Description

A needle-free peptide serum for expression lines and glass skin radiance

Size: 30 mL / 1 fl. oz.

Suitable for all skin types and tones, including dry, normal, oily, combination, sensitive, aging, and fine lines & wrinkles.

Targeted concerns: Expression lines, fine lines, wrinkles, uneven texture, enlarged pores, dehydrated skin

 

P-TIOX is a high-performance, needle-free peptide serum clinically proven to outperform standard peptide-based formulas for advanced wrinkle correction. Powered by an amplified Argireline complex, and enhanced with niacinamide, PHA, and Laminaria Extract, this lightweight serum targets 9 types of expression lines—including areas typically untouched by injectables. It visibly smooths, firms, and refines skin texture, while revealing a radiant, glass-like finish. Suitable for all skin types, including sensitive, P-TIOX is ideal both as a stand-alone anti-wrinkle solution and as a complement to neuromodulator injections.

    P-TIOX: Frequently Asked Questions

    Is P-TIOX a replacement for professional neuromodulator injections?

    While P-TIOX is incredibly powerful, no topical serum can entirely replace professional neurotoxin injections. Instead, P-TIOX acts as the ultimate 'injectable extender.' It complements your in-clinic treatments by targeting dynamic lines in areas where needles often aren't used (like cheek folds, under-eyes, and the neck), while prolonging the life of your injectables.

    What exactly is the 'Glass Skin' effect?

    Glass skin refers to a complexion so smooth, clear, and intensely hydrated that it appears almost transparent and reflective like glass. P-TIOX achieves this by pairing peptides with 5% Polyhydroxy Acid (PHA) to gently polish away dead cells, and 5% Niacinamide to shrink pores, leaving a flawless, glowing surface.

    Can I use P-TIOX if I don't get injectables?

    Absolutely! It acts as a phenomenal needle-free alternative for anyone looking to treat expression lines, deep wrinkles, and textural dullness without stepping into a medical clinic.

    What are the 9 types of contraction lines it targets?

    Clinical studies show P-TIOX visibly reduces: 1) Forehead lines, 2) Glabellar lines ('11s' between the brows), 3) Crow's feet, 4) Under-eye wrinkles, 5) Cheek folds, 6) Nasolabial folds (smile lines), 7) Marionette lines, 8) Dynamic lip lines, and 9) Neck lines.

    Can I use P-TIOX in the same routine as Retinol and Vitamin C?

    Yes, P-TIOX is highly synergistic. In the morning, apply it after your Vitamin C (C E Ferulic) and before sunscreen. At night, it can safely be applied before or after your Retinol to boost anti-aging benefits without causing irritation.

    How does the Advanced Peptide Complex work?

    The proprietary blend of Hexapeptide and Dipeptide works topically to interfere with the neurotransmitter signals that tell facial muscles to contract. By 'relaxing' this signaling on a surface level, the skin creases less, allowing dynamic wrinkles to soften and fade over time.

    Is P-TIOX suitable for sensitive or rosacea-prone skin?

    Yes. Because it uses PHA (Polyhydroxy Acid) instead of stronger AHAs like glycolic acid, it provides necessary exfoliation and texture refinement without triggering redness or stinging. The 5% Niacinamide also actively calms the skin barrier.

    How quickly will I see results with P-TIOX?

    You will see a visible improvement in skin radiance, texture, and the 'glass skin' finish within the very first week. Significant clinical reduction in deep contraction lines is scientifically proven after 12 weeks of twice-daily use.
