Celimax Retinol Shot & Retinal Shot

Vita-A is Celimax's vitamin A line, and it carries both forms side by side: a Retinol Shot serum and a Retinal Shot booster. The difference between them is one step of conversion — skin turns retinol into retinal, and retinal into the active form, so retinal starts a step closer. Which suits you is decided by concentration and formula, not by the name alone.
