Vitamin C Serum vs Powder – Which Is Better?
Vitamin C has been a huge game-changer in my skincare routine. I have tried various serums before and never saw results. However, the first vitamin C serum that made a noticeable difference was the By Wishtrend Pure Vitamin C 21.5% Advanced Serum. Within the first two weeks of use I noticed that my skin was brighter, smoother and acne scars were fading quicker than normal. This proved to me that vitamin C works but it depends on the stability of the formula and potency of ingredients. A couple months ago I decided to introduce The Ordinary 100% L-Ascorbic Acid Powder into my skincare routine. I was curious as it is a pure vitamin c powder that you mix into your serum or moisturiser. The results from using it were noticeable and gave me the same results as the serum. Seeming as both products have been effective, I wondered if one form of vitamin C is better to use than the other?
What is Vitamin C?
In a recent Allure article, dermatologist, Patricia Wexler described vitamin C as “a potent antioxidant that can neutralize free radicals.” Due to its antioxidant properties, “vitamin C aids in your skin's natural regeneration process, which helps your body repair damaged skin cells." As a result it effectively treats uneven skin tone, rough texture, fine lines, acne scars and general dullness. Vitamin C is for all skin types as it can address various skin concerns. “Pure ascorbic acid has consistently been proven to be the most effective at penetrating the skin barrier,” says Wexler. Vitamin C is also known as ascorbic acid and ascorbate.
The By Wishtrend serum contains 21.5% pure vitamin C and The Ordinary powder contains 100% pure ascorbic acid.

Which is better?
I have found that constantly keeping the serum in the fridge to maintain the formula stability can be an inconvenience. If I am traveling it can be hard to keep the bottle refrigerated which can lead to formula oxidising and becoming less potent. Disclaimer: vitamin C serums that are formulated with ferulic acid are more stable so this may not apply to other serums that contain that ingredient.
I don’t have to worry about oxidisation as much with the powder as I make sure not to leave it open and always use the spatula, so the product is not being contaminated by my fingers. It would also be easier to travel with even though it is messier than using a serum.
In conclusion, I would say that the vitamin c powder is better due to its stability and how long it lasts.
