There are often reports that relate to allergic reactions, such as:

  • skin rashes
  • swelling
  • itching

Anyone who experiences an allergic reaction to castor oil should seek medical attention immediately.

Skin irritation and the development of rashes are the most commonly reported side effects.


Using castor oil is a useful and inexpensive way to promote skin health, and it may have particular benefits for facial skin.

However, much of the evidence underlying these benefits is yet to be deemed conclusive, and a greater degree of scientific research will be required to determine the full benefits of castor oil.

This oil is relatively safe, but it can cause some side effects that should be considered when deciding whether to use castor oil on the face and skin.
