by Wendy Kim on Jul 10, 2020

If you have been keeping up with Wishtrend for a while now, you would be very much familiar with Vitamin C serum here on Wishtrend. There is the Dear, Klairs Freshly Juiced Vitamin Drop and there is the By Wishtrend Pure Vitamin C 21.5% Advanced Serum. These two vitamin c serums you can find at Wishtrend have been the 'best-sellers' for the past years. The Vitamin Drop by Dear, Klairs has been attracting those with sensitive skin while the Pure Vitamin C 21.5% Advanced Serum has been loved by those who expect faster results in fading acne pigmentation and improving dull skin. Despite these two different vitamin c serums that have been curated to different skin types and customers, there were growing requests to come up with a vitamin c serum that meets between the Vitamin Drop and the Advanced Serum. By Wishtrend answered with the introduction of the Pure Vitamin C 15% with Ferulic Acid in 2020. Now the question is, how are the two Vitamin C serums from By Wishtrend different?

1. Battle of the Best: Pure Vitamin C 21.5% vs 15% with Ferulic Acid

Both Pure Vitamin C 21.5% Advanced Serum and the Pure Vitamin C 15% with Ferulic comes in 30ml sized ampoule bottle. Just by the name of the product and the look of the color coordination of the bottles, you would instantly realize that the 15% Ferulic Acid is a milder and a more gentle version of the 21.5% Advanced Serum. But, enough of 'judging book by its cover', let's see how these two are really different and which one will suit your skin better.

2. Pure Vitamin C 15% with Ferulic Acid: High potency, low-irritation

Recommended if... - you are a beginner to high potency vitamin c serum- you have acne prone skin - you have dull skin - you have dry skin To have a better understanding of the 15% Ferulic Acid, we must go back to why this product came about in the first place. As By Wishtrend's 21.5% Advanced Serum has been gaining its momentum thanks to its high potency and effective acne and pigmentation care, there were rising requests for a vitamin serum that works as effective but gentle on sensitive skin and for vitamin c serum beginners. Formulating 15% of ascorbic acid instead of 21.5% and adding 'ferulic acid' to make it a hydrating and still an effective vitamin c serum, it is designed to give less tingling and stinging sensation on the skin. 'High potency, low-irritation' is what best explains the 15% with Ferulic Acid.
