Utilizes a stable and less irritating Vitamin C derivative (Sodium Ascorbyl Phosphate) at a more approachable concentration, making it ideal for beginners or those with sensitive skin. Positions the product as an accessible daily staple for preventative care rather than a high-potency corrective treatment, targeting a younger demographic. The use of a pump instead of a dropper offers a more hygienic and convenient application while also being a cost-effective choice. Achieves a significantly lower price point through the use of more economical packaging materials and a less complex formulation.
