Hi ! Dark spots and dark undereye circles are two different entities . I would suggest that you consult a dermatologist in person so that they will be able to assess the pigmentation which will enable him/her to formulate a treatment plan specific for your needs. Your dermatologist will then suggest either a cream or a procedure which will help in bringing down the pigmentation and improve the skin texture and tone.
Start by using a doctor prescribed sunscreen with an SPF of atleast 30 .The sunscreen should be applied once in 3 hours especially between 7am-5pm,the first application should ideally be used 20 minutes before you step out into the sun.
Do not use over the counter 'skin lightening' creams that a pharmacist / friend suggests . It can cause more harm than good . I hope this answers your query !
Thanks for the query. This is a common condition and is an urban life style related problem. The dark circle around the eyes at your age is unusual and could indicate an insulin resistance. Skin is the mirror of internal health and to get a perfect skin you need to treat both ways - internally and externally. See a Dermatologist who will recommend a product for reducing puffiness and darkness and will advocate the correct method to use it. Avoid rubbing the eyes as it will increase pigmentation. Your Dermatologist may request a few blood tests to understand the blood chemistry and treat them specifically. Now-a-days many chemical peels also offers realistic promise- like glycolic acid and lactic acid peels. Dermapen in combination with mesotherapy also helps.
A good skin care regimen comprises 4 steps - cleansing, toning, moisturizing and sunblock. Based on your skin type, a dermatologist will recommend you appropriate products.
