The Neusc formula, with its combination of UVA/UVB filters, protects the skin from the harmful effects of the sun by adding a physical-chemical filter to the skin's surface. It forms a barrier that protects against dehydration and redness caused by solar radiation. It is especially recommended for dull skin with very high radiation, for fair skin with high or very high radiation, and for very fair skin with medium or high radiation. Directions for use: External use. Gently glide on in a single stroke and spread over the entire area with your fingertips until completely absorbed. Apply 15 minutes before sun exposure and reapply every 2 hours.
