The Ordinary 100% L-Ascorbic Acid Powder100% L-Ascorbic Acid Powder
Fine 325 Mesh Topical Powder
The format of this formula is a very fine, anhydrous, L-Ascorbic Acid powder and, as such, provides the most direct exposure of extremely high concentrations of Vitamin C topically. With such format, a very strong tingling but non-irritating sensation is expected during the first 1-2 weeks of use until the skin's tolerance to such high exposure is elevated.
* If topical Vitamin C is used as part of skincare, it should be applied at alternate times with EUK 134 or Niacinamide (ideally Vitamin C in the PM and EUK 134/Niacinamide in the AM). Otherwise, EUK 134/Niacinamide can affect the integrity of pure-form Vitamin C (L-Ascorbic Acid).
The Ordinary's portfolio of Vitamin C includes the following formulations:
Vitamin C Suspension 30% in Silicone
Vitamin C Suspension 23% + HA Spheres 2%
Ascorbyl Glucoside Solution 12%
Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F
Magnesium Ascorbyl Phosphate 10%
Ascorbic Acid 8% + Alpha Arbutin 2%
Ethylated Ascorbic Acid 15% Solution
100% L-Ascorbic Acid Powder
Topical Vitamin C offers a wide array of benefits to the skin. However, many forms of Vitamin C and many more formulations of Vitamin C are available commercially with a potential to confuse the audience. We have developed a guide that offers guidance on the formulations of Vitamin C offered under The Ordinary range. It also offers education on Vitamin C itself and on the differences between formulations of Vitamin C at large.
Patch tests are an easy way to help predict if you may experience a negative initial reaction to a new product. It is recommended to perform a patch test before incorporating any new product into your regimen. We have outlined a general method for conducting your own patch test below based on the type of product.
- Apply a small amount of the product onto a clean area of skin on the upper forearm.
- Keep the area dry.
- If the product has a specified duration of use, rinse off after this time has elapsed. Otherwise rinse off after 24 hours.
- If any redness, burning, itching, blistering or irritation is observed at any time throughout the test, do not use the product.
