Key Ingredients and Their Effectiveness
The brilliance of Medik8 C-Tetra Luxe lies in its harmonious blend of natural, nourishing ingredients crafted to enhance your skin’s beauty. At its core is 14% tetrahexyldecyl ascorbate, a gentle, stable vitamin C that penetrates deeply to brighten and unify skin tone without discomfort. Squalane, a lightweight moisturiser, nourishes the skin barrier, delivering long-lasting softness and hydration, while vitamin F (linoleic acid) maintains moisture balance for a supple feel.
Sustainably sourced Amazonian maracuja oil, rich in vitamin E and linoleic acid, softens and firms the skin, imparting a radiant, healthy glow. Optimised red ginseng enhances vitamin C’s brightening power by promoting an even tone, contributing to a luminous complexion. Vitamin E, a robust antioxidant, neutralises environmental aggressors, supporting a vibrant, healthy appearance. Natural oils like jojoba, olive, and sweet almond further enrich the formula, providing a velvety texture that elevates the experience. This blend, praised in beauty reviews on platforms like Cult Beauty, delivers luxurious results without heaviness, aligning with Medik8’s CSA philosophy (vitamin C and sunscreen by day, vitamin A by night).
The serum’s silky oil texture absorbs rapidly, leaving a non-greasy finish that’s perfect for morning routines. At Phibeauty, clients love how it extends the glow of professional treatments, enhancing their salon experience at home. Its fragrance-free nature, with a natural grapefruit scent, ensures suitability for sensitive skin, while its vegan certification and recyclable packaging reflect our commitment to sustainability. With 100% of users reporting softer skin after one week, this serum is a staple in our salon’s offerings.

What Is Brand Medik8?
Medik8 isn’t just another skincare name it’s a Skintellectual movement born in London. Founded by scientist Elliot Isaacs, we’re driven by a passion for blending chemistry with dermatology to create products that actually work.

The brand expanded rapidly, launching the CSA philosophy in 2015 to simplify effective routines. By 2020, Medik8 earned B Corp status, cementing its commitment to sustainability.
