Its rich nutritional value and multiple skincare benefits are leading more and more skincare brands to choose it. This article will delve into the benefits of rosa roxburghii extract for skin health, analyze its mechanisms of action, and provide professional advice on its use for different skin types.
 
Nutritional Value and Composition Analysis
 
Rosa roxburghii is the fruit of the wild rose and is known as the "king of natural vitamin C." Analysis shows that rosehip fruit is rich in a complex of vitamins, including vitamins A, B vitamins, vitamin C, and vitamin E.  The vitamin C content is particularly high, far exceeding that of citrus fruits.
 
Mechanism of Action of Rosa roxburghii Fruit Extract
 
1. Antioxidant Protection Mechanism:
The extract is rich in vitamin C and other antioxidant components that can directly scavenge reactive oxygen species, preventing oxidative damage to skin cells.  It can also work synergistically with other components to form an antioxidant network, improving overall antioxidant efficiency.
 
Enzyme Activity Regulation: Activates endogenous antioxidant enzymes such as superoxide dismutase (SOD) and glutathione peroxidase.

Inhibits collagen degradation: Antioxidant components protect collagen from damage by free radicals and matrix metalloproteinases.
 
3.Anti-inflammatory and Repair Mechanism:
 
Rosa roxburghii extract has an inhibitory effect on skin pathogenic bacteria such as Propionibacterium acnes and Staphylococcus aureus.
In addition, it can promote wound healing, accelerate epidermal regeneration and granulation tissue formation.
