1. L-Ascorbic Acid (AA) is vitamin C in its purest form. This unstable, water-soluble antioxidant seems to be the key to benefiting from the nutrient's skin-rejuvenating powers. It is powerful. But it oxidizes very easily. When it oxidizes, it turns yellow or orange and looses its effectiveness. 

2. Also important to ascorbic acid's effectiveness is its pH level. The lower the pH level of AA, the more stable, permeable and, therefore, effective it is. When its pH level is too high, it oxidizes, degrades and becomes inactive - or sometimes even a harbor for dangerous free radical formation.But if the PH level is too low, it is more likely to cause irritation on your skin.

3. What can be frustrating when shopping for the perfect vitamin C serum is the fact that the ideal, potent formula sometimes tends to irritate the skin. Still, there is a solution: using a topical based product with no water will be less irritating since most of the inflammation is caused by hydrogen ions generated by acid disassociating in water. Joyal Beauty Super Brightening Vitamin C Serum is NOT water-based formula. It is liquid texture but it is organic aloe and herbal infusion based with less irritation and more soothing functions. 

4. Ascorbic acid is certainly a tricky substance in terms of stabilization and absorption. And sometimes, even if you do find a formula without water, it might still cause redness or other signs of irritation. Joyal Beauty Vitamin C Serum use SAP to avoid such side effects of AA. 

5. Luckily, there are other options to explore for those seeking the advantages vitamin C has to offer. Synthesized vitamin C derivatives, including ascorbyl palmitate, magnesium ascorbyl phosphate, ascorbyl tetra-isopalmitoyl, tetrahexyldecyl ascorbate, and sodium ascorbyl phosphate (SAP) are more stable and less irritating than ascorbic acid (AA). 

6. Ascorbyl palmitate (AP) is a vitamin C ester, which means that it has been esterified to a fatty acid. It is fat soluble as opposed to the water-soluble ascorbic acid, which may hinder its ability to penetrate skin. Also, ascorbyl palmitate produces different short and long-term effects compared with ascorbic acid.

7.Magnesium ascorbyl phosphate (MAP) is similar to ascorbic acid in that it is water-soluble. However, it also has what AA lacks: a gentle effect on skin, efficacy in lower concentrations, and stability at a neutral pH. In one study, researchers discovered that it was statistically more effective than ascorbyl tetra-isopalmitoyl in free radical reduction, although less so than AA. However, it does seem to better quench the deeper layers of skin than ascorbic acid.

8. Ascorbyl tetra-isopalmitoyl (ATIP) is a vitamin C derivative. It is stable, due to being fat soluble and less irritating than ascorbyl acid. There is a 2006 study that concluded that it can suppress UV-induced skin pigmentation at a 3% dose. Tetrahexyldecyl ascorbate plays nice with vitamins A and E and UV filters. One study published in Dermatologic Surgery in 2002 showed that a topical formulation combining 10% vitamin C and 7% tetrahexyldecyl ascorbate improved hydration and collagen synthesis in the skin and resulted in "clinically visible and statistically significant improvement in wrinkling" after 12 weeks. A 2009 study claims that it can actually prevent UV damage occurring.However, ATIP seems to be a poor performer when it comes to penetrating skin.

9. Sodium ascorbyl phosphate (SAP)(Joyal Beauty Super Brightening Vitamin C Serum) is known to promote collagen formation, and its ability to be stabilized for at least 24 months if it is stored in the original sealed containers at 25 degrees Celsius. With SAP form you do not have to keep it at low PH level to remain its stability, so it is less irritating comparing to AA and it can adjust your skin PH level perfectly better than regular toner. It is also being lauded as an effective acne fighter! Ferulic Acid is a potent antioxidant with synergistic interactions with Vitamin C. Its incorporation into a topical solution of vitamin C+E improved chemical stability of the vitamins C+E and doubled photo-protection to solar-simulated irradiation of skin from 4-fold to approximately 8-fold as measured by both erythema and sunburn cell formation.

10. Proper product formulation can extend the stability of a C serum (which is partly why vitamin C products are so expensive), but you also have to take good care of your vitamin c serum by storing it in a cool, dark place and re-sealing it tightly after each application. Dark container with pump is the best packaging of vitamin c serum. Sunlight, heat, air, water, and even time can all destabilize and render ineffective even the best-formulated vitamin C product. Dark container with treatment pump is the best packaging of vitamin c serum. This type of packaging will help extend its stability and keep it fresh.
