Pigmentation is one of the most stubborn skin concerns to treat. It resists standard peels, returns with sun exposure and, in the case of melasma, can be made worse by the wrong approach. If you have been managing pigmentation with creams, peels or laser with limited success, the Cosmelan depigmentation treatment is the intervention that works when others have not. At Eve Clinics it is performed by Dr Matt George, our plastic surgery trained cosmetic doctor.

What Is the Cosmelan Peel?
Cosmelan is a professional depigmentation system developed by Mesoestetic, one of the world’s leading medical aesthetic laboratories. It is widely considered the most effective non-laser treatment available for hyperpigmentation and is one of the only treatments proven effective across all skin tones, including darker Fitzpatrick types that are often excluded from or put at risk by other pigmentation treatments.
Unlike a standard chemical peel, Cosmelan works at two levels simultaneously. The in-clinic mask delivers an immediate corrective effect by exfoliating the surface and visibly reducing existing pigmentation. At the same time, the active ingredient complex works at a cellular level to regulate melanin production, reducing the chance of that pigmentation returning.
This dual action is what separates Cosmelan from most other approaches. Standard peels and laser treatments can lighten existing dark marks but they do not address the overactive melanocytes that caused those marks in the first place. Without that regulatory element, pigmentation returns. The at-home maintenance phase of Cosmelan targets this directly over a period of months, training the melanocytes to produce pigment in a more controlled and uniform way.
What Types of Pigmentation Does Cosmelan Treat?
Cosmelan is suitable for all forms of hyperpigmentation, including some of the most treatment-resistant. It is formulated without hydroquinone, making it a safe choice for patients who prefer to avoid that ingredient or who have had sensitivities to it in other products.
| Pigmentation Type | What It Is | Common Triggers | Cosmelan Suitability |
|---|---|---|---|
| Melasma | Brown or grey-brown patches, typically on the cheeks, forehead and upper lip. Often symmetrical. | Hormonal changes: pregnancy, the contraceptive pill, HRT, perimenopause | Excellent. One of the most effective treatments for melasma, including hormone-induced cases resistant to other approaches. |
| Chloasma | The pregnancy-specific form of melasma. Sometimes called the mask of pregnancy. | Hormonal changes during pregnancy | Excellent. Treatment is deferred until after delivery and breastfeeding has ended. |
| Post-inflammatory hyperpigmentation | Dark marks left after skin inflammation. Common after acne, injury or certain treatments. | Acne, eczema, burns, chemical peels, laser procedures | Excellent. Particularly effective for darker skin tones where post-inflammatory pigmentation is more pronounced and persistent. |
| Sun spots (solar lentigos) | Flat, well-defined brown spots caused by cumulative UV exposure. Also called age spots. | Years of UV exposure, typically on face, hands and décolletage | Very good. Cosmelan visibly reduces and regulates sun-related pigmentation. |
| Freckles (ephelides) | Small flat light brown spots on fairer skin. More visible in summer. | Genetic predisposition, UV exposure | Good. Cosmelan can significantly reduce freckle intensity, particularly with consistent maintenance. |
| Uneven skin tone | General lack of colour uniformity without distinct spots. Often described as dullness or blotchiness. | Sun damage, ageing, lifestyle factors | Good. Cosmelan improves overall luminosity and evenness alongside targeted pigmentation. |
Why Melasma Is Notoriously Difficult to TreatMelasma is a chronic condition, not a fixed mark. The melanocytes responsible for it remain hyperactive until they are regulated. Without a treatment that addresses this regulatory component, pigmentation returns, often within months. This is why the at-home maintenance phase of Cosmelan is not optional. The in-clinic mask removes the existing pigmentation. The Cosmelan 2 cream, used consistently at home for months afterwards, retrains the melanocytes. Both phases are essential for lasting results.
How Cosmelan Works
The fundamental driver of hyperpigmentation is an enzyme called tyrosinase. This enzyme controls the first step in melanin production. When melanocytes are stimulated by UV exposure, hormones, heat or inflammation, they increase their tyrosinase activity, leading to the overproduction of melanin and the formation of dark marks.
Cosmelan works primarily by inhibiting tyrosinase activity. When this enzyme is suppressed, melanocytes cannot overproduce melanin regardless of the external stimulus. Over time, with consistent use of the maintenance products, melanocyte behaviour normalises and the tendency to produce excess pigment is significantly reduced.
The active ingredient complex works across several pathways at the same time:
- Azelaic acid — inhibits tyrosinase and reduces melanocyte proliferation. Also provides anti-inflammatory benefit, which is particularly relevant in post-inflammatory pigmentation
- Kojic acid — a powerful tyrosinase inhibitor derived from fungal fermentation. Widely studied and clinically proven for depigmentation
- Phytic acid — inhibits melanin synthesis and provides antioxidant protection, reducing oxidative triggers of melanocyte activation
- Ascorbic acid (vitamin C) — interferes with melanin formation at multiple stages and provides antioxidant protection against UV-induced melanin production
- Retinoids — accelerate cell turnover to speed the removal of pigmented cells from the surface and enhance penetration of the other actives
- Arbutin — a naturally derived tyrosinase inhibitor with a gentle safety profile, particularly useful in sensitive skin types
Acting on several points in the melanin production process simultaneously is what makes Cosmelan effective where single-ingredient treatments have not been.
The Treatment Process
Cosmelan requires a week of genuine social downtime and a committed at-home maintenance routine lasting several months. Patients who follow the protocol properly achieve outstanding results. The protocol must be followed.
Step 1 — Consultation and Skin Assessment
Dr George assesses the type, depth and distribution of your pigmentation, determines your Fitzpatrick skin type, reviews your medical history and confirms that Cosmelan is the right approach for you. If you are on hormonal contraception, HRT or other medications that may affect melanin production, this is discussed at consultation and factors into the treatment plan.
Certain preparations are required before the mask. Stop using retinoids and glycolic acid products one week beforehand and avoid waxing or depilatory treatments on the face within two weeks of treatment.
Step 2 — In-Clinic Mask Application
The skin is cleansed and a degreasing solution is applied to improve ingredient penetration. Dr George then applies the Cosmelan 1 mask, a concentrated paste containing the full active ingredient complex at its highest concentration. The mask dries on the skin in clinic and you leave wearing it.
The mask must remain on the skin for between 8 and 12 hours depending on your Fitzpatrick type, skin sensitivity and the severity of your pigmentation. Dr George will give you a precise removal time based on your individual assessment. The mask is removed at home using warm water only.
Step 3 — The Recovery Week
Most patients experience significant redness, warmth and tightness in the first 24 hours, similar to moderate sunburn. From days two to five, the skin begins to peel, sometimes dramatically. This is the old, pigmented surface skin being shed and fresh skin being revealed underneath.
Do not pick or pull the peeling skin. Doing so risks post-inflammatory pigmentation forming in the disturbed tissue. The prescribed soothing balm and SPF should be applied consistently throughout the day. Most patients are not socially presentable during the first five to seven days. Plan accordingly and do not schedule this treatment close to important events or holidays.
Step 4 — At-Home Maintenance with Cosmelan 2
From day seven, the Cosmelan 2 maintenance cream is introduced. This is the regulatory phase and it is not optional. Cosmelan 2 contains the same tyrosinase-inhibiting ingredients at lower concentrations for daily use. It continues to suppress melanocyte overactivity and prevent the return of pigmentation.
The application schedule is intensive at first: three times daily in month one, twice daily in months two and three, once daily in the evening from month four onwards. This commitment is what separates patients who maintain their results long-term from those who see the pigmentation return within months. SPF 50 must be worn every morning without exception throughout the maintenance phase and beyond.
Recovery Timeline
| Timeframe | What to Expect | What to Do |
|---|---|---|
| Mask on (8 to 12 hours) | Skin feels warm and tight. Mild tingling normal. | Avoid touching the mask. Keep to the removal time given by Dr George. |
| Day 1 (removal day) | Significant redness, warmth and tightness. Skin may look bronzed or flushed. | Remove with warm water only. Apply prescribed recovery balm generously. Avoid heat. |
| Days 2 to 5 | Skin begins to peel, sometimes extensively. Itching common. Not socially presentable for most patients. | Do not pick or pull peeling skin. Apply balm frequently. Wear SPF if going outdoors. |
| Days 6 to 7 | Peeling subsiding. Fresh skin revealed. Redness reducing. Pigmentation beginning to visibly fade. | Continue recovery balm. Begin to reintroduce gentle moisturiser if comfortable. |
| Week 2 | Significant improvement in skin tone already visible. Mild residual sensitivity possible. | Introduce Cosmelan 2 from day 7 as directed. SPF 50 every morning without exception. |
| Month 1 | Continued improvement in pigmentation. Skin tone more even. Texture improved. | Cosmelan 2 three times daily. SPF 50 daily. Avoid retinoids and glycolic acid unless directed by Dr George. |
| Months 2 to 3 | Further pigmentation reduction. Results increasingly stable. | Cosmelan 2 twice daily. Strict SPF use continues. |
| Month 4 onwards | Maintenance phase. Results sustained. Melanin production more regulated. | Cosmelan 2 once daily in the evening. SPF 50 every morning. Review with Dr George as needed. |
Honest ExpectationsCosmelan produces long-lasting results when the maintenance protocol is followed correctly and SPF 50 is used consistently. The treatment regulates melanocyte behaviour rather than simply removing surface pigmentation, which is why its results are more durable than standard peels. However, the triggers for hyperpigmentation — UV exposure, hormonal changes and heat — remain present. Without ongoing protection and maintenance, particularly for melasma patients, there is a possibility of gradual return over time. Six-monthly maintenance treatments are available for patients who want to sustain their results.
Is Cosmelan Safe for Darker Skin Tones?
Yes. This is one of Cosmelan’s most clinically significant advantages. The treatment is validated for use across all Fitzpatrick skin types I to VI, including the medium to dark skin tones that carry the highest risk from laser-based depigmentation approaches.
In patients with Fitzpatrick IV to VI skin, post-inflammatory hyperpigmentation is a significant concern with ablative laser treatments. Because these skin tones have higher melanin density and more reactive melanocytes, the inflammation triggered by aggressive treatments can stimulate more melanin production rather than less. Cosmelan’s regulatory approach avoids this. Rather than creating inflammatory trauma, it works by suppressing tyrosinase activity, which is safe and effective regardless of melanin content.
Dr George adjusts the mask application time and maintenance protocol based on your Fitzpatrick type. Darker skin tones typically use a shorter mask time and a more gradual introduction of the Cosmelan 2 cream to avoid unnecessary irritation while still achieving the full regulatory effect.

Frequently Asked Questions
Most patients see visible improvement within the first two weeks as the post-peel skin is revealed and pigmentation begins to fade. Significant results are typically apparent by four to six weeks. The full benefit, including the regulatory effect on melanocyte behaviour, develops over three to six months of consistent use of the Cosmelan 2 maintenance cream.
Cosmelan produces long-lasting results when the maintenance protocol is followed and consistent SPF 50 use is maintained. The treatment regulates melanocyte behaviour rather than simply removing surface pigmentation, which is why its results are more durable than standard peels. Without ongoing protection and maintenance, particularly for melasma patients, there is a possibility of gradual return over time.
Plan for a minimum of seven full days of social downtime. The first five to seven days involve significant peeling, redness and skin sensitivity that most patients would not want to be seen professionally or socially. By day seven to ten the skin has largely settled and can be covered with makeup comfortably.
Yes, but this is important to disclose at consultation. Hormonal medications are a primary trigger for melasma in many patients. If you remain on a hormonal contraceptive or HRT throughout treatment, the hormonal stimulus for melanocyte overactivity is still present and may limit the long-term durability of your results. Dr George will discuss this and factor it into the treatment plan.
Cosmelan can be used in patients with sensitive skin, though the mask application time and maintenance product introduction may be adjusted to minimise irritation. Patients with active eczema or psoriasis on the face, very sensitised skin or a history of significant reaction to cosmeceutical products should discuss this in detail with Dr George at consultation.
For some patients, Cosmelan is used as part of a broader skin management plan alongside CO2 laser resurfacing for textural concerns or biostimulators for hydration. However, Cosmelan should not be combined with other active treatments at the same time. A waiting period is required before and after certain procedures. Do not combine Cosmelan with retinoids, glycolic acid products or laser treatments without specific direction
The Cosmelan peel is performed at Eve Clinics in Leamington Spa, serving patients from across Warwickshire, Coventry, Kenilworth, Warwick, Solihull, Birmingham and Stratford-upon-Avon.
