Medik8 and Allies of Skin are British skincare options offering serums, moisturizers, eye products, and toners built around hyaluronic acid and niacinamide. Medik8 is known for hyaluronic acid, which lengthens toxin wrinkle effect duration, while Allies of Skin is loved for niacinamide, which improves skin aging signs and decreases hyperpigmentation. Both brands suit dry skin best, though the first also fits dry sensitive skin and the second also fits oily acne-prone skin. The brands differ through their specific formulations, such as the first featuring Surface Radiance Cleanse, Oxy-R Peptides, and Total Moisture Daily Facial Cream, and the second featuring Molecular Saviour Probiotics Treatment Mist, Peptides & Antioxidants Firming Daily Treatment, and Peptides & Omegas Firming Eye Cream.
