Ingredient review
Pine Tar Oil
INCI: Pinus Palustris Tar Oil
Pine tar oil is a traditional ingredient known for soothing irritated skin and scalp, but its strong odor and potential for irritation mean it's best used in targeted, low-concentration formulas.
In plain English
Pine tar oil is a dark, sticky oil made by heating pine wood. It has a strong smoky smell and has been used for centuries in soaps and ointments to help calm itchy, flaky, or irritated skin. Think of it as a natural, old-school remedy that can be effective but isn't for everyone due to its scent and potential to cause irritation if used too strong.

What it is
Pine tar oil is a byproduct of the destructive distillation of pine wood, primarily from the Pinus palustris tree. It contains a complex mixture of phenols, hydrocarbons, and resins that give it its characteristic odor and skin-soothing properties.
How it works
In skincare, pine tar oil works by providing a mild antimicrobial and anti-inflammatory effect on the skin's surface. It helps reduce the presence of certain bacteria and fungi, and its phenolic compounds can help calm redness and itching. It also acts as a gentle keratolytic, meaning it can help soften and shed dead skin cells, which is why it's often used in products for flaky scalp conditions.
Pros
Traditional soothing ingredient
Pine tar oil has been used for generations to calm itchy, flaky skin and scalp, making it a trusted option for those who prefer time-tested remedies.
Mild antimicrobial action
Its natural phenolic compounds can help reduce surface bacteria and fungi, which may support a healthier skin environment without harsh chemicals.
Cons and cautions
Strong, unpleasant odor
The smoky, tarry smell of pine tar oil is very noticeable and can linger on skin and hair, which may be off-putting in daily use.
Potential for skin irritation
At higher concentrations or on sensitive skin, pine tar oil can cause redness, stinging, or allergic reactions, so patch testing is essential.
Best for
- People with occasional scalp flakiness or itchiness
- Those looking for a traditional, natural ingredient for soothing minor skin irritations
Use caution if
- People with sensitive or easily irritated skin
- Those with acne-prone skin (due to comedogenic potential)
- Pregnant or nursing individuals (due to lack of safety data)
Usage tips
Safety summary
Pine tar oil is considered safe for topical use in low concentrations, but it can cause skin irritation, allergic reactions, and is potentially comedogenic. It should be avoided on broken skin and during pregnancy due to insufficient safety data. Always patch test and use as directed.
Research notes
Research on pine tar oil is limited but suggests it has antimicrobial and anti-inflammatory properties, supporting its traditional use for skin conditions like eczema and psoriasis. Most evidence is anecdotal or from small studies; larger clinical trials are lacking.
Common label clues
- Typical concentration
- 0.5% to 5% in leave-on products; up to 10% in wash-off products
- Regulatory status
- In the US, pine tar oil is generally recognized as safe for use in cosmetics when used as directed, but it is not approved as an active ingredient in over-the-counter drug products for conditions like psoriasis. The EU allows its use in cosmetics with concentration limits for certain applications.
- Common uses
- Soaps, Ointments, Scalp Treatments
- Environmental note
- Pine tar oil is a natural byproduct of wood processing, but its production involves heating wood, which can release volatile organic compounds. Sustainable sourcing from managed forests is recommended.
Good to know
- Pine tar oil is different from birch tar oil, which is sometimes used similarly but has a different chemical profile.
- The strong odor can be reduced by combining with essential oils like lavender or eucalyptus in some formulations.
- It is not the same as pine oil (Pinus sylvestris), which is used in cleaning products and can be more irritating.
