Celimax Retinol Shot Tightening Serum - 30ml

What It Is & Key Ingredients

• Brand & Name: Celimax — The Vita-A Retinol Shot Tightening Serum, 30 ml. 

• Retinol Concentration: 0.1% pure retinol.

• Peptide Complex: 9 different functional peptides to support skin elasticity and firmness. 

• Panthenol (1%): For hydration and skin barrier support. 

• A-Shot™ Technology: Uses very fine micro-particles (much smaller than pores) to help deliver retinol deeper into the skin, improving absorption and reducing irritation. 

• Other Ingredients: According to the official ingredient list: water, glycerin, sunflower seed oil, beta-carotene, peptides (Tripeptide-1, Palmitoyl Tripeptide-1, Nonapeptide-1, Hexapeptide-9, Dipeptide-2, Copper Tripeptide-1, Acetyl Tetrapeptide-5, Acetyl Hexapeptide-8, Palmitoyl Pentapeptide-4), allantoin, adenosine, and more. 

What It’s Good For / Benefits

• Wrinkles & Fine Lines: Retinol helps stimulate skin renewal and collagen production, targeting early signs of aging (wrinkles). 

• Firmness & Elasticity: The peptide complex helps improve skin elasticity and firmness.

• Pore Minimization: The A-Shot™ micro-particles help deliver actives into pores, which can help refine them.

• Smoother Texture: Helps with uneven texture due to cell turnover.

• Skin Barrier Support: With 1% panthenol, it’s not just active but somewhat caring — helps reduce retinol irritation. 

Possible Drawbacks / Precautions

• Tingling / Sensation: Because of retinol + micro-particles (A-Shot™), some tingling or mild stinging is expected.

• Retinol Irritation Risk: As with all retinol products — skin may purge, peel, or become sensitive. > > “Starting at 0.1% … purging badly … you need the smallest of dabs … Too much … will irritate your skin.” (

• Sun Sensitivity: Use sunscreen the morning after retinol application, because retinol increases sensitivity to UV. 

• Frequency of Use: For beginners, Celimax recommends using it every other night for the first two weeks, then gradually increasing. (

• Cost / Authenticity: As with many K-beauty actives, buy from trusted retailers to ensure you’re getting a real product.

How to Use It

1. Night-time Use: Apply in the evening (retinol should be in your PM routine). 

2. Start Slowly: Use a small amount (a “pea-size” or less) on first use; for the first 1–2 weeks, use it every other night. 

3. Apply Gently: After cleansing (and possibly toning), apply the serum to your face.

4. Moisturize: Follow with a gentle moisturizer to buffer the retinol if needed.

5. Use Sunscreen in the Morning: The next day, always apply SPF as the final step.
