Is castor oil good for under eyes?
Yes — castor oil works well as a moisturizer under the eyes, where skin is thinner and drier than the rest of the face, so a heavy, occlusive layer can leave it looking smoother. Use only a small amount on the orbital bone, not the lash line, since it can cause puffiness or milia in some people.
Why an occlusive oil helps there
Skin under the eyes is thinner and produces less of its own oil than skin elsewhere on the face, which is part of why it looks dry and fine-lined first. Castor oil is thick and slow to absorb, and here it behaves the way it does everywhere else on the body: a heavy film that slows how fast moisture leaves the skin rather than contributing much of its own. On thin, dry skin, that slower moisture loss can make the area look smoother while it is on.
Puffiness and milia are the two things to watch for
A heavy layer applied too close to the eye, or too much of it, can look puffier by morning in some people, since the skin there already retains fluid easily. Milia — small, hard white bumps — are keratin trapped just under the surface when skin does not shed it normally, and a heavy occlusive layer can make that more likely; the under-eye area is a common place for them to appear. Neither is dangerous, but both are reasons to use less rather than more.
Keep it on the orbital bone, not the lash line
Apply a very small amount — less than you would use on the rest of your face — along the orbital bone, well below the lash line, and pat rather than rub it in. Oil that migrates into the eye blurs vision for a while and is unpleasant, and it is not a sterile eye product — that is the main reason to be conservative with placement here rather than with how often you use it.
