However, in one study, where the lipids obtained form the skin of healthy controls and dogs with acne were evaluated, it was found that the lipids obtained from the acne lesions, such as free sterols, fatty acids, and ceramides, are characteristic
epidermal lipids and that sebaceous gland contribution is minimal.
They moisturize by replenishing
epidermal lipids, then allowing the skin's barrier function to do its job — a key part of which is regulating the skin's water content.
Niacinamide improves
the epidermal lipid barrier, protects the skin from infrared light from UV rays, decreases oil overproduction, diminishes redness, addresses hyperpigmentation, and finally, minimizes the appearance of lines and wrinkles by increasing the frequency of cell turnover.
Atopic dogs have defective
epidermal lipid barriers in their skin.
Firstly, 27 nutritional components were screened in vitro for their ability to up - regulate
epidermal lipid synthesis, using cultured canine keratinocytes (Watson et al. 2006).

We observe that protein isoforms expressed from W01A8.1 are cytoplasmic proteins, residing predominantly on membranous structures of enterocytes and
epidermal cells that have the characteristics of
lipid droplets.
The translational fusion constructs resulted in high levels of cytoplasmic proteins present in intestinal and

lipid droplets.
Similarly,
