Carnosol Acid

Description

Carnosol acid, also known simply as carnosol, is a naturally occurring phenolic diterpene compound found primarily in rosemary (Rosmarinus officinalis) and sage (Salvia officinalis). This potent antioxidant has gained significant attention in the skincare industry due to its multifaceted benefits for skin health and protection.

Structurally, carnosol acid features a phenolic structure with a diterpene skeleton, contributing to its strong antioxidant properties. It effectively neutralizes free radicals and reduces oxidative stress, which can help prevent premature aging and cellular damage. Research has demonstrated carnosol's ability to inhibit matrix metalloproteinases (MMPs), enzymes responsible for breaking down collagen and elastin in the skin.

Carnosol acid exhibits anti-inflammatory properties, potentially benefiting conditions such as acne, rosacea, and general skin irritation. Studies have also shown its potential in regulating sebum production, making it a promising ingredient for oily and acne-prone skin types. Additionally, carnosol has demonstrated photoprotective effects, helping to shield the skin from UV-induced damage when used in conjunction with sunscreens.

In skincare formulations, carnosol acid is typically incorporated at concentrations ranging from 0.1% to 1%, depending on the specific product and desired effects.
