Castor Oil, answered
Is Castor Oil safe during pregnancy?
Yes. Castor Oil is considered safe to use during pregnancy and breastfeeding. As with anything, if you are unsure it is worth a quick word with your doctor or midwife.
Who should avoid Castor Oil?
Approach Castor Oil with care if any of these apply to you: very oily, acne prone, and pore clogging prone. It carries a moderate risk of clogging pores, so acne-prone skin should go carefully.
What concentration of Castor Oil actually works?
Its concentration is rarely printed on the label, so use the ingredient list as your clue: near the top third it is likely doing real work, near the bottom it is more of a sprinkle.
Does it clog pores?
Thick but rates low; common in cleansing oils.
- This rating comes from old lab tests on the isolated ingredient, not the finished product.
- The full formula, how much is used, and your own skin all matter more than one number.
- If you are acne-prone it is worth noticing, not a reason to avoid it on sight.
