What Is Hydrolyzed Comarum Palustre Root/Stem Extract?
Hydrolyzed Comarum Palustre Root/Stem Extract comes from the roots and stems of Comarum palustre, commonly known as marsh cinquefoil, a flowering plant that grows in boggy areas of the Northern Hemisphere. In its natural state the plant has long been valued in folk skin care for its soothing effect on irritated skin. Modern formulators harvest the roots and stems, then subject them to controlled acid or enzymatic hydrolysis. This process breaks down larger proteins and carbohydrates into smaller peptides, amino acids and sugars while keeping many of the plant’s native flavonoids and tannins intact. The result is a water-soluble extract that blends easily into cosmetic bases.
The ingredient reached the beauty market in the early 2000s when brands began looking for plant-derived alternatives to synthetic conditioners. Because the hydrolyzed form is lightweight and compatible with most emulsions it quickly found a place in serums, sheet masks, calming gels, anti-aging creams, moisturizers and after-sun treatments. Its mild nature also makes it suitable for leave-on products aimed at sensitive or redness-prone skin.
Hydrolyzed Comarum Palustre Root/Stem Extract’s Cosmetic Benefits/Uses
This botanical is valued for one primary role in skin care formulations:
Skin conditioning: The small peptides and sugars produced during hydrolysis form a thin, flexible film on the skin that helps trap moisture and smooth rough areas. Flavonoids and tannins add an antioxidant boost, helping to calm the look of redness from environmental stress. Together these actions leave the skin feeling softer, better hydrated and more comfortable throughout the day.
Who Can Use Hydrolyzed Comarum Palustre Root/Stem Extract
This extract is gentle enough for most skin types, including dry, normal, combination, oily and sensitive skin. The lightweight film it forms is breathable and unlikely to clog pores, so acne-prone users can typically enjoy it without worry. The only group that may need extra caution are people with known allergies to plants in the rose family, as cross-reactivity could occur.
Because it is obtained entirely from a plant source and no animal-derived processing aids are normally required, the ingredient is suitable for vegans and vegetarians.
No data suggest specific risks for pregnant or breastfeeding women when the extract is used topically in standard cosmetic concentrations. This is not medical advice; anyone who is expecting or nursing should show the full ingredient list of any product to a qualified healthcare professional before use.
The extract does not increase sensitivity to sunlight, and there are no special timing or layering rules to follow. It can be used morning or night, with or without SPF as your routine requires.

Comedogenic Rating
Rating: 1 (very low)
Hydrolyzed Comarum Palustre Root/Stem Extract is water based and contains mostly small peptides, amino acids and sugars rather than heavy oils or waxes that can block pores. The thin breathable film it forms sits lightly on the skin and rinses away easily, so the chance of pore congestion is minimal. For most people who break out easily this ingredient is considered a safe option, though the overall formula still matters. If the product pairs the extract with richer occlusive agents the finished item could feel heavier than the extract itself.
Summary
Hydrolyzed Comarum Palustre Root/Stem Extract is a plant derived skin-conditioning ingredient that hydrates, softens and calms by laying down a lightweight moisture binding film while delivering antioxidant flavonoids. It earns its keep in formulas aimed at soothing sensitivity or boosting everyday moisture levels.
Although not yet a household name, it has a quiet presence in niche serums, calming gels and sheet masks where brands look for gentle botanical actives. Its vegan origin and broad skin type compatibility add to its appeal.
Current data and practical use show it to be low risk with only rare reports of irritation, mostly in people allergic to the rose family. As with any new skincare ingredient it is wise to patch test a small area first to be sure your skin agrees with it.
