What is Sunscreen?
Sunscreen, also known as sunblock or sun cream, is a skincare product that helps protect the skin from the harmful effects of ultraviolet (UV) radiation from the sun. It works by either absorbing, reflecting, or scattering UV rays, preventing them from penetrating the skin and causing damage. Regular use of sunscreen helps in reducing the risk of sunburn, premature aging, and skin cancer.

Uses of Sunscreen
Sunscreen serves multiple purposes in skincare and health, including:
1. Protection Against UV Rays β It acts as a shield against UVA and UVB rays, preventing sunburn and long-term skin damage.
2. Prevention of Skin Cancer β Continuous sun exposure can increase the risk of skin cancers, including melanoma. Sunscreen lowers this risk by blocking harmful radiation.
3. Reduces Premature Aging β UV rays contribute to premature aging signs like wrinkles, fine lines, and dark spots. Sunscreen slows down these effects by protecting skin elasticity.
4. Prevents Sunburn β A severe sunburn can lead to pain, peeling, and long-term skin damage. Sunscreen minimizes the risk of burns.
5. Prevents Hyperpigmentation β Dark spots and uneven skin tone caused by sun exposure can be reduced with consistent sunscreen use.
6. Protects Against Tanning β Excessive UV exposure leads to tanning, which is a sign of skin damage. Sunscreen helps in reducing unwanted tanning.
7. Maintains Overall Skin Health β By keeping the skin protected from environmental damage, sunscreen helps in maintaining a youthful and healthy complexion.

Effects of Sunscreen on the Skin
Sunscreen has both positive and negative effects, depending on its type, usage, and individual skin sensitivity.
Positive Effects:
1. Prevents Skin Damage β Reduces inflammation and redness caused by sun exposure.
2. Moisturizes the Skin β Many sunscreens contain hydrating ingredients that help keep the skin soft and nourished.
3. Improves Skin Texture β Prevents roughness, dryness, and uneven skin tone caused by sun exposure.
4. Prevents DNA Damage β Reduces the risk of genetic mutations caused by UV radiation, which can lead to skin cancer.
Negative Effects:
1. Allergic Reactions β Some chemical sunscreens may cause irritation, itching, or rashes, especially on sensitive skin.
2. Acne Breakouts β Oily and heavy sunscreens can clog pores, leading to acne in individuals with oily or acne-prone skin.
3. Eye Irritation β Sunscreen that gets into the eyes can cause discomfort and a burning sensation.
4. Environmental Impact β Certain ingredients like oxybenzone and octinoxate can harm marine life when washed off into the ocean.

Types of Sunscreens
Sunscreens are mainly classified into two types based on their mode of action:
1. Physical (Mineral) Sunscreen:
Contains active ingredients like zinc oxide and titanium dioxide.
Works by sitting on the skin and reflecting UV rays.
Ideal for sensitive skin as it causes less irritation.
Leaves a white cast, especially on darker skin tones.
2. Chemical Sunscreen:
Contains ingredients like oxybenzone, avobenzone, octinoxate, and homosalate.
Absorbs UV radiation and converts it into heat, which is released from the skin.
Lightweight and blends easily into the skin.
May cause allergic reactions in sensitive individuals.
Other Types:
Hybrid Sunscreen β A combination of physical and chemical ingredients for better protection and ease of use.
Water-Resistant Sunscreen β Ideal for swimming or sweating, providing longer protection in water-based activities.
Tinted Sunscreen β Contains pigments to match skin tones, reducing the white cast effect of physical sunscreens.
Matte Sunscreen β Designed for oily skin to reduce shine and greasiness.

How to Apply Sunscreen Correctly
Proper application of sunscreen ensures maximum protection from sun damage. Follow these steps for best results:
1. Choose the Right SPF:
SPF (Sun Protection Factor) indicates how well a sunscreen protects against UVB rays.
SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%.
Higher SPF is recommended for prolonged sun exposure.
2. Apply Generously:
Use about Β½ teaspoon for the face and neck and a shot-glass amount (around 2 tablespoons) for the entire body.
Insufficient application reduces effectiveness.
3. Apply 15β30 Minutes Before Sun Exposure:
Chemical sunscreens need time to absorb into the skin.
Physical sunscreens provide instant protection.
4. Reapply Every 2 Hours:
Sunscreen wears off due to sweating, swimming, and touching the skin.
If swimming or sweating, reapply every 80 minutes or after towel drying.
5. Donβt Forget Key Areas:
Apply sunscreen to often-missed spots like ears, neck, back of hands, feet, and lips.
Use lip balm with SPF for lip protection.
6. Layer Sunscreen with Skincare and Makeup:
Apply sunscreen after moisturizer but before makeup.
Reapply using powder sunscreen or setting sprays with SPF when wearing makeup.
