There seems to be some misconception every year about whether you need sunscreen in the winter. The simple answer to this is YES times a 100! Sunscreen really is the most important skincare product you can use every day to prevent premature skin ageing.
Even though the days may be cloudy and dark, invisible radiation from the sun can still inflict skin damage so it is essential to wear sunscreen in the winter.
Sun Damage in the winter
There are two types of ultraviolet radiation (UVR) that we are concerned about when it comes to skin damage - UVA and UVB. Although we often associate sun damage with hot, sunny days, UVA in particular is present all year round and is responsible for the majority of premature skin ageing.
This is why it is just as important to wear sunscreen in the winter as it is during the summer months.
- Long wavelength
- Can penetrate clouds, clothing, glass
- Cannot be felt
- Responsible for ageing
- Short wavelength
- Blocked by clouds, clothing, glass
- Felt as sunburn
Even though small amounts of UV radiation (UVR) are vital for Vitamin D synthesis and the immune function of the skin, it is responsible for 90% of premature skin ageing, known as photodamage.
UVR accelerates the destruction of collagen and elastin in the skin. These are essential structural proteins which give skin its strength, elasticity and suppleness. The amount of hyaluronic acid in the skin is decreased which reduces the skin's water binding capacity.
UVR exposure can also cause abnormal melanin (pigment) production. The combined result is reduced cushioning support for the skin and the development of signs of ageing.
Sun induced damage to the skin can result in:
- Sun spots
- Dry and dehydrated skin
- Broken capillaries
- Rough, uneven texture
It is well known that UVA and UVB radiation can cause skin cancer. Prolonged UVR exposure from natural sunlight, artificial sun lamps or tanning beds leads to damage of skin cell DNA directly or indirectly by the production of free radicals.
Our skin's normal immune response to abnormal cells may also be switched off by UVR which further allows development of skin cancers. Skin cancer is the 5th most common cancer in the UK. Furthermore 86% of melanoma skin cancer cases are preventable by using sunscreen regularly.
How much SPF do you need in the winter?
There are two types of sunscreen: chemical and physical.
Chemical sunscreens absorb UVR and dissipate it as heat. Physical sunscreens act as a barrier, reflecting and scattering UVR.
Sun Protection Factor (SPF) rates how well the sunscreen protects against UVB. PA rating is the Protection Grade against UVA. When buying a sunscreen, it is important to ensure it is broad-spectrum and a minimum of SPF 15 to ensure protection against UVA and UVB. Newer sunscreens also offer protection from bluelight, pollution and infrared which all contribute to skin ageing.
If you normally burn within 10 minutes, an SPF with factor 15, multiplies this time by 15. However, according to the Skin Cancer Foundation, higher altitudes, snow and strong winds can wear away sunscreen, reducing its effectiveness so it is recommended you reapply every two hours to ensure all day protection during the winter.
Snow also reflects sunlight, making you more susceptible to sunburn, so an SPF of 30 or higher is recommended.
A higher SPF is also recommended for people with very fair skin, history of skin cancer, skin conditions like system lupus erythematosus, recent chemical peel, using retinol or taking oral isotretinoin. For those with sensitive skin or rosacea, avoid sunscreens with fragrances, alcohol and preservatives.
For those with skin sensitivity issues, sunscreens which contain ingredients like titanium dioxide or zinc oxide may be beneficial.
Newer formulations have significantly improved and no longer give a white complexion.
For those with dry skin which is even more common in the winter, consider sunscreens combined with moisturisers or those in cream or balm form. Gel sunscreens are also available with ingredients for blemish-prone skin.
