Researchers have pointed to the effectiveness of rosemary in skin care

Researchers from the Perelman Medical School of the University of Pennsylvania have found that a natural compound in rosemary leaves can help wounds heal more efficiently without scarring. This was reported on December 7 by Science Daily magazine.

"Many skin lesions leave scars, and in some people this can lead to long-term cosmetic and even functional problems. Our results show that rosemary extract, and in particular the antioxidant carnosic acid, can switch the healing process from scarring to healthy skin regeneration. We do not have proven methods to achieve this in humans," said Thomas Lung, senior author of the study, MD, associate professor of Dermatology at the University of Pennsylvania.

The idea of the project arose after observing social networks, where many bloggers recommended serums with rosemary and products for better skin restoration. University of Pennsylvania students Jiyai Pang and Emmanuel Repp Reyes contacted Dr. Lung to find out if these claims have a scientific basis. According to Pang, they suggested that there is some truth in the popularity of this trend, since rosemary itself contains many antioxidants.

Lung conducted a series of laboratory experiments. Working with mice, the research team created a cream based on carnosic acid, a natural antioxidant found mainly in rosemary. The cream accelerated wound closure and helped restore structures such as hair follicles, sebaceous glands, and cartilage.

The scientists also found that this component activates the skin nerve sensor TRPA1, which was previously associated with the ability to heal without scarring. When the cream was used on mice without TRPA1, the regeneration effect did not appear.

"We have also identified other herbs such as thyme and oregano that can activate TRPA1. But rosemary stood out for its effectiveness and safety. It is known that other natural ingredients, such as mustard oil <...>, also stimulate the TRPA1 receptor, but unlike rosemary, they can cause irritation and inflammation," said study co—author Rapp Reyes.

Scientists have found that the regenerative effect of rosemary works only in those areas where a cream with carnosic acid is used. Applying the cream to areas of the skin far from the wound did not lead to scar-free healing. This emphasizes that its benefits are strictly local.

The research team recommends consulting with your doctor before adding rosemary products to your skin care regimen or creating homemade blends. However, since rosemary is widely available and inexpensive, the scientists hope that their findings will prompt more in-depth research into its potential to treat wounds in humans, especially those prone to significant scarring.

On November 30, cosmetologist Anastasia Shibaeva and experts from the Golden Apple told Izvestia about skin hydration during the heated season. According to experts, dryness worsens the appearance of fine wrinkles and exacerbates chronic dermatoses, including eczema, atopic dermatitis and acne. It was clarified that basic home care with gentle cleansing without aggressive surfactants should be established for care. The experts named foams and cream gels as preferred.
