Daily sun protection is one of the most effective ways to support healthy-looking skin and help reduce the visible signs of premature ageing. Even on cloudy days, ultraviolet (UV) radiation can penetrate the atmosphere and reach the skin. Over time, repeated exposure to UV rays can contribute to pigmentation, uneven skin tone, fine lines, wrinkles, and loss of skin elasticity.

There are two primary types of UV radiation that affect the skin. UVA rays penetrate deeper into the skin and are largely responsible for visible skin ageing, while UVB rays primarily affect the outer layers of the skin and are most commonly associated with sunburn. Both forms of UV radiation can contribute to skin damage and should be considered when selecting sun protection.

The skin naturally contains important structural proteins such as collagen and elastin, which help maintain firmness and resilience. Repeated UV exposure generates reactive oxygen species, also known as free radicals, which can break down these proteins and accelerate the ageing process. This process is known as photoageing and can occur gradually over many years.

Applying a broad-spectrum sunscreen daily helps protect the skin from both UVA and UVB rays. Consistent sun protection, together with an appropriate skincare routine, can help maintain a more even complexion and support long-term skin health.
