How can Sunscreen lotion with SPF 50 protect one from sunburn? First of all, let look at a short explanation on how sunlight is the danger to our skin. Sunlight that comes through the ozone layers enters the Earth with the wavelength of 290 – 760 nanometers. The wavelength is grouped into three sections, which vary from 290 – 320 nanometers is UVB or (UV) and they vary from 320 – 400 nanometers is a UVA and then the range from 400 – 760 nanometers can see with our eyes, known as plain radiation. These radiations, more so from UVB and UVA, will create physical as well as chemical reactions with the skin, which might end up in skin cancers. So, people have to consider protecting the skin from the dangerous rays and one of one of the best tactics is using the Sunscreen lotion with SPF 50.

There are 2 types of how sunscreens protect the skin from sunlight, which is physically and chemically. Chemical sunscreen absorbs radiation into the chemical’s molecule in order to convert the radiation into heat, rather than letting the radiation to go through the skin into the dermis part. Some sun lotion just soaks up UVA radiation and other sun lotion only soaks up the UVB radiation, but there is as well sun lotion that might absorb both UVA as well as UVB radiation. However not one of the suntan lotions that might soak up the radiation. Physical sun lotions reflect the radiation out of the skin. The two most popular chemicals that can be used as physical sunscreen are Zinc Oxide and Titanium Dioxide, but Zinc Oxide is not as white as the Titanium Dioxide and it might reflect the UVA, UVB,  and the plain radiations.

People who plan to get a Sunscreen lotion with SPF 50 product need to choose rigorously. The most important considerations before buying sunscreen product are the ingredients. The ingredients that are added should have the capability to absorb and reflect UVA, UVB and visible light emission. Make sure that the ingredient concentration is not too high or not too low since if it’s too high it can harm the skin, while if it is just too low it might be ineffective. Another thing to consider is the quantity of SPF and PA.

SPF is to measure the ability of the sunscreen, how much it can protect from the UVB rays. The SPF number indicates how frequently this sun lotion might protect from the UVB radiation. For example SPF fifteen, this means that this sunscreen has the ability to protect UVB radiation 15 times from skin. Put simply, if someone’s skin gets the sunburn after standing in the sun for 15 – 30 minutes and if that person uses SPF 15 suntan lotion on the skin, the sunscreen will guard the skin against third-party burns 15 times, which comes to around 3 – 4 hours.
