This article deciphers the latest scientific data: mechanisms, skincare routine, lifestyle, but also peels, microneedling and laser. For product selection, BeautyDecoded algorithmic scores and feedback from the app's users are used to objectify each analysis.<\/p>\n      <div class=\"bd-callout\">This content is for information and educational purposes only. It does not constitute medical advice, and recommendations must be adapted to each individual. The application <strong>BeautyDecoded<\/strong> analyzes INCI formulations using artificial intelligence to identify the right cosmetics for each skin type.<\/div>\n    <\/div>\n  <\/section>\n\n  <!-- ============ COMPRENDRE ============ -->\n  <section class=\"bd-section\">\n    <div class=\"bd-wrap-narrow\">\n      <div class=\"bd-section-label\">The fundamentals<\/div>\n      <h2>Understanding <em>melasma<\/em>.<\/h2>\n      <p class=\"bd-prose\">Melasma results from a disorder of the melanocytes, which begin to produce melanin in large quantities in specific areas: the forehead, cheekbones and upper lip. It mainly affects women.<\/p>\n      <p class=\"bd-prose\">Triggering factors include sun exposure, pregnancy or hormonal imbalance, skin inflammation linked to diet or poor cosmetics, and genetic predisposition. Its treatment is complex: all the more reason to rely on science rather than marketing superlatives.<\/p>\n      <p class=\"bd-prose\">A major breakthrough comes from a study published in 2019: contrary to what was previously thought, melasma is not just a disorder of melanocytes. <strong>It also involves keratinocytes, mast cells, skin inflammation and alteration of the basement membrane.<\/strong> <a class=\"bd-source\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/30403434\/\" target=\"_blank\" rel=\"noopener\">(Kwon SH et al., 2019)<\/a>. It is by acting on all these mechanisms that we can hope to overcome them.<\/p>\n    <\/div>\n  <\/section>\n\n  <!-- ============ CINQ M\u00c9CANISMES ============ -->\n  <section class=\"bd-section\">\n    <div class=\"bd-wrap\">\n      <div class=\"bd-section-label\">The strategy<\/div>\n      <h2>Fight melasma: <em>five mechanisms to target<\/em>.<\/h2>\n      <p class=\"bd-prose\">To maximize the effectiveness of anti-stain treatments, five mechanisms must be considered simultaneously.<\/p>\n      <div class=\"bd-mechs\">\n        <div class=\"bd-mech\"><div class=\"bd-mech-num\">01<\/div><h4>The basal membrane<\/h4><p>Do not break the skin. A laser or peel that is too powerful will cause inflammation and rupture of this membrane, making melasma worse. Rushing is counterproductive.<\/p><\/div>\n        <div class=\"bd-mech\"><div class=\"bd-mech-num\">02<\/div><h4>Tyrosinase<\/h4><p>Reduce the action of the enzyme that converts tyrosine into melanin. This is the pathway by which an increase in estrogen aggravates melasma. Several active ingredients target this enzyme.<\/p><\/div>\n        <div class=\"bd-mech\"><div class=\"bd-mech-num\">03<\/div><h4>Keratinocytes<\/h4><p>Limit keratinocyte irritation: niacinamide slows melanin transfer to these cells.<\/p><\/div>\n        <div class=\"bd-mech\"><div class=\"bd-mech-num\">04<\/div><h4>Inflammation<\/h4><p>Chronic inflammation - sun, diet, irritating cosmetics - aggravates melasma. The challenge is to act without irritating.<\/p><\/div>\n        <div class=\"bd-mech\"><div class=\"bd-mech-num\">05<\/div><h4>Mast cells<\/h4><p>Sun exposure increases the number of mast cells, a major cause of hyperpigmentation. One active ingredient stands out here: tranexamic acid.<\/p><\/div>\n      <\/div>\n      <p class=\"bd-prose\" style=\"margin-top: 24px;\">So there's no simple treatment that can knock out melasma: what's needed is a real change of habits. And the most effective measure is sun protection, because UV rays and visible light are the source of all these mechanisms.<\/p>\n    <\/div>\n  <\/section>\n\n  <!-- ============ PROTECTION SOLAIRE ============ -->\n  <section class=\"bd-section\">\n    <div class=\"bd-wrap-narrow\">\n      <div class=\"bd-section-label\">Measure no. 1<\/div>\n      <h2>Sun protection : <em>the most effective measure<\/em>.<\/h2>\n      <p class=\"bd-prose\">Sun protection, yes, but not just any kind. Choose mineral sunscreens with zinc oxide, which protect against UVB and UVA rays. Tinted sunscreens are also recommended: they often contain iron oxides, which protect against the visible light emitted by the screens. Failing that, a BB cream containing iron oxides will do the trick, as more and more studies are establishing a link between visible light and melasma.<\/p>\n      <p class=\"bd-prose\">Another subtlety: some sunscreens are irritants, notably avobenzone and octocrylene. Irritation should be avoided in cases of melasma. Read the list of ingredients carefully, and observe your skin's reaction to each new product.<\/p>\n      <div class=\"bd-tip\">\n        <span class=\"bd-tip-label\">Key point<\/span>\n        <p>Your melanocytes have become \u00absuper melanocytes\u00bb. A very short exposure is enough to reactivate them. Sun protection must therefore be <strong>daily<\/strong>, cover visible light, and be renewed every two hours outdoors.<\/p>\n      <\/div>\n    <\/div>\n  <\/section>\n\n  <!-- ============ INGR\u00c9DIENTS ============ -->\n  <section class=\"bd-section\">\n    <div class=\"bd-wrap-narrow\">\n      <div class=\"bd-section-label\">Assets<\/div>\n      <h2>The ingredients <em>effective against melasma<\/em>.<\/h2>\n      <p class=\"bd-prose\">The active ingredients that regulate tyrosinase are hydroquinone, azelaic acid, glycolic acid and retinoids. Each has a corresponding level of scientific evidence, from 1 (maximum proven efficacy) to 5 (mere expert opinion without study).<\/p>\n      <div class=\"bd-actives\">\n        <div class=\"bd-active\"><h4>Hydroquinone<\/h4><p>Prescribed by the dermatologist as a magistral preparation combining several depigmenting agents. Not to be used over a long period, as it may cause serious side effects.<\/p><\/div>\n        <div class=\"bd-active\"><h4>Azelaic acid<\/h4><p>Reduces the action of tyrosinase. Derived from cereals (barley, wheat, rye), of synthetic origin in cosmetics. Also highly effective against acne and redness.<\/p><\/div>\n        <div class=\"bd-active\"><h4>Glycolic acid<\/h4><p>Diminishes the action of tyrosinase and is a useful complement to an anti-melasma routine, provided it is gentle enough not to irritate.<\/p><\/div>\n        <div class=\"bd-active\"><h4>Tranexamic acid<\/h4><p>Acts on both tyrosinase and the mast cells responsible for neovascularization. A 2019 study showed it to be as effective as topical hydroquinone, without its side effects <a class=\"bd-source\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/30022486\/\" target=\"_blank\" rel=\"noopener\">(Kim SJ et al., 2019)<\/a>.<\/p><\/div>\n        <div class=\"bd-active\"><h4>Niacinamide<\/h4><p>Reduces melanin transfer to keratinocytes.<\/p><\/div>\n        <div class=\"bd-active\"><h4>Vitamin C<\/h4><p>Reduces free-radical inflammation, mitigates the effects of the sun and regulates melanocytes. Oral intake may even be beneficial.<\/p><\/div>\n      <\/div>\n      <p class=\"bd-prose\" style=\"margin-top: 24px;\"><strong>Retinoids<\/strong> are highly effective: they shorten the cell regeneration cycle and regulate tyrosinase. The mistake to avoid would be to buy all these active ingredients at once and launch a complex routine: the skin won't tolerate it.

Three main treatments are used: peels, microneedling and lasers. They accompany the preceding measures, but are not a miracle solution.<\/p>\n      <p class=\"bd-prose\">Peelings and lasers are best avoided in summer, with several sessions scheduled for winter. Peels should be gentle; glycolic acid, widely studied in melasma, can be combined with azelaic acid or kojic acid. Microneedling creates microchannels that facilitate the penetration of active ingredients. Non-abrasive lasers are preferred to avoid pigmentary rebound, and the procedure must be performed by a physician after skin preparation. <strong>Use extreme caution on dark skin.<\/strong><\/p>\n      <p class=\"bd-prose\">In 2016, a Beverly Hills team proposed a three-phase treatment algorithm:<\/p>\n      <div class=\"bd-phases\">\n        <div class=\"bd-phase\"><span class=\"bd-phase-tag\">Phase 1<\/span><p>Sun protection and combination of topical active ingredients.<\/p><\/div>\n        <div class=\"bd-phase\"><span class=\"bd-phase-tag\">Phase 2 - if unsuccessful<\/span><p>Addition of superficial peels and non-abrasive lasers.<\/p><\/div>\n        <div class=\"bd-phase\"><span class=\"bd-phase-tag\">Phase 3 - new failure<\/span><p>Additional treatments: radiofrequency, Q-switch laser, IPL, microneedling.<\/p><\/div>\n      <\/div>\n      <div class=\"bd-tip\" style=\"margin-top: 26px;\">\n        <span class=\"bd-tip-label\">The main pitfall<\/span>\n        <p>Visit <strong>relapse<\/strong> Melasma fades in winter and returns in spring.

Topical active ingredients and sun protection always come first; non-abrasive lasers are only an adjunct.<\/div>\n        <\/details>\n        <details class=\"bd-faq-item\">\n          <summary>Which asset should you choose to start with?<\/summary>\n          <div class=\"bd-faq-answer\">Tranexamic acid combined with niacinamide is an excellent gateway: it targets a key melasma mechanism and is very well tolerated. Vitamin C and retinoids are then added gradually, once the skin has become accustomed to them.<\/div>\n        <\/details>\n        <details class=\"bd-faq-item\">\n          <summary>Why do we need protection against visible light?<\/summary>\n          <div class=\"bd-faq-answer\">Because more and more studies are linking visible light to melasma.
