Understanding Sun Damage
Sun damage happens when rays from the sun—or artificial sources like tanning beds—penetrate the skin and harm its cells.
Even short bursts of unprotected sun exposure add up over the years. The results can include:
- Fine lines and wrinkles
- Uneven skin tone or hyperpigmentation
- Redness or broken capillaries
- Rough, dry, or leathery texture
- Increased risk of skin cancers like melanoma
Even if you don’t see changes yet, sun damage can be present below the surface—and early detection helps prevent visible signs.

Types of Light
UVA Light
- Wavelength: 320–400 nm
- Damage:
- Breaks down collagen and elastin → wrinkles, sagging
- Triggers uneven pigmentation and age spots
- Can damage skin cells’ DNA, increasing cancer risk
UVB Light
- Wavelength: 280–320 nm
- Damage:
- Causes sunburn
- Directly damages DNA in skin cells
- Plays a major role in skin cancer development
Visible Light
- Wavelength: 400–700 nm
- Damage:
- Blue-violet light (especially from the sun, not just screens) may contribute to hyperpigmentation in sensitive skin
- Some high-intensity visible light sources (like certain lasers) can trigger inflammation or pigment changes
Infrared (IR) Light
- Wavelength: 700 nm–1 mm
- Damage:
- Produces heat, which can break down collagen and elastin
- Can contribute to redness, inflammation, and aging over time
Prevention is Beautiful
Your skin’s best defense is a mix of daily protection and smart habits:
- Apply broad-spectrum SPF 30+ every day (rain or shine).
- Reapply every 2 hours if outdoors.
- Wear hats, sunglasses, and protective clothing.
- Seek shade between 10 a.m. – 4 p.m.
- Pair sunscreen with antioxidant-rich skincare for extra defense.
Treating Sun Damage
While prevention is key, professional treatments can help reverse visible effects:
- Brightening facials & chemical peels
- Laser or light therapy
- Microneedling
- Targeted skincare with Vitamin C, niacinamide, or retinoids
