What intervals you need to apply the sunscreen again and why ?

Using sunscreen is vital to protect our skin, but it's not enough to just apply it once a day.

UV rays are constantly damaging your skin, so it's important to reapply periodically. But how often do you really need to do it?

Why is relubrication necessary?

  1. Physical and chemical degradation

    Sunlight, sweat, water and friction gradually reduce the effectiveness of sunscreen, so the level of protection can be significantly weakened after just 2 hours.

  2. Continuous exposure to UV rays

    With every step you take, UV rays continue to arrive. Protection cannot be used as a one-time “resistance”. Continuous means that you have to reapply it about every 2 hours to maintain the sun protection.

  3. Beach, pool, sports

    Sunscreen comes off easily when swimming, sweating, or toweling off. In such cases, it should be reapplied immediately after water or sweating, ideally after drying your hands.

How to use it correctly?

  1. Use enough cream to cover the entire face and neck; 1-2 fingertip amounts (approx. 1 ml) are recommended.

  2. Apply 20 minutes before sun exposure, this is how long it takes for the filters to form.

  3. Repeat every two hours, especially if you are outdoors, bathing, or cleaning yourself.

  4. If you wear makeup, it's a good idea to refresh it with powder or SPF spray around noon after applying sunscreen in the morning.
