Why is Sunscreen Essential for your Skin? 

We all know that Sunlight is essential for us in many ways. However, do you have an idea that the sun rays between 11 am to 4 pm emit UVA and UVB rays, which can harm your skin in the most unexpected way? It can cause skin issues such as wrinkles and in worst cases photo damage and some skin cancers. Strikingly, not just outdoors but inside your home and offices you should apply sunscreen to protect your skin from UVA and UVB rays. Usually, people who are born near the equator have dark skin tone and those who are from tropical regions have brown skin tone and temperate regions have lighter skin tone. But the good thing is that you can always protect your skin from tanning, burning, aging and other harmful effects easily.

What is SPF?

SPF stands for Sun Protection Factor. SPF 15 blocks 93% of UVB rays, SPF 30 blocks 97%, and SPF 50 blocks 98%. A sunscreen between 30 to 50 SPF provides good sun protection.

Benefits of Sunscreen

  • Ideally sunscreen for Indian skin tone should be of 20 to 40 SPF. The SPF goes off within two hours of application. Sunscreen is an active product. This is why, it is important that the application should be repeated every two hours during the day.
  • The purpose of sunscreen is to shield the body from the sun’s ultraviolet rays which leaves several harmful effects such as sunburn, aging, pigmentation and skin cancer promotion. The sun rays are separated by their different wavelength into types such as UVA and UVB which exert a variety of effects in the skin due to the absorption patterns of chromophores. 
  • The primary two chromophores are hemoglobin found in our red blood cells and melanin which gives our skin its pigment.
  • There are two basic types of sunscreen: physical and chemical blockers.  Physical blockers like zinc oxide or titanium dioxide reflect the sun’s rays by acting as a physical barrier.
  • Chemical blockers absorb the sun rays and they deteriorate more quickly than physical sunscreens because their ability to absorb the sun diminishes.  
  • Wearing sunscreen helps to protect against the development of all three types of skin cancer, cell carcinoma, squamous cell carcinoma and melanoma.
  • On a daily basis the DNA in your cells is developing mutations and errors that are handled by mechanics within your cells.Ultraviolet rays from sun leads to mutations that lead to uncontrolled growth.
