Isntree Hyper Vitamin C 23 Serum 20ml

Isntree Hyper Vitamin C 23 Serum 20ml is a high-potency Korean vitamin C serum designed to brighten the appearance of uneven skin tone and dullness, concerns that become more noticeable under Bangladesh’s year-round UV exposure and urban pollution. This lightweight serum delivers one of the highest concentrations of vitamin C available in a stable, fast-absorbing formula—ideal for anyone whose skin looks tired, patchy, or less radiant than it used to, especially after long hours in air-conditioned offices or under the midday sun.

What is the Isntree Hyper Vitamin C 23 Serum 20ml and how does it work?

Isntree Hyper Vitamin C 23 Serum 20ml is a water-based serum that uses 23% vitamin C—specifically, a stable derivative called sodium ascorbyl phosphate—to help reduce the look of dark spots, post-acne marks, and dullness. Vitamin C works by interfering with the enzyme that produces melanin, the pigment responsible for uneven tone. Over time, this helps even out the appearance of skin colour and restores a brighter, more uniform look.

The formula also includes antioxidants that help neutralise free radicals generated by UV rays and pollution—two unavoidable stressors in Dhaka’s environment. Because vitamin C degrades when exposed to light and air, the serum comes in an opaque, airless pump bottle that keeps the active ingredient fresh and effective throughout its use.

Best for these skin types and concerns

• Dull, tired-looking skin that lacks radiance
• Uneven tone, including post-acne marks and sun-induced dark spots
• Skin that shows early signs of photoaging from frequent sun exposure
• Combination or oily skin that needs brightening without heaviness
• Anyone who wants to maintain an even, glowing complexion year-round

Those with very sensitive skin or a history of irritation from vitamin C should patch test first. If redness or stinging occurs, discontinue use or try applying it over a moisturiser to buffer the strength.

How to use the Isntree Hyper Vitamin C 23 Serum 20ml

1. After cleansing and toning, dispense 2-3 drops of the Isntree Hyper Vitamin C 23 Serum 20ml onto your fingertips.
2. Gently press the serum into your face and neck, avoiding the eye area. Do not rub—pressing helps absorption without dragging the skin.
3. Use in the morning, before moisturiser and sunscreen. Vitamin C works best when layered under SPF, as it boosts sun protection and helps prevent further UV-induced pigmentation.
4. If your skin feels dry after application, follow with a lightweight moisturiser to lock in hydration.
5. Always apply a broad-spectrum sunscreen (SPF 30 or higher) as the final step—this is non-negotiable in Bangladesh’s strong sunlight, where UV rays can reverse the brightening effects of vitamin C.

What to expect over time

Brightening with the Isntree Hyper Vitamin C 23 Serum 20ml is a gradual process. Most people notice a subtle glow within the first two weeks, while more noticeable evening of tone and fading of dark marks typically takes four to six weeks of consistent use—provided sunscreen is applied daily. Because vitamin C works on the surface and doesn’t alter skin structure, results depend on continued use; stopping the serum means the appearance of uneven tone may slowly return, especially under Bangladesh’s intense UV conditions. Think of it as a long-term partner in maintaining a clear, radiant complexion, not a quick fix.
