Honestly, I don't know the importance of applying sun protection until early this year when I start looking into it and researching more about it. YEAH I'm that slow~ :(
(all information taken from dermtv.com)
Inadequate sun protection causes premature fine lines and age spots and even skin cancer. I honestly do not care quite as much about skin cancer. I'm more worried about premature aging and age spots.
YES THIS IS HOW VAIN I AM!
This is why we should protect our skin from the damaging UV rays!! Although this will be a long and boring post, but TRUST ME! It is useful to know all of these stuff! Maybe some of you already know but I just found out not long ago and I thought it is worth sharing :D
There are 2 types of sun protection you can use:
- Sunscreen
- Sunblock
*SURPRISED FACE*
IS THERE ANY DIFFERENCE??
I used to think they are the same but NO, they are not the same.
SUNBLOCK (a.k.a. physical sunscreen, mineral sunscreen, chem free sunscreen)
- sits on your skin and protects it by reflecting light off your skin. It acts like a mirror, bouncing off the damaging rays off your skin.
- has been in the market for a couple of years.
- main ingredients : Zinc Oxide and Titanium Dioxide
SUNSCREEN (a.k.a. chemical sunscreen)
- absorbs into your skin and acts like a sponge. It absorbs all the damaging UV rays to protect your skin.
- has been in the market for almost 40 years.
- main ingredients : Carbon-based chemicals
Both works the same in protecting your skin from UV rays.
There's just
1 important difference.
SUNSCREEN
have to be applied 20-30 minutes before you expose yourself to the sun because you have to allow some time for the chemicals to be absorbed into the skin and form the protection.
While, SUNBLOCK
works immediately after you applied it.
SPF means?
Sun Protection Factor. It simply means
how long you stay in the sun without getting a burn.
If it takes you 10 minutes on a nice sunny day to develop a burn under the sun,
SPF15 will allow you to stay in the sun for (10 minutes X 15) 150 minutes.
SPF30 will allow you to stay in the sun for (10 minutes x 30) 300 minutes. That means 5 hours!! @.@"
Is it necessary for you to wear sunscreen/sunblock everyday?
YES! Think of your skin as having a meter on the surface. Every time the sun hits it, it starts the meter and the meter starts to run continuously. Our skin can't differentiate whether we've been out in the sun for 5 minutes or for 15 minutes. When it's damaged,
it's damaged.
Secondly, even if it's a cloudy day, the bad UV rays are still able to penetrate the clouds and bring some UV rays with it to damage our skin.
So it is VERY IMPORTANT to apply sunscreen everyday before we step out of the door.
If I apply sunscreen/sunblock SPF30, then I apply foundation SPF15, do I get SPF45 (30+15)?
Unfortunately, you only get the SPF from the one you applied first which is SPF30. This is because the skin bonds with the chemicals in the first product you put on and the SPF doesn't double up.
What sunscreen/sunblock should I choose? Are higher SPF sunscreen better than lower ones?
Choose ones with the word UVA and broad spectrum.
Actually,
Sunscreen SPF15 - 88% protection from the sun
Sunscreen SPF30 - 95% protection from the sun
Sunscreen SPF60 - 99% protection from the sun
Using sunscreen past SPF60 like 80, 90, or 130, is not going to give you any additional protection. High SPF sunscreens also tend to be more thick and viscous thus repelling people from reapplying throughout the day because it doesn't feel nice on the skin.
That is why derm doctors always recommend SPF15 to SPF30.
Plus, high SPF sunscreens like SPF110 or SPF130 will conveniently 'suggest' to people that you don't need to reapply. In reality, the only way that you get enough sun protection is to
apply enough of sunscreen and
reapply throughout the day.
How much sunscreen should I apply?
There are people who wears sunscreen out in the sun but still get sun burnt. Why is that so?
Often, its because they did not reapply or didn't put enough sunscreen on.
Here's is a video to demonstrate the proper amount to apply chemical sunscreen.
For sunblocks aka chem-free sunscreens, here is another video to demonstrate how much you need to apply as you do not need as much as chemical sunscreens. Less is more here..
How often should I reapply sunscreen/sunblock?
If you are swimming, you should apply sunscreen every time you get out of the water. YES, even though the label of the sunscreen says waterproof or water-resistant! Those are just gimmicks because no sunscreen is really waterproof, water-resistant or sweat proof. -__-"
If you are sweating (jogging, tennis, doing any sports), you should reapply sunscreen as often as you can because sweat does an excellent job of washing off sunscreen.
Even if you are sitting under an umbrella, reading on the beach, you should reapply sunscreen every 3-4 hours. You may feel that you are not perspiring, but you actually are.
The rate of perspiration = The rate of evaporation
Makes you feel that you are not sweating but you actually are..
If I have make-up on, do I have to remove my make-up then reapply sunscreen? WTF?
If you make-up is still intact after 3-4 hours, that means your sunscreen is still intact. Therefore you have no need to remove you make-up then reapply sunscreen because that would be stupid. -__-" If your make-up has completely melted off, the there's a chance that your sunscreen has too. Then, you can reapply your sunscreen and your make-up.
In which order should I apply my sunscreen(chemical) in my skincare routine?
The CORRECT ORDER is,
CLEANSING --> TONER--> ACNE TREATMENT(if you use one) -->SUNSCREEN --> SERUM(if you use one) --> MOISTURIZER --> MAKE-UP
General rule of thumb, sunscreen always go first. This is because in for the sunscreen to work, it has to bind with the skin to form a chemical reaction in order for it to properly absorb the UV rays. Applying any other thing under the sunscreen prevents the sunscreen from absorbing properly and evenly into the skin. Toner is a prepper for things to absorb better so it is ok to go before sunscreen. Other than that, sunscreen almost always go first!!
For mineral sunscreen, you can apply before make-up or even on top of your make-up if you are using powder form (eg. mineral powder)
I think I've pretty much covered everything that I previously don't know about or am curious about.
All this info might make me seem a bit crazy and obsessed because of all the reapplying and the crazy amount to apply. Actually, I myself don't apply enough sunscreen throughout the day. So, we should start applying sunscreen properly because prevention is better than cure!
(if there is any cure for aging -__-").
I am now searching for my HG sunscreen/sunblock. What is yours? Please share with me by commenting below :D
Start protecting our skin together! Stay pretty and happy as always. Love y'all~ XOXO~
