Researchers have confirmed that rosemary promotes wound healing thanks to carnosic acid, a natural antioxidant in this herb. This substance activates a nerve sensor that stimulates the regenerative processes of the skin and improves healing without the formation of scars, which has been demonstrated in mice. Rosemary has been shown to be more effective and gentler compared to other herbs or compounds targeting the same mechanism. Research suggests that rosemary could be a cheap and effective option for reducing scarring in humans. In addition, rosemary has antibacterial and anti-inflammatory properties that help treat acne and improve overall skin health. Carnosic acid also slows down the aging of the skin and promotes its regeneration. This natural antioxidant is the subject of further studies for its potential use in dermatology and cosmetics.
