Powered ingredient easy to blend, dissolves easily, no gritty feel, product does however transfer this chemical transdermally and should be thought about prior to mixing as it does effect hormones. Gives skin a quick firm appearance in personal formulations and was a great experimental addition to personal products. The DIY provided on this site is the way to go to try out this product. A little goes a long way... ...»
Hi, Ordered this about 5 weeks ago, so I been waiting to DIY and try the product before I left a review. I mixed Palmitoyl oligopeptide and palmitoyl tetrapeptide-7 Liposome Emulsion, 3/4 tsp, with 3tsps distilled water and 3/4 tsp of rose hip oil. It makes a beautiful light weight serum that I apply at night. You can feel tightening within a few minutes. The tightening subsides in half hour or so and then I apply a moisturiser. Another excellent buy from Bulk Actives. .. ...»

I've been using glucosamine in combination with niacinamide as an addition to my moisturizer to combat dark spots on face and hands. Used twice daily, it does seem to keep them from darkening. Of course, you still need to be religious about using a sunscreen every time you are in the sun. .. ...»

Ascorbic Acid -L (ultra fine powder)

The most common form of topical vitamin c is L-Ascorbic acid. Our L-Ascorbic acid comes as a fine powder. It is used as an antioxidant, for collagen production, in lightening & brightening formulations, to reduce fine lines and wrinkles, and to repair and protect against sun damage.

About L Ascorbic Acid / Vitamin C in DIY Skin Care

L Ascorbic Acid / Vitamin C  (ultra fine powder) is a water soluble (up to 25%) antioxidant that gives all the benefits of Vitamin C which include the ability to promote collagen synthesis, resulting in skin that is firmer, stronger and suppler. Ascorbic Acid is a very powerful antioxidant that not only combats the effects of aging on the skin but also reverses them, and ensures the return of a youthful, firm and supple skin that has a more even tone. Ascorbic Acid -L (ultra fine powder) can also be used in a silicone base which is a bit more stable than the aqueous formulation.

Ascorbic Acid (Vitamin C) has been applied on the skin for rejuvenation for many many years since it anti-aging and its ability to reverse the effects of aging such as fine lines, wrinkles and rough texture were discovered.

Although the body gets its Vitamin C from the foods that we ingest, and fruits and vegetables such as broccoli, Brussels sprouts, papaya and guava are rich sources of Vitamin C, it doesn’t transport very well to places like the skin because it is water soluble and thus gets excreted very quickly. Vitamin C is also a very unstable antioxidant that changes and loses potency quite quickly when in the presence of heat, light and oxygen. Thus topical applications that can be applied directly to the pot of the skin that needs the Vitamin C is the most efficient way of getting this valuable product into the skin.

Once it gets under the skin Vitamin C is good at rebuilding collagen which the fiber that forms skin and whose loss, as we age and as a result of photodamage, results in skin that is sagging, wrinkled and rough-textured. Synthesis of collagen revitalizes the skin, bringing back not just its structure and firmness but also the even tone and smoothness and luster.

Vitamin C is also good at combating free radicals which are unpaired electrons that can cause havoc in the cell structures of the skin by attaching themselves to and causing changes in the structures are well as the DNA of various components of the skin, especially the collagen. Vitamin C is able to mop up these free radicals and stop the chain reactions that they initiate which also goes a long way in refreshing the skin and ensuring that the effects of aging on the skin are no longer visible or felt.

Another important function of Vitamin C as an antioxidant is the fact that it works well when combined with other antioxidants. It has particularly synergistic effect when combined with Vitamin E. Combining the two of them ensures that the anti0-aging benefits are increased to more than four times what they would be with the use of either of the antioxidants on its own. This is because Vitamin C comes to the aid of oxidized Vitamin E and regenerates it, ensuring an improved battling of photoaging by the two products.

Vitamin C has also been known tom work well when combined with other antioxidants such as the polyphenols, particularly those found in red and green teas.
