What Is Sunscreen?
Sunscreen is a skincare product designed to protect the skin from harmful ultraviolet (UV) rays emitted by the sun. It works by either absorbing or reflecting UV radiation to reduce skin damage. Sunscreens come in different forms such as creams, gels, sprays, and lotions.
There are two main types of UV rays that affect the skin:
- UVA: Causes premature aging, wrinkles, and pigmentation.
- UVB: Responsible for sunburn and skin surface damage.
Benefits of Sunscreen
1. Prevents Sunburn
Sunscreen helps protect the skin from redness, irritation, and painful sunburn caused by excessive sun exposure.
2. Reduces Premature Aging
Regular sunscreen use helps reduce:
- Fine lines
- Wrinkles
- Dark spots
- Skin sagging
It protects collagen and elastin fibers from UV damage.
3. Lowers the Risk of Skin Cancer
Long-term UV exposure may increase the risk of skin cancer, and sunscreen is considered an important preventive measure.
4. Helps Prevent Hyperpigmentation
Daily sunscreen use can reduce melasma, dark spots, and uneven skin tone, especially in sensitive skin types.
What Does SPF Mean?
SPF stands for “Sun Protection Factor,” which measures protection against UVB rays.
Common SPF levels include:
- SPF 15: Moderate protection
- SPF 30: Good protection
- SPF 50+: High protection
Higher SPF numbers provide stronger protection, but no sunscreen blocks 100% of UV rays.
Difference Between UVA and UVB
| Type | Skin Effect |
|---|---|
| UVA | Causes aging and pigmentation |
| UVB | Causes sunburn |
| Broad Spectrum | Protects against both UVA and UVB |
Experts recommend choosing a “Broad Spectrum” sunscreen for complete protection.
