This active Retinol concentrate corrects wrinkles, firms the face, and reveals the complexion's radiance.

30 ml of excellence. One bottle. Skin transformed.

The patented Cold Retinol® — a world first from our laboratories — finally combines the legendary power of Pure Retinol, the gold standard in anti-aging, with an exclusive cryogenic technology (Tripeptide-1 + Lactate), enriched with birch sap, a source of life from Nordic lands. The result: an unprecedented intensity of action that is perfectly tolerated, respecting the skin's physiology rather than overwhelming it.

The birch is the first tree to awaken in extreme climates. While everything else still sleeps in the frozen soil, it already pushes its sap upward, reborn through the ice. This vital force, this determination to be reborn, is now captured in every drop of this concentrate — Retinol rebuilds, birch sap awakens. Cold and life, one to repair, the other to nourish: while fighting against time, the skin recharges with raw energy drawn from nature.

Where classic retinols heat up, irritate, and require an interminable wait, Cold Retinol® cools, soothes, and acts. A sensory as well as scientific revolution: the skin is treated in the cold, like post-inflammatory care, while receiving the world's most studied anti-aging molecule, combined with the natural hydration and soothing gentleness of birch sap.

Results:

✦ Corrects deep, surface, and dehydration wrinkles — the three fronts attacked simultaneously. Established furrows are filled, fine lines are blurred, and plumped skin regains its density and firmness.

✦ Firms cutaneous tissues and restores facial tone — the face is retensioned: the oval is reshaped, contours are redefined, and features are visibly lifted. The skin regains its density, resistance, and elasticity; skin sagging is visibly corrected for firmness that is visible and palpable from the very first weeks. A true tightening effect, day after day, without ever pulling or drying.

✦ Reveals the natural radiance of the complexion — no more dull, tired skin: the texture is refined, the complexion is unified, and light seems to literally radiate from within. Birch sap infuses the skin with a translucent freshness, like the first light of day filtering through the forest.

All skin types. Including the most sensitive and reactive: cryotechnology and the natural gentleness of birch sap open the path to retinol for those who previously had no access to it.

🌿 Daily Skincare Protocol: SAEVE Chaga Serum + Cold Retinol®

Key Concept:Birch sap first prepares and strengthens the skin barrier, retinol then precisely targets aging, and the cream seals and repairs as the final step.

Step 1: Gentle Cleansing

Action:Cleanse your face with a gentle cleanser, then rinse with lukewarm water.

Step 2: Birch Sap Base (SAEVE Chaga Serum)

Action:Take about 5 drops of SAEVE Chaga Serum, apply evenly to the forehead, cheeks, and chin, then massage gently until fully absorbed.

Key Point:Organic birch sap, the heart of this Chaga serum, is the core element of this step. In vitro studies show that birch sap promotes the expression of filaggrin and involucrin in keratinocytes, two proteins essential for maintaining the skin barrier and hydration.

Step 3: Cryogenic Anti-Aging (Cold Retinol®)

Action:Take an amount equivalent to a soybean (about 1 to 2 drops) of Cold Retinol®, apply in targeted dots on the forehead, cheeks, and wrinkled areas, avoiding the eye and lip contours. Gently smooth from the inside out.

Key Point:Upon application, experience its exclusive cryogenic technology that helps to instantly soothe the skin. Retinol stimulates collagen and extracellular matrix remodeling, while birch sap provides a complementary "stimulation + nutrition" action. It is recommended to wait about 1 to 2 minutes for the Chaga Serum to be well absorbed before layering.

Step 4: Sealing with Cream (Hydration and Repair)

Action:Once the Cold Retinol® is completely absorbed, apply a layer of moisturizing and repairing cream.

Cold Retinol®

Retinol, one of the forms of Vitamin A, is the gold-standard cosmeceutical active ingredient in the fight against signs of aging. When applied topically, this molecule stimulates cell regeneration as well as collagen production.

The Cold Retinol® complex was developed by our laboratory, which combined Pure Retinol with an exclusive cryogenic technology (Tripeptide-1 + Lactate) to replicate the anti-aging effect of intense cold. This patented technology further stimulates Type I collagen production (+35%) and boosts fibronectin synthesis (+33%), a youth protein responsible for dermo-epidermal cohesion, for enhanced efficacy against wrinkles and loss of firmness.

In tests, Cold Retinol® also demonstrated better cell viability compared to Retinol, which—when highly concentrated—is likely to cause sensations of discomfort at the beginning of treatment.

*Ex vivo immunolabeling instrumental test on human skin explants after 11 days; evaluation vs T0 demonstrating better efficacy vs retinol alone.
