Cosmelan
What is Cosmelan?
Cosmelan is a topical treatment used to improve dark spots caused by conditions such as melasma, post-inflammatory hyperpigmentation and pigmentation resulting from aging or sun exposure. It works by regulating the overproduction of skin pigment, with the goal of reducing and eliminating severe dark spots that are difficult to treat.

This treatment consists of two phases in which the doctor and patient work together to achieve optimal results. Cosmelan 1 is an intensive depigmenting mask applied by the physician in the clinic. Cosmelan 2 is used by the patient at home according to the specialist’s instructions, and includes a depigmenting cream, a soothing balm to relieve irritation and a sunscreen with specific photoprotection for this treatment.
What is Cosmelan used for?
The use of Cosmelan helps lighten dark spots by regulating excess pigment production, since it inhibits the enzyme tyrosinase, which is essential in melanin formation. In this way, it helps control and balance skin pigmentation by reducing dark spots with highly effective results.
Dr. Juan Carlos Lloreda, specialist in aesthetic and anti-aging medicine, is recognized in Colombia for treating severe skin pigmentation cases with life-changing results for his patients. Dr. Lloreda notes that this product is part of a comprehensive treatment plan that includes, among other factors, dietary changes, control of emotional triggers, protection from sun exposure and the use of additional skin-improving techniques such as Q-Switch Laser, biostimulators and bioregulatory IV therapy.
Benefits
Cosmelan treatment provides benefits such as a significant reduction of dark spots on the skin, a more even tone, increased luminosity and even a more rejuvenated appearance.
Cosmelan has a dual action of correcting and regulating dark spots, which helps prolong the positive results on the skin. “Today it is possible to treat dark spots from conditions such as melasma, ashy dermatitis or post-inflammatory hyperpigmentation with very good expectations to improve the appearance of the skin and restore patients’ self-esteem,” explains Dr. Juan Carlos Lloreda.
The results of Cosmelan are highly satisfactory, both due to the significant reduction of dark spots and its long-lasting effects. Patients treated by Dr. Juan Carlos Lloreda for conditions such as melasma, ashy dermatitis or post-inflammatory hyperpigmentation report up to 90% improvement, resulting in a stronger sense of self-confidence.
Duration
The two phases of the Cosmelan treatment may take around 6 months, depending on the severity of the condition. The more complex the pigmentation, the longer the treatment requires. Results can be long-lasting, depending on the patient’s discipline and consistency.
Application process
Cosmelan 1 is an intensive mask that must be applied by the doctor in the clinic after creating a personalized treatment plan for each patient. Cosmelan 2 is then applied topically at home and must be used carefully following the specialist’s instructions.
Expectations
The results of Cosmelan are highly satisfactory, both due to the significant reduction of dark spots and its long-lasting effects. Patients treated by Dr. Juan Carlos Lloreda for conditions such as melasma, ashy dermatitis or post-inflammatory hyperpigmentation report up to 90% improvement, resulting in a stronger sense of self-confidence.

Frequently Asked Questions
How does the skin look after Cosmelan?
Cosmelan promotes skin depigmentation, giving a lighter and more even tone and even a natural glow that creates a rejuvenated appearance.
How many times can Cosmelan be used?
The specialist will determine whether a new treatment is appropriate, based on the patient’s previous condition.
How long does it take for a dark spot to fade?
Cosmelan results may be noticeable even after the first session, but they become more evident after two weeks, depending on the patient’s skin tone and the condition of their dark spots. The depigmentation process can take several months with continuous improvement and highly effective outcomes.
What ingredients does Cosmelan contain?
Cosmelan contains a combination of ingredients such as tyrosinase inhibitors, azelaic acid, phytic acid, kojic acid, arbutin and others.
Does Cosmelan cause a rebound effect?
There is no rebound effect. It is important to understand that conditions such as melasma, ashy dermatitis or post-inflammatory hyperpigmentation are chronic, which means they can reappear at any point in life. However, if the treatment is followed according to medical recommendations, together with a healthy lifestyle that includes proper nutrition, emotional management and sun protection, the results can be very long-lasting.
Another reason dark spots may reappear is when the treatment is interrupted or the at-home phase is not completed, which prevents the regulation of melanin production.
Contraindications
Regarding contraindications, it is not suitable for individuals with skin infections, high sensitivity or allergies to its components.
Cosmelan may cause side effects such as skin redness, peeling, tightness or sensitivity, which gradually diminish as the treatment progresses.
Recommendations
Discipline is essential to maintain results by following the at-home treatment and adopting a healthy lifestyle with a strong focus on sun protection.
If the patient does not follow the at-home phase or interrupts it, they cannot expect significant improvement in their skin condition.
It is important to remember that these conditions are chronic, meaning they may reappear at any time. However, with proper care, some patients go years without seeing dark spots return.
Dr. Lloreda makes recommendations such as eliminating or significantly reducing inflammatory foods like dairy, wheat and processed products from the diet, managing emotional stress and avoiding sun exposure.
