Anua PDRN Hyaluronic Acid 100 Moisturizing Cream - Lightweight, Non-Comedogenic Daily Moisturiser

"A Moisturizer That Stays Through the Day and Asks Nothing Complicated in Return"

Yuki, Seongsu-dong. My skin runs dry all year and sensitive enough that new products regularly cause redness that takes several days to settle. What I look for in a daily moisturiser is not dramatic. Something that holds moisture in without heaviness, sits cleanly under makeup on the days I wear it, and does not introduce a new variable I have to test.

The ANUA PDRN Hyaluronic Acid 100 Moisturizing Cream is fragrance-free, artificial colorant-free, and built around a hydration system deep enough to earn the "100" in the name - ten distinct forms of hyaluronic acid, working at different depths. That kind of layered construction makes sense to me. Not one ingredient doing one thing. Many forms, many depths, the same result.

What does PDRN actually contribute to a daily moisturiser?

PDRN here is Sodium DNA - salmon-derived polydeoxyribonucleotide - listed in the ingredient deck. In this formula, it functions as a skin-revitalising compound that works alongside the hyaluronic acid complex to support hydration and radiance from within rather than just at the surface. ANUA's clinical testing for this cream showed collagen improvement of up to 68.3% and a moisture plumping effect improvement of up to 10.79%. The 100-hour dermal hydration result is the most relevant number for daily use - it suggests the formula is building sustained moisture retention, not just immediate surface softness.

🌙 Yuki's Note: Sodium DNA - the INCI name for PDRN (polydeoxyribonucleotide) in cosmetic ingredient lists. Derived from salmon in this formula. Studied for its role in skin regeneration and moisture support.

Why does this formula contain ten forms of hyaluronic acid?

Each form of hyaluronic acid has a different molecular weight, which determines how deeply it penetrates. Hydrolyzed Hyaluronic Acid and Hydrolyzed Sodium Hyaluronate are smaller fragments that travel deeper. Sodium Hyaluronate Crosspolymer and Sodium Acetylated Hyaluronate form a film at the surface to seal moisture in. The forms in between - Sodium Hyaluronate, Potassium Hyaluronate, Dimethylsilanol Hyaluronate, Hydroxypropyltrimonium Hyaluronate, Hyaluronic Acid, and Sodium Hyaluronate Dimethylsilanol - address moisture at the layers in between. The result is hydration across the full depth of the skin rather than at one level. For dry skin that loses moisture faster than it holds it, the full-depth approach is the logical formulation answer.

🌙 Yuki's Note: Molecular weight in hyaluronic acid - the size of the molecule determines where it goes. High-molecular HA stays at the surface and creates a film. Low-molecular HA penetrates to deeper skin layers. Using multiple forms simultaneously means the formula is not choosing between surface and depth - it is addressing both.

Will this work under makeup without pilling?

ANUA specifically designed and tested this for no pilling under makeup. The gel-cream texture absorbs fully without leaving a tacky surface, which is the mechanical reason it does not interfere with product applied over it. The formula is suitable for AM and PM use as the final skincare step. For sensitive skin that changes products frequently enough to notice pilling as a pattern, a formula designed to address this specifically is a relevant detail.

Is niacinamide in this formula a concern for sensitive skin?

Niacinamide appears in the ingredient list. At typical cosmetic concentrations it is generally well-tolerated, including by sensitive skin, and it contributes to the skin tone-evening and texture-refining effects alongside the hydration complex. Niacinamide sensitivity is real but uncommon - flushing or redness reactions are occasionally reported at high concentrations. For sensitive skin encountering niacinamide for the first time in a formula, patch testing is the sensible first step.

🌙 Yuki's Note: Niacinamide - vitamin B3. Studied for a range of skin benefits including improving skin texture, supporting barrier function, and mild brightening over time. Generally considered one of the more well-tolerated active ingredients in skincare.

Worth Knowing

If Your Skin Tightens Throughout the Day Despite Moisturising: The 100-hour dermal hydration result from clinical testing suggests the formula is building lasting moisture retention rather than delivering a single-application effect. For skin that rehydrates at the basin and tightens again by afternoon, sustained delivery at multiple depths - which the ten-form HA complex provides - is a more effective formulation approach than surface application alone.

Squalane as the Emollient Base: Squalane appears as the second ingredient, making it a primary component of the formula's moisture-locking mechanism. It is one of the most skin-compatible emollients available, closely resembling the skin's own natural oils. For dry or sensitive skin, squalane provides barrier reinforcement without the heaviness of traditional oils or occlusive agents.

The Centella and Botanical Complex: Madecassoside, Asiaticoside, and Centella Asiatica Leaf Extract appear toward the end of the ingredient list, adding a calming and barrier-supportive layer to what is primarily a hydration formula. For sensitive skin that tends toward redness or irritation, these are familiar and well-evidenced soothing ingredients working quietly in the background.

Suitable for Breakout-Prone Skin: Non-comedogenic tested. The lightweight gel-cream texture and the absence of heavy occlusive ingredients mean the formula is designed not to block pores, which is relevant for anyone who typically avoids cream moisturisers due to congestion concerns.

Something about a formula this quietly constructed makes it easy to trust. No fragrance. No colour. Just the hydration doing the work at every depth it can reach. Applied at night, absorbed before the lights go off. That is the whole of it. 🌙
