Differences between each type of Vitamin C that the company sells:

1. Ethyl Ascorbic Acid : Vitamin C, soluble in water, highly stable, easy to mix, moderately effective. In terms of brightness (whitening)

2. Perfect-C™ (Ascorbyl Tetraisopalmitate) : Vitamin C dissolves in oil. Moderately stable High efficiency both wrinkles (anti-oxidant), radiance (whitening) and softness (collagen level) of the skin

3. Ascorbyl Glucoside (AA2G™, Stable Vitamin C) : Vitamin C is soluble in water and has moderate stability. Has a complex mixing process (pH level must be adjusted appropriately) and is highly effective in brightening (whitening) and wrinkles (anti-oxidant).

4. Vitamin C (L-ascorbic acid) Ultra-Fine , Vitamin C (L-ascorbic acid) Fine : Vitamin C dissolves in water, can dissolve in water very quickly and disperses very well. has low stability There are complicated mixing steps. High efficiency both wrinkles (anti-oxidant), radiance (whitening) and softness (collagen level) of the skin

5. Vitamin C (L-ascorbic acid) : Vitamin C is water soluble and has low stability. There are complicated mixing steps. High efficiency both wrinkles (anti-oxidant), radiance (whitening) and softness (collagen level) of the skin

6. Stabilized Vitamin C (Natural-C Glycol™) Serum : Ready-made vitamin C base, highly stable. But cannot adjust or add other ingredients. Because it will affect the stability of the bass. High efficiency both wrinkles (anti-oxidant), radiance (whitening) and softness (collagen level) of the skin

7. Magnesium Ascorbyl Phosphate (MAP) : Vitamin C, water soluble , highly stable, easy to mix, moderately effective. In terms of brightness (whitening)

8. Sodium Ascorbyl Phosphate (SAP) : Vitamin C, water soluble , highly stable, easy to mix, moderately effective. In terms of brightening (whitening), it is similar to MAP.

9. Vitamin C Ester (Ascorbyl Palmitate) : Oil-soluble vitamin C. Suitable for use as an anti-oxidant in oil formulas. It has little efficiency in other areas. Compared to other forms of Vitamin C
