For an extra beauty boost, add a Biotin injection to your treatment. This water-soluble B vitamin plays a vital role in keratine infrastructure, the basic protein that makes up our hair, skin and nails. Biotin may promote hair and nail growth, as well as cellular turnover which leads to glowing skin. A Biotin injection can be added to any of Zen’s IV infusions. This is an Aesthetic Grade Vitamin Booster Shot with a lower concentration (mcg/ml) and dosage than the medical Vitamin Booster Shots.
