• Copper tripeptide (0,5%)- plays a vital role in, among other things, collagen synthesis, melanogenesis and the healing process. Copper occurs naturally in human skin, but as we age, the amount of this element decreases, accelerating the ageing process. Copper peptides actively stimulate the synthesis of elastin, collagen and glycosaminoglycans, including hyaluronic acid. They affect all signs of ageing, making the skin firmer and more elastic. They thicken the epidermis, improving its structure, smoothing the complexion, firming and adding elasticity, and reducing the depth and length of wrinkles. Copper tripeptide protects the skin from oxidative damage and reduces excessive pigmentation. It soothes irritation, stimulates natural regeneration processes and rejuvenates.
• Oligopeptide-1 - is a unique peptide known as Epidermal Growth Factor (EGF), which stimulates skin cell growth and strengthens the skin barrier. EGF stimulates the division, growth and differentiation of epidermal cells. It accelerates epidermal regeneration and reduces the adverse effects of oxidative stress, preventing the degradation of collagen and elastin fibres. It stimulates skin regeneration and renewal, improving skin density and counteracting loss of firmness. 
• Copper Lysinate/Prolinate is a complex of copper ions and two amino acids: lysine and proline. By supplying the skin with copper ions, the complex smoothes and improves skin texture. It makes the skin firmer and more elastic. It also has an anti-inflammatory effect and promotes regeneration processes. 
• Amino acid complex - (proline, arginine, threonine, lysine hydrochloride, glutamic acid, glycine, alanine, serine, pyroglutamic acid, sodium lactate, sodium pyroglutamate and betaine) These substances are part of the natural moisturising factor NMF. The complex provides long-lasting hydration, strengthens the skin's natural protective barrier, soothes irritation, smooths and makes the skin supple.

* results confirmed by instrumental tests at an accredited laboratory

Apply a small amount of serum to the face, neck, and décolleté. Apply in the mornings and/or evenings to cleanse and dry skin as needed.

• Do not use Renova CU+ serum in the same skincare routine with AHA and BHA acids, as the copper peptides lose their effectiveness in an acidic pH. To use both active ingredients effectively, use Renova CU+ copper peptide firming serum during the day and cosmetics with acids at night.
• Do not use Renova CU+ serum in the same skincare routine as LUMENCE FORTE serum for hyperpigmentation. We recommend using Renova CU+ copper peptide firming serum by day and LUMENCE FORTE hyperpigmentation serum by night.
• Do not use in the same routine with vitamin C in pure form L-Ascorbic acid) and Ascorbyl Glucoside. Copper peptides lose their effectiveness in acidic PH. 
• Do not use in one routine with chelators, e.g. Disodium EDTA and retinoids.
