About this product

Details

The ultimate serum duo to fill lines, firm, and boost collagen. Use AM and PM to deliver immediate and long-term results for all skin types. 

What's Included:

  • TGF-β Booster: Transforming growth factor serum smooths, hydrates, and firms, while minimizing fine lines.
  • Vita-C Serum: Brightening serum with antioxidants and amino acids balances, brightens, and combats oxidative stress.

About Le Mieux: We only use the best so you can look your best. We’re redefining skincare by disrupting standard water-based formulas and prioritizing high concentrations of actives—no fillers, just purposeful ingredients that nourish deeply and promote your healthiest, best-looking skin yet.

How to use

After cleansing and toning, apply TGF-β Booster to face, neck, and chest. Follow with a layer of Vita-C Serum. Be sure to wear sun protection during the day.
