The depigmentation may be more or less important, and the white spots, […]
The aging of the skin
We would like to continue to look as young as we feel “inside”, but the deadline is inevitable: over time, the skin cells are renewed more slowly (causing a thickening of the epidermis to causes dead cells that accumulate); collagen fibers deteriorate in the dermis; the sebaceous and sweat glands atrophy (reducing hydration); and gravity attracts the soft […]
The vulgar and plantar warts
The warts are small rough protuberances benign, well-defined, which form in the epidermis (the outer layer of the skin). They are usually a few millimeters in diameter but may be larger. They result from an infection caused by a human papillomavirus (HPV) virus and can be contagious. They are most often painless and do not necessarily require treatment. Children and adolescents are the most likely to be affected. […]
