Know Why? It’s so tempting to look for a high SPF (sun protection factor) to ensure we are protecting our skin, but did you know that the SPF isn’t the only thing to check out?

Don’t worry though, we’ve got you covered. This guide will te you everything you need to decode UVA, PA+++, PPD, broad spectrum, SPF and other sun protection terms on your Gel Sunscreen wherever in the world you bought it.

First of all a quick explanation as to which sunscreen should protect us from -The sun emits various rays of different wavelengths. We’re interested in the UVA and UVB rays as they cause the damage to our skin.

What are UVA and UVB rays?

UVB rays are the ones that cause burning. It is the sun screen’s SPF (sun protection factor) that indicates the level of protection from these UVB rays.

So it’s important to choose a best Sunscreen Gel with a good SPF - but what SPF is best? It's SPF 50 to get the best protection and it is suitable for all the skin types.

The SPF has little to do with the protection you get from UVA rays. It’s the UVA rays that accelerate ageing, because they break down the collagen and elating in the deeper layers of our skin. www.dermaessentia.com

So what does SPF mean?

Sun protection factor is a guide to the length of time you have protection from UVB rays only (the rays that cause burning). A sunscreen with an SPF of 15 will protects you against 93% of UVB rays whilst an SPF 50 blocks 98% of UVB rays - this is a lot of protection! Anything higher than this often gives people the wrong idea that they are being protected significantly more.

Even with a high SPF, regular sunscreen application is important after you’ve been swimming, doing sport or toweling yourself dry.

If the Sunscreen gel is: Made in US: If the cream’s critical wavelength (UV wavelength at which 90% of UVA light is blocked) is above 370nm, it is classed as broad spectrum. In recent years, the US adopted the SPF equivalence regulation that means that the cream’s UVA protection should be proportional to the SPF value.

Made in Asia, India: ‘Broad spectrum’ means the cream’s UVA factor is at least 1/3 of the UVB factor. This is based on evidence that the biological damage to the skin can be prevented and reduced if the ratio of the protection factor measured in the persistent pigment-darkening test. www.dermaessentia.com

What about Water Resistance?

No sunscreen is completely water resistant. Brands can only claim ‘water resistant’ if the sunscreen has been submitted for a special test.

The FDA requires companies to test the product's SPF value after 40 or 80 minutes in water. If it retains the SPF value, they may use the labels “water resistant” (for 40 minutes) or “very water resistant” (for 80 minutes).

Not all brands offer you "water resistant" sunscreen withstands 80 minutes immersed in water.

But there is some brand like Derma Essentia, working hard to give you a top notch product like Sunscreen Gel Based loaded with goodness. Water resistant sunscreen must be reapplied every 2 hours - especially after towel drying!
