Hyaluronic Acid Hydrating Calming Inner Dryness Serum 30ml

A serum that targets inner dryness with 82.3% hinoki cypress water

This hydration serum is formulated with 82.3% hinoki cypress water in place of purified water, so even the very first ingredient your skin meets is different by design. Eight types of hyaluronic acid—each with a different molecular size—penetrate every layer of skin to deliver deep moisture, while hinoki cypress water forms a protective moisture veil on the surface to lock in hydration. A dual-functional cosmetic for wrinkle improvement and brightening, it features niacinamide and adenosine to help even skin tone and support elasticity.

Dual hydration effect verified through clinical testing

Human application testing was completed at the OATC Skin Clinical Test Center.

• 109% increase in surface skin moisture (after single use)
• 8.24% increase in inner skin moisture (after single use, measured at 2.5mm depth)

Even a single application showed measurable hydration improvement both on the surface and within the skin.

For skin struggling with inner dryness and oil-moisture imbalance

The oil-free water gel texture absorbs quickly with no sticky residue. It's especially well-suited for dehydrated skin that feels tight inside yet looks shiny on the surface, and for combination skin that finds rich moisturizers too heavy. Apply before makeup to create a hydrated, seamless base, or use it as a lightweight finishing step in place of lotion during warmer months. On particularly dry days, layer it two to three times to build up deeper moisture.

Use after toner, before moisturizer

Soul Hydro Serum is designed to be applied right after toner, before your cream or lotion. After cleansing, apply toner first to prep and hydrate the skin, then follow with this serum to lock in moisture—this helps the next steps absorb more effectively.

Suitable for morning and evening use

In the morning, use it as a hydrating base before makeup. In the evening, use it to replenish moisture after a long day. When applied in the morning, it absorbs quickly without any sticky residue, so your base makeup won't slip or pill.

Dispense 1–2 pumps and gently smooth over skin

Dispense 1–2 pumps into your palm and gently smooth over the entire face. On particularly dry days, layer 2–3 applications for deeper hydration. If applying before makeup, allow about 30 seconds for full absorption to ensure a smooth, clean finish.

Recommended combinations by skin concern

• Dehydrated skin: After toner, layer Soul Serum 2–3 times, then seal with a lightweight hydrating cream
• Combination to oily skin: In summer, this serum alone can replace your lotion as a final step
• Imbalanced skin: Layer with a barrier-care serum or brightening serum for enhanced results

Storage and usage tips

For a cooling, soothing effect, store the serum briefly in the refrigerator before use. Keep it in a cool place away from direct sunlight. If redness, itching, or irritation occurs during use, discontinue immediately and consult a dermatologist.
