How do I choose which The Ordinary Vitamin C to use?

  1. If you’re new to skincare, I would advise starting with one of the derivatives, like Ascorbyl Glucoside or Tetraisopalmitate, because they are more gentle than the others, and the only conflict is Niacinamide.
  2. You may choose a particular vitamin based on its solution. If you already use oil in your routine, you may wish to go for a water-based product like Ascorbyl Glucoside, or if you have water-based products in your routine, you may choose anhydrous solutions or suspensions.
  3. Check your current routine to see which ones will not conflict with your current products. The derivatives only conflict with Niacinamide, whereas the ELAA / LAA have many conflicts.
  4. When do you want to use vitamin C? In the morning or evening? Check which ones are best used AM/PM.
  5. You may choose which vitamin C to buy based on price. The L-Ascorbic Acid Powder is the cheapest.

2. Is it ok to mix The Ordinary L-Ascorbic Acid Powder with The Ordinary Alpha Arbutin. Yes, you may. It’s a great combination.

4. Can I mix L’Ascorbic Acid Powder with The Ordinary Hyaluronic Acid serum? Yes, you may.

5. The Ordinary advises using The Ordinary 23% as the last step as it’s a suspension. What does this actually mean? A suspension means the active is not dissolved and is suspended instead for maximum stability. We suggest using Suspensions as the final step in a routine as they are thicker than a moisturizer or oil. We hope this helps to clarify 

More FAQs

6. Which of The Ordinary Vitamin Cs would be best for a first-time user? Which Vitamin C is preferred? You may wish to begin with The Ordinary Ascorbyl Glucoside Solution 12%. This is a brightening, water-based serum with a stabilized Vitamin C derivative to visibly target uneven skin tone, dullness, and signs of ageing.

7. Is it okay to combine The Ordinary Ascorbyl Glucoside solution 12% after direct acids (aha or BHA) in the same routine? And if yes, should there be a waiting period between the two as they differ in pH? You may indeed combine both products together. There is no need to wait a certain amount of time between applications. As long as each product is massaged into the skin until absorption, you can apply the next product!

8. Is there a NIOD Vitamin C? Yes, NIOD Ethylated L-Ascorbic Acid 30%.
