Citric acid and theanine: work well together

Work well together

Use them together in the same routine, applying the citric acid first and the theanine after, for a gentle and balanced glow. The citric acid mildly adjusts your skin while the theanine keeps it feeling calm and hydrated. You can easily adjust by using a gentler strength if your skin feels sensitive.
