We have often heard dermatologists talking about SPF and the levels it comes in.The term SPF stands for Sun Protection Factor which provides the level of UVA and UVB protection by the sunscreen. There are different levels of SPF accessible in many different brands like SPF 15, SPF 30, SPF 50 etc.
Before choosing a sunscreen, it's very important to know your skin type and choose the one that's best for your skin type. 3MEDS, the best online pharmacy in India points out other important factors that need to be taken care before choosing the best sunscreen for your skin -
Sunlight has both harmful UVA and UVB rays. UVB rays cause sunburns and damage the skin’s DNA. Whereas , UVA rays penetrate the skin causing wrinkles and dark spots. So,it's important to always go for a Sunscreen with a broad spectrum which offers protection from both UVA and UVB rays.
The next important thing to consider before buying a Sunscreen is to choose a product with an SPF of 30 or higher . A sunscreen with a higher SPF offers more protection from the sun’s harmful rays and eliminates the requirement to apply the sunscreen at regular intervals.
A good sunscreen should always be both water and sweat resistant. Ordinary sunscreens which are not water resistant are sticky and need to be re applied at regular intervals.
A number of other chemicals like avobenzone, oxybenzone, etc present in sunscreens get absorbed by the skin and are extremely harmful. But chemical blockers like zinc oxide, titanium oxide and other zinc based products do not get absorbed in the skin and offer a broad spectrum protection to the skin.
It's very important to go for a trusted brand when it comes to choosing the ideal sunscreen for the skin. A good brand product with trusted and proven ingredients will help provide better protection to Sun's harmful rays.
It's important to buy the freshest possible stock of sunscreen as its ingredients tend to break down very easily with each passing day. Hence the more fresh the sunscreen is , the better the efficacy of it.
Sunscreens which are either sprays or powder are basically mineral-based and contain a number of nanoparticles that may enter the bloodstream and cause various health issues. Hence it's wise to avoid products which are powdery or spray and stick to cream-based alternatives.
