A vitamin C serum may create a tingling or stinging sensation when the formula is acidic, the active level is high, the skin barrier is compromised or the product is combined with other intensive steps. For brands, this is a formula, positioning and instruction issue.
Suzhou Suvael helps beauty companies develop vitamin C concepts with appropriate derivative selection, packaging and responsible claims.
Choose the Vitamin C System
L-ascorbic acid and vitamin C derivatives have different pH, stability and sensory requirements. The choice should reflect target potency, customer experience, packaging and market positioning.
Balance Efficacy Positioning and Comfort
Higher percentages are not automatically better. Humectants, soothing agents and the rest of the routine influence how the finished product feels.
Packaging and Directions
Light- and oxygen-sensitive systems may need opaque, air-limiting packaging. Directions should explain gradual use, patch testing and when to stop if discomfort persists.
