ABSTRACT: In the era of beauty trends and increased skin-health awareness, consumers actively look for cosmetic products that align with their skin needs. The ongoing innovation in cosmetic formulations has given rise to advanced serums. Vitamin C serums have gained remarkable popularity, especially due to the decline of Vitamin C levels in the skin as part of the ageing process and their strong antioxidant properties (1). It is also important to mention, that maintaining its efficacy relies significantly on the other ingredients in cosmetic formulation and packaging.
INTRODUCTION
With the increased accessibility to information, consumers are now better informed about the effectiveness and the correct application of skincare products than ever before. Recognizing that a higher concentration of active ingredients provides enhanced skin benefits, the spotlight has shifted towards serums.
Cosmetic serums have become a staple in global beauty
routines, influenced by skincare trends and the desire for efficient, scientifically proven solutions. They are concentrated formulas designed to deliver potent ingredients, such as antioxidants, vitamins, and peptides to the skin. These formulations typically have a lightweight and fast-absorbing texture, allowing the key ingredients to penetrate the skin more effectively. Serums are often used as a part of morning and evening skincare routines, applied after cleansing and before moisturizing.
Another important feature is the ability to target specific skincare requirements. In other words, skin concerns often require particular ingredients to address them. For example, serums can be formulated with retinol for anti-ageing (2), hyaluronic acid for hydration properties (3), niacinamide for maintaining skin balance (4), or vitamin C for brightening effect (5). This enables individuals to purchase a serum that corresponds to their unique skin needs.
Vitamin C or biologically active form- L- ascorbic acid, has long been recognized for its antioxidant and brightening features, as well as its role in supporting collagen synthesis. However, because of the hydrophilic nature and instability, it has been challenging to incorporate it in cosmetic products (5). When it comes to the formulation, cosmetic scientists are bombarded with numerous questions. What form of Vitamin C is the most stable in cosmetic formulation? What about the optimal pH range and packaging? Are there any interactions between other ingredients in the serum?
