What does the UVA star rating mean on sunscreen?

The UVA star rating on sunscreen indicates how effective the product is at protecting your skin from UVA rays, which can cause long-term skin damage and ageing. The rating ranges from zero to five stars, with more stars signifying better protection. This system helps consumers choose sunscreens that offer adequate UVA protection alongside UVB protection.

Key points:

• The UVA star rating measures protection against UVA rays.
• A higher star rating means better skin protection.
• UVA rays contribute to skin ageing and damage.
• It's important to use products with both UVA and UVB protection.
