Why does skincare sting around my nose but not elsewhere?

Why can just one patch sting?

Irritant contact dermatitis means inflammation caused by something damaging the skin's outer barrier. It usually stays where the irritation occurs. Friction, soaps, acids and repeated exposure to water can contribute; retinoids and benzoyl peroxide can also irritate skin. Several irritants can add up rather than one product being solely responsible. Existing skin damage increases susceptibility, which helps explain why the same application can feel different across your face. Burning or pain is more typical than itching, and repeated irritation can start with dryness and cracking.1

What else should you look for?

• An itchy rash after a product can be allergic contact dermatitis rather than direct irritation. Allergic reactions often appear 24 to 48 hours after exposure, and an allergy can develop after years of tolerating a product.
• Many small pimple like bumps clustered around the nose, with burning or itching, can be perinasal dermatitis. This is the nose area form of perioral dermatitis, not necessarily acne.
• Redness in the centre of your face, sensitive skin and acne like bumps can point toward rosacea. The redness can come and go or remain, and eyes can feel gritty.
• Inflammation is not always bright red. Contact dermatitis can look dark brown, purple or grey on darker skin.

What should you do when skincare stings?

1. 1Stop applying the suspected irritant to the affected area. If the product is still on your skin, gently rinse it away with warm water. Avoid further exposure rather than repeatedly testing the sore patch.
2. 2Use gentle cleansing rather than scrubbing. For rosacea prone skin, use a mild cleanser morning and evening, apply and rinse with your fingertips, then pat dry. Rinse thoroughly because leftover cleanser can irritate.
3. 3Apply a gentle moisturizer. For rosacea prone skin that burns during moisturizing, wait until your face is dry first. If you use prescribed rosacea medication, apply the medication before moisturizer.
4. 4If rosacea is a possibility, stop exfoliating and avoid toners. Choose fragrance free products rather than products labelled unscented, and favour a cream over a lotion or gel.
5. 5If you have rosacea, protect your skin from sunlight with shade, protective clothing and a water resistant, broad spectrum sunscreen with SPF 30 or higher. If sunscreen irritates, look for a fragrance free mineral option containing zinc oxide or titanium dioxide.

Moisturizer helps skin repair itself, which is a more useful job than giving the routine another dramatic product name, although "Nose Rescue" practically writes its own launch campaign. For contact dermatitis, a pharmacist can help you choose an emollient, meaning a moisturizer that prevents dryness.34

How long should it take to settle?

Contact dermatitis clears in two or three weeks in most cases, though an allergic rash can persist for weeks after exposure stops. Avoiding the cause helps prevent a return. Perinasal dermatitis needs a different approach: without treatment, it can last months or years.23

When should you get it checked?

See a doctor for persistent, recurring or severe symptoms, or if treatment is not helping. Seek medical care for signs of infection such as tenderness, warmth, redness or fever. A dermatologist can distinguish acne from a nose area rash and arrange allergy patch testing when needed.234

Patch testing can help identify an allergy trigger.3
