Peter Thomas Roth Peptide Skinjection Amplified Wrinkle-Fix Serum — Refillable Pump, High-Peptide Complex

Peter Thomas Roth Peptide Skinjection™ Amplified Wrinkle‑Fix Serum is a refillable, needle‑free peptide serum formulated to help visibly reduce expression lines and support firmer, smoother‑looking skin.

This advanced serum combines multiple concentrated peptide technologies in a lightweight, refillable delivery system to target the appearance of dynamic expression lines and signs of loss of firmness. Designed for daily use on all skin types, the formula layers easily under moisturizers and makeup and can be used alone or as a complementary step after in‑office treatments. The product blends several peptide actives with supportive ingredients to deliver a clinically studied peptide profile in a convenient pump and refill format.

How does this serum address expression lines without needles?

The serum uses a high total peptide loading to target muscle movement–related lines and support skin’s surface appearance. Peptides in the formula are selected to act on pathways related to expression lines and skin architecture, helping the skin appear smoother with repeated application.

• Contains a 19% peptide complex including Matrixyl Morphomics, Argireline Amplified, and Matrixyl Synthe’6.
• Includes 10% Argirelox™ peptide solution to extend aesthetic outcomes reported in formulation studies.
• Lightweight, fast‑absorbing texture suitable for under makeup and other products.

What results were observed in clinical testing and how should I set expectations?

Clinical assessments reported improvements in the look of expression lines with regular twice‑daily use; results vary by individual and routine. The serum is intended to visibly reduce the appearance of existing expression lines and help prevent the look of future lines when used consistently as directed.

• Formulation supported by in vivo peptide studies; individual outcomes depend on factors like age and skin condition.
• Best results seen with consistent twice‑daily application as part of a complete skincare routine.
• Can be used to complement in‑office injectables or as a non‑invasive alternative between treatments.

How do I use the refillable system and layer it with other products?

The serum is packaged in a refillable pump designed for daily dosing. Apply to clean, dry skin on areas of concern, allow it to absorb, then follow with moisturizer and sunscreen in the morning or richer creams at night.

• Pump 1–2 doses onto fingertips and smooth over forehead, around eyes, and other expression areas.
• Use morning and evening; allow a few moments to fully absorb before layering additional products.
• Refill cartridges are available to reduce waste and maintain consistent dosing.

Are there skin types or sensitivities to consider before using this serum?

The formula is created for all skin types, including those seeking peptide‑based anti‑aging support. As with any potent active product, patch testing is recommended for very sensitive skin, and discontinue use if irritation occurs.

• Suitable for normal, dry, combination, and oily skin when used as directed.
• Patch test behind the ear or on the inner forearm for 24 hours if you have reactive skin.
• Avoid contact with eyes; if irritation develops, stop use and consult a skincare professional.

Who is this for: Peter Thomas Roth Peptide Skinjection™ Amplified Wrinkle‑Fix Serum is aimed at anyone seeking a non‑invasive peptide treatment to visibly reduce the appearance of expression lines and support firmer‑looking skin. It’s appropriate for users who prefer a refillable, science‑forward product that integrates into a daily routine, those looking to complement periodic professional treatments, and people who want targeted peptide actives packaged in a convenient pump system.
