I. Source and Properties
Totarol is a diterpenoid compound mainly extracted from the heartwood of New Zealand totara. It usually appears as a white to light yellow crystalline powder. In terms of solubility, totarol has good solubility in organic solvents but low solubility in water. At the same time, it has good chemical stability and can maintain its activity under appropriate storage conditions.

II. Main Effects
Antibacterial effect: Totarol strongly inhibits various bacteria, especially those causing skin problems like Staphylococcus aureus and Propionibacterium acnes. It stops bacterial growth on the skin by destroying cell membranes and interfering with metabolic processes, significant for preventing and treating skin inflammation like acne.
Antioxidant effect: As a powerful antioxidant, totarol removes free radicals in the body. Free radicals damage cells, causing dysfunction and aging. Totarol neutralizes them to protect cells, delaying skin aging and maintaining skin health and elasticity.
Anti-inflammatory effect: Totarol inhibits key inflammation pathways and reduces inflammatory factors, reducing redness and pain. For sensitive skin or skin easily inflamed, it soothes and maintains stability.

III. Application in Skin Care Products
Widespread applicability
Totarol is widely used in skin care products. In cleansing products, it can play a role in cleaning and sterilizing, removing harmful bacteria on the skin surface and preventing the occurrence of skin problems such as acne. In creams and serums, totarol can improve skin condition and provide comprehensive care for the skin through its antibacterial, antioxidant and anti-inflammatory effects.

Synergistic effect
Totarol has good compatibility with other skin care ingredients. It can work synergistically with common skin care ingredients such as vitamin C, vitamin E and hyaluronic acid. For example, when combined with vitamin C, vitamin C mainly focuses on whitening and antioxidation, while totarol plays a role in antibacterial and anti-inflammatory aspects. The two jointly provide more comprehensive care for the skin.
