Wake Up to Brighter, More Radiant Skin – The KT939 Vegan Sleep Mask

K-beauty innovation meets clinical efficacy. Our KT939 Vegan Sleep Mask is a revolutionary overnight jelly cream designed to deliver visible whitening, brightening, and dark spot correction while you sleep. Developed for OEM and ODM Korean skincare brands, this vegan, organic, and cruelty-free formula is suitable for all skin types – including sensitive skin – and features the patented active ingredient KT939, a next-generation tyrosinase inhibitor that targets hyperpigmentation at its source.

The Science Behind KT939 – A Whitening Breakthrough

KT939 is a proprietary tyrosinase inhibitor that has received INCI naming approval .Clinical studies demonstrate that KT939 offers 4 times higher melanin inhibition compared to Thiamidol, 100 times higher than 577, and 300 times higher than 377. Unlike traditional brightening agents that can cause irritation, KT939 exhibits excellent safety profiles in acute toxicity, skin irritation, and sensitization tests – making it suitable even for sensitive and reactive skin types .

The ingredient works by blocking the tyrosinase enzyme – the key rate-limiting step in melanin synthesis – effectively reducing melanin production at the source. Additionally, KT939 demonstrates antioxidant properties by activating the ARE/NRF2 pathway and exhibits anti-inflammatory effects by downregulating pro-inflammatory cytokines.This multi-mechanism approach addresses pigmentation from multiple angles.

Why Choose a Sleeping Mask Format?

Nighttime is when skin undergoes its natural repair and regeneration cycle. A sleeping mask (or sleeping pack) creates an occlusive barrier that locks in active ingredients while you rest, allowing for deeper penetration and prolonged contact time compared to rinse-off masks. Our jelly texture absorbs quickly without greasiness – no pillow sticking, no sticky residue.

Key Ingredients & Their Synergistic Benefits

1. KT939 (Patented Brightening Complex)

• Inhibits tyrosinase activity with IC50 value of 70nM – one of the most potent reported .

• Reduces melanin production with IC50 of 0.36μM .

• Provides antioxidant protection via NRF2 activation

• Delivers anti-inflammatory benefits for calmer skin

2. Hyaluronic Acid + Glycerin
This powerful hydration duo creates a moisture reservoir that plumps the skin overnight. Hyaluronic acid holds up to 1000x its weight in water, while glycerin acts as a natural humectant that draws moisture into the stratum corneum – leaving you with dewy, glass-skin radiance by morning.

3. Vitamin C (Stabilized)
Works synergistically with KT939 to inhibit melanin production through a complementary pathway. Vitamin C also provides potent antioxidant protection against UV-induced free radicals and helps boost collagen synthesis for firmer, more resilient skin.

4. Herbal Blend + Plant Extracts
A proprietary herbal complex (including Centella Asiatica, chamomile, and green tea) provides additional soothing and anti-inflammatory benefits – essential for preventing post-inflammatory hyperpigmentation often triggered by breakouts or irritation.
