INCI: N-Acetyl Glucosamine
Suggested Usage Rate: up to 2%
One of the stressors for skin, especially during aging, is too much UV radiation that may overload an impaired antioxidant system in older and less efficient skin. One study has found that NAG reduces the amount of free radical damage from UV radiation to fibroblasts, in turn preventing the activation of enzymes that break down skin collagen and accelerate skin aging.
Another study shows that NAG increases the rate that skin fibroblasts make hyaluronic acid and collagen, while simultaneously lowering inflammation in skin. The researchers noted that aging fibroblasts exhibited more youthful behavior under the influence of NAG, much less likely to “retire” from useful service.
The researchers concluded that “NAG-induced changes in the skin fibroblasts' properties maybe important for prevention of the age-dependent changes in its structure and function.”
This new research expands the value of NAG for human health beyond its well known role for better digestive integrity. It is clearly a skin anti-aging nutrient.
Shelf Life and Storage Information for Products and Ingredients
Finished products generally don't need to be refrigerated as they are preserved, but you can refrigerate them to extend shelf life. Shelf life is 9 - 12 months
Sample sizes do have a shorter shelf life (generally 3-6 months and items in jars can dry up quicker than this if the lid is not tightened well enough (except our vitamin C serums - use within 90 days).
Please try to keep out of high humidity or heat if possible! Store out of direct light and in dark cabinet if possible also!
Exfoliating Acid products will last 1 year.
The only thing we don't suggest refrigerating is the mandelic or salicylic acid serums as those can crystallize in the refrigerator and not go back to their normal state even if you warm them up.
Additional Items Requiring Refrigeration
Hydrosols - Take out 1/2 oz to 1 oz in a separate spray bottle from your original container and keep the larger bottle in the refrigerator!
Carrier Oils - Generally you can refrigerate ALL carrier oils, they will solidify in some cases. This is FINE all you have to do is take it out warm it up at room temp and it will be liquid again!
There are some oils that have a super long shelf life like coconut oil for instance! That does not need to be refrigerated, but it cannot hurt it either!
Essential Oils - Essential oils are best stored in a cool dark place.
Co2 Oils - These should always be refrigerated.
Butters - We suggest refrigerating our skincare butters. You can take out what you need and keep the rest in the fridge.
Essential oils - These can be refrigerated to increase their shelf life!
Clays - Keep in a dry, dark place (shelf life is at least 2 years)
Herbs - (whole or ground) These should last a good year at least - Keep in a dark, cool and dry location.
Herbal Extracts - [powder] Keep these also in a dark, DRY place. You can keep in the fridge, but make sure the seal is on very tight so you don't get moisture in. [1 year at least].
Herbal Extracts - [liquid] These can be kept in the refrigerator (or a dark DRY place] [3 years at least]
Other Various Raw Ingredients - i.e. Sodium PCA, Honeyquat, Iat Beta Glucan etc will all have a different shelf life (we are working on adding this to the ingredient pages.
