The THOME CPR Serum is a Korean retinal serum where every letter in CPR stands for something — Collagen 1%, Peptide 1%, Retinal 0.1%. Three powerhouse actives at published concentrations, formulated together as a triple-synergy system.

The Retinal is encapsulated in micro-capsules that keep it fresh and deliver it evenly with every drop. Dual-Cushion Collagen cushions your skin during the retinal adjustment period so you get the results without the peeling and dryness most retinal users dread. Designed to target 10 wrinkle zones across the full face

• Retinal 0.1% — The "R" in CPR — Retinal converts to the active form one step faster than Retinol, so you see results sooner. Micro-capsule technology keeps it fresh and stable until the moment it touches your skin. Start 2–3 nights per week and build up gradually.
  
• Dual-Cushion Collagen 1% — The "C" in CPR — two molecular weights of Collagen that cushion and plump your skin while the Retinal does its job. This is what keeps you from getting the dryness and flaking.
  
• Peptide Complex 1% — The "P" in CPR — a firming peptide complex that supports skin density and bounce independently while boosting what the Retinal is already doing. Three actives amplifying each other — that's the triple synergy.
  
• Astaxanthin + Polyglutamic Acid + Adenosine — Supporting Cast — Astaxanthin is one of nature's strongest antioxidants, protecting skin while it's turning over from the Retinal. Polyglutamic Acid holds 4x more moisture than regular HA. Adenosine smooths fine lines.

⚠️ Contains Retinal (Retinaldehyde). PM use only. Do not use during pregnancy or while breastfeeding. Follow with SPF the next morning. Start 2–3 nights per week and increase gradually. Fragrance-free. 30ml.
