Sunscreens are an important part of a complete sun protection strategy. Given the humid temperature and heatwave in Singapore, it is especially essential for Singaporeans to travel around with sunscreen to prevent tanning or sunburn from the harmful UV rays.
Sunscreen has been proven to decrease your risk of skin cancers and skin precancers. Regular daily use of SPF 50 sunscreen can reduce your risk of developing squamous cell carcinoma (SCC) by about 40 percent, and lower your melanoma risk by 50 percent. It also helps to prevent premature skin aging caused by the sun, including wrinkles, sagging and age spots.
Who should use it?
Men, women and children over 6 months of age should use sunscreen every day. This includes people who tan easily and those who don’t — remember, your skin is damaged by sun exposure over your lifetime, whether or not you burn. Babies under the age of 6 months have highly sensitive skin, however, the Theo10 Sunscreen is formulated in such a way that it is suitable for babies and adults with extremely sensitive skin.
Effect of UV rays on our skin
UV (ultraviolet) radiation has a shorter wavelength than visible light. Much of the energy emitted by the sun is in the form of UV, although our planet’s atmosphere – particularly the ozone layer – does a good job of filtering most of this type of radiation out before it reaches us. However, some UV rays are still able to penetrate the ozone layer and enter our surroundings. Without any protection from the atmosphere, UV is a significant hazard for astronauts: if their skin was exposed they would be burnt in a matter of seconds. And even down on Earth, it makes sense to be cautious, as UV rays can cause sunburn as well as more permanent damage to your skin or eyes. How much UV radiation you’re exposed to when out and about depends on several factors, including proximity to the equator, altitude, time of day, season and cloudiness. UVB radiation is to blame for sunburn, whilst UVAs are responsible for long term skin damage. Thankfully, sunscreen can protect us from both these invisible enemies.
What does SPF mean?
SPF stands for Sun Protection Factor. The number tells you how long the sun’s UV rays would take to redden your skin if you apply the sunscreen exactly as directed compared with the amount of time without sunscreen. So, if you use an SPF 30 product properly, it would take you 30 times longer to burn than if you used no sunscreen.
The Skin Cancer Foundation advises that the best sunscreen is the one you are most likely to use, so long as it provides safe and effective protection, and is broad spectrum with an SPF 15. YN
Physical Sunscreen vs Chemical Sunscreen
Firstly, let us clarify the differences between 2 types of sunscreens.
Physical Sunscreen creates a physical barrier to block and scatter the rays before they penetrate your skin. They usually contain natural ingredients such as zinc oxide and titanium dioxide.
Whereas chemical sunblock uses chemicals such as avobenzone and octisalate to absorb UV rays before they can damage your skin. Since there are chemicals involved in the latter, it may be harmful and may cause irritation with those with extremely sensitive skin especially when there is absorption involved. This explains why physical sunscreens are a more popular option.
As the name suggests, physical sunscreen filters the harmful rays that your skin is exposed to. Like chemical sunscreen protects you from UVB rays, physical sunscreen protects you from UVA rays, where the ‘A’ stands for aging. Physical Sunscreens help to filter out UV radiation using a combination of two main types of active ingredients. Inorganic particles, such as titanium dioxide or zinc oxide, form a physical barrier, reflecting or scattering UV waves. Organic components meanwhile absorb UV rays and release their energy as heat. The light-reflecting inorganic compounds meant that early sunscreens were almost indistinguishable from white paint. Nowadays though, nanotechnology has made it possible to produce completely clear sunscreens which still fend off UV rays just as effectively. They contain the same ingredients as traditional formulations, but the inorganic particles are so small that they are invisible. So, while sunblock works chemically, sunscreen works physically preventing and repairing any long-term damage to the skin.
A chemical sunscreen’s primary job is to protect you from the UVB rays. The ‘B’ here stands for burning. Chemical Sunscreens contain organic (carbon based) compounds, such as oxybenzone, octinoxate, octisalate and avobenzone, which create a chemical reaction and work by changing UV rays into heat, then releasing that heat from the skin. They are often referred to as chemical or organic absorbers. These sunscreens can possibly cause an increase in existing brown spots and discoloration due to a higher internal skin temperature ( overheated skin can make brown spots worse, such as melasma). They are usually thick in consistency which results in an undesirable whitening effect on your skin. Chemical sunscreens also require about 20 minutes after application before it starts to work. They increase the chances of irritation and stinging (especially for those who have dry skin with a damaged moisture barrier) due to the multiple ingredients combined in order to achieve broad spectrum UVA and UVB protection as well as an increased chances of redness for rosacea-prone skin types because it changes UV rays into heat which can exacerbate flushing.
THEO10 Moisturising Sunscreens
Similar to our other products, we formulated a physical sunscreen, without the use of artificial chemicals, that possess the ability to protect us from UVA and UVB radiation. The SPF value of 50 ensures that the barrier lasts for 8hrs which is more than sufficient for the amount of time spent outdoors under the hot sun. We added a moisturising agent in the sunscreen as we understand that many people who have used sunscreens tend to have dry skin due to the added barrier. We have also ensured the safety of our sunscreens to be suitable for all skin types especially those with extremely sensitive skin. Theo10 sunscreens can be applied on the skin and even on the face. Due to the rich content, its fingertip size amount is more than enough to be spread over your arms. Even better, the sunscreen has been proven to not whiten your skin. We used nano technology to ensure that the particles in our sunscreen is not small enough to be absorbed into our bloodstream as this may cause harmful side effects and are commonly unnoticeable in other commercial sunscreen brands. At the same time, the particles are not big enough to clock pores. Last but not least, the THEO10 sunscreen has been made sweat and water-resistant to ensure the long-lasting effectiveness of the protection!
