What it is

An extract derived from the bark of the Juliana tree (Juliana adstringens), a plant native to parts of Asia. The bark is dried and processed to create a concentrated liquid used in cosmetics.

How it works

The extract contains natural tannins and polyphenols that have a mild astringent effect. When applied to the skin, these compounds cause a slight tightening of the skin's surface, which can temporarily reduce the appearance of pores and help control excess oil.

Pros

Gentle astringent

Provides a mild tightening effect without the harshness of alcohol-based astringents, making it suitable for daily use on oily skin.

Natural origin

Derived from a plant source, appealing to those seeking botanical alternatives in their skincare routine.

Cons and cautions

Limited research

There are very few peer-reviewed studies on Juliana bark extract specifically, so its benefits are mostly based on traditional use and anecdotal reports.

Potential for dryness

Overuse or use on already dry skin can lead to tightness or flakiness, as astringents can strip natural oils.

Best for

  • People with oily or combination skin looking for a gentle astringent
  • Those who prefer natural, plant-based skincare ingredients

Use caution if

  • Individuals with very dry or sensitive skin who may find astringents too drying
  • Anyone with known allergies to plants in the same family

Usage tips

Use in a toner or mist after cleansing, focusing on the T-zone if you have oily skin.
Start with once daily to see how your skin reacts, then increase to twice daily if needed.
Always follow with a moisturizer to maintain skin hydration balance.

Safety summary

Juliana bark extract is considered safe for topical use in cosmetics at typical concentrations. There are no known serious safety concerns, but as with any botanical, patch testing is recommended for those with sensitive skin.
