Dongkook Hyaluronic Acid

Hyaluronic acid appears in the Centelian 24 Boosting Ampoule (HA variant), the Madeca Hydra Solution Gel Cream, the Madeca Toning Essence, Derma Mask Pack series, the Moisture Lip Essence, and the Madeca Wrinkle Treatment Lip Balm. The Boosting Ampoule has the highest HA concentration; the Toning Essence has a supporting dose.

The set contains three 30 ml ampoules: a Glutathione ampoule targeting brightening, a Hyaluronic Acid ampoule for deep hydration, and a Pidialen Firming ampoule for elasticity. Each can be selected individually or purchased as the 3-type kit.

Use both in sequence: the ampoule delivers concentrated HA in the serum step; the Hydra Gel Cream seals hydration in the moisturiser step. If you can only choose one, the ampoule provides more targeted hydration, while the gel cream provides a broader moisturising film that works for most skin types without an ampoule layer.

The Hydra Gel Cream has a lighter gel-cream texture that absorbs faster and is better suited for oily skin or morning use. The standard Madeca Cream is denser, making it more effective for dry skin or nighttime barrier repair. Both contain Centella and hyaluronic acid but in different base formulations.

Apply thinnest to thickest: Toning Essence first, then HA Boosting Ampoule, then Hydra Gel Cream or Madeca Cream. If using a sheet mask, insert it after the ampoule and before cream. In the morning add SPF last.

Yes. HA and Centella asiatica are highly compatible. HA binds water to the skin surface; Centella reduces inflammation and supports barrier function. Together they address different hydration failure mechanisms without conflict or irritation.

Use the Toning Essence as your first hydration step and the Hydra Gel Cream as your moisturiser. Both absorb quickly without leaving a greasy residue. The HA Boosting Ampoule can be added between those steps on particularly dehydrated days. Avoid the Madeca Cream (the standard thick version) as it can feel heavy on oily skin in the morning.

Once or twice per week is standard. Apply after cleansing and toning, leave on for 15 to 20 minutes, remove and pat in remaining essence. Follow with ampoule and cream as normal. Daily use is not recommended as it can over-hydrate and disrupt the skin barrier.

The Lip Essence is a liquid that absorbs into the lip surface; the Lip Balm (available in Pink, Coral, and Plain) is a waxy product that seals on top. For very dry lips, layer the essence first then apply the balm over it. For mild dryness or colour preference, the balm alone is sufficient.

Initial plumping and softness from HA are visible within the first few days of consistent use. Deeper hydration improvement in the skin - reduced tightness, better texture - typically shows within 2 to 4 weeks when layering the Toning Essence with the ampoule and a cream. Longer-term results like reduced fine lines from dehydration take 6 to 8 weeks of daily use.

Yes. HA is compatible with both retinol and AHAs. Apply retinol or AHA products first (after cleansing) and follow with HA-containing layers. HA helps buffer any dryness or irritation caused by those actives. The Centella in Dongkook products adds additional calming support in this context.

Yes. The 3-type set pairs well with that goal: use the Glutathione ampoule (brightening) on alternate days with the Hyaluronic Acid ampoule (hydration), and use the Pidialen Firming ampoule when your focus is elasticity. This rotation keeps actives varied across your routine without overloading any single concern.
