The scientific approach anti-aging care is based on powerful and clinically proven active ingredientsIn particular, from the age of 40, the epidermis requires particular reinforcement of its youth capital.
  
  Essential anti-aging active ingredients
  Retinol, derived from vitamin A, stimulates cell renewal and encourages collagen production. However, it can cause undesirable side effects if not properly controlled in the formula.
  In addition, vitamin C, a powerful antioxidant, combats dull complexions and pigment spots. Hyaluronic acid, meanwhile, retains up to 1000 times its weight in water, providing optimal hydration.
  Amino acids, peptides and many other active ingredients derived from biotechnology are highly sought after in facial care for their anti-oxidant effect and thus allow the treatment to be as effective as possible, particularly in the case of repeated and rigorous use of day and night creams. 
  Face serums being more concentrated, they can boost the treatment for a more visible effect and with more tangible results in the long term.
  
  Optimal product combinations
  The synergy between the active ingredients amplifies their effectiveness. Thus, the combination of 15% pure vitamin C with 1% vitamin E and 0.5% ferulic acid reduces oxidative damage by up to 41%. For a complete action, the Double Serum combined with Multi-Active creams offers a real rejuvenating cure.
  
  Recommended frequency of use
  Introducing active ingredients requires a gradual approach. For retinol, it is recommended to start with one to two weekly applications. Vitamin C serums can be used daily, their effectiveness remaining for 72 hours after absorption. For normal to dry skin, the serum can be applied morning and evening, while oily skin will prefer nighttime use.
  
  Sun protection becomes essential, especially when using retinol which sensitizes the skin to UV rays. In addition, the use of a corrective serum enriched with highly concentrated hyaluronic acid (like those of L'ALPAGE Suisse) can improve skin radiance by 10% and visibly fill fine lines by 15-20% after 8-12 weeks.
