A team of German scientists has developed an oral supplement to help women look younger.
The study published in the International Journal of Cosmetic Science found that pills made from different compounds from plants decreased wrinkles up to 10 percent and prevented the development of crow's feet, which are wrinkles that appear around and on the side corner of eyes with age.
The invention is expected to help avoid the huge amounts spent on Botox, the invasive method currently available to treat the wrinkles.
The study included 166 women, aged around 61. The women received Dove Spa Strength Within supplement for 14 weeks. The supplements were made of soy isoflavones, omega-3 fatty acids, vitamin C, vitamin E and antioxidant lycopene, Mail Online, UK reported.
The whole group was divided into two, based on the treatments they received- low or high dose of the pill (111) or placebo (53).
Researchers made silicon moulds of the participants' crow's feet, both before and after the treatment. Skin of the women who received the plant pills had become smoother, with a reduction in the wrinkles. The pills helped to achieve a smooth, young skin by increasing the production of collagen, a major protein in the human body. Nearly 30 percent of the protein content of the body is collagen, which is widely known as the glue that holds the body's cells together. It helps in strengthening skin's elasticity by supporting blood vessels.
The current study re-confirms a 2011 study conducted by the same researchers. During that time, the pills helped reduce wrinkles up to 30 percent.
Oestrogen levels in the body go down with ageing, affecting the production of collagen, the researchers, said.
"It shows there is a link between dietary ingredients and the quality and the ageing rate of skin. We find it works better on deeper wrinkles," Professor John Casey, vice-president for biological sciences at Unilever, Dove's parent company told Daily Mail.
