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

Fluctuations in estrogen and progesterone during pregnancy or from oral contraceptive use are thought to stimulate melanocytes and increase pigment production, which is recognized as the primary mechanism. When combined with ultraviolet exposure, this is known to cause symmetrical brown patches to darken on the cheeks and forehead. After childbirth, when hormone levels stabilize, the patches may naturally fade in some cases.

How to manage

Since ultraviolet light can intensify pigmentation, applying a broad-spectrum sunscreen thoroughly every day is considered the most fundamental step and is recommended. Ingredients such as vitamin C and niacinamide are known to help promote a more even skin tone. If pigmentation spreads or persists for an extended period, consulting a dermatologist to determine an appropriate management approach is recommended.

Good to know alongside

Associated topics include melasma, melanin, melanocytes, hormonal changes, photoaging, and hyperpigmentation. It is commonly discussed as a pigmentation concern in which both UV exposure and hormonal factors act together.

Everyday care tips

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