What are the side effects of castor oil on skin?
Most people tolerate castor oil on body skin without trouble. The realistic downsides are contact irritation, an allergic reaction in a small number of people, and clogged pores or breakouts when it is used on acne-prone facial skin. It is heavy and slow to absorb, which is what most people notice first.

The three that actually come up
Irritation is the most common: redness, stinging, or itching, usually within a day of applying it to skin that was already compromised. Allergic contact dermatitis is rarer but real, and it looks like a spreading, persistently itchy rash rather than a brief sting. The third is congestion — castor oil is heavy and occlusive, which can contribute to congestion and breakouts on acne-prone facial skin.
What castor oil does not contain
Castor beans contain ricin, and that fact circulates as a reason to avoid the oil. Ricin is water-soluble and stays behind in the pressed bean mash; it is not carried into the pressed oil, and commercial castor oil sold for skin use is not a poisoning risk. The real cautions are the ordinary skincare ones above.
How to lower the odds
Patch-test first: a small amount on your inner forearm, left for 24 hours, watching for redness or itching. Keep it off broken, cracked, or freshly shaved skin, where irritation is far more likely. If you are acne-prone, start on body skin rather than your face, or dilute it in a lighter oil. Stop using it as soon as irritation develops rather than pushing through it, and see a dermatologist about any rash that spreads, blisters, or does not settle within a few days.
