Hello. Thanks for writing to us at healthcaremagic
Regarding the transverse nasal crease, it is an idiopathic and treatment is usually ineffective. Cosmetics can be used to make it less prominent Or cover it up.
Your main concern is Pigmentation/dark spots, which can be a problem in skin of color.
Sunscreen is an essential part in the management of Pigmentation. I would suggest that you use a broad spectrum sunscreen throughout the day.
It should have both UV A as well as UV B coverage. Reapply every 2-3 hours.
A broad spectrum sunscreen that has a minimum spf of 30 or more, would be suitable.
At night you may use a cream, containing one or more of the following active ingredients e.g
Tretinoin,
Mometasone, Azaleic acid,
Hydroquinone,
Kojic acid, Arbutin,
Glycolic acid, licorice extract, Niacinamide, Vit C etc.
Along with the creams, you may also opt for a few sessions of chemical peeling from your
dermatologist.
Pigmentation may recur if sun protection is not strict and therefore sun screen is to be used even after the pigmentation resolves.
Pigmentation may take time to respond and you have to be patient with the treatment and follow up regularly with a dermatologist.
Your dermatologist might change or modify treatment according to the response.
