As long as you exercise caution, using black castor oil on your lashes and brows is safe. Please avoid getting it in your eyes. And once more, there is no guarantee that applying black castor oil will make your hair grow faster, but it can be an excellent lash conditioning serum. Recently, our ophthalmologist noted that "castor oil hydrates your eyelashes and can make them appear thicker and have more sheen." Consequently, by preventing lash breakage, it might encourage stronger development. Nooren Okwara, MD, from the dermatology unit, advises consumers to keep in mind that castor oil has a reputation for blocking pores. Because the skin around your brows and eyes is thin and prone to clogging, castor oil can exacerbate milia, blackheads, and acne. It can also irritate the skin in sensitive zones. The best course of action is to continue slowly. And it's never a bad idea to conduct a patch test on your neck. Otherwise, check in with your dermatologist before you try it out on your face, as that applies to all skin types, not just those with oily or acne-prone skin.
