Pregnancy-safe skincare in Singapore: ingredients to avoid, treating acne and melasma, and what aesthetic clinics will and won't do

Pregnancy-safe skincare in Singapore starts with what to leave out. Isotretinoin, the acne tablet, can seriously harm an unborn baby, HealthHub's medicine leaflet says, and the retinoid creams tretinoin and adapalene and the lightening cream hydroquinone all carry the same instruction: tell your doctor if you're pregnant. A gentle cleanser, moisturiser and SPF 30 or higher sunscreen are fine, and Thomson Medical's dermatologists say mild acids such as azelaic and lactic acid are generally suitable. For acne, a KKH doctor advises asking a doctor before using medicated gels. Aesthetic clinics generally defer lasers, peels and laser hair removal until after the birth, and HSA has found mercury and banned ingredients in whitening and acne creams sold online, so buy carefully.

Ingredients: avoid, ask first, or fine

When in doubt, take the tube to your pharmacist or doctor. The National Skin Centre's advice for skin problems in pregnancy is to tell your doctor you're pregnant and to avoid self-medicating and traditional remedies, which may affect your baby.

Treating acne while pregnant

Pregnancy hormones can set off acne, HealthHub notes. A KKH doctor's advice is to consult a doctor before using medicated acne gels or lotions, because some over-the-counter ingredients aren't safe in pregnancy or haven't been well studied, and to see a dermatologist for severe acne.

• Wash twice a day with a gentle cleanser and don't scrub.
• Use oil-free moisturiser and sunscreen labelled non-comedogenic.
• Leave spots alone; picking makes marks last longer.
• Ask your doctor about azelaic acid or a prescription gel that suits pregnancy rather than restarting the retinoid you used before.
• Change your pillowcase often in Singapore's humidity, and shower after sweating.

If you were on isotretinoin or a retinoid when you found out you're pregnant, stop it and tell your doctor. HealthHub's isotretinoin leaflet says to stop immediately; your doctor can talk you through what it means for your pregnancy.

Dark patches (melasma) and other pigmentation

Many women get darker patches on the cheeks, forehead and upper lip, called melasma, and darker nipples, moles and a line down the tummy. SingHealth says melasma may improve after delivery but rarely fully clears, and that treatments such as hydroquinone, TriLuma, chemical peels and lasers are recommended only after delivery. Thomson Medical's dermatologists add that options are limited in pregnancy, so consistent sun protection and gentle skincare are the best approach, and that waxing can irritate skin and make melasma worse.

• Wear SPF 30 or higher every day, reapply when outdoors, and add a hat; Singapore's sun is strong all year.
• Skip waxing on the face, and use gentle hair-removal methods.
• Don't buy whitening creams online to fix it fast; see the HSA warnings below.

What aesthetic clinics will and won't do while you're pregnant

Tell any clinic or salon you're pregnant before treatment, and ask what's in the products they use. If a clinic offers a treatment the table says to defer, ask the doctor why, and check with your obstetrician.

Buying skincare safely in Singapore

Cosmetics don't need HSA approval before they're sold, and HSA has issued several alerts about creams sold in shops and online for whitening and acne that contained undeclared mercury, hydroquinone or tretinoin. HSA says hydroquinone and tretinoin are prohibited in cosmetics and should only be used under strict medical supervision, and that mercury creams can cause rashes and skin discolouration, and with long-term use damage the kidneys, digestive and nervous systems.

• Be wary of products promising quick whitening or miracle results; HSA says these may contain potent ingredients.
• Buy from reputable pharmacies and shops with full ingredient labels.
• Treat "approved by HSA" on a cosmetic as a red flag; HSA doesn't approve cosmetics.
• Stop any product that causes a reaction, and see a doctor if it doesn't settle.

Frequently asked questions

What skincare should I avoid when pregnant?

Isotretinoin, retinoids such as tretinoin, adapalene and retinol, and hydroquinone. HealthHub's leaflets say to tell your doctor if you're pregnant, and isotretinoin can seriously harm an unborn baby.

Is azelaic acid safe during pregnancy?

Generally, yes. Thomson Medical's dermatologists say mild acids such as azelaic and lactic acid are generally suitable in pregnancy.

Can I use salicylic acid while pregnant?

Low-strength products are usually fine. Thomson Medical lists salicylic acid among over-the-counter options, and the American Academy of Dermatology says to use strengths above 2% sparingly.

Can I do laser or chemical peels while pregnant?

Wait until after the birth. SingHealth says melasma treatments such as peels and lasers are recommended only after delivery, and Thomson Medical defers laser hair removal.

Is Botox safe in pregnancy?

We found no Singapore guidance on Botox or fillers in pregnancy, and most clinics defer them. HSA requires injectables to be registered and given by qualified doctors.

How do I treat acne while pregnant?

Gentle cleansing, oil-free products and sunscreen, and ask a doctor before medicated gels, as a KKH doctor advises. See a dermatologist for severe acne.
