What is Chloasma (Pregnancy Mask)?

Symmetrical pigmentation caused by hormonal changes from pregnancy or oral contraceptives

Estrogen and progesterone stimulate melanocytes, causing brown patches on the cheeks and forehead. They may resolve naturally after childbirth.

Main causes & characteristics of Chloasma (Pregnancy Mask)

Fluctuations in estrogen and progesterone — such as those occurring during pregnancy or with use of oral contraceptives — are known to stimulate melanocytes and increase pigment production as the primary mechanism. When UV exposure is added on top of this, the result is darkening of symmetrically distributed brown patches on the cheeks and forehead. After delivery, as hormones stabilize, the patches are known to fade naturally in some cases.

Managing Chloasma (Pregnancy Mask)

Since UV exposure may intensify pigmentation, applying a broad-spectrum sunscreen generously every day is considered the most fundamental step. Ingredients such as vitamin C and niacinamide are known to help with achieving a more even skin tone. If pigmentation spreads or persists for a long time, consulting a dermatologist to establish an appropriate management plan is recommended.

Everyday care tips

Reducing direct sun exposure to the face with a wide-brimmed hat or parasol, and applying sunscreen before going outdoors and reapplying at midday, may help.
