Glutathion : l’actif star qu’on adore détester (mais qui change tout !)

Glutathione: the star active ingredient we love to hate (but which changes everything!)

Marc Antoine

Glutathione, what is it?

Glutathione is a molecule naturally produced by our bodies. Present in almost all our cells, it plays a key role: protecting against free radicals, repairing cellular damage, and regulating melanin production. In other words, it's a star antioxidant that acts as a true shield for the skin.

The stereotypes that circulate

For years, glutathione has had a controversial reputation:

  • ❌ “It’s dangerous for your health”

  • ❌ “It artificially whitens the skin”

  • ❌ “It’s reserved for injections”

In reality, these preconceived ideas come from misuse (e.g. unregulated injections in certain countries) and misleading marketing.

Scientific truth

✔️ Glutathione does not discolor the skin: it works by regulating excessive melanin production, which helps reduce dark spots and even out skin tone.
✔️ Used in topical cosmetics (cream, serum), it is safe and acts gradually, respecting the skin.
✔️ In addition to unifying, it protects the skin against premature aging and oxidative stress.

Why it is so valuable in an anti-blemish routine

Hyperpigmentation (spots, quintos, irregularities) is a recurring problem for black and dark skin. Glutathione works on two fronts:

  • It limits the appearance of new spots by regulating melanin.

  • It boosts natural radiance by revealing more even skin.

The Manibel Anti-Stain Hand Duo: the concrete example

At Manibel, we have incorporated glutathione into our Anti-Dark Spot Hand Duo , as it is one of the most effective active ingredients for targeting quintos, spots and dark areas.
Combined with other powerful active ingredients (such as retinol, aloe vera or niacinamide), it works gradually but visibly to provide softer, brighter and more harmonious hands.

Conclusion

Glutathione is not an instant miracle product, nor is it dangerous: it is a valuable ally, scientifically validated, which acts in synergy with other active ingredients to reveal the radiance of your skin.
Adopted into a regular routine, it becomes one of the best partners for saying bye-bye to stains and regaining confidence.

👉 That's why it's at the heart of our Manibel Anti-Dark Spot Duo : a simple, effective and safe way to pamper your hands every evening.

Pourquoi tes mains méritent autant d’amour que ton visage

Why your hands deserve as much love as your face

We forget them... but they don't forget you! Creams, serums, masks... we pamper our faces, but our hands? They work all day, face water, the cold, household products... and they take it without saying a word. The result: dryness, fine lines, spots. Not glamorous at all. Spoiler: Hands age faster than the face Yes, it's proven. The skin on our hands is thin, fragile, and constantly exposed. And unlike our faces, we rarely think about protecting them with sunscreen (even though they take the full brunt of UV rays 👀). For melanin skin, it's double trouble Small dark areas around the knuckles, uneven skin tone, quintos... in short, our black, olive, and mixed-race hands have their own challenges. And if you want your hands to match your facial glow, you need to give them a real rescue plan. 3 simple gestures for great hands 💕 Moisturize after each wash (your hydroalcoholic gel, it dries everything 👋🏾). Protect them from the sun with SPF cream (yes, even in winter). Take care of them at night : it's while you sleep that your care makes the difference. Manibel: the story begins with the hands At Manibel, it all started there: we decided to give hands the place they deserve in skincare. Our Anti-Dark Spot Hand Duo was designed to unify, nourish, and enhance your hands, so they reflect all the confidence and beauty you already possess. Morality? Don't let your hands be the forgotten ones in your routine anymore. They deserve your love, your SPF... and a little Manibel ✨

The trap of immediate results In the skincare world, many expect visible results within days. This phenomenon is even more pronounced among black and dark-skinned women, who often face hyperpigmentation issues (spots, blemishes, irregularities) that take time to fade. The result: we change products too quickly, we stop our routine... and we deprive ourselves of the real benefits. The Science Behind Patience The skin renews itself on average every 28 days . 👉 For a pigment spot, you have to wait several renewal cycles before it fades. 👉 Active ingredients like turmeric, vitamin C, niacinamide or glutathione are not magic wands: they work gradually , in depth. Speaking comparison: You don't lose 5 kilos after just one workout. You don't make your hair grow 10 cm overnight. Skin works the same way: consistency = lasting results. Why Consistency Changes Everything The active ingredients act in synergy → The results add up day after day. The skin adapts → It regains its balance and becomes more resistant. Regularity prevents relapses → Stopping too soon can cause spots or imperfections to return. Example with a Manibel routine From 3–4 weeks: the complexion begins to appear more even. After 2–3 months: spots visibly fade, skin gains radiance and comfort. With consistency + sun protection: the results become stable and long-lasting. Inspiring Conclusion Consistency is not a constraint, it's a gift you give to your skin . Each application is a proof of love towards yourself. So instead of looking for an immediate miracle, choose regularity: it alone reveals true transformation. 👉 And that's exactly what Manibel routines offer: treatments formulated for melanin-prone skin, which reveal its natural radiance provided you give it the time it deserves.

Bye-bye quintos : la vérité sur ces taches et le soin qui change tout

Bye-bye quintos: the truth about these spots and the treatment that changes everything

What are quintos? For many Black and mixed-race women, it's not uncommon to see dark areas appear on their hands, particularly around the knuckles. These spots, called quintos , are actually a form of localized hyperpigmentation. They can make the hands appear out of sync with the rest of their skin tone, creating a sometimes distracting contrast. Why do they appear? Quintos result from several combined factors: 🌞 The sun : without protection, UV rays stimulate excessive melanin production. ✋ Repeated friction : frequent hand washing, use of household products, pressure on joints. ❌ Lack of hydration : dry skin is more fragile and marks more. 🔄 Genetics and hormones : some skin is simply more prone to it. Daily tips to prevent and alleviate quintos Even if quintos don't disappear overnight, a suitable routine can make a real difference: Moisturize your hands every day Use a nourishing cream after each wash to prevent dryness that accentuates stains. Protect them from the sun Yes, even hands need SPF50 sunscreen, summer and winter. Hand rashes worsen with UV rays. Avoid harsh products Wear gloves when using household products or washing dishes. This reduces friction and exposure to irritants. Gently exfoliates A gentle exfoliation once a week helps remove dead cells and even out the skin. Take care of your consistency As with the face, results require consistency. The skin needs at least 3 to 4 weeks to renew itself. The Manibel Anti-Stain Hand Duo: a targeted solution At Manibel, we have developed the Anti-Dark Spot Hand Duo , specially designed for dark and matte skin prone to quintos. A unifying serum that acts deep down on spots and irregularities. A unifying moisturizer that nourishes, repairs and protects the skin. 💡 Used every night, this duo works gradually to reduce puffiness and restore a uniform, luminous appearance to hands. Combined with good sun protection during the day, the results become visible and long-lasting. In conclusion Quinos are not inevitable. With the right actions and appropriate care, it is entirely possible to regain soft, nourished, and even hands. The important thing is to combine consistency, protection, and targeted care . 👉 Your skin deserves the best. Start your routine today with the Manibel Anti-Dark Spot Duo , and say goodbye to quintos.
