Sunscreen products protect the skin from harmful UV rays, reducing the risk of premature aging, spotting and skin cancer. It should be applied 15-20 minutes before going out in the sun and should be renewed every 2 hours, especially after sweating or swimming. The SPF (Sun Protection Factor) value indicates the product’s level of protection against UVB rays. At least SPF 30 is recommended for daily use. It is also important to choose according to skin type; mattifying sunscreens for oily skin and moisturizing sunscreens for dry skin should be preferred. Broad spectrum products provide both UVA and UVB protection. Sunscreens should be used regularly throughout the year, not just in summer, because UV rays are also effective in cloudy weather. Also, special formulas for children and sensitive skin should be preferred. Sunscreens that can be applied under make-up can also be easily integrated into the daily care routine. Using these products without neglecting them is critical for long-term skin health.
