Neem Oil
What Is It?
Neem oil is a potent plant oil extracted from the seeds of the Azadirachta indica tree, native to India. It is widely used in skincare, haircare, and natural pest control due to its antibacterial, antifungal, and insect-repelling properties. Neem oil contains high levels of fatty acids, antioxidants, and bioactive compounds like azadirachtin, making it a powerful ingredient in natural recipes.

PH
Typically has a pH of around 6.0 – 6.5, which is mildly acidic, making it suitable for most skin types.
Absorbency Rate
A moderate absorbency rate. It is slightly thicker and more viscous compared to lighter oils, so it may take a bit longer to absorb into the skin. However, it doesn’t leave a greasy residue and is easily absorbed when massaged in.

Alternative Ingredients/ Substitutions
Tea Tree Oil: Similar antibacterial & antifungal benefits, milder scent
Tamanu Oil: Known for wound healing and scar reduction
Jojoba Oil: A gentler alternative for sensitive skin
Coconut Oil: Lighter and less odourless, but lacks neem’s bioactives.
Best Practices
Dilute before use – always mix with a carrier oil (e.g., coconut, jojoba, or almond oil).
Blend with essential oils (e.g., lavender or peppermint) to mask neem’s strong odour.
Heat gently (if solidified) by placing the container in warm water.
Perform a patch test before applying to sensitive skin.
