There’s much to look forward to with the arrival of winter, especially the cozy clothing options and fun holiday getaways. Unfortunately, the magic of this chilly season isn’t welcome news for our skin. This time of year is known for drying out the skin, and while there are plenty of options for treating common winter skin woes, skincare experts agree that topical vitamin E is a must-try for moisturizing.

To buy: amazon; $20 (originally $25)

Celebrity esthetician Sarah Akram confirmed to Travel & Leisure that vitamin E is “powerfully moisturizing,” adding, “[It’s] known to protect the skin from free radicals, and free radicals are a cause of premature aging. It is also known to aid your skin in promoting the cell turnover process to help your skin cells regenerate.”

More research regarding the long-term moisturizing benefits of vitamin E is needed, dermatologist Dr. Rachel Maiman tells Travel & Leisure, but she noted, “Two small studies have shown topical application of vitamin E can improve skin water-binding capacity after two to four weeks of use.”

Both Maiman and Akram cautioned that vitamin E might not be ideal for all skin types, especially those that have acne or excess face oil. “It has the potential to be comedogenic, meaning it clogs pores. Although it’s very uncommon, topical vitamin E can also act as an allergen to some, causing irritation, itching, or even a rash when it touches the skin, so it should be avoided in those who are very hyper-sensitive,” Mairamn said.

It’s best to conduct a patch test before introducing anything new to your skin, but customers with skin sensitivity confirmed they were able to use this serum. “I was hesitant to buy this product because I have super sensitive skin/reactions to almost everything I use. However, I have had no negative effects using this product and am very happy with it! My skin has definitely smoothed out and seems to be glowing,” a reviewer shared.

There’s no telling how long this current sale will last, but now’s your chance to try the serum with thousands of glowing reviews for just $20.
