This is a high-protection sunscreen with SPF 30 that shields skin from both UVA and UVB rays — meaning it helps protect you from sunburn (UVB damage) and long-term skin damage like premature aging (UVA damage) Apply generously before sun exposure and reapply every two hours or after swimming, sweating, or towelling for best protection. Even with sunscreen, avoid prolonged sun exposure and take additional sun-safe measures.
