The difference between SPF15 & SPF30 in sunscreen

Did you know?

The difference between a physical sunscreen that has an SPF 15 & SPF 30 is 3% protection from UV rays.

• SPF 15 – 94% protection
• SPF 30 – 97% protection

A physical sunscreen only remains on the surface of the skin so is easily removed with moisture & it must be reapplied regularly if there is any chance of it wearing off.

• That the SPF relates to your burn time? So if you burn in 10 minutes then with an SPF 15 you have 15 times 10 minutes protection which is 150 minutes protection then you must reapply.

Chemical Sunscreens are the most suitable for swimming or physical activities because they absorb into the Stratum Corneum (top layer of skin) & do not move. They too must be reapplied as recommended.

• SPF 50+ sunscreens. Despite the higher protection factor, SPF 50+ does not give you significantly higher protection & will still require reapplication every 2 hours. An SPF 30+ will remain, & will still be regarded as more than sufficient protection from UV radiation.

Not all sunscreens are equal – not all chemicals are of a similar make-up – some can be destructive in the skin so it pays to buy a sun protection that is “made to care for & protect your skin”.
