The #1 face serum in the United Kingdom, featuring retinal. Retinal (or retinaldehyde) is a potent form of vitamin A present in Medik8's iconic serum, Crystal Retinal, available in different percentages, ranging from 0.01% in potency 1 to 0.24% in potency 24. Compared to retinol, it is just one step away from being converted into the active form of vitamin A (retinoic acid), which all forms of vitamin A need to become more effective on the skin. As a result, retinal acts 11 times faster on the skin than retinol and, in this case, without increasing the potential for irritation due to its unique formula. The factors that determine the effectiveness of vitamin A are concentration, stability, encapsulation method, and formulation. The brand's innovative stability system includes a recognized encapsulation technology, a patented carrot seed oil complex, and airless packaging (which prevents air from entering).
With just one bottle of Crystal Retinal, the brand clinically demonstrated younger-looking, brighter, smoother skin with fewer wrinkles, lines, spots, and improved firmness. Additionally, Medik8's patented stabilization system for retinal ensures potency and effectiveness without causing irritation, making the choice of retinal percentage important (among the six available in the brand). This serum also contains hyaluronic acid and glycerin for visible hydration and antioxidant vitamin E. It resembles more a lotion, being extremely comfortable and hydrating.
Personalization in cosmetics is a rapidly growing and much-needed trend, driven by the demand for solutions tailored to the specific needs of each skin/person. Instead of generic products, brands are increasingly investing in formulas that consider not only the skin type but also individual concerns (acne, spots, aging signs, etc.) and lifestyle. This approach creates more effective products that directly address each person's expectations. Personalization is transforming how we care for our skin, leading to better results and a unique experience. Retinal is a potent ingredient in cosmetics, making it essential to adapt the percentage to each individual.
