How to remove melasma spots?

Also referred to as "chloasma", the melasma is due to a disruption in the pigmentation process (melanogenesis). The melanin, pigment responsible for the natural colouration of the skin, is overproduced in certain areas, leading to the appearance of brown spots. These spots most often appear on the face.

According to the American Academy of Dermatology, only 10% of melasma cases affect men.

Women with darker skin types and/or who are pregnant are more likely to develop melasma. Indeed, this type of skin disorder is due to hormonal fluctuations.The increase in oestrogen levels, particularly during pregnancy or with the use of certain medications (e.g. the pill), can lead to brown spots. These are exacerbated by exposure to the sun's UV rays, hence the importance of proper protection with a sun care product suited to one's skin tone.

pregnancy mask". It often disappears spontaneously after childbirth.

There are different types of melasma depending on the layer of the skin presenting the brown spots:

• The epidermal melasma: Brown spots only affect the superficial surface of the epidermis;

• The dermal melasma: The spots form at the deep layer of the skin, known as the dermis;

• The mixed melasma: Hyperpigmentation spots appear on both the superficial and deep layers of the skin.

Depending on the location of the brown spots, there are also 3 other types of melasma:

• The centrofacial melasma: The spots are clustered in the T-zone, upper lip, and chin area;

• The Malar Melasma: The spots are located solely on the nose and cheeks;

• The mandibular melasma: Aggregation of spots on the lower jaw.

To lighten brown spots in a less invasive and gentler manner than aesthetic medicine, certain treatments contain lightening active ingredients. At Typology, we have developed various formulations to reduce the appearance of melasma:

• Enriched with active ingredients to balance the skin's pH, brighten the complexion, and reduce the appearance of pigmentation spots, the radiance toner with vitamin C also contains lemon verbena water for a subtle fruity scent. Following the makeup removal steps, this toning lotion is applied with a cotton pad across the entire face, avoiding the eye contour, and does not need to be rinsed off.

• The pigmentation spot serum with arbutin acid and lemon extract helps to reduce brown spots and delay their appearance. Often referred to as natural hydroquinone due to its pigment-regulating nature, the remarkable effectiveness of alpha-arbutin against brown spots is due to its perfect affinity with the active site of tyrosinase, an enzyme involved in the formation of melanin. Thus, this competitive inhibition of the enzyme's active site blocks its activity and consequently the synthesis of melanin. Moreover, derived from the pressed fruit, the lemon extract (INCI: "Citrus Limon (Lemon) Fruit Water") is recognised for its toning and unifying properties. We recommend using this serum daily, morning and evening, for a minimum period of 6 weeks in order to observe its effects.

• The radiance facial serum is highly concentrated in Vitamin C (11%) and provides a real boost to dull and tired complexions. This treatment also contains 3% of Albizia Julibrissin extract (INCI: "Albizia Julibrissin Bark Extract"). This combination helps to reduce pigmentation spots and slow down the photo-ageing of the skin. We recommend using this serum daily, morning and evening, for a minimum period of 4 weeks in order to observe its effects.

• The hyperpigmentation and firmness loss serum contains a high concentration of tranexamic acid (5%). A synthetic derivative of lysine, it limits the synthesis of melanin by blocking the interaction between skin cells and melanocytes. However, when applied topically only, the tranexamic acid acts on epidermal type melasmas. It thus presents itself today as a new safe alternative to hydroquinone. This care also contains tetrapeptide-2, a peptide composed of four amino acids that stimulate the synthesis of key molecules involved in the support and firmness of the skin: elastin, collagen and fibrillin.
