Sun damage and photoageing

Sun damage is caused by ultraviolet (UV) radiation from the sun, including UVA, UVB, visible light and infrared-A. It is these rays that lead to sunburn, DNA damage, premature skin ageing and an increased risk of skin cancer.

Photoageing describes the accelerated ageing process of the skin, due to repeated and unprotected sun exposure. This results in fine lines and wrinkles, loss of elasticity, uneven skin tone and hyperpigmentation.

What causes sun damage?

  • UVA

    UVA rays are present all year round, penetrating deep into the skin and causing premature skin ageing and an increased risk of skin cancer.

  • UVB

    UVB rays are strongest in the summer months, causing the redness, blisters and pain of sunburn, as well as increasing the risk of cancer.

  • Visible Light

    Visible light, which is emitted from the sun but also includes blue light from digital devices, increases oxidative stress in the skin.

  • Infrared-A

    Infrared-A penetrates even deeper than UV radiation, causing damage to the skin’s structure.

Who is at risk?

Every person, no matter their skin type, is at risk of sun damage. High risk factors include those with fair skin that burns easily, very young or old skin, people living close to the equator or at high altitude, where the ozone layer is low, and those who work outside and are regularly exposed to the sun’s rays. Not using sun protection is also a high risk factor for sun damage and photoageing.

Sun protection is the most important step in your daily skincare routine, because no matter the weather, sunlight radiation is present and harmful all year round. The best way to protect the skin from sun damage and photoageing is to apply a high-level, broad-spectrum SPF, every single day.
