Sunscreen :
Skin spots caused by prolonged exposure to the sun appear mainly on the hands. To protect them, use a sunscreen enriched with zinc, applying it every morning and throughout the day if you wash your hands often.
Biotin :
A 2500 mcg dose of this supplement can help us have stronger nails. Biotin increases the production of keratin, which is essential for nails and hair.
Consult a doctor before taking any supplement.
