Kerassentials is a topical oil applied with a dropper to the nails and the skin around them. According to the manufacturer, it blends plant oils, aloe vera and vitamin E to support healthy-looking nails and skin on the feet and hands.
It is a cosmetic-style daily care product, not a medication. Discolored, thickened or painful nails can have several causes and should be checked by a doctor or podiatrist.
