Isntree Hyper Vitamin C 23 Serum 20ml brightens dull skin and targets uneven tone. Formulated with 23% pure Vitamin C (Ascorbic Acid), this concentrated serum helps reduce the appearance of dark spots and hyperpigmentation for a more radiant complexion.
Vitamin E complements Vitamin C’s antioxidant benefits, while Panthenol helps moisturise, soothe and support the skin barrier. Birch Juice provides additional hydration. The lightweight formula absorbs quickly without leaving a heavy finish.
How to use
After toner, apply 2–3 drops to your face and gently pat until absorbed. Follow with moisturiser. Due to its high Vitamin C concentration, use once every 3–4 days, particularly when introducing it to your routine. Use sunscreen during the day.
Store in a cool, dark place away from direct sunlight.
Frequently asked questions
What does Vitamin C serum do?
Vitamin C helps brighten dull skin, improve the appearance of uneven tone and reduce the visibility of dark spots. It also provides antioxidant care.
How often should I use this serum?
The recommended frequency for this concentrated formula is once every 3–4 days. More frequent application is not necessarily better. Reduce use or stop if your skin becomes irritated.
Is Vitamin C serum safe to use?
Many people tolerate Vitamin C well, but this is a strong 23% formula and may cause irritation. Patch test before applying it to your whole face. Avoid broken or irritated skin and the eye area. Stop using it if you develop persistent stinging, redness or discomfort.
Is it suitable for sensitive skin or beginners?
This high-strength formula may not be the best starting point for sensitive skin or first-time Vitamin C users. A lower-strength serum may be easier to tolerate.
Should I use it in the morning or evening?
It can be used in either routine, depending on your preference and skin tolerance. Use sunscreen during the day, whichever time you apply the serum.
Do I still need sunscreen?
Yes. Vitamin C does not replace sunscreen. Daily sun protection is especially important when caring for dark spots and uneven skin tone.
Can I use it with other strong skincare products?
Introduce this serum on its own before combining it with other active treatments. Using exfoliating acids or retinol in the same routine may increase irritation, so consider using them on different days.
How long does it take to see results?
Results vary. Improvements in dark spots and uneven tone take consistent use over time, rather than appearing overnight. Follow the recommended frequency instead of applying more to speed up results.
