Vitamin C can be used in combination with other antioxidants, such as vitamin E (contained in the serum P) SODand ferulic acid, as they work well together againstUV damage and photoaging. It can also be used in combination with other active ingredients to enhance the overall benefits to the skin: for example,there are synergieswith isoflavonesorniacinamideagainst aging signs and dark spots.

HOW OFTEN CAN YOU USE IT

Vitamin C can be used daily in the morning and/or evening.It is always important to test vitamin C out before making it a part of regular skincare because some people may experience stinging, itching, and dryness after using topical vitamin C. Those with dry or sensitive skin probably should stick with the lowest concentration, i.e. 7%.

DON’T USE IT IF

If you have very sensitive skin or allergies, it is always recommended to test products on a small skin area before using on the face. It can be problematic for those with oily skin. It is recommended to use Vitamin C separately from Retinol, exfoliants such as AHAs and BHAs, other acids, or anti-acne treatments and use them at different times of the day.

ORIGINS OF THE INGREDIENT

The Kakadu plums have the highest concentration of vitamin C. The main sources of vitamin C are fruits especially acerola cherry, citrus fruits, kiwi, guava, and vegetables, such as red peppers, tomatoes, kale, and broccoli. The discovery of Vitamin C dates back to the 16th century when sailors were found to be suffering from a disease known as scurvy. This disease was later discovered to be caused by a deficiency of Vitamin C, and it was eventually discovered that citrus fruits could prevent and cure it. The first synthetic Vitamin C was produced in 1933, and the use of Vitamin C in skincare began in the 1970s.

Both forms are mirror images of the same molecular structure. Its structure is related to glucose.Vitamin Cis a white crystalline powder.

MECHANISM OF ACTION

Vitamin C is very important for the formation of collagen, one ofthe proteinsthat give skinfirmness.Vitamin C is necessary for the proper processing of collagen and helps keep it from breaking down. It also helps activate cells that make new collagen.Vitamin C is considered agooddepigmenting agent and is generally used as an adjuvant against brow spots and patches.

To maintain its effectiveness, it is important to use Vitamin C products in airtight and opaquecontainers and to store them in a cool, dark place. It’s really challenging to maintain its stability. It is the ideal candidate for a freshly prepared serum,whichisthe best alternativeavailableto avoidboth complex formulationswithchemical stabilizers and potential irritation caused byacidic pH(stability pH level is <4.0).Once added in the serum, its stability is preserved until the end of the bottle.
