What is the Difference Between SPF 30 and SPF 50?


Many people often ask us what’s the difference between Sunscreen SPF 50vs SPF 30 and why an older SPF 30 vs SPF 50 sunscreen meant to meet the current Indian standard with SPF 50 Gel blocks 98% of UVB rays where SPF 30 blocks 95% of UVB rays, but what's the real difference.

What is SPF?

What is SPF - Sun Protection Factor or SPF means the protection from UVB rays, which can cause cancer and many more problems.

In simple words, SPF increases the capability of your skin toleration from the sun's UV rays. If you can stand for 10 minutes under the sun until you experience a sunburn, then SPF 50 Sunscreen Gel for Oily Skin will increase that time by 50x helping you tolerate it for 500 or more minutes and your skin will not get burned.

How hard is for Sunscreen SPF 50 in summer in India from Suntan Protection?

Well… it's very hard for Sun Protective Cream. We all know about the hot temperature in India especially in summer, where some areas can reach up to 50-Degree Celcius.

Palodhi in Rajasthan is one of the hottest areas in India with a maximum recorded temperature of 51 Degree Celsius. If you are from Telangana, Maharashtra, Odisha, Uttar Pradesh you need Hight SPF for your Skin Protection. With the extremely high amount of UV rays take only a few minutes to get sunburnt during in summer in India.

What many people don’t realize is SPF30+ comes with the old standard of 1998, while SPF 50 comply with the latest standard 2012. This new 2012 standard brings some major improvements.

The most important improvement is in the UVA protection arena: UVA has been found to be primarily responsible for skin aging and skin cancer. 1998 standard did not impose any substantial protection against these UVA. This has been fixed by the 2012 standard.

The second improvement is the significant increase in claimable SPF. Many SPF 30+ (1998 standard) or SPF30 (2012 standard) products have an SPF of just over 30, while SPF 50+ sunscreens must have an SPF protection compared to SPF30 or SPF30+ sunscreens.

Best Sunscreen Gel, when applied correctly, is designed to reduce skin burn-time by the claimed SPF factor. In other words, if an unprotected skin burns in 5 minutes, it will burn in 300 minutes when protected by an SPF 50 sunscreen. By design, SPF 50 Cream is doubling the protection compared to SPF30.

How absorbing 1.3% more UV rays is doubling the protection?

It is easy to confuse transmission and absorbance, which are two different things. UV absorption increases by 1.3% going from SPF 30 to SPF 50, but the UV transmission rate is cut by half, and SPF protection doubled with Sun Protective Cream
The most important fact to remember is: what matters is not the UV rays that don’t reach the skin (absorbed), but those which do (transmitted).

To use a food analogy:

A 98% salt-free product contains 2% salt, and a 99% salt-free product contains 1% salt. The difference between the two products is not 1% of “salt-free”, but double the salt load, which can be the difference between life and death for some.

UV rays damage

It’s the UV light that reaches our skin that matters, and using an SPF 50 sunscreen doubles the protection compared to an SPF30 sunscreen. And that is a big difference.
SPF 50 Wins...

Our tip:

Most consumers don’t apply the dose used to determine sunscreen SPF performance. Our recommendation is to apply sunscreen liberally, let it dry, and then re-apply the same sunscreen again. This should help ensure a sufficient load of UV filters onto your skin to reach the performance required under our harsh Indian sun.

SPF 50 can do more than this; it comes in Sunscreen Gel for Oily Skin, an oil-free high SPF Sunscreen Gel which helps to make your skin non-stinky and gorgeous with a protective layer from the sun.
