Did you know? UV protection for Autumn & Winter

SUNCUT provides complete
full-body UV protection all year round!

Ever thought that you don’t need to bother with UV protection for a while, now that the hot summer’s over?
The amount of UV rays in the environment fluctuates depending on the season, but they’re still there all year round. Compared to summer, short wavelength UVB rays decrease by about 80% in winter. Yet the UVA rays that penetrate deep into your skin only decrease by 50%.
So make sure to protect your skin and hair from UV rays in autumn and winter too!

POINT 01POINT 01
For outings in autumn or winter,
like trips and winter
sports!

Autumn is the season to go on trips, while winter is for snow sports. UV protection is also a must during these seasons, when you find yourself going out often.
It’s especially important to protect yourself from reflected sunlight on snowy days, as the reflection rate of UV rays off fresh snow is extremely high at 80%. Before going out, make sure you apply SUNCUT Gel or Essence to your body and beneath your makeup, and regularly reapply sunscreen over your hair and makeup using our Spray when outside.

POINT 03POINT 03
There are more hours of sunshine in winter than in summer!?
Don't forget your daily UV protection

Total hours of sunshine by month Total hours of sunshine by month

You may think that, because the days are longer, there are more hours of sunshine in summer. 
Actually, there is more in winter.
The days are shorter in winter, but there are a lot of clear days. The likelihood of a clear day is quite low in July at 40% on average, and in August at 54%, but this is much higher in December at 71% and in January at 72%. You can also see from the above graph that there are more total hours of sunshine in winter than in spring or summer.
Don’t let your guard down just because it’s autumn or winter—make sure to wear UV protection daily.

POINT 04POINT 04
You're more vulnerable to UV rays
in autumn and winter when you're not so tanned!

Melanin—the cause of dark spots and freckles—tends to be thought of as the bad guy, but it actually has a role in protecting your skin from UV rays.
Compared to when your skin tone is darker due to tanning, your skin has less melanin when you are not tanned, making it more vulnerable to the effects of UV rays.
That means skin damage might accumulate just when you feel safe because your summer tan has faded!
The key to UV protection, is doing it all year round.

Autumn Autumn

In autumn, your skin will feel warn out due to the impact of summer UV rays.
This is also when humidity starts to decrease, making your skin is prone to dryness, so make sure you thoroughly moisturize and remove dead skin cells to keep your skin in good shape. UV rays will still be strong on many days, so keep up the UV protection.

Winter Winter

In winter, UV rays are said to be weaker, but UVA rays do not fluctuate much depending on the season. Don't drop your guard! The air is also dry during this period, so make sure you help skin stay hydrated by using enough moisturizer, and prepare it for spring when UV rays will increase again by using our UV protection Essence.
