Rimyoi Copper Peptides Serum — 3% GHK‑Cu, 1 fl oz lightweight daily serum for firmer-looking, hydrated, smoother skin

Designed to sit comfortably in morning and evening routines, this 1 fl oz serum combines a concentrated 3% GHK-Cu copper peptide blend with supporting ingredients—niacinamide for balanced tone and panthenol for hydration—to help skin appear more refined, supple, and comfortable. The fast-absorbing formula layers easily under moisturizers or sunscreen and is made for everyday use across a wide range of skin types.

How will this serum fit into my morning and evening routine?

Apply the serum after cleansing and any lightweight water-based treatments, then follow with moisturizer and SPF in the morning or a richer cream at night. Because it absorbs quickly and feels non-greasy, it works well under makeup and pairs with most other actives.

• Use 2–3 drops across face and neck, morning and/or evening.
• Layer beneath moisturizer; allow 30–60 seconds to absorb.
• Compatible with commonly used hydrators and barrier-supporting products.

What does the 3% GHK-Cu concentration actually do for skin appearance?

The 3% copper peptide (GHK-Cu) concentration is formulated to help support the look of firmer skin and smoother texture through topical peptide delivery. It’s included to enhance the skin’s overall appearance when used consistently as part of a daily regimen.

• Targets visible texture and the look of fine lines.
• Works in tandem with niacinamide for balanced skin tone.
• Designed for daily, long-term use rather than one-time results.

Is this serum suitable for sensitive or easily irritated skin?

Rimyoi’s formula combines niacinamide and panthenol—both known for being gentle and skin-supporting—to reduce the chance of dryness or irritation. The lightweight base and rapid absorption also help minimize heavy layering, which can benefit sensitive skin types.

• Niacinamide supports skin barrier function and comfort.
• Panthenol provides hydration and a soothing feel.
• Non-sticky, low-irritation texture suitable for most skin types.

How will this serum help with hydration and tone support?

Hydration comes from the serum’s lightweight humectant base and panthenol, which helps skin feel soft and balanced. Niacinamide contributes to a more even-looking complexion, so the overall effect targets both moisture and the look of refined tone.

• Panthenol helps retain moisture for a smoother surface appearance.
• Niacinamide assists with balanced-looking skin tone and texture.
• Formula supports daily hydration without a heavy finish.

Who is this for: Rimyoi Copper Peptides Serum suits anyone looking to add a targeted peptide blend into a daily skincare routine—those aiming to support firmer-looking skin, smoother texture, and ongoing hydration. It’s formulated for morning and evening use, works well under other skincare steps or makeup, and is appropriate for people who prefer lightweight, fast-absorbing serums that layer easily with other products.
