1. Aloe Vera Gel
The Aloe Vera plant has been known to increase collagen levels for ages, and that is why it is so successfully used to heal wounds. This collagen boost can be obtained through topical application, or by taking an Aloe Vera supplement.
The topical application can be made using Aloe Vera based products, or you can even use the plant directly if you prefer to. The latter has properties that stimulate cell growth and regeneration. It will also stimulate the production of collagen in your skin.
