Bioderma Photoderm Kid SPF 50+ is a very high photoprotection spray that stimulates the self-defence systems of children's fragile skin. In addition to its surface UVA/UVB protective activity (filtering systems), it offers real internal biological protection: cellular bioprotection. This exclusive patent preserves and stimulates the skin's defenses (immunity) during sun exposure. This patent has been specially combined with C-peptide, a derivative of 3 natural amino acids (methionine, arginine, glycine), which strengthens protection against DNA damage caused by UVB rays, which are particularly harmful for the thin, fragile skin of children.
