PIKIRAN RAKYAT - Sunscreen is a universal product, a summer staple found in beach bags and backpacks everywhere. Its primary function is to protect us from the sun's harmful rays, which is undeniable. But sunscreen's impact goes beyond a simple block. Let's delve into how sunscreen affects us, including its benefits and potential drawbacks.
Sunlight exposure provides essential vitamin D, which is crucial for bone health and immune function. However, overexposure to ultraviolet (UV) radiation from the sun can lead to sunburns, premature skin aging, and even skin cancer. Sunscreen acts as a shield that absorbs or reflects UV rays, mitigating these damaging effects.
Positive Impacts of Sunscreen
1. Reduced Skin Cancer Risk
Skin cancer is the most common form of cancer in the United States, with one in five Americans expected to develop it in their lifetime. Studies consistently show that regular sunscreen use significantly reduces the risk of all types of skin cancer, including melanoma, the deadliest form.

According to the American Academy of Dermatology, daily sunscreen use with an SPF 15 or higher can reduce your risk of developing squamous cell carcinoma by 55% and melanoma by 33%.
2. Prevents Premature Skin Aging
Sun exposure significantly contributes to wrinkles, fine lines, and uneven skin tone. UV rays break down collagen and elastin, the fibers that give skin its structure and elasticity. Sunscreen helps preserve these fibers, keeping skin youthful and healthy for longer.
3. Protects People with Photosensitivity
Certain medications and medical conditions can make people hypersensitive to sunlight. Photosensitivity can cause severe sunburn or blistering reactions with minimal sun exposure. Sunscreen becomes crucial for these individuals, allowing them to participate in outdoor activities with minimal risk.
