As an introduction, SPF is an acronym for sun protection factor. It is a vital feature in skin products as deemed by scientists. Only in the past century have we discovered the dangers of direct sunlight, with its ultraviolet (UV) radiation causing a concerning increase skin-related illnesses and complications worldwide.

Such as:

  2. Severe sunburn

  4. Immune suppression
  5. Heat stroke

Other disorders caused by excessive exposure to UV rays include:

  2. Macular degeneration

We must not underestimate UV rays and should take safety precautions to protect ourselves against them.

As we go along, the numbers indicated beside SPF (e.g. SPF 15) should be paid attention to when buying skin-related products. The number is the estimated time taken for the UV rays to penetrate and redden your skin. This estimation is calculated against the time it would take your skin to redden without any protection. In simple terms, UV rays could affect your skin in a single moment without any protection. With a sunscreen SPF 15, UV rays would take 15 times longer to fully affect your skin. The higher the number is, the smaller amount of UV rays it allows to penetrate through.

With this, we resonate that applying sunscreen is vital before leaving the house, especially in the summer. Manufacturers understand that importance thus include SPF in various products.

When under the sun, avoid exposing your chest area, forearms and vulnerable areas to direct sunlight. This makes clothes a feasible weapon against UV ray penetration. On top of that, try to stay in the shade during hours when the excessive UV rays are very destructive; 10AM to 4PM.

  2. Coconut oil
  3. Tomatoes
