Isntree Hyper Vitamin C 30 Cream: 30% Vitamin C at Cream Intensity
30% vitamin C is an aggressive concentration. 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.
The 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.
What It Does
30% 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. Not a subtle product.
Who It's For
- Vitamin C-tolerant skin: Built up from lower concentrations.
- Melasma or hyperpigmentation: Aggressive treatment for serious marks.
- Post-acne scarring: Fades marks over weeks.
- Dull, sun-damaged skin: Dramatic brightening.
- Experienced vitamin C users: Ready for strongest tier.

FAQ
Is 30% too much?
For sensitive skin, yes. For experienced vitamin C users, it's the next tier up. Start at 10 to 15% and build to 30% over months.
Will it sting?
Likely. 30% vitamin C causes tingling for most users. Burning or severe irritation means discontinue.
Can I use with retinol?
Space them. Vitamin C AM, retinol PM. Stacking same-time risks severe irritation.
How long until I see results?
Brightening in 4 to 6 weeks. Pigmentation reduction over 8 to 12 weeks.
How long does 20ml last?
2 to 3 months with conservative use.
