Sunlight & Skin: Balancing Vitamin D Benefits with UV Damage Risks

Sunlight gives us life—and vitamin D—but it can also accelerate skin aging and increase the risk of skin cancer. So how do you find the sweet spot between benefit and damage?

The Good: Sunlight as a Natural Vitamin D Source

• Sun exposure helps the body produce vitamin D, which is essential for bone health, immunity, and mood.
• Just 10–20 minutes of sunlight (without SPF) on face, arms, or legs, a few times per week, can be enough—depending on skin tone, latitude, and time of year.

The Bad: Cumulative UV Damage

• UVB rays cause burns and DNA damage
• UVA rays penetrate deeper, causing wrinkles, sagging, and pigmentation
• Chronic exposure increases risk of melanoma and other skin cancers

How to Stay Safe While Reaping the Benefits

• Get morning sunlight before 10 a.m. for gentle UVB exposure
• Use SPF 30+ after initial unprotected exposure (10–15 min max)
• Wear wide-brimmed hats and UV-blocking clothing outdoors
• Consider vitamin D supplements during winter or in low-sun climates

Your skin and your health both matter—smart sun habits let you protect one while supporting the other.
