Sun damage in the winter
Sun damage is influenced by ultraviolet (UV) radiation, not the temperature outside. A cool or overcast day in winter can have similar UV levels to a warm, sunny day. In fact, in winter months, UVA radiation is higher. On the other hand, UVB radiation decreases during the winter months. Both UVA and UVB contribute to skin cancer. However, UVA is thought to play a more dramatic role in premature aging.
Of course, you should still go outside in winter as vitamin D is called the sunshine vitamin since it is made in the skin after exposure to sun. Vitamin D is crucial thus going outside in winter is needed but don’t forget to wear sunscreen. Apply for example a broad-spectrum sunscreen with a SPF of 15 or higher to all exposed skin.
Light facial formulations
As most of the consumers don’t like the rich creams on their face, it is necessary to formulate light facial sunscreens. To improve skin feeling, light emollients play an important role. Oleon’s emollient Jolee 7202 (Propylene glycol diheptanoate) is a very light emollient and has a dry, powdery afterfeel which makes it an ideal emollient for daily suncare formulations. This silicone-like emollient gives an excellent spread, absorption and unique lightness onto the skin. This product is also an effective UV filter solubilizer for organic UV filters. Combine this emollient with Radia 7220 (Coco-caprylate/caprate) to further improve the skin feeling as this light and natural emollient softens the skin. Jolee 7202 and Radia 7220 are natural derived emollients and ideal to formulate sustainable and green formulations.

Formulating for sensitive skin
Especially those with a more sensitive skin should choose wisely a suncare product. Dermatologist tend to recommend suncare products containing inorganic UV-filters or also called physical UV-filters such as Titanium dioxide and Zinc oxide. Reason is that these UV-filters are less likely to cause irritation or rosacea flare-ups. However formulators struggle to find an effective wetting agent to disperse these UV-filters. Oleon’s Jolee 7181 is a safe ingredient for the skin and shows effective pigment dispersing properties for inorganic UV-filters. This product is a highly protective film former which further contributes to shield the skin from waterloss and UV radiation.
