It can be very easy in this small cold country to let your SPF slide in winter. But it’s a common misconception that we only need to apply sunscreen when the sun is out or when it’s hot. Unfortunately, the sun’s UV rays don’t shut off in the winter, although it may feel like it sometimes! Even when it’s dull, the silent killer UVA rays shine though.
What are UV Rays?
The sunlight that reaches us is made up of two types of harmful rays: long wave ultraviolet A (UVA) and short wave ultraviolet B (UVB). UVA rays penetrate deep into the dermis, the skin’s thickest layer.
Unprotected exposure can lead to premature skin aging and wrinkling (photoaging). UVB rays will usually burn the superficial layers of your skin and plays a key role in the development of skin cancer.
The difference between UVA & UVB
UVA - A for AGEING! These rays can be hidden behind the clouds and you mightn’t feel them, but they are still attacking our cells and causing ageing on the skin. Most of us are exposed to large amounts of UVA throughout our lifetime. It is important to remember that the sun rises every morning and sets every evening and although it may not be tropical weather – it’s still there!
UVB – B for BURNING! UVB is the chief cause of skin reddening and sunburn and tends to damage the skin's more superficial epidermal layers. It plays a key role in the development of skin cancer, tanning and photoaging. Its intensity varies by season, location, and time of day.
Yon-Ka SPF25 & SPF50 protect from both rays naturally and both products are even recommended for the most sensitive skin. With broad spectrum lightweight protection, the products also contain age-preventing and hydrating ingredients such as fruit acids, vegetable glycerine and wheat germ oils.
