What Is Lysimachia Clethroides Extract?
Lysimachia Clethroides Extract is a plant-derived ingredient obtained from the whole Lysimachia clethroides, a flowering herb in the primrose family. Traditionally valued in East Asia as a folk remedy for skin discomfort, it eventually caught the attention of cosmetic formulators for its soothing and conditioning qualities. The plant is harvested, air-dried, then soaked in a food-grade solvent such as glycerin or ethanol to pull out its water-soluble sugars, flavonoids and small amounts of natural oils. After filtration the liquid is concentrated or blended straight into a carrier solution, creating a stable extract suitable for skincare. You will most often spot it in face masks, hydrating toners, lightweight moisturizers, after-sun gels and anti-aging serums where gentle skin-nurturing ingredients are a priority.
Lysimachia Clethroides Extract’s Cosmetic Benefits/Uses
Lysimachia Clethroides Extract is prized in formulations for one key role: skin conditioning. By helping skin retain water, smoothing rough patches and supporting a balanced feel, it leaves the complexion softer, more supple and better prepared to handle other active ingredients.
Who Can Use Lysimachia Clethroides Extract
Lysimachia Clethroides Extract is gentle enough for most skin types. Dry and mature skin benefit from its water-binding sugars, while oily or combination complexions appreciate its light texture that does not add extra grease. Sensitive or reactive skin usually tolerates it well thanks to the absence of harsh acids or fragrance components, though anyone with a known allergy to primrose family plants should proceed with caution.
The extract is plant sourced and typically processed in vegetable glycerin or food-grade ethanol, making it suitable for vegans and vegetarians. No animal-derived adjuvants are normally involved during standard cosmetic production.
No specific data link Lysimachia Clethroides Extract with problems in pregnancy or breastfeeding when used topically. Still, this is not medical advice and anyone who is pregnant or nursing should check with a doctor before adding new skincare products.
The ingredient is not known to increase photosensitivity, so it should not raise the risk of sunburn beyond normal exposure. Standard daytime sunscreen use remains important for overall skin health.
Potential Side Effects/Adverse Reactions
Responses to topical Lysimachia Clethroides Extract vary from person to person. The points below outline potential side effects, yet most users will never experience them when the ingredient is formulated and used correctly.
- Allergic contact dermatitis – rare itching, redness or rash in individuals sensitive to plants in the Primulaceae family

If irritation or any adverse reaction occurs stop use immediately and consult a healthcare professional.
Comedogenic Rating
Rating: 0–1 out of 5. Lysimachia Clethroides Extract is mostly made up of water-soluble sugars and light flavonoids with only trace oil content, so it does not form a heavy film or clog pores. This makes it a safe pick for people who are prone to acne or breakouts.
Any clogging risk usually depends on the richer emollients or waxes in the finished product rather than on the extract itself.
Summary
Lysimachia Clethroides Extract conditions skin by binding water, softening rough areas and supporting a balanced surface thanks to its natural sugars and soothing flavonoids. While it is not yet a household name it is gaining traction in hydrating toners, sheet masks and calming gels because it plays well with other actives and remains gentle on most skin types.
Overall it is considered very safe with only rare allergy concerns. Even so it is always smart to patch test a new product before full use to be sure your skin is happy with the formula.
