Kate Middleton's secret to glowing skin is in this surprisingly affordable beauty oil

The Royal Duchess’ soft and glowing complexion has had a lot of questions as to how she maintains the youthful and elegant look. While she has been blessed with a complexion fitted for royalty, many would ask how she takes care of her skin or, more particularly, what products she uses.

From being a mother of two lovely children to her duties as Royal Duchess, which might take some time off her sleep, to attending important events left and right, it really is quite puzzling how Kate appears to get even younger and lovelier as she matures. Surprisingly, her secret is not as complicated and exclusive as one would expect from any member of the royal family. Her favourite product is actually quite affordable and easy to avail.

People reports that Kate’s secret to her porcelain like complexion lies in a $65 beauty oil by Beuti Skincare called Beauty Sleep Elixir. It is an all natural mixture of 14 plant based oils which include camellia oil, cherry seed oil and seabuckthorn oil, among many others. These are very rich in antioxidants and nutrients that enable it to fight against skin aging and inflammation.

Well and Good reports that the ideology behind Beuti’s product is to fight what they call “inflammaging,” which expert dermatologists would define as a persistent and prolonged state of skin being inflamed which lasts for a considerable span of time. This can be caused by overexposure to the direct heat of the sun, harsh skin products or pollution. When the skin becomes inflamed, the skin’s supply of collagen and elastin degrades. This makes the skin to show more signs of aging.

Beuti founder Leila Aalam reveals that Kate loves this product so much, she keeps three bottles of it on her bedside table. The many benefits of this product has made it part of the Royal Duchess’ pre-bedtime routine.

As of now, Beuti only sells this product, although they plan to expand their product line to contain several others which would include a cleanser, a collagen building serum and a cream. They plan to release these products in the upcoming months.
