JUMISO 20% Niacinamide Dark Spot Serum 2-Pack, Tranexamic Acid & Glutathione – 2 x 40ml, Soothing Korean Brightening

JUMISO's 20% Niacinamide Dark Spot Serum 2-pack is a high-strength Korean brightening serum designed to help reduce the appearance of dark spots and uneven tone while keeping skin calm.

If you want an intensive, multi-ingredient approach to fading post-acne marks and stubborn pigmentation while maintaining a soothing finish, this value set gives two full 40 ml bottles so you can stay consistent. The formula pairs one of the highest available niacinamide concentrations with tranexamic acid, glutathione and hexylresorcinol, and a Centella-based buffering complex to lessen irritation. It’s fragrance-free, vegan, dermatologist-tested and made in Korea.

How does this serum target dark spots and uneven skin tone?

The serum uses several actives that work through different mechanisms to address pigmentation. Niacinamide at 20% supports visible brightening, while tranexamic acid and glutathione complement it to reduce the look of discoloration over time.

• 20% niacinamide for multi-pathway brightening
• Tranexamic Acid (TXA) to help reduce the appearance of stubborn marks
• Glutathione and hexylresorcinol for antioxidant and brightening support
• Formulated to layer well under SPF and makeup

Will a 20% concentration be irritating to my skin?

High-percentage niacinamide can feel intense for some skin types; JUMISO buffers this with a Triple Centella Complex plus allantoin and multi-weight hyaluronic acid to soothe and maintain comfort. The product is designed for gradual introduction so reactive skin can adapt without harsh disruption.

• Centella asiatica derivatives calm visible redness
• Allantoin and hyaluronic acids support hydration and barrier comfort
• Suggested start: 2–3 nights per week, then increase as tolerated
• Avoid layering with retinol, high-strength vitamin C or AHA/BHA simultaneously

How quickly can I expect to see changes, and how should I use it?

Results depend on individual skin and consistency. In a clinical study, users saw measurable improvements in clarity and redness within two weeks; real-world timing varies, so plan for several weeks of steady use. Apply sparingly after cleansing and before moisturizer, and always use sunscreen each morning.

• Use 2–3 drops per application after cleansing
• Apply at night initially 2–3 times weekly, build up to nightly if tolerated
• Morning sunscreen is essential when using brightening actives
• Do not combine in the same routine with retinoids or strong acids

Why buy the 2-pack instead of a single bottle?

The two-bottle set is a practical choice for uninterrupted treatment: one bottle can stay at home while the other travels, or you can share with a family member to extend usage. Consistency matters for pigment improvement, and the 2-pack covers about 3–4 months with normal use.

• Two 40 ml (1.35 fl oz) bottles for longer continuous treatment
• Convenient for travel or sharing, avoids running out mid-course
• Better value per month versus single small tubes

Who this is for: shoppers wanting a targeted, high-strength topical option for the visible appearance of dark spots, post-blemish marks and uneven tone who are comfortable introducing a potent active gradually. It’s aimed at adults seeking a fragrance-free, vegan Korean formulation that layers cleanly under makeup and sunscreen. If you have highly reactive or barrier-compromised skin, start slowly and consider consulting a skincare professional about integrating strong actives into your routine.
