Deep Vita C Capsule Cream — Reddit Reviews
by Medicube
Updated October 3, 2026
Vitamin C and 5% niacinamide for brighter, smoother skin; glassy and scented.
What the community says
A vitamin C cream with 5% niacinamide that people use as a moisturizer-step, not a serum. Redditors like it for a glassy, smoother finish and decent hydration. The big knock is the tacky, greasy feel and the fragrance.
