Most dermatologists recommend 10 to 20% L-ascorbic acid as the ceiling for daily use. Isntree's Hyper Vitamin C 30 Cream pushes to 30%, which means this is not a beginner product. For users who've built tolerance to 20% vitamin C and want the stronger end of the category, this delivers. For sensitive skin or vitamin C beginners, this is too strong.\u003c\/p\u003e\n\n\u003cp\u003eThe cream format is notable. Most high-concentration vitamin C products are serums or ampoules. A cream delivers vitamin C over longer contact time with occlusive support. 20ml is a small size, appropriate for the concentrated active and signaling \"treatment intensity\" rather than daily all-over cream.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\n\u003cp\u003e30% L-ascorbic acid (or stable derivative) interrupts melanin production and reduces pigmentation over time. High-concentration antioxidant protection against free radicals. Ferulic acid and vitamin E stabilize the formula. Over 8 to 12 weeks of daily use, expect dramatic brightening and tone correction.
