TOSOWOONG Turmeric Kojic Acid Brightening Serum 33ml — Triple‑Layer Shake‑to‑Activate, Fast‑Absorbing

TOSOWOONG Real Turmeric Kojic Acid Serum is a shake-to-activate, triple-layer Korean brightening serum formulated to target dark spots, uneven tone and dull texture.

Designed as a concentrated treatment, this 33ml (1.11 fl. oz.) serum blends high-potency actives—7,000ppm kojic acid and 1,500ppm turmeric—alongside alpha arbutin, glycolic acid, niacinamide and astaxanthin. The three-phase bottle separates oils, water-soluble brighteners and actives until shaken, delivering a freshly mixed formula that supports skin clarity and surface renewal without heavy residue. The lightweight texture absorbs quickly and layers easily under moisturizers and sunscreen in daytime routines or before richer creams at night.

How does the shake-to-activate triple-layer system work?

Each bottle contains three distinct layers that keep sensitive ingredients stable until use. Shaking the serum fuses the oil and water phases so the actives are freshly combined, which increases their potency and reduces degradation from air exposure.

• Preserves ingredient stability by separating phases until activation
• Delivers a uniform, fast-absorbing texture after shaking
• Helps maintain efficacy of kojic acid and turmeric over time

What visible concerns can this serum address?

The multi-ingredient formula targets irregular pigmentation, sun spots, and a lackluster complexion by combining tyrosinase-modulating and exfoliating ingredients. Over consistent use it aims to even skin tone, refine texture and boost overall radiance without leaving heavy oils.

• Kojic acid and alpha arbutin help reduce the appearance of dark spots
• Glycolic acid supports gentle exfoliation and smoother skin surface
• Turmeric and astaxanthin add antioxidant support to calm and refresh skin

Is this serum suitable for sensitive or combination skin?

The formula has completed irritation testing and was developed to be gentle, but it still contains active acids and high-strength brighteners. Patch-testing is recommended; start with every-other-day use and layer under a moisturizer to minimize potential dryness or sensitivity while skin adjusts.

• Dermatologist-tested for irritation; suitable for many skin types
• Begin with low frequency and increase as tolerated
• Always follow with SPF during daytime use to protect newly revealed skin

How should I include this serum in my skincare routine?

Use the serum after cleansing and toning but before creams and oils. For daytime, apply thinly and finish with broad-spectrum sunscreen; at night, pair with a calming moisturizer. Consistency is key—visible improvements typically appear with ongoing nightly or alternate-night application over weeks.

• Shake well, dispense 1–2 pumps, and smooth evenly over targeted areas
• Use once daily to start, increasing to nightly if tolerated
• Combine with SPF in daytime routines to maintain results
