The Year-Round UV Threat

Many people associate sun damage with beach days and summer holidays. But UV rays reach your skin every day of the year — even through clouds, even in winter, even through windows.

UVA vs UVB

  • UVB: Causes sunburn, peaks in summer, varies by season
  • UVA: Penetrates deep into the dermis, present all year, passes through clouds and glass

UVA is the primary driver of premature ageing — it breaks down collagen and elastin, causing wrinkles, sagging, and pigmentation.

Fact: Up to 80% of UV rays penetrate cloud cover. Winter sun exposure still causes cumulative damage.

Signs of Sun Damage

  • Uneven skin tone and dark spots
  • Fine lines and wrinkles (especially around eyes and mouth)
  • Broken capillaries
  • Rough, leathery texture
  • Loss of skin elasticity
  • Solar lentigines (age spots)

Prevention Is Year-Round

Daily SPF 50+

Apply every morning, 365 days a year. Choose a broad-spectrum formula that protects against both UVA and UVB.

Reapplication

Every two hours when outdoors. For daily indoor wear, once in the morning is typically sufficient.

Protective Habits

  • Wear UPF clothing and wide-brimmed hats
  • Seek shade during peak hours (10am–4pm)
  • Be extra careful near water, snow, and sand (UV reflects)

Reversing Existing Damage

Professional treatments can significantly improve sun-damaged skin:

  • Chemical peels: Remove pigmented, damaged layers
  • Laser pigmentation reduction: Target and shatter dark spots
  • Microneedling: Stimulate fresh collagen to replace damaged tissue
  • Vitamin C infusions: Deliver antioxidants directly into the skin

Start Now

It's never too late to start protecting your skin. Daily sunscreen prevents 90% of preventable ageing, and professional treatments can reverse much of the damage already done.
