- More common in women, particularly during pregnancy or the use of oral contraceptives
- Can become a chronic condition
- Lab tests and imaging are not required
In photo-melanosis, hyperpigmentation or dark patches develop on the parts of the skin that are overexposed to the sunâ€™s radiation. The hyperpigmentation is the result of excess melanin in the epidermis, dermis or both. The main reason for many kinds of pigmentations is vitamin D via too much of sun exposure acting as a catalyst in the production of melanin.
The formation of pigmented patches affects the following areas:
- Zygomatic cheeks or the widest part of the cheeks near the cheek-bone
- Upper cutaneous lip
Some therapeutic strategies can be used for curing this condition. Here, the hyperpigmentation is bleached, and the formation of any new pigment is prevented by blocking sun exposure.
The hyperpigmentation can be prevented using sunscreen lotions with a minimum SPF of 30+.
A dermatologist may also suggest the medical combination of hydroquinone, topical retinoid and corticosteroid creams.
Pigmentation in photo-melanosis can be taken care of completely if treated in the early stages. Dermatologist prescribed medication can help in early recovery. At mfine, you can get in touch with the dermatologists from top-notch hospitals within minutes of appointment.
