We offer two serums. 1) The Calendula Facial Serum is a light but moisturizing serum. Infused aloe vera with chamomile and calendula combined with carrot seed extract, primrose oil and msm, it offers protection and healing for those with sensitive skin. It is a great moisturizer for those with acne. 2) The Lightening and Brightening Serum has the same formula as the Calendula Facial Serum with the addition of schisandra berry, narcissus gazzetta, and galanthus to help with reducing spotting. It is a little heavier than the Calendula Facial Serum and is well suited for dryer or older skin.
