Advanced Optimizer Firming facial serum is the best firming treatment!

It acts in synergy with Advanced Optimizer Cream, reinforcing its firming action and increasing its anti-aging action.

Rich in hibiscus peptides which stimulate collagen production, this facial firming serum visibly firms facial skin and smoothes neck wrinkles.

The features appear redrawn, the skin is more toned and smoother, a real tightening serum!

We appreciate its ultra-fluid texture which penetrates the skin instantly.

HOW TO USE:
Clean and remove makeup from your skin daily with a Yon-Ka cleanser. And mist your face with Yon-Ka Lotion.

For maintenance: Morning or evening, on the face and neck, apply Advanced Optimizer Serum (2 to 3 pumps) then Advanced Optimizer Cream.

As an intensive 30-day treatment: Repeat the same application, morning and evening.
