Neem Leaf Extract
- General Description and Role
- Claim: “Neem Leaf Extract is a potent natural antimicrobial and anti-inflammatory agent derived from the leaves of the neem tree (Azadirachta indica), a fast-growing evergreen native to India and widely used in Ayurvedic medicine for centuries. It’s extensively applied in skincare for its purifying, healing, and protective qualities against bacteria, fungi, and inflammation. The extract is typically obtained through ethanol, water, or ultrasound-assisted extraction methods and is formulated in various topical products, with concentrations varying based on the intended therapeutic effect.”
- Verification: Accurate. Neem leaf extract, sourced from Azadirachta indica, is traditionally and scientifically recognized for its antimicrobial, anti-inflammatory, and healing properties in dermatology, with extraction methods like ethanol and ultrasound yielding bioactive compounds for topical skincare applications.

- Composition and Production
- Claim: “Neem Leaf Extract contains limonoids (e.g., azadirachtin, nimbin, nimbidin, nimbolide, salannin, gedunin), flavonoids (e.g., quercetin, kaempferol, rutin, catechin, myricetin), phenolic compounds (e.g., tannins, gallic acid, epicatechin), terpenoids, alkaloids, glycosides, saponins, steroids (e.g., β-sitosterol), fatty acids (e.g., oleic, linoleic, palmitic), and minerals, with over 135 phytochemicals identified. The exact composition depends on extraction methods, plant maturity, and environmental factors.”
- Verification: Accurate. Neem leaves are rich in limonoids, flavonoids, and phenolics, with composition varying by extraction (e.g., aqueous, ethanolic), supporting its bioactive profile for skincare.

- Skin Type Suitability
- Claim: “Neem Leaf Extract is versatile but works best for oily and acne-prone skin (reduces sebum, clears pores), inflammatory conditions (e.g., eczema, psoriasis), combination skin, normal skin, and sensitive skin in low concentrations. Not ideal for very dry or dehydrated skin due to potential dryness.”
- Verification: Accurate. Neem is beneficial for acne-prone, oily, inflamed, and sensitive skin types through its antimicrobial and soothing effects, but may exacerbate dryness in very dry skin without moisturizers.

- Benefits
- Claim: “Benefits include antimicrobial effects (against bacteria, fungi, viruses), anti-inflammatory (reduces redness, swelling), antioxidant (neutralizes free radicals), wound healing (promotes collagen, tissue regeneration), anti-aging (inhibits melanogenesis, protects from UV), purifying and oil control, antifungal/antiparasitic, and soothing for conditions like psoriasis and eczema.”
- Verification: Accurate. Neem leaf extract provides broad antimicrobial, anti-inflammatory, antioxidant, and wound-healing benefits, supported by in vitro, animal, and limited clinical evidence for dermatological use.
