What Is Lagerstroemia Indica Extract?
Lagerstroemia Indica Extract is a plant-derived ingredient obtained from the whole crepe myrtle shrub, a flowering member of the Lythraceae family that is native to Asia and now grown widely in warm climates. The leaves, stems, flowers and bark contain a mix of bioactive compounds such as ellagic acid, flavonoids, tannins and triterpenes, all of which contribute to its soothing and antioxidant character. Traditional folk practices used crepe myrtle infusions to calm the skin; this laid the groundwork for modern formulators who began adding standardized extracts to cosmetics in the early 2000s when botanical trends surged.
To create the cosmetic-grade extract, the dried plant material is macerated then subjected to a gentle water-or glycerin-based extraction. The liquid is filtered, concentrated and finally preserved into a stable solution or powder that blends easily into modern formulations. You will most commonly spot Lagerstroemia Indica Extract in moisturizers, hydrating serums, sheet masks, after-sun lotions and anti-aging products aimed at maintaining a smooth comfortable complexion.
Lagerstroemia Indica Extract’s Cosmetic Benefits/Uses
This botanical serves a single yet valuable purpose in skincare formulations.
Skin conditioning: the polyphenol-rich extract supports the skin barrier by supplying antioxidants that help neutralize environmental stressors while mild tannins lend a refined feel to the surface. Regular use can promote a softer texture, balanced hydration and an overall healthier appearance, making the ingredient a versatile addition to daily care products.
Who Can Use Lagerstroemia Indica Extract
Lagerstroemia Indica Extract is generally friendly to all skin types. Its light antioxidant profile suits normal, dry, combination and even oily complexions without leaving a greasy film. Those with very sensitive or highly reactive skin may wish to start with lower concentrations since the gentle tannins could feel slightly astringent on compromised barriers.
The extract is plant derived and processed without animal by-products so it is suitable for vegans and vegetarians.
Current research shows no specific risks for pregnant or breastfeeding women when the extract is used topically at cosmetic levels. That said this is not medical advice and anyone who is pregnant or nursing should check with a healthcare professional before adding new products to their routine.
The ingredient is not known to cause photosensitivity and there are no documented interactions with common actives like retinol or vitamin C, making it easy to slot into most skincare line-ups.
Potential Side Effects/Adverse Reactions
Responses to topical Lagerstroemia Indica Extract can vary by individual. The following list covers potential side effects that have been observed or are theoretically possible though most users will not experience them when the ingredient is included at standard cosmetic levels.
- Mild redness or stinging
- Dry or tight feeling if skin is already dehydrated
- Contact dermatitis in individuals allergic to Lythraceae family plants
- Eye irritation if product is applied too close to the lash line
If any uncomfortable reaction occurs discontinue use and consult a medical professional if symptoms persist.
Comedogenic Rating
Rating: 1/5
Lagerstroemia Indica Extract is mostly water soluble and contains minimal heavy oils or waxy constituents that could block pores. Its tannins have a light, slightly astringent feel that can even help reduce surface oil. Because of this low likelihood of clogging follicles, it earns a score of 1 rather than a perfect 0, simply to acknowledge that any botanical with multiple plant compounds could, in theory, trigger congestion for a very small subset of users.
Suitable for acne-prone and breakout-prone skin in the vast majority of cases.
No special cleansing techniques are required beyond normal face washing, and the extract does not interfere with salicylic acid or benzoyl peroxide commonly found in acne treatments.
Summary
Lagerstroemia Indica Extract is used in skincare for one main purpose: skin conditioning. Its blend of polyphenols, ellagic acid and mild tannins helps reinforce the skin barrier, fight everyday oxidative stress and lend a smoother, more hydrated finish.
Despite crepe myrtle’s long history in traditional remedies, the extract is still a niche player in mainstream cosmetics. You will mainly find it in K-beauty formulas, boutique serums and soothing moisturizers rather than in big-box brands.
Topical safety is high, with only rare reports of irritation or allergy. While reactions are unlikely, try a small patch test when introducing any new product that lists Lagerstroemia Indica Extract, just to be cautious.
