Aloe-Fortified Yogurt May Improve Skin Quality, Appearance

Previous studies have shown that aloe sterol stimulates collagen and hyaluronic acid production. A new study investigated the effect of aloe sterol on skin conditions and found that it may improve skin elasticity, skin moisture, collagen score, and transepidermal water loss.


Participants in the study included 64 healthy adult Japanese women between the ages of 30 and 59. They were given either an aloe sterol-supplemented yogurt drink or placebo for 12 weeks. The women were required to not have eaten food that harms the skin’s condition, not use cosmetics and creams on their arms apart from sunscreen, not have allergic diseases with sleep disorder, and not have any skin conditions.


Both groups had higher barrier integrity of the skin during the test period, when compared with baseline levels. However, the forearm skin hydration levels of the aloe sterol group were significantly greater than the placebo group at weeks four, eight, and twelve. Skin elasticity levels increased for the aloe sterol group at 4, 8 and 12 weeks, while the placebo group had lower elasticity levels at weeks 8 and 12.


The researchers also conducted ultrasound images on three participants in each group before and after 8 and 12 weeks. They found that the aloe sterol group had expansion of high collagen score regions in the tested area, when compared with the placebo.


Researchers from Wakayama Medical University in Japan conducted the study. It was published in the February 2017 issue of Skin Pharmacology and Physiology.


Aloe vera has been linked to a number of health benefits, including helping to heal burns and insect bites, improved oral health, lowering inflammation, improving digestion, improving blood sugar control, and improving cholesterol and triglyceride levels. It can be consumed as a juice, applied topically, or taken in supplement form.
