innisfree Green Tea PDRN Serum — Retinol & Hyaluronic Acid for Firming, Hydration

innisfree Green Tea Korean PDRN Serum with Retinol & Hyaluronic Acid is a lightweight, daily vegan serum that combines 56% Green Tea PDRN™ and a 1% Triple Retinol Complex to visibly firm, smooth texture, and reduce the appearance of fine lines.

This concentrated serum draws inspiration from the Korean PDRN treatment and is formulated for everyday use. Its fast-absorbing texture layers easily under moisturizer and SPF, and it blends green tea-derived PDRN with retinol and hyaluronic acid to target firmness, texture, and radiance. Clinical and instrument-based testing on a sample group showed improvements in firmness and wrinkle appearance over short-term use, supporting the formula’s performance when incorporated into a consistent routine.

How should I add this serum into my morning and evening routine?

Use the serum after cleansing and toning, applying 1–2 pumps to the full face. In the morning follow with moisturizer and SPF; at night pair with your usual moisturizer. Because it contains retinol, introduce it gradually if you’re new to retinoids and monitor skin tolerance.

• Apply 1–2 pumps to face during the serum step.
• Use AM + PM; always pair with sunscreen in the AM.
• Start with alternate nights if you have retinol sensitivity.

What key ingredients deliver results and what do they do?

The formula centers on 56% Green Tea PDRN™, a concentrated green tea-derived extract, plus a 1% Triple Retinol Complex for cell-surface renewal and hyaluronic acid for hydration. Together these act to smooth texture, improve bounce, and support the look of fine lines without feeling heavy on skin.

• 56% Green Tea PDRN™: concentrated plant-derived extract for skin texture support.
• 1% Triple Retinol Complex: targets visible lines and renewal.
• Hyaluronic acid: hydrates and plumps for a smoother surface.

What improvements can I expect and when might I see them?

Individual results vary, but testing on a small group showed early signs of firmer-feeling skin within one week and continued visible improvements over four weeks. Measurements included reductions in various wrinkle zones and improvements in perceived firmness when used consistently.

• Short-term: many users reported firmer-feeling skin within 1 week.
• Ongoing: visible reduction of fine lines and improved texture over weeks.
• Consistency: daily AM + PM use produced the best measured results.

How should I manage sensitivity and layering with other actives?

The serum is dermatologically tested and non-comedogenic, but because it contains retinol, patch testing and gradual introduction are wise. Avoid combining with other strong exfoliating acids on the same night and always follow with hydrators and SPF by day.

• Patch test before full-face use and build frequency slowly.
• Space out other potent actives (AHA/BHA) to reduce irritation risk.
• Follow with moisturizer; use sunscreen daily to protect treated skin.

Who is this for: The innisfree Green Tea PDRN Serum suits anyone seeking a plant-forward, vegan serum that supports firmer-looking, smoother skin texture and targets early fine lines. It’s designed for users willing to add a retinol-containing step to their routine—especially those looking for a lightweight, fast-absorbing product that layers well under moisturizers and SPF. If you have concerns about retinol sensitivity, start slowly or consult a skincare professional.
