About this treatment

Cosmelan is the medical depigmenting treatment with the strongest scientific backing worldwide. It works by inhibiting the tyrosinase enzyme over a prolonged period to reduce melanin production at its source, effectively treating melasma, sun spots, post-inflammatory hyperpigmentation (acne marks) and uneven skin tone. Dr. Téllez applies the full protocol in the office with personalized follow-up throughout the treatment phase.

FAQ

Frequently asked questions

Does Cosmelan work for melasma?+

Yes. Cosmelan is one of the treatments with the most scientific evidence for melasma. It works by inhibiting tyrosinase, the enzyme responsible for melanin production, reducing existing spots and preventing them from coming back. Results are progressive and visible from the first week.

How long does it take to see results?+

The first results in radiance and spot reduction are seen from the first week. Maximum improvement is seen between 4 and 8 weeks of treatment. Subsequent maintenance consolidates and prolongs the result.

Is the process painful, or is there a long recovery?+

The procedure is not painful. During the first days after application there may be redness, sensitivity and mild to moderate peeling, lasting 3 to 7 days. After that the skin settles and treatment continues with the maintenance cream at home.

Do dark spots come back after Cosmelan?+

Without maintenance and sun protection, melasma can come back because it has a hormonal and genetic component. Dr. Téllez designs a personalized maintenance protocol to prolong the results and prevent spots from reappearing.
