For your daily morning routine, and any time your skin needs more freshness and firmness.
TONUS must be applied on freshly cleansed wet skin (use lukewarm water or tonic water spray). Gently rub 1-2 drops of serum on face, neck or neckline areas in circular movements. Wait until the serum is completely absorbed before applying any other skincare product or makeup.

If you are about to use a day cream, a night cream, or any other cosmetic product, apply TONUS first.

Thanks to its specific hyaluronic blend, it effectively reaches the upper layer of the epidermis for an instant tightening effect. In addition to that, our core ingredients such as chlorella and aloe vera juice add unparalleled restorative and wound-healing benefits to create a smooth canvas and long-lasting elasticity. The combination of rosehip oil and patchouli help tackle dermatitis, eczema, and rosacea while fading scars and marks.
