Organic screening agents lose efficacy and chemical stability upon prolonged exposure to ultraviolet radiation. Preventing this degradation ensures consistent photoprotection and prevents the formation of harmful byproducts.

Active sunscreen ingredients often lose efficacy or produce harmful radicals upon exposure to sunlight. Preventing this breakdown ensures prolonged skin protection and formula stability.

Human skin undergoes cellular degradation and premature aging when exposed to solar radiation. Preventing this damage maintains biological integrity and prevents long-term pathological conditions.
