Natural Moisturizing Factor-Enriched Formulations Compared to a Ceramide-Based Cream
Background:
We aimed to investigate the effects of 2 ceramide plus natural moisturizing factor-enriched formulations compared to a ceramide-based cream on skin moisturization.
Methods:
Two double-blinded comparative studies were conducted, which enrolled 35 (n=29 females, n=6 males) and 33 (n=21 females, n=12 males) participants, respectively. Participants applied ceramide plus natural moisturizer cream or ceramide-based cream (study 1) or applied ceramide plus natural moisturizing factor lotion or ceramide-based cream (study 2) to each of their lower legs for 10 days with a 5-day regression period (no moisturizer applied). Skin hydration by corneometry after bilateral application was conducted once daily for each leg in both groups. Results: An increase in corneometer units vs baseline for the ceramide plus natural moisturizing factor-enriched cream and natural moisturizing factor-enriched lotion were greater than the increase vs baseline for the ceramide-based cream at days 10 and 15; with an overall statistical significance in favor of the ceramide plus natural moisturizing factor-enriched formulations at day 10. Conclusions: The marked improvement in skin moisturization following utilization of the ceramide plus natural moisturizing factor-enriched cream and lotion compared to the ceramide-based cream can be attributed to the inherent properties of the natural moisturizing factors. These properties are known to maintain the humectancy and intercellular lipid membrane of the stratum corneum, which directly improves the permeability barrier function of human skin in reducing transepidermal water loss.

Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
