Vitamin C, type L-ascorbic acid, ultra-fine, smaller than 45 microns. high purity The most effective compared to other types of vitamin C. Makes the skin look brighter. Helps soften wrinkles Helps stimulate the creation of collagen. and is an antioxidant

Vitamin C, type L-ascorbic acid, should not be mixed directly with water. Because oxidation will occur and cause damage.

Ultra Fine is a powder size not exceeding 45 microns, cut with a laser, making it easily dispersed. Suitable for use in formulas that do not have water as a solvent (Anhydrous) such as Vitamin C Silcone Serum in the Kiehl's formula because it is easier to disperse than normal Ascorbic Acid.

This grade of Vitamin C is used in the product The Ordinary 100% L-Ascorbic Acid Powder.

1. Vitamin C (L-ascorbic acid) (Standard) has normal powder size (smaller than sugar. But bigger than salt) is a product that focuses on saving.

2. Vitamin C (L-ascorbic acid) (Fine) has a small powder size (Fine), with the average size being in the range 200-300 micron

3. Vitamin C (L-ascorbic acid) (Ultra-Fine) has an extra small powder size (Ultra-Fine) with a size smaller than 45 microns being the smallest size.

Vitamin C, any grade of Ascorbic Acid, is not stable. When dissolved in water But it is more effective than Vitamin C in other forms.

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 sides 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 sides 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

It is recommended to use Protec™ OX and Protec™ UV in the formula to help protect Vitamin C from quality deterioration.
