Optase TTO Lid Wipes contain a unique and gentle formulation of tea tree oil and hyaluronic acid. Tea tree oil is a natural ingredient with known anti-bacterial properties. Hyaluronic acid moisturises and soothes the eyelids, and can help improve eyelid elasticity. In addition to hyaluronic acid, the lid wipes contain chamomile and aloe vera for further hydration and to soothe sore eyelids. Optase TTO are preservative free, and so are ideal for daily eyelid hygiene. They have a textured wipe which are ideal for gentle cleansing and assist in the removal of dandruff from the eyelids.
