Advanced Optimizer Facial Firming Serum is the best firming treatment!
It works in synergy with Advanced Optimizer Creme, reinforcing its firming action and multiplying its anti-ageing action.
Rich in hibiscus peptides that stimulate collagen production, this firming serum visibly firms facial skin and smoothes neck wrinkles.
The features appear to be redefined, the skin more toned and smoother - a real tightening serum!
We love its ultra-fluid texture, which penetrates the skin instantly.

"I love how cooling this feels. And I can actually feel my skin firming. I also love the light scent. I love all things Yon-Ka, and this has become my favorite consistent nightly and morning treatment. . I love mixing it with some of the other amazing Yon-ka products such as the vitamin C drops, Excellence Code Mask, Hydra serum 1 or Mask, and the Booster serums."
