Dive In Low Molecular Hyaluronic Acid Serum 50ml

A five-weight hyaluronic acid serum that floods skin with deep, lasting hydration

This moisture serum is formulated with five types of hyaluronic acid, each with a different molecular weight—from high to low. High molecular weight HA forms a protective moisture veil on the skin's surface, medium weight HA boosts hydration retention, and low molecular weight HA penetrates deeply to replenish moisture from within. The texture absorbs quickly without the typical stickiness of hyaluronic acid, so you can layer multiple serums without any heavy feel.

Clinically proven 48-hour moisture retention after just one use

A single application was shown to maintain hydration for up to 48 hours in a human application test. Clinical studies also confirmed that consistent use over four weeks improved moisture content in the deeper layers of the stratum corneum, delivering true deep hydration. It has completed a sensitive skin irritation test, making it safe for even reactive skin types.

Soothing hydration ingredients in a skin-friendly, mildly acidic formula

Beyond the five hyaluronic acids, this serum contains panthenol to reinforce the moisture barrier and support skin calming, plus allantoin to comfort irritated skin. The mildly acidic pH mirrors that of healthy skin, helping maintain balance without disruption. It's also vegan-certified and formulated with a clean ingredient philosophy, so it's ideal for those mindful about what they put on their skin. This serum is especially well-suited for anyone who experiences tightness after cleansing or wants serious hydration without any sticky residue.

Use after toner, during the essence or serum step

This is a hydrating serum designed to be used after cleansing and toning, when your skin is prepped and ready for moisture. It features five different molecular weights of hyaluronic acid to deliver hydration from the surface all the way into deeper layers. Follow with a cream or lotion to lock in all that moisture and prevent it from evaporating.

Suitable for morning and evening use

Thanks to its mildly acidic formula, it's gentle enough to use twice daily without overwhelming your skin. In the morning, layer it under makeup as a hydrating base. At night, use it to replenish moisture lost throughout the day. It's especially helpful during seasonal transitions or in air-conditioned or heated environments, where it can help relieve that tight, parched feeling.

Dispense a moderate amount and pat gently to absorb

Pump 1–2 times into your palm, spread evenly across your face, then pat gently with your fingertips to help it sink in. The texture is refreshingly lightweight with none of the sticky residue hyaluronic acid can sometimes leave behind, so it layers beautifully without feeling heavy. For extra-dry areas, feel free to apply a second layer for targeted care.

Recommended pairings by skin type

• Dry skin: Follow with a rich, deeply hydrating cream applied generously to seal in moisture
• Combination skin: Apply lightly on the T-zone, then add an extra layer on the cheeks and jawline for balanced hydration
• Sensitive skin: Formulated with panthenol and allantoin, it delivers soothing hydration without irritation
