Stretch marks (striae gravidarum) are very common in pregnancy. They usually appear on the abdomen, breasts, hips and thighs as the skin stretches quickly, often in the second half of pregnancy. They are harmless, though many people would prefer to limit them.

Why they form

Stretch marks happen when the deeper layer of the skin, the dermis, is stretched faster than it can adapt, and the collagen and elastic fibres are disrupted. Genetics plays a large part: if close family members had them, you are more likely to. Rapid weight gain and younger age at pregnancy are also linked with them.

New stretch marks are often red, pink or purple. Over months to years they fade to paler, silvery lines.

Creams and oils: what to expect

Many creams are sold to prevent stretch marks. Research has not shown that any product reliably prevents them. Some studies suggest that products containing ingredients such as hyaluronic acid or Centella asiatica may help a little, and massaging a moisturiser into the skin daily keeps it comfortable and may reduce itching.

If you use a product, start early in pregnancy, apply it regularly, and see it as skin care rather than a guaranteed prevention.

Ingredients to check while pregnant or breastfeeding

Avoid retinoids (such as tretinoin and retinol) during pregnancy. Ask a doctor or pharmacist about any product with strong active ingredients, and check that skin products sold in Thailand are notified with the Thai Food and Drug Administration. Stop using anything that causes a rash or irritation.

Treatments after birth

Once you have finished breastfeeding, a dermatologist can offer treatments that may improve the colour and texture of stretch marks. Options include topical retinoids, vascular lasers for red marks, fractional lasers, microneedling and radiofrequency devices. Results vary, and most treatments need several sessions. Newer, red marks tend to respond better than older, pale ones.

Products made for pregnancy

Some Thai brands make creams specifically for use during pregnancy. Read the ingredient list and discuss it with your doctor or midwife, especially if you have sensitive skin or a skin condition.
