Tomato powder can be added to skincare for its benefits, which include antioxidants from lycopene, improved skin texture, and pore-tightening properties. It is a popular ingredient in handmade soaps, masks and scrubs to help improve skin texture, brighten complexion, and provide antioxidant protection. It can be used in both cold-process and melt-and-pour soaps, often in combination with other ingredients like exfoliating agents.
