SPF, SPF, SPF!
We hear all about it, everywhere, but do we really know what it is exactly and what we need to know? I’m sure that you're aware of it being relevant to protection from the sun, correct?
So, what is SPF and what are those SPF numbers? SPF stands for Sun Protection Factor. In other words, it is literally the time sunscreen will keep you protected from the sun. SPF 1, keeps you protected from the sun approximately for 15 minutes. So, what you have to do, is a quick multiplication to see how many minutes you will be protected under the sun! Bring out the calculators, we're doing math! To give you an idea, with an SPF 15 x 15 minutes of sun time =225 minutes. Now, 225min/60min= 3.75hrs roughly (almost 4hrs). Of course the needs and type of each skin varies with numbers. There are plenty of online SPF calculators that take into account skin type as well, just to make life easier.
After the given time it needs to be reapplied.
It’s quite important to re-apply SPF throughout the day, especially in the summer. There are countless factors that can affect SPF's duration; sweat, touching your face/body and removing it, swimming etc. We're not off the hook during the wintertime, keep applying it at all times! Yes, we're talking to all of you! Here's a simple yet detailed explanation as to why it is important and we keep talking about it. Please, grab sunscreens that have both UVA and UVB protection and here's why:
- UVB rays stand for UV - Burning
- UVA rays stand for UV - Ageing
- Both UVA and UVB can be damaging for the skin and we want to be protected from ageing as well as burning!
- Sunscreens were originally developed to protect only against UVB radiation, as the available filters - compounds were UVB absorbers. In the 1990s, compounds with UVA absorption capacity appeared. A lot of the companies out there still used the old filters unfortunately so we have to be cautious when we buy sunscreen.
- Sunscreens are very effective in preventing sun damage.
- Sunscreens are designed in formulas, using a sufficient number of different active compounds / filters to increase the range in radiation absorption and cover a wide range of protection (SPF 2 - 50) in Europe. USA, Europe, China and Australia have slightly different regulations - keep that in mind!
SO WHY IS SUNSCREEN SO IMPORTANT?
Sun and sunlight are very important when dealing with many physical and psychological diseases (many vitamins and hormones need sunlight to be synthesized). In recent years, because of the environmental damage, the ultra violet (UV) rays are not filtered properly by the atmosphere. Therefore, it's not wise to stay for an extended period of time under the sun. It can cause many skin problems ranging from minor burns, to premature ageing and skin cancer.
Most visible signs of skin ageing are the result of our cumulative daily exposure to the sun. These signs, in order to appear, need from 10 to 40 years. Photo ageing has increased over the last decades due to the change of our lifestyle and and the ozone hole.
Most skin reactions are caused by wavelengths of ultraviolet radiation A (UVA) and ultraviolet radiation B (UVB). Photo ageing starts from puberty, begins to appear clinically around 30 and is clearly visible after 40.
The skin is quite effective in protecting us against penetration from ultraviolet rays, but the depth of penetration depends on the wave length . Ultraviolet radiation A (UVA) reaches deeper into the skin layers, while the ultraviolet radiation B (UVB) is absorbed by the skin and only a little approaches the deeper layers of the skin.
TANNING. YES OR NO?
Tanning is also dependent on the UVA and UVB rays. Skin color change happens mainly from exposure to radiation UVA. The lightest skin type (type I) is not able to tan. Light skin (type II) can only tan with UVB radiation which is a slight sunburn. Darker skin types (type III and higher) tan, usually without burning. Sunburn causes apoptosis (cell death) - it burns the cells and if the dose is high enough, causes the cell renewal cycle to stop, therefore to age. So, always protect your skin with SPF, especially in long term sun exposure - even if you have a darker skin type. Long term sun exposure is a big NO, NO.
LONG TERM EFFECTS OF SUN EXPOSURE
The long-term effects of chronic sun exposure include photo-aging, skin cancer and suppression of the immune system. Given their ability to penetrate deeper into the skin, the role of ultraviolet radiation A (UVA) is considered particularly important for photoaging. UVA, has the ability to penetrate through windows too. Therefore, people who work in the office are affected!
Something FUN and interesting for all of you out there:
L'Oreal with La Roche Posay have developed a cool nail gadget - UV Sense - that sticks on your nail, looks like nail art and can give you an idea of your UV exposure through an app! How amazing is that? In other words it's the world's first battery free UV sensor and it's only 9mm small.
We've heard that it will cost around $40 and it will be available in the next year.

SPF goes last.
When using SPF, it would be better to double cleanse your face
