Melasma: understand the causes and how to treat the spots for good

Melasma is one of the most common concerns in an aesthetic dermatology clinic: brownish patches, usually symmetrical, that appear on the forehead, cheeks, upper lip or chin. It is a frequent condition, especially in women, and known for being persistent — but that doesn't mean it can't be treated.

What is melasma?

Melasma is a hyperpigmentation caused by excessive melanin production in specific areas of the skin, resulting in brownish patches that tend to be symmetrical on both sides of the face. It can vary in depth — epidermal, dermal or mixed — which directly influences the choice of treatment protocol.

What causes melasma?

Melasma has a multifactorial origin, and is usually the result of a combination of more than one cause:

  • Genetic predisposition — a family history of melasma increases the chance of developing it.
  • Hormonal changes — pregnancy, use of birth control pills and hormone replacement are common triggers.
  • Sun exposure — ultraviolet light and visible light stimulate melanin production in the affected areas.
  • Skin predisposition — skin richer in melanin tends to have a higher tendency toward melasma.

Why is melasma difficult to treat?

Melasma is known for being a resistant, recurring condition: the melanocytes (melanin-producing cells) in these areas become hyperactive, and any new stimulus — such as unprotected sun exposure — can reactivate pigment production, even after a successful treatment. That's why the right protocol combines lightening techniques with strict, ongoing sun protection.

The Skims Melani protocol

Skims Melani is the SKIMS Method's exclusive protocol for melasma and dark spots, with the choice of peel and lightening actives personalized according to the depth and type of melasma identified in the assessment — the goal is to act on excessive melanin production and reorganize the skin's pigmentation progressively and safely.

Maintenance: the path to a lasting result

Treating melasma "for good" means, in practice, consistently controlling the condition over time — the initial protocol visibly improves the spots, but maintaining the result depends on ongoing follow-up and daily protection habits. It is this combined care that prevents relapse and keeps the skin even in the long run.

Essential daily care

  • Broad-spectrum sunscreen, reapplied throughout the day, even indoors.
  • Use of hats, caps and sunglasses during longer sun exposure.
  • Avoiding direct sun exposure during peak UV hours.
  • Following the actives and follow-up visits routine recommended by the professional, without stopping on your own.
