Collagen is in the under layer of the skin called the dermis. The dermis is the backbone of the skin. The dermis is a living structure of the skin and it supports the outer skin called the epidermis. Leather is the dermis of the cow, the cows under layer of skin. Collagen is a structural protein, the foundation for the strength and elasticity of the skin.
We want to maintain, nourish and support the dermis layer of our skin to keep our skin supple, radiant and slow the aging of our skin.
In skin care products, plant-based collagen helps to keep the skin supple and radiant. Most collagen in skin care products is derived from cows until recently and now there is an option of collagen derived from plants. In my opinion, plant-based collagen is superior to bovine (cow) collagen. I use plant-based collagen in my formulations.
The Regenerating and Brightening Serum with Plant Collagen is in the Professional Natural Skin Care Course.
