle guide

You wash your face gently, reach for the moisturiser that promised comfort, and within seconds it burns. Your cheeks go hot and tight, and the product meant to help feels like it's making everything worse.

If that sounds familiar, you're far from alone. "Why does my moisturiser sting?" is one of the questions I hear most from people with eczema, rosacea, PD and generally reactive skin. Stinging usually has a reason, and once you understand it, choosing products gets a lot less stressful.

Why moisturiser stings sensitive skin

Think of your skin barrier as a brick wall. Skin cells are the bricks, and natural lipids are the mortar. When it's healthy, it keeps moisture in and irritants out.

When the barrier is stressed, through eczema, over-cleansing, cold weather, central heating or simply too many products, little gaps appear in the mortar. Ingredients that healthy skin would barely notice can then slip through more easily and reach the nerve endings underneath. That's the sting.

So a stinging moisturiser doesn't always mean the product is "bad". Often it means your skin is asking for something simpler while it settles.

The usual suspects on the label

Some ingredients are more likely to cause trouble on skin that's already struggling.

Fragrance (including "natural" fragrance)

Fragrance is one of the most common reasons sensitive skin reacts, and the NHS lists fragrances among the common causes of contact dermatitis. The tricky part is that a single word on the label, "parfum", can hide dozens of individual ingredients.

Essential oils count too. They're plant-derived, but they're still fragrance, and reactive skin doesn't always appreciate them.

Alcohol

Look for "alcohol denat." or "SD alcohol" high up the ingredient list. It helps products feel light and absorb quickly, but it can be drying and is a common cause of that instant hot, prickly feeling. Fatty alcohols such as cetyl or cetearyl alcohol are a different thing entirely and are generally gentle.

Active ingredients

Acids (glycolic, lactic, salicylic), retinoids and some forms of vitamin C are popular in "glow" and anti-ageing moisturisers. They can be brilliant on robust skin, but on a compromised barrier they often tingle or burn.

Humectants and some emollient ingredients

Ingredients such as urea and lactic acid draw moisture into the skin and appear in some creams for very dry skin. On cracked or broken skin, they can sting. If it's a prescribed emollient that stings, please don't just stop using it. Speak to your GP or pharmacist, as there are usually alternatives they can suggest. The NHS page on emollients is a helpful starting point.

Long ingredient lists

Every extra ingredient is one more thing your skin has to tolerate, and with 30 or 40 on the label it's almost impossible to find the culprit.

Our guide to reading an ingredient list explains the most common names in plain English.

Stinging, irritation or allergy?

A brief tingle that fades within a minute or so is often just a stressed barrier reacting. A reaction that lingers, spreads, swells, blisters or gets worse with each use is different. That can be a sign of irritant or allergic contact dermatitis, and it's worth getting properly checked.

Please see your GP or a pharmacist if:

• the stinging doesn't settle once you stop using the product
• your skin swells, blisters, weeps or becomes very red
• you're reacting to lots of different products
• the reaction is around your eyes or lips and isn't easing

Your GP can refer you for patch testing with a dermatologist if they suspect an allergy. The British Association of Dermatologists has patient leaflets on contact dermatitis and patch testing that explain what's involved.

How to patch test a new moisturiser

Before putting anything new on your face, try it somewhere less sensitive first.

1. Apply a small amount to the inside of your forearm or just behind your ear.
2. Do this once or twice a day for a few days, leaving it on as you normally would.
3. Watch for redness, itching, bumps or stinging.
4. If all is calm, try a small patch along your jawline before using it all over.

Introduce one new product at a time, so if something reacts, you'll know exactly what it was.

What to look for in a fragrance-free moisturiser for sensitive skin

Whether you're shopping on the high street or online here in the UK, this is what I'd look for:

• Truly fragrance-free. Nothing hidden behind "parfum", and no essential oils.
• A short ingredient list you can actually read and understand.
• No denatured alcohol near the top of the list.
• No acids or retinoids while your skin is reactive. You can always add them back later once it feels calmer.
• Full INCI listing, so you know exactly what you're putting on your skin.

I'd also gently suggest stepping back from big routines for a while. Fewer products give your barrier room to settle, and you can build back up slowly.

Why I went waterless and minimal

I started Apothecary & Me after watching my daughter Scarlett's skin struggle for years. Her eczema spread to her face, especially around her eyes, and so many products stung the moment they touched her skin. As a trained aromatherapist, I started formulating at home, testing on myself and on Scarlett, and keeping things as simple as I possibly could.

That's how No.1 Illuminate Face Oil came about. It has just three ingredients: jojoba, argan and vitamin E. It's fragrance-free with no essential oils, and it's waterless, so there are no fillers and every ingredient has a job to do. It also cleanses, removes makeup and moisturises, which means one product touching your skin instead of three.

For skin that's very dry, cracked or raw, No.3 Calm Butter is the richer option. It's an unscented, mango butter-based balm for face and body, and it's the one we recommend for children's reactive skin too.

A quick note: our oils and butter are designed to be used on their own, not layered over water-based creams.

Many people tell us they notice their skin feeling more comfortable within a few weeks, with more settled results over two to four months. Every skin is different, which is why everything comes with our promise: clear skin, real relief, or your money back if it doesn't suit your skin.

If you'd like to try it, Illuminate is a lovely place to start. And if you're not sure which would suit your skin, just drop me a message. I read every one.

FAQs

Is it normal for moisturiser to sting?

A brief tingle can happen when your barrier is stressed, but moisturiser shouldn't hurt. If it stings every time or leaves your skin redder than before, try something simpler or speak to a pharmacist.

Why does my moisturiser sting all of a sudden?

Usually your skin has changed rather than the product. A flare, a new cleanser, over-exfoliating or central heating can all leave the barrier more vulnerable. It's also worth checking whether the formula has changed.

Does fragrance-free mean unscented?

Not always. "Unscented" can mean a masking fragrance has been added to cover other smells. The only way to be sure is to check the ingredient list for "parfum", "fragrance" or essential oils.

Should I keep using a moisturiser if it stings?

If you bought it yourself and it keeps stinging, stop and give your skin a rest. If it's prescribed, speak to your GP or pharmacist before stopping. They can suggest an alternative.
