Serums are designed to be quickly absorbed and are formulated to penetrate to the deeper cells. Creams are designed to provide moisture and nutrients to the upper cells and intracellular layers (like bricks and the mortar between the bricks) while leaving a layer of protective moisture on the surface to prevent dehydration during the night.
Vitamin A&C Serum is a highly unique formula because it combines two of the most powerful vitamins. Vitamin A is the work horse -it helps reduce the appearance of wrinkles and fine lines while the Vitamin C addresses the damage caused by free radicals.
The Night Cream provides shea butter and Ceramide 2 to provide hydration and moisturization which is essential for proper cell turnover. For those who may not be familiar with Ceramide 2, it is a human identical Ceramide, readily able to be utilized by the skin and actually increases the absorption of other ingredients.

Yes, there are other forms of Ceramides, such as Ceramide 1, 7, & 8 - however Ceramide 2 is used in skincare products because it is the only human identical Ceramide and therefore the skin easily absorbs it. The only Ceramide that you'll find in the night cream is Ceramide 2.

Many of the things that you have probably heard about the skin’s health and appearance are misleading. For example, most sources say that collagens are a primary component of the skin, but they are not a primary component of the epidermis, which is the part that we see. It is a primary component of the dermis, which lies between the epidermis and the subcutaneous tissue. Depending on which area of the body you are looking at, there are either four or five layers of the epidermis. The Vitamin A that is used in the Vitamin A & C serum absorbs through a full five layers of the epidermis.
Vitamin A and Ceramides by ML
How far or how deep does this particular form of vitamin A reach in the skins layers? I'm also curious about the ceramides used in this moisturizer. Are there are more forms of ceramides, other then the one mentioned?
