The product has a strong tar smell — is that normal, and does it linger?

Yes, the strong, smoky, resinous smell is completely normal — it comes directly from the birch tar, which is the main active ingredient. No perfume or fragrance is added to mask it. Birch tar is produced by dry distillation of birch bark, and its distinctive odor is part of what makes it recognizable in traditional Eastern European skin preparations.

The scent is most noticeable right after application and while the product sits on the skin surface. Because the balsam-cream texture is somewhat occlusive, the smell can linger for a few hours, especially in warm conditions or on areas with less airflow (like the scalp under hair). On the face or body, it usually fades as the product absorbs and as you move through the day.

If the smell bothers you, try applying it in the evening so it has overnight to settle. On the scalp, applying it 30–60 minutes before washing your hair can give the active time to work while limiting how long you notice the scent. On the body, wearing loose, breathable clothing over the area helps. Avoid layering heavily scented products on top, as the combination can be more noticeable than the tar alone.

The odor does not indicate spoilage. Store the tube tightly closed at room temperature, away from direct sunlight. If the smell changes to something rancid or sour, or if the texture separates, discard the product.
