The sun's ultraviolet (UV) rays can cause skin damage, such as premature aging , sun spots , loss of elasticity , and, in the worst cases, skin cancer . Sunscreen acts as a barrier between the skin and UV rays, reducing the risk of skin damage and keeping skin young and healthy .

Sun protection factor (SPF) indicates how effective a sunscreen is at blocking UVB rays, which are responsible for sunburn and short-term skin damage. A higher SPF offers greater protection from UVB rays. However, it is important to choose a product with broad-spectrum protection, which also protects against UVA rays, which are responsible for skin aging and long-term damage.

• Fair Skin: If you have fair skin and tend to burn easily, opt for a high SPF (at least 30) to ensure adequate protection.

  
  

• Olive or medium skin: If you have olive or medium skin and don’t burn easily, an SPF of 15-30 may be sufficient for adequate protection.

  
  

• Dark Skin: Although dark skin has natural protection from UV rays, it is still important to use an SPF of at least 15 to ensure full protection.

• Physical (mineral): Physical sunscreens, such as titanium dioxide and zinc oxide, reflect UV rays away from the skin's surface. They are ideal for sensitive skin and those who prefer natural products. However, they may leave a slight white residue on the skin.

  
  

• Chemical (organic): Chemical sunscreens, such as avobenzone and octyl oxalate, absorb UV rays and convert them into heat, which is then released by the skin. They are generally lighter and more invisible on the skin, but can cause irritation in some people.

• Apply sunscreen every day , even when it is cloudy or in winter, as UV rays can pass through clouds and reflect off snow.

• Use an adequate amount of sunscreen: for the face and neck, it is advisable to use at least an amount the size of a 2 euro coin .

• Remember to apply sunscreen to all exposed areas , including your neck, ears, and hands.

• Apply sunscreen 15-30 minutes before sun exposure to allow the product to fully absorb into the skin.

• Repeat application every two hours , or more often if you are swimming or sweating a lot.
