Neem soap is made from the oil of the neem tree. In India, 80% of all neem oil is used for making soap.
The neem oil is the main ingredient of neem oil soap. It's not just an additive as essential oils are (think lavender or tea tree). Neem oil does form the basis of the soap.
Neem oil soap is the most popular form of utilizing the many benefits of neem oil.
Neem oil has insecticidal properties, is antibacterial and antifungal, soothing and moisturising... Neem oil soap is a real treat for the skin, even for healthy skin. But skin problems are where it shines.
Here are just some skin conditions where people have used neem soaps for centuries and with great results. Follow the links to find out more.
But neem soap does also have draw backs, and some of them depend on how the soap has been made.
The neem oil content in neem soap varies. (Some manufacturers may use mainly cheap ingredients and just add some token neem oil. So don't buy just any soap that says "neem" somewhere on the label...)
To get the maximum benefit look for "maximum strength". 20% neem oil content is good. 30%-40% is about as high as you can go.
Soaps with somewhat less neem oil will still be beneficial. Some soaps also have neem leaf extract added. Both neem oil and neem leaf are great ingredients for any skin care products. In fact, a soap that contains both would be excellent!
As I mention on many other pages on this site, the best neem oil is organic, cold pressed oil. The alternative to cold pressing is solvent extraction.
Heat and processing destroy some of the ingredients in neem oil. But cold pressing is more difficult and more expensive...
That's why a lot of the neem oil used in soap making has been extracted with solvents. And it may contain traces of those solvents.
Like many chemicals, those solvents can cause allergies and other reactions in people. People may then blame neem oil, but as so often when people show sensitivities to skin products, it's one of the unpronouncable chemicals that's also in the bottle...
(If someone makes a quality handcrafted neem oil soap they most likely use quality ingredients. So will most people who specialise in quality neem products. This is more of a risk if you buy a cheap, mass produced soap...)
Anyway, most people will be just fine, despite those traces. Just keep that in mind when you buy or try neem soap or any purportedly "natural" or "herbal" skin product, especially if you do so because of an existing skin problem like eczema or psoriasis.
If you do get a reaction, it's not necessarily the herb that's to blame. Do find out what else is in the product, or in the case of neem soap, what neem oil has been used and where it came from.
One other draw back that I already talked about on the page about the use of neem soap for acne is that any soap can dry the skin. It depends on the ratio of the oil to the other ingredients.
It may help you to understand this better if you read through the page about making neem oil soap. Again, the lovingly handcrafted soaps are usually rich, mild and even moisturising. It's the cheap ones where you want to be a bit careful.
And last but not least, there is of course the smell... Neem oil does not smell nice! Most neem companies that make soap also add essential oils to mask the smell of neem. Depending on how sensitive your nose is you may still be able to detect the neem smell when using the soap.
With my sensitive nose I can pick it anywhere, but I don't mind it much. I use neem in so many areas of my life that I got used to it. Still, it isn't the kind of smell a girl wants to wear...
Luckily the smell does not linger after rinsing the neem oil soap off and drying yourself.
So if you want to do your skin some good, try neem soap!
