Ingredient review
Maritime Pine Bark Extract
INCI: Pinus Pinaster Bark/Bud Extract
A gentle, plant-derived antioxidant that helps protect skin from environmental stress and may support a more even skin tone.
In plain English
This ingredient comes from the bark and buds of the maritime pine tree, which grows mainly in coastal areas of France. In skincare, it works as an antioxidant, meaning it helps neutralize unstable molecules called free radicals that can damage skin cells. Think of it like a shield for your skin against pollution and UV exposure. It also has soothing properties, so it can calm minor redness or irritation. You'll often find it in anti-aging serums and moisturizers aimed at protecting the skin barrier.

What it is
A natural extract derived from the bark and buds of Pinus pinaster, the maritime pine tree. It is rich in proanthocyanidins, flavonoids, and phenolic acids, which are compounds known for their antioxidant and anti-inflammatory activity.
How it works
The extract donates electrons to neutralize free radicals, preventing them from oxidizing and damaging skin lipids, proteins, and DNA. It also inhibits enzymes involved in inflammation, such as cyclooxygenase, which helps reduce redness and irritation. Additionally, it may support collagen integrity by protecting fibroblasts from oxidative stress.
Pros
Gentle antioxidant protection
Unlike some stronger antioxidants, maritime pine bark extract is well-tolerated even by sensitive skin, making it a good choice for daily protective serums.
Soothing properties
It can help calm minor redness and irritation, which is useful for those with occasional sensitivity or after mild exfoliation.
Cons and cautions
Limited topical research
Most studies on pine bark extract focus on oral supplements. Direct evidence for its benefits when applied to the skin is less robust, so results may vary.
Potential for allergic reaction
Though rare, people with pine allergies may experience contact dermatitis. Always patch test a new product containing this extract.
Best for
- Anyone looking for a gentle antioxidant to protect against pollution and UV damage
- People with sensitive or reactive skin who want soothing benefits
Use caution if
- Individuals with a known allergy to pine or conifer plants
Usage tips
