Anua Acid

PDRN stands for polydeoxyribonucleotide, a compound derived from salmon DNA that is used in dermatology for skin repair and regeneration. In cosmetic use, it supports cell turnover, helps rebuild the moisture barrier, and is often combined with HA because they target different layers of skin hydration. Anua uses PDRN as the defining ingredient of its Hyaluronic Acid 100 series, where it appears alongside HA to provide both surface moisture and deeper barrier support. Products like the PDRN Hyaluronic Acid Capsule 100 Serum and PDRN 100 Hyaluronic Acid Booster Toner carry this pairing throughout the lineup.

The PDRN Hyaluronic Acid Capsule 100 Serum uses a micro-encapsulation structure where HA is contained inside tiny capsules suspended in the serum base. When applied, the capsules burst and release HA at the skin surface, which Anua claims allows more controlled delivery compared to a standard HA serum. The texture is lightweight and slightly gel-like. The capsule format is available in both the standard 30ml travel size and a larger full-size version, making it practical to test before committing to a full bottle.

The PDRN 100 Hyaluronic Acid Booster Toner and the PDRN Hyaluronic Acid Moisture Capsule Mist serve different moments in a routine. The booster toner is designed as a first-step hydration layer, applied after cleansing to prepare skin to absorb subsequent products. It has a slightly thicker consistency than a traditional watery toner. The capsule mist, available in 30ml and 100ml, is intended for use mid-routine or on top of makeup as a hydration refresh. Its mist format carries the same PDRN-HA combination in a lightweight spray, which is useful for travel or desk use during the day.

This collection includes two pad formats with different target skin concerns. The PDRN 100 Hyaluronic Acid Glow Pad focuses on brightening and smoothing, using PDRN and HA together with exfoliating properties to improve skin texture and radiance over time. The 8 Hyaluronic Acid Catechin Calming Pads take a different approach: catechin, a polyphenol from green tea, is added alongside HA to reduce redness and calm reactive or sensitized skin. The Catechin Calming Pads are the better fit for skin that tends to flush or react to environmental stressors, while the Glow Pad suits skin that wants smoother texture alongside moisture.

The 8 Hyaluronic Acid Hydrating Gentle Foaming Cleanser is the only cleansing step in this collection, and it uses a low-foam formula with eight types of hyaluronic acid. Most foaming cleansers strip moisture from the skin surface during the cleansing step, but the HA loading in this formula is intended to maintain skin hydration throughout the wash and rinse. It is suited for morning cleansing or for anyone whose skin feels tight or dry after washing. Adding it as the first step creates a consistent HA foundation before the rest of the PDRN HA routine is layered on.

The products in this collection map cleanly to a step-by-step hydration routine. Start with the 8 HA foaming cleanser, then apply the PDRN Booster Toner as the first hydration layer. The PDRN Capsule 100 Serum follows next while skin is still slightly damp to lock in the booster toner. Apply the PDRN 100 Moisture Cream last as the sealing step. The Glow Pad or Catechin Calming Pads can replace the toner step on evenings when you want light exfoliation or active calming treatment. The Capsule Mist works over this finished routine or as a midday refresh. Using products from the same PDRN HA series reduces the risk of ingredient conflicts since the formulas are built to work together.

Several products in the PDRN HA 100 line come in 30ml versions: the Capsule 100 Serum 30ml, and the Moisture Capsule Mist 30ml are both sold individually. There is also a dedicated set pairing the PDRN Hyaluronic Acid Capsule 100 Serum 30ml with the PDRN Hyaluronic Acid 100 Moisture Cream 30ml. That set is useful for first-time buyers who want to try the core serum-plus-cream pairing before buying full-size bottles. Travel sizes also fit carry-on liquid limits, making the line accessible for travel without decanting.

Hyaluronic acid works across skin types because it pulls moisture from the environment into the skin without adding oil. The PDRN Hyaluronic Acid Cream has a moisturizing finish that suits dry to normal skin as a stand-alone moisturizer. Oily or combination skin types typically find the serum and toner formats more comfortable, since those finish lighter without the occlusive layer from the cream. The Catechin Calming Pads are well-suited to sensitive or reactive skin because catechin has documented anti-inflammatory properties. The foaming cleanser is mild enough for daily use on most skin types, though those with very dry or compromised barriers may prefer to use it only in the morning and use a non-foaming cleanse at night.
