How to Choose a Safe Sunscreen

Sunscreens help protect you from the sun's harmful ultra-violet radiations in two ways... Some sunscreens work by spreading the light and reflecting it away from your skin. While others absorb the ultra-violet radiations before they reach to your skin.


In the past, choosing the best sunscreen meant you just want a high sun protection factor or SPF which tells how much the sunscreen fights against ultra-violet B which is one type of cancer causing UV rays. Studies soon revealed that ultra-violet A rays can also cause a skin cancer threat. While UVA radiations do not result sunburn, they go through deeply into skin and produce wrinkles. The Ecological Protection Agency reports that up to 90 percent of skin changes connected with aging is really due to a regular exposure to UVA radiations. In order to avoid all of above threats, choose sunscreen wisely.


Avoid Harsh Chemicals

 

Oxybenzone is connected to hormonal interruption and can result sensitive reactions. EWG suggests selecting products with one of the following ingredients:
·    Zinc
·    Titanium dioxide
·    Avobenzone or Mexoryl S

SPF Values


The SPF number on your sunscreen is for sun protection aspect and whether you believe it or not, a higher number does not mean more protection. The EWG suggests buying sunscreens with SPFs higher than 15 but not higher than 50. Researches prove that sunscreens with an SPF higher than 50 do not give high protection, and even many skin experts claim that a higher number forces many people to think sunscreen remains longer than one with a lower SPF, resulting them to re-apply less often, so they are more at threat for burns.


Water Resistance


The FDA also describes waterproof sunscreen as significance that the SPF level remains effective after 40 minutes in the water. High water resistant means it remains active even after 80 minutes in the water. These sunscreens or sun blocks are in no way water proof, so you will need to re-apply them consistently if you are swimming.


Sunscreen Suitable for Your skin


People who have very sensitive skin or skin problems can also benefit from using sunscreens made for children. Go for organic sunscreen instead of using chemicals like oxybenzone, para-aminobenzoic acid (PABA), sulisobenzone, or dioxybenzone. If you have skin infection or allergies, also avoid skin care products with fragrances, alcohol, or other harmful preservatives.
