Jumiso All Day Vitamin Pure C 5.5 Glow Serum 30ml

The Jumiso All Day Vitamin Pure C 5.5 Glow Serum is a refreshingly approachable take on vitamin C — strong enough to deliver real radiance, gentle enough that you can actually use it every day. Most pure ascorbic acid serums sit at a low pH that burns sensitive skin and forces a slow ramp-up phase. This one is buffered to pH 5.5, which keeps the formula stable and skin-friendly while still letting the 5% L-Ascorbic Acid do its brightening work. The result is a serum that fades post-acne marks, softens hyperpigmentation, and adds a healthy glow without the redness or tingling.

What makes this Jumiso glow serum stand out is its supporting cast. Niacinamide reinforces the brightening effect and helps regulate oil, while Centella Asiatica calms any potential irritation before it starts. The lightweight, water-thin texture absorbs in seconds and layers seamlessly under sunscreen — making it a great choice for beginners, sensitive skin types, and anyone tired of vitamin C serums that oxidize too quickly. Pair it with a hydrating layer like the COSRX Advanced Snail 96 Mucin Power Essence for an even smoother finish.

Key Ingredients

Here’s what powers the Jumiso All Day Vitamin Pure C 5.5 Glow Serum:

Ascorbic Acid (Pure Vitamin C — 5%) The gold-standard form of vitamin C that brightens skin, fades dark spots, and supports collagen. At 5% and pH 5.5, it delivers visible results without the irritation typical of higher-concentration formulas.

Niacinamide (Vitamin B3) Works alongside vitamin C to even out skin tone, minimize the look of pores, and strengthen the moisture barrier. It also helps regulate oil for a smoother, less shiny finish.

Centella Asiatica Extract (Cica) A well-researched soothing botanical that calms irritation and supports skin recovery. It’s the reason this serum feels comfortable even on sensitive complexions.

Sodium Hyaluronate A lightweight hyaluronic acid derivative that pulls moisture into the skin’s surface, leaving it plump, soft, and hydrated.

Adenosine A skin-conditioning ingredient that supports a smoother, firmer-looking complexion with continued use.

Allantoin Gentle and soothing, allantoin softens skin texture and helps reduce any sensitivity from active ingredients.

Panthenol (Vitamin B5) Adds hydration and helps reinforce the skin barrier, keeping the complexion comfortable and resilient.

How to Use

1. Cleanse and Tone — Begin with clean skin and your usual hydrating toner.
2. Dispense 3-4 Drops — Take a few drops onto your palm or fingertips.
3. Press Into Skin — Gently pat across the face, focusing on areas with dark spots or dullness.
4. Follow With Moisturizer — Lock everything in with your favorite cream, and always use SPF in the morning.

Use: Both AM and PM Where in routine: After toner, before moisturizer Pro Tip: Store the bottle in a cool, dark place to keep the vitamin C fresh and potent. If the serum turns deep yellow or orange, that’s a sign of oxidation — and time to replace it.
