What Is Pregnancy Melasma?
Pregnancy melasma is a pigment condition. Brown or grey-brown patches appear on the cheeks, forehead, nose and upper lip during pregnancy. The patches often match on both sides of the face.
Doctors diagnose melasma by examining the skin. You need no blood test or scan for the diagnosis.
Melasma is harmless to you and your baby. The patches affect skin colour only. Melasma is common in pregnancy, most of all in medium to deeper skin tones and in sunny climates such as Dubai.
Why Does Pregnancy Trigger Melasma?
- Hormones: Oestrogen, progesterone and melanocyte-stimulating hormone rise in pregnancy. Pigment cells become more active.
- Sun and visible light: Light switches the active pigment cells on
- Heat: Heat stimulates pigment cells, even in the shade
- Family history: Melasma in close relatives raises your chance
- Skin tone: Medium to deeper skin produces pigment more readily
The same hormones darken the line down the abdomen and the skin around the nipples. These changes share one cause.
When Does Pregnancy Melasma Appear and Fade?
| Stage | What to Expect |
|---|---|
| First trimester | Patches are uncommon. Start daily SPF now. |
| Second and third trimester | Patches appear or darken |
| First 3 months after birth | Hormones settle. Many patches start to lighten. |
| Up to 12 months after birth | Fading continues for many women |
| Beyond 12 months | Persistent patches need a treatment plan |
Breastfeeding and hormonal contraception sometimes slow fading. Melasma often returns in later pregnancies.

What Does a Daily Routine Look Like During Pregnancy?
| Time | Step |
|---|---|
| Morning | Gentle cleanser, vitamin C serum, moisturiser, tinted mineral SPF 50 |
| Midday | Reapply sunscreen before going outside |
| Evening | Gentle cleanser, azelaic acid if your doctor approves, moisturiser |

What Should You Avoid During Pregnancy?
| Treatment | Guidance | Reason |
|---|---|---|
| Hydroquinone | Avoid | High absorption through the skin and limited safety data |
| Retinoids, including retinol and tretinoin | Avoid | Oral forms cause birth defects. Doctors avoid topical forms as a precaution. |
| Oral tranexamic acid | Avoid | Not used for melasma in pregnancy |
| Medium and deep chemical peels | Avoid | Absorption and irritation risk |
| Laser and light treatments | Postpone | Limited safety data, and rebound risk while hormones stay high |
| Injectable skin treatments | Postpone | Not tested in pregnancy |
| Bleaching creams bought online | Avoid | Some unregulated products contain steroids or mercury |
What Changes After Birth and During Breastfeeding?
- Give the patches time: Many lighten over 6 to 12 months as hormones settle.
- Keep up sun protection: Light keeps pigment cells active after birth.
- During breastfeeding: Options stay limited. Sunscreen, azelaic acid, vitamin C and niacinamide remain common choices. Your doctor confirms each product.
- After breastfeeding: The full range opens. Options include doctor-prescribed brightening creams, mild peels and low-energy laser.
- Contraception: Hormonal contraception triggers melasma in some women. Discuss options with your doctor.

How Do You Lower the Chance of Pregnancy Melasma?
- Start a tinted mineral SPF 50 in the first trimester.
- Reapply every 2 hours outdoors.
- Wear a wide-brim hat and sunglasses.
- Stay in the shade between 10 am and 4 pm.
- Skip saunas, steam rooms and hot yoga.
- Use gentle, fragrance-free skincare. Irritation leads to more pigment.
- Take care with waxing or threading on the upper lip if your skin reacts easily.
Prevention lowers the severity. Some women develop melasma despite careful protection.
When Should You See a Doctor?
- Patches persist 12 months after birth
- Patches affect your confidence at any stage
- A single dark spot changes in size, shape or colour
- Pigment appears with itching, a rash or other symptoms
