The importance of sun protection and proper use

Sunscreen is an essential step in daily skincare and protecting skin health. It effectively prevents damage from ultraviolet (UV) radiation and reduces various sun-related issues. Below, I will provide a detailed description of the importance of sunscreen and the correct usage methods:

1. Skin cancer prevention:
Long-term exposure to UV radiation increases the risk of skin cancer. Using sunscreen reduces the damage caused by UV radiation to skin cells and decreases the chances of developing skin cancer.

2. Prevention of sunspots and hyperpigmentation:
UV radiation is the main cause of sunspots, freckles, and hyperpigmentation. Sunscreen effectively reduces the production of melanin triggered by UV exposure, preventing the occurrence and worsening of these issues.

3. Prevention of skin aging:
UV radiation is one of the primary factors contributing to skin aging. Prolonged exposure to UV rays leads to skin sagging, increased wrinkles, and decreased elasticity. Proper use of sunscreen can slow down the skin aging process, helping to maintain a youthful and healthy complexion.

4. Protection of the skin barrier:
UV radiation damages the skin's barrier function, making it more susceptible to external irritants and damage. Sunscreen forms a protective layer, reducing the harmful effects of external factors on the skin and helping to maintain its overall health.

Correct usage methods:

1. Choose the right sunscreen:
When selecting sunscreen, pay attention to the sun protection factor (SPF) and UVA protection index. The higher the SPF, the better the sun protection. It is recommended to choose a product with an SPF of 30 or higher. Additionally, ensure the product offers broad-spectrum protection to shield the skin from both UVA and UVB rays.

2. Apply an adequate amount:
Apply sunscreen to exposed skin 15-30 minutes before going outside. Ensure even application, not forgetting areas such as the face, neck, ears, and arms that are prone to UV exposure.

3. Reapply as needed:
The protective effect of sunscreen is not permanent and needs regular reapplication. It is generally advised to reapply every 2 hours or immediately after sweating or swimming. Even on cloudy days or when indoors for extended periods exposed to computer or phone screens, sunscreen should still be used.

4. Combine with other sun protection measures:
Sunscreen is just one part of sun protection. Other measures such as wearing UV-protective hats, sunglasses, and using umbrellas are also recommended. Try to avoid prolonged exposure to the sun during peak hours (10 am to 4 pm).
