• Smoothes the skin.

Medex Serum Lumière is a high-performance facial serum that targets the root cause of dull, uneven skin by stimulating the production of Filaggrin — the essential epidermal protein responsible for a strong, healthy skin barrier. At the heart of this serum is a potent extract from Fagus Sylvatica (beech buds), rich in flavonoids, phytohormones, and peptides that energise keratinocytes and promote Filaggrin synthesis. Working in synergy with Sodium Hyaluronate, these actives regulate moisture levels in the upper skin layers, reinforcing the barrier so that light penetrates evenly and reaches deeper skin tissue. The result is visibly healthier, more luminous skin with a balanced, even complexion. Thanks to its plant-based Glycerin, this serum also supports the skin's Natural Moisturizing Factor, keeping skin supple and resilient throughout the day. Medex Serum Lumière is particularly suited to skin prone to impurities, hyperpigmentation, or post-acne scarring, and delivers optimal results when used alongside the Medex Light Mask. Free from silicones, paraffin oil, and microplastics — housed in eco-conscious glass packaging.

Serum Lumière works at a cellular level: the Fagus Sylvatica extract (young beech buds) boosts the energy levels of keratinocytes, stimulates oxygen uptake and activates the production of Filaggrin. This skin protein binds keratin fibres in the epidermis and supports the Natural Moisturizing Factor, resulting in a firm, well-structured skin barrier. Hyaluronic Acid (Sodium Hyaluronate) and plant-derived Glycerin work in synergy to lock moisture deep into the skin and preserve tissue elasticity. The combined effect delivers a balanced moisture level, an intact barrier and uniform light transmission — for visibly radiant skin with an even complexion.

Apply Medex Serum Lumière morning and/or evening to cleansed skin. Dispense 2–3 drops onto your fingertips and gently press the serum into your face and neck, avoiding the eye area. Allow to absorb fully before applying your moisturiser or SPF. For best results, use consistently as part of your daily skincare routine in combination with the Medex Light Mask.

• Hyaluronic acid – Can hold up to 1000 times its weight in moisture and provides intensive hydration
• Glycerin – Intensely hydrates and has a soothing effect.

Fagus Sylvatica Extract – Extract from young beech buds, rich in flavonoids, phytohormones, and peptides that increase the energy levels of keratinocytes. This stimulates oxygen uptake and promotes the production of filaggrin, a skin protein essential for the skin barrier and moisture balance.

Filaggrin – An important skin protein that binds keratin fibers in the epidermis and contributes to moisture balance by supporting the Natural Moisturizing Factor.

Glycerin (natural source) – Plant-based glycerin binds and retains water, essential for the skin's moisture balance. It plays an important role in the Natural Moisturizing Factor.

Hyaluronic Acid (Sodium Hyaluronate) – A complex molecule naturally found in the connective tissue of the skin. Hyaluronic acid provides intense hydration and helps maintain the elasticity and viscosity of tissues, which is crucial for healthy, hydrated skin.
