Ingredient review
Bayberry Bark Extract
INCI: Myrica Cerifera Bark Extract
A gentle botanical extract with astringent and soothing potential, but human studies are limited.
In plain English
Bayberry bark extract comes from the bark of a shrub native to North America. In skincare, it is used mainly for its astringent effect, which means it can help tighten pores and reduce excess oil on the skin. It also has some soothing properties, making it a nice addition for oily or combination skin types. However, most of what we know comes from lab studies, not large human trials, so its benefits are not fully proven.

What it is
An extract derived from the bark of Myrica cerifera, also known as southern wax myrtle or bayberry. It contains tannins and flavonoids that give it astringent and antioxidant properties.
How it works
The tannins in bayberry bark extract can bind to proteins in the skin's surface, creating a mild tightening effect that temporarily reduces the appearance of pores and controls shine. Its flavonoids may help calm minor irritation and provide antioxidant protection against environmental stressors.
Pros
Gentle astringent
Helps tighten pores and control oil without the harshness of alcohol-based astringents, making it suitable for daily use on oily skin.
Soothing potential
Contains flavonoids that may calm minor redness and irritation, offering a dual benefit for blemish-prone skin.
Cons and cautions
Limited human evidence
Most research is lab-based; there are few clinical studies confirming its effectiveness on human skin, so results may vary.
Potential drying effect
Because of its astringent tannins, it can be drying if used too frequently or in high concentrations, especially for dry or sensitive skin types.
Best for
- People with oily or combination skin
- Those looking for a gentle astringent to minimize pores
Use caution if
- Individuals with very dry or compromised skin barriers
- Anyone allergic to plants in the Myricaceae family
Usage tips
Safety summary
