Vitiligo: can new treatments really repigment the skin?

Vitiligo: can new treatments really repigment the skin?

Vitiligo, an autoimmune disease affecting 1-2% of the population, appears as patches of depigmentation. Long considered to have 'no solution', it is now experiencing a therapeutic revolution: ruxolitinib (Opzelura), the first specific anti-JAK treatment, enables melanocytes to recolonise the skin, with on average 75% repigmentation of the face in one in two patients. But application is demanding, results are slow (6 to 24 months) and the treatment is reserved for less extensive forms. Vitiligo is neither contagious nor psychosomatic: several options exist (immunomodulators, cortisone, UVB phototherapy, melanocyte autograft), and early management is decisive.

Cosmetic "dupes": bargains or real risks for your skin?

Cosmetic "dupes": bargains or real risks for your skin?

Popularised on social media, "dupes" are cosmetics presented as cheaper alternatives to major brands. Not all are counterfeits, but outside regulated channels some may have a non-compliant composition, contaminants (heavy metals, phthalates), incorrect labelling or no European representative. Sunscreens are the most concerning case: SPF 50+ claims with no effective UV filter. Advice: buy from pharmacies/official distributors, check the INCI, be wary of abnormally low prices. Sources: Regulation (EC) 1223/2009, BEUC, FEBEA.

Red hair: does pheomelanin hide an unsuspected protective role?

Red hair: does pheomelanin hide an unsuspected protective role?

Why does red hair exist if its pigment, pheomelanin, offers less protection against UV and a higher skin-cancer risk? In an animal model, its production could serve to eliminate excess cysteine, an amino acid that is toxic when it accumulates. Pheomelanin could thus fulfil an ancient biological function, independent of pigmentation.
