Skin & Nail Care

Skin problems are easy to treat with the wrong product. A fungal rash and an eczema patch can look alike, and a steroid cream that calms eczema can make a fungal infection worse. So each review starts with the condition, then the active ingredient the evidence supports for it, then the product. Strength, base (cream, ointment or liquid) and the length of a course matter as much as the brand.

The hub is grouped into itch, rash and eczema; fungal infections and warts; scars, blisters and cold sores; and skin devices and supplements such as red light masks and collagen. Toenail fungus and warts need weeks to months of steady use, and the reviews say so plainly. See a doctor for a rash that spreads quickly, a mole that changes, or any skin problem with a fever.
