From Alder New York.
Alder New York's Facial Roller is made from black obsidian, a natural crystal formed from rapidly cooling lava. This dual stone facial roller relieves tension, reduces puffiness, and promotes circulation. Use morning and/ or night to improve overall skin health and appearance by stimulating collagen, massaging tense muscles, and promoting lymphatic drainage.
Each roller is unique and may have slight variations due to the organic nature of the stone. Handle with care and press lightly. Clean roller with a damp cloth and/ or rubbing alcohol.
