When Skincare Is Not Enough

Some signs need emergency care now, some need a doctor within a day or two, and some need a dermatologist appointment. Here is which is which.

Get emergency care now

If any of these happen, go to the nearest hospital emergency department or call 999. Do not wait, and do not apply home remedies.

Swelling of the face, lips, tongue or throat, trouble breathing or swallowing, or feeling faint after a product, food or medicine.
A fast-spreading rash with fever, blistering or peeling skin, or sores in the mouth or eyes, especially after starting a new medicine.
A red, hot, painful area of skin spreading quickly, with fever or chills.
A product or chemical in the eye causing pain, blurred vision or light sensitivity; rinse with clean water for a long time first.
A large area burned by a peel or chemical, with blisters or raw skin.

See a doctor within a day or two

A rash, swelling or burning that keeps getting worse, or has not eased 2 to 3 days after stopping the product.
Oozing, yellow crusts or rising pain, which may mean infection.
Sudden, severe, painful acne or swollen lumps on the face.
Burning, redness or bumps after stopping a fairness or other cream; take the cream with you.

Book a dermatologist appointment

These are not emergencies, but home skincare is not meant to fix them. Book within a few weeks, and do not delay for a changing mole.

A new or changing mole or spot: uneven shape or edge, several colours, getting bigger, itching or bleeding.
Deep painful acne or cysts under the skin, or acne leaving pits or raised scars.
Acne that has not improved after about 12 weeks of consistent care.
Matching brown patches on both cheeks, the forehead or above the lip (possibly melasma).
Lasting redness and flushing across the centre of the face, or small bumps without blackheads.
Itchy, scaly patches that do not ease after 2 to 3 weeks of moisturizer.
Acne along with irregular periods or unusual hair growth.
Your skin is affecting your sleep, work or mood; that is reason enough to go.

During pregnancy and breastfeeding

Ask your doctor before starting any new active at this time. Retinoids (including cosmetic retinol) and hydroquinone are advised against. Melasma and acne are common in pregnancy; your doctor can suggest safe options.

Until you see the doctor

Stop the new product you suspect.
Keep only a gentle cleanser and a fragrance-free moisturizer.
Do not apply lemon, toothpaste, home packs or someone else's cream.
Do not stop prescribed medicine on your own; tell the prescriber.
Note the names or photos of what you applied and when it started.

Questions people ask

Can a photo sent online diagnose my skin?

A photo can give a hint, but light, camera and makeup change a lot. Oliareen's Skin Advisor also only reads patterns; it does not diagnose. See a doctor in person to be sure.
