Dangers of Sun Exposure & How to Protect Your Skin
What is Sunlight?
Sunlight consists of different types of radiation and light, categorized by wavelength:
1. Visible Light (45%)

๐ Can cause skin darkening and worsen pigmentation over time
2. Invisible Light (Ultraviolet - UV)
UV radiation is divided into:
๐ UVA - causes skin aging, wrinkles, and pigmentation
๐ UVB - causes sunburn and increases the risk of skin cancer
๐ UVC - mostly blocked by the atmosphere
3. Infrared Light (50%)
๐ Produces heat
๐ Infrared A contributes to premature aging (photoaging)
๐ Damages collagen and causes wrinkles through free radical formation
How Dangerous are UVA & UVB?
๐ UVA - Premature aging, dark spots, wrinkles
๐ UVB - Sunburn and increased risk of skin cancer
How to Protect Yourself from Sunlight

2. Physical Sunscreen

๐ Protects against UVA, UVB, visible light, and infrared
๐ Less irritating, suitable for sensitive skin
How to Choose Sunscreen for Your Skin Type
๐ Oily / Combination Skin: Gel, lotion, or oil-free formulas
๐ Normal Skin: Any type is suitable
๐ Dry Skin: Cream-based with moisturizing ingredients
๐ Sensitive Skin: Alcohol-free
