Sun protection is one of the most important steps in any skincare routine. Ultraviolet (UV) radiation causes premature ageing, wrinkles, and a higher risk of skin cancer, so shielding your skin every day is essential. Sunscreen forms a protective barrier that reduces how much UV reaches your skin.

UVA vs UVB Rays

Both UVA and UVB rays damage the skin, but in different ways.

Layers of the skin: epidermis, dermis, and hypodermis

UVA Rays (Aging)

UVA rays penetrate deep into the dermis and break down collagen and elastin, the fibres that keep skin firm. Over time this leads to wrinkles, fine lines, and age spots, often appearing years after exposure.

UVB Rays (Burning)

UVB rays affect the outer epidermis, causing sunburn and reddening. They are more directly linked to the DNA damage that raises skin cancer risk.

How Sunscreen Protects Your Skin

The SPF number measures protection against UVB rays by indicating how much longer skin can be exposed before burning. A higher SPF improves UVB defence but does not penetrate deeper into the skin. For full coverage, choose a broad-spectrum sunblock that guards against both UVA and UVB.

Types of Sunscreen

Physical (Mineral) Sunscreen

Contains zinc oxide or titanium dioxide that sit on the skin's surface and reflect UV rays. A good choice for sensitive skin, including tinted formulas that double as light coverage.

Chemical Sunscreen

Uses organic filters that absorb UV rays and release them as heat. These tend to feel lighter and blend in easily, with options up to SPF 50 for daily wear.

Broad-Spectrum and Water-Resistant

Broad-spectrum formulas cover both UVA and UVB, while water-resistant versions stay effective through swimming or sweating and should be reapplied regularly.

Why Everyone Should Wear Sunscreen

Whatever your skin type, daily sunscreen prevents sunburn and premature ageing, supports healthy skin, and minimises dark spots and pigmentation caused by the sun. It is a simple investment in long-term skin health.
