Thin consistency makes hand application difficult, requiring alternative methods users find inconvenient.
Runny vitamin C serum frustrates users with difficult hand application requiring unnecessary alternative methods.
This review is from Amazon.com for product:
SeoulCeuticals Korean Skin Care 20% Vitamin C Hyaluronic Acid Serum + CE Ferulic Acid - Potent Anti Aging, Anti Wrinkle Korean Beauty 1oz
This product is more like water, should be thicker. Hard to apply with just your hands, and yes there are other ways to apply. Should not have to tey another way.
Vitamin Basics & Tips
Vitamin C serums require careful formulation to balance potency and texture. The ideal viscosity should allow easy spreading without dripping, as proper application affects absorption. Many users don't realize that vitamin C (L-ascorbic acid) degrades quickly when exposed to light/air - watery formulas might indicate oxidation or low stabilizer content. For optimal results, serums should contain 10-20% vitamin C concentrations paired with ferulic acid and vitamin E to enhance stability and efficacy.
Application methods significantly impact skincare results. While some prefer fingertips, watery formulas often require cotton pads or patting techniques to prevent product waste. This conflicts with user expectations of premium skincare convenience. Environmental factors like humidity can further exacerbate texture issues, making formulation challenges crucial for tropical climates or travel-sized products.
Consumers should check for packaging that minimizes air exposure (airless pumps/dark glass) and combine vitamin C with complementary antioxidants. Those experiencing texture dissatisfaction might consider vitamin C derivatives like sodium ascorbyl phosphate, which offer similar benefits in more stable, potentially thicker formulations suitable for manual application.
