Dr.Reju-All PDRN Copper Peptide Serum for Face — GHK-Cu + Hyaluronic Acid, 1.01 fl oz, Lightweight Firming

This serum was formulated in Korea by doctors and pharmacists and is distributed through thousands of local pharmacies, blending targeted actives in a fast‑absorbing base suitable for everyday use. It pairs a copper peptide complex (GHK‑Cu) with PDRN to address visible signs of skin laxity and hydration loss, while humectants and collagen peptides help the skin feel smoother and more comfortable throughout the day.

How does this serum work to improve skin firmness?

The formula combines copper peptides (GHK‑Cu) and PDRN to support tissue conditioning and a firmer-looking surface. These ingredients are known in cosmetic formulations for supporting the appearance of elasticity when used consistently as part of a skincare routine.

• GHK‑Cu (copper peptide) included for skin-supportive peptide activity.
• PDRN added to support skin conditioning and refreshed appearance.
• Hydrolyzed collagen peptides contribute to a smoother skin texture feeling.
• Designed for regular application to maintain visible benefits.

Will this feel heavy or layer under other products?

The serum has a lightweight, fast‑absorbing texture intended for daily layering, including under moisturizers and sunscreens. It is formulated to sit comfortably on skin without a greasy residue, making it suitable for AM and PM routines and warmer climates.

• Fast absorption for easy double‑layering with creams or oils.
• Non‑oily finish that works under makeup and SPF.
• Suitable for both morning and evening application.

Is this serum appropriate for sensitive or stressed skin?

Dr.Reju-All’s formulation is described as gentle enough for daily use on all skin types, including sensitive skin. It aims to comfort skin stressed by environmental factors while minimizing irritation when used as directed.

• Developed by healthcare professionals with safety in mind.
• Lightweight base reduces likelihood of pore‑clogging or heaviness.
• Intended for routine use on skin affected by UV, heat, or daily stressors.

How should I add this serum into my skincare routine?

Apply a few drops to clean, toned skin and gently pat until absorbed before layering moisturizer and sunscreen. Use it twice daily for consistent results, and patch test if you have heightened sensitivity to actives.

• Use after cleansing and toning, before heavier creams.
• Recommend morning and evening for steady support.
• Follow with broad‑spectrum SPF in daytime routines.
