Castor oil is often associated with hair growth or eyelash care, but its benefits go far beyond that. In natural cosmetics, it is also recognized as an excellent treatment for strengthening nails and deeply nourishing the skin.
But is it really effective? And how can you use it properly without a greasy or comedogenic effect?
In this article, discover everything you need to know about castor oil for nails and skin, its real benefits, its limitations, and the best ways to incorporate it into your beauty routine.

4. Castor oil for skin: what are the effects?

It softens the skin, especially on areas such as:

5. How to use castor oil on the skin?

Due to its thick texture, it is best mixed with:
- sweet almond oil

- coconut oil
This makes application easier and reduces the greasy feeling.
6. Can it cause breakouts?
Yes, in some cases.
Castor oil can be comedogenic for certain skin types, especially:

It is therefore best to avoid using it pure on the face if you are prone to breakouts.

8. Precautions to consider
Even though it is natural, castor oil requires some precautions:
