Primay True Hydrating Serum

Triple panthenol and 5 types of hyaluronic acid for surface-to-deep hydration

A clean hydration serum that fortifies the skin barrier from within. Triple panthenol forms a moisture-locking layer between the skin's surface cells, while 5 types of hyaluronic acid deliver targeted hydration to different skin layers—smoothing the surface and plumping from within. Bamboo extract sourced from the pristine Himalayan region provides natural silica to help support skin elasticity and soothe irritation.

Clinically proven instant hydration boost

In human application tests, just one use showed visible hydration improvement.

• Surface hydration improved by 212.23%
• Deep hydration improved by 12.29%
• Skin barrier recovery after physical stress improved by 75.80%

Scored 0.000 on the primary skin irritation test, confirming non-irritating status. Also awarded Excellent grade by Dermatest Germany and certified vegan by the Korea Agency of Vegan Certification and Services—safe even for sensitive skin.

For sensitive, dehydrated skin

Perfect for those looking to address dryness and sensitivity at the same time. Dispense an appropriate amount, smooth over the entire face, and gently pat to help absorption. For extra-dry areas, apply a second layer to lock in even more moisture. Experience all-day comfort and balanced hydration with a formula that absorbs deeply instead of sitting on the surface.

After toner, during the essence or serum step

Use after cleansing and toning, when your skin is prepped and ready for a deep surge of hydration. Follow with a cream to lock in moisture and prevent it from evaporating. Because of its lightweight texture, apply it like an essence—before heavier creams—for the most natural layering.

Suitable for morning and evening use

In the morning, use it as a hydrating base before makeup. In the evening, let it replenish moisture lost throughout the day. It's been tested as non-irritating, so it's gentle enough for daily use without overloading your skin.

Dispense a moderate amount and pat to absorb

Pump 2–3 times into your palm, spread evenly across your face, then gently pat with your palms to help it absorb. For extra-dry areas like the cheeks or jawline, layer on a second application for an even more hydrating finish.

Recommended combinations by skin concern

• Dry, tight skin: After a deeply hydrating toner, apply this serum generously and seal it in with a rich cream.
• Sensitive, reactive skin: Pair with a calming toner to maximize panthenol's barrier-strengthening benefits.
• Combination skin with inner dryness: Combine with a lightweight, oil-free moisturizer to keep your surface fresh while locking in hydration underneath.

Storage and usage notes

Store in a cool place away from direct sunlight. Though it's vegan-certified and earned a Dermatest Excellent rating for gentleness, discontinue use if redness or discomfort occurs and consult a dermatologist.
