Second trimester (weeks 13–27) — beauty treatment safety

Light alpha-hydroxy acid peels — glycolic, lactic and mandelic — are the peels with a long safety record in pregnancy, and lactic acid peels are sometimes prescribed for pregnancy acne. That record is for lower strengths, up to about 30%, so ask for a gentler concentration than you would normally have and tell your therapist you are pregnant. Pregnancy hormones also spike the risk of melasma, which makes reactive skin worth taking seriously.

TCA, phenol and Jessner's peels penetrate deeply and have documented systemic absorption — a measurable amount reaches your bloodstream. Salicylic acid at peel strength is in the same drug class as aspirin, which is contraindicated in pregnancy at therapeutic doses.

Laser and IPL on the face are avoided during pregnancy for two reasons. Pregnancy hormones already trigger melasma in many women, and light energy can deepen that pigmentation unpredictably. And systemic safety data is absent — there are no human trials, because no one runs them on pregnant women. Pregnancy melasma is best managed with sun protection and gentle camouflage for now, and treated after pregnancy.

Enzyme peels are the one peel the guidance places squarely in the safe column during pregnancy and while you are breastfeeding. If you want some resurfacing in your facial, this is the one to ask for.

Every one of these devices — HIFU, radiofrequency, CoolSculpting, EMSculpt, ultrasonic cavitation — lists pregnancy as an absolute contraindication in its own manufacturer instructions. The energy reaches deep tissues, and no safety data exists for exposure during pregnancy. The contraindications here are explicit and universal.

No controlled human safety data exists — trials in pregnancy are ethically impossible, so the studies that would answer this question will never be run. Manufacturers' prescribing information and all major bodies, including the NHS, ACOG and the EMA, advise against elective cosmetic injectables in pregnancy. Most aesthetic clinics in the UK will decline to treat you regardless.

Laser and IPL on the face are avoided during pregnancy for two reasons. Pregnancy hormones already trigger melasma in many women, and light energy can deepen that pigmentation unpredictably. And systemic safety data is absent — there are no human trials, because no one runs them on pregnant women. Pregnancy melasma is best managed with sun protection and gentle camouflage for now, and treated after pregnancy.

Prenatal massage is actively recommended from the second trimester onwards for stress, swelling, back and hip pain, and sleep quality. What makes it safe is the training and the positioning: your therapist should be certified in pregnancy massage and should work with you side-lying or semi-reclined, never flat on your back after week 20, because of vena cava compression. A general massage therapist without prenatal training should refer you to a colleague who has it.

Waxing, sugaring and threading remove hair mechanically. Nothing enters your bloodstream and nothing affects your baby, so they are safe throughout pregnancy and while you are breastfeeding. The one consideration is skin sensitivity: pregnancy hormones can leave your skin more sensitive, redder and easier to bruise, so tell your therapist you are pregnant. A Brazilian wax in the third trimester is awkward positionally, but not medically contraindicated.

Manicures and pedicures are safe throughout pregnancy and while breastfeeding, gel included — UV/LED nail lamp exposure is tiny and localised to your hands or feet. Two things are worth getting right. Ask for good ventilation, because fumes from acrylic products and standard polish are the real concern. And choose a '3-free' or '10-free' polish, which leaves out formaldehyde, dibutyl phthalate (DBP), toluene and camphor. Pedicures are particularly welcome in the third trimester, when reaching your own feet becomes difficult.
