La Shield Fisico SPF 50+ PA+++ Matte Sunscreen Gel is a broad-spectrum sunscreen that helps protect your skin from both UVA and UVB rays, which can cause sunburn, premature skin ageing, and sun-related skin damage. It contains zinc oxide, a physical sunscreen ingredient that forms a protective barrier on the skin and is suitable for many people with sensitive skin. The lightweight gel has a matte, non-greasy finish, making it comfortable for daily use and suitable for most skin types, including oily skin. It is also water-resistant, which helps maintain protection during sweating or outdoor activities. Apply it generously to all exposed skin about 15 to 20 minutes before going outdoors, and reapply every 2 hours or more often after swimming or excessive sweating. Using sunscreen daily, along with protective clothing and avoiding intense midday sunlight, provides the best defence against harmful sun exposure.

For a dark upper lip, use a physical sunscreen with zinc oxide to protect the skin from sunlight and prevent further darkening. Hydroquinone can help lighten the area, but should be used only after a doctor's advice, as it may irritate. Eating fruits, vegetables, and nuts, and staying hydrated, helps improve overall skin health.
