COSRX Niacinamide 15% Peptide Booster Set — Amazon Exclusive duo for pore refinement, oil control & skin elasticity

COSRX Niacinamide 15% Peptide Booster Set combines a high‑strength niacinamide serum with a 6‑peptide booster toner to target excess oil, pore texture and skin elasticity.

This Amazon exclusive duo pairs COSRX’s Niacinamide 15% Serum with a Peptide Booster Toner so you can layer targeted actives without creating a complicated routine. The formulation is built for texture refinement, balanced oil control and an added peptide complex to support skin resilience. Use the products together as directed for a streamlined morning or evening ritual that focuses on smoother, more even‑looking skin.

How should I incorporate this set into my daily skincare routine?

Apply the Peptide Booster Toner right after cleansing to help the skin absorb the niacinamide serum more effectively. Pat in 2–3 pumps of the booster, then follow with 2–3 drops of the Niacinamide 15% Serum. Finish with a moisturizer and SPF in the morning, or a nourishing cream at night.

• Step 1: Cleanse thoroughly to remove makeup and dirt.
• Step 2: Pat in 2–3 pumps of the Peptide Booster Toner.
• Step 3: Apply 2–3 drops of Niacinamide 15% Serum, gently press into skin.
• Step 4: Seal with moisturizer; use SPF during daytime.

What skin concerns does the Niacinamide 15% Peptide Booster Set address?

The set is designed to refine pore appearance, help manage excess oil and improve skin radiance. Niacinamide and Zinc PCA work together to balance sebum and reduce surface texture, while the peptide booster focuses on skin elasticity and visible fine lines. The result is smoother, more even‑looking skin when used consistently.

• Refines pore appearance and overall skin texture.
• Helps control excess oil and shine with zinc PCA.
• Supports elasticity and resilience with six skin‑compatible peptides.
• Designed for layering—serum plus booster—for complementary effects.

Is this combination safe for sensitive or redness‑prone skin?

The formula aims to reduce redness and soothe texture, but high‑strength niacinamide and active peptides can be sensitizing for some people. COSRX recommends performing a patch test on the body and waiting 24 hours before full‑face use. If irritation develops, discontinue and consult a healthcare professional.

• Patch test 24 hours before facial use.
• Start with less frequent application to build tolerance.
• Layer with simple, gentle hydrating products to reduce irritation risk.
• Stop use and seek medical advice if significant irritation occurs.

How does the peptide booster enhance the niacinamide serum?

The Peptide Booster Toner delivers a targeted mix of six peptides that help support the skin’s structure and surface smoothness. When used before the niacinamide serum, it primes skin for better absorption and contributes complementary benefits—niacinamide focuses on tone and oil control while peptides support firmness and texture.

• Peptides help promote skin resilience and surface evenness.
• Prepares skin for optimal serum absorption when applied first.
• Combines oil‑balancing niacinamide with structural support from peptides.
• Effective as a two‑step, straightforward targeted treatment.

Who is this for: The COSRX Niacinamide 15% Peptide Booster Set is suited for anyone looking to refine visible pores, control excess oil and support skin firmness with a simple two‑product routine. It’s a good fit for combination and oily skin types, those with texture or uneven radiance concerns, and people who prefer targeted actives in a concise regimen. If you have very sensitive or reactive skin, begin with a patch test and introduce the products gradually.
