I often recommend use ferulic acid along with vitamin C. These two are a great pair because they help each other be more effective when it comes to protecting against UV damage, giving you more bang for your buck. Ferulic acid also helps stabilize vitamin C, which is a notoriously unstable ingredient and breaks down easily without proper support.“.

People with sensitive skin will benefit from lower percentages and/or gentler formulations of vitamin C to prevent irritation.” In that case, she recommends First Aid Beauty’s 10% Vitamin C Brightening Serum ($50), as It is designed for sensitive skin.
