Absorption describes how well a substance penetrates your skin. Here we measure absorption in terms of its rate of penetration into your skin. How fast did it absorb? Some products don't absorb well, and instead "sit" on top of skin forming a film, which can range from light to heavy. If you still have a layer of product sitting on top of your skin, the rate would be considered Very Slow.

Sometimes a product leaves a residue on the skin after it is applied - a film or a layer of product. Often the residue feels greasy, particularly with heavy moisturizers that contain a high amount of lipids. If your product does have residue, how greasy is it?

Users report improvements in skin texture, including diminished wrinkles and brown spots. Studies confirm that tretinoin's natural anti-aging components work synergistically to promote overall
skin clarity and inspire a youthful, healthy glow. Skin cells contain receptors that help regulate how the cell functions. As people age, their cells behave more erratically. But consistent use
of this product helps normalize the cells. Tretinoin (retin-a) can improve skin texture and fade dark spots and freckles because it causes skin cells to turn over more rapidly. It shrinks
dilated pores and improves cell turnover within the pores so they are less likely to clog and become blackheads and whiteheads. Collagen is what gives skin its natural structure, firmness and
elasticity. Repeated sun exposure breaks down collagen and, with age, cells produce less and less collagen to repair the damage. Skin wrinkles, sags and loses fullness. This product also helps
to boost collagen.
