What Is Clausena Lansium Leaf Extract?
Clausena Lansium Leaf Extract comes from the leaves of the wampee tree, a citrus relative that grows in South and Southeast Asia. The leaves are rich in natural sugars, flavonoids and light essential oils that attract and hold water. In folk beauty routines the leaves were soaked in water and applied to calm and soften skin, which drew the interest of modern formulators in the early 2000s.
To make the cosmetic-grade extract growers pick mature leaves, dry them then soak them in a safe solvent such as water mixed with a bit of ethanol or glycerin. The liquid is filtered to remove leaf bits, concentrated and standardized so each batch delivers a steady level of skin-friendly compounds.
You will spot Clausena Lansium Leaf Extract in hydrating face masks, everyday moisturizers, after sun gels, lightweight serums, anti aging creams and even soothing hair conditioners where it helps balance moisture without feeling greasy.
Clausena Lansium Leaf Extract’s Cosmetic Benefits/Uses
This plant extract plays two key roles in skin and hair care formulas.
- Humectant: It pulls moisture from the air and holds it on the surface of skin or hair. This helps keep skin looking plump and dewy and reduces the feel of dryness or tightness.
- Skin conditioning: The leaf compounds smooth and soften the outer layer of skin which can improve texture and give a healthier glow.
Who Can Use Clausena Lansium Leaf Extract
Thanks to its lightweight water-binding nature this extract is considered friendly to most skin types including oily, combination, normal and dry skin. Sensitive or highly reactive complexions can usually tolerate it but should be aware that the trace essential oils naturally present in the leaves might trigger redness in a very small number of users.
The ingredient is entirely plant based so it aligns with vegan and vegetarian lifestyles. No animal derivatives or by-products are used in its harvesting or processing.
There is no evidence that topical use poses a risk to women who are pregnant or breastfeeding. That said this is not medical advice and anyone expecting or nursing should show their chosen products to a qualified healthcare provider to be on the safe side.
Clausena Lansium Leaf Extract is not known to increase photosensitivity and can be worn during daytime without raising sun-related concerns. It also layers well with most common actives such as niacinamide or hyaluronic acid making it a flexible addition to many routines.

Comedogenic Rating
Rating: 1 out of 5
Clausena Lansium Leaf Extract is mostly water based and contains only trace levels of lightweight essential oils so it does not leave a heavy film that can block pores. A score of 1 reflects the very low chance of buildup while still allowing for the fact that any botanical ingredient can react differently on individual skin.
Because of this low rating the extract is generally considered suitable for people who are prone to acne or breakouts.
Formulas that pair the extract with rich butters or occlusive oils could raise the overall comedogenicity of the finished product so always look at the full ingredient list if clogged pores are a concern.
Summary
Clausena Lansium Leaf Extract acts mainly as a humectant and a skin conditioning agent. The natural sugars and flavonoids grab water from the air and lock it against the skin surface which boosts hydration while the light oils and plant acids smooth rough patches for a softer feel.
Although not yet a household name the extract is showing up more often in hydrating serums, gel creams and after sun products thanks to its gentle touch and plant based appeal.
Current research and user reports point to a high level of safety with only rare irritation or allergy issues. As with any new skincare ingredient it is wise to do a quick patch test when trying a product that contains Clausena Lansium Leaf Extract especially if you have very sensitive or reactive skin.
