A concentrated serum designed to energize, hydrate, and visibly renew depleted or aging skin at the cellular level.

Formulated with a potent blend of Nicotinamide Mononucleotide (NMN - 4,000PPM) and Nicotinamide Adenine Dinucleotide (NAD⁺ - 4,000 PPM), this advanced treatment supports skin longevity by fueling the essential processes behind repair, resilience, and radiance. Sodium Hyaluronate deeply replenishes hydration, while Glycerin and Butylene Glycol work to reinforce the skin barrier and lock in lasting moisture.

While NAD⁺ is a powerful coenzyme, its relatively large and hydrophilic structure limits deep skin penetration. To overcome this, our formula features NMN, a smaller, more skin-permeable precursor that is readily converted into NAD⁺ once absorbed by skin cells. This allows the serum to effectively energize skin from within, supporting cellular regeneration and optimal function.

By combining both surface-level NAD⁺ with cell-permeating NMN, this dual-delivery system provides multi-dimensional benefits: antioxidant defense and barrier support on the outside, with true cellular rejuvenation from within. The result is visibly smoother, brighter, more resilient skin—supported from every layer.

With a lightweight, fast-absorbing texture, this serum is ideal for addressing signs of aging, environmental stress, or post-treatment recovery.

Part of the Youthplex line, the Face Lift Serum contains Volufiline, a patented ingredient derived from plant sources and a popular ingredient in anti-aging and body contouring products.

In addition, this anti-aging powerhouse contains a unique blend of peptides, including Acetyl Hexapeptide-8, Copper Tripeptide-1, and Palmitoyl Pentapeptide-4, to help rebuild collagen and elastin.

It’s an ideal serum for home use following professional anti-aging treatments.

KrX's Premium Undereye Solution is a concentrated ampoule designed to target dark circles, puffiness, and loss of volume around the eyes. Its peptide-rich formula revitalizes the delicate under-eye area, leaving skin tighter, lifted, and visibly refreshed.

Hyaluronic acid delivers deep hydration and plumps the skin to soften fine lines. Beta-glucan enhances repair by stimulating collagen and elastin synthesis while supporting skin’s protective barrier. A peptide complex, including tripeptide-41, oligopeptide-61, and oligopeptide-73, works to brighten and even tone, accelerate healing, and improve resilience in the under-eye area.

This advanced solution supports circulation and encourages lymphatic drainage, helping to reduce puffiness and discoloration. With consistent use, it improves elasticity and smoothness, restoring a youthful appearance to fatigued eyes. Recommended for integration into nano-needling or needling treatments, it maximizes both immediate and long-term results.

5 ampoules x 1.5ml

Best used with nano-needling or electroporation, the KrX Threadfill Ampoule offers a non-invasive approach to softening fine lines and wrinkles. This advanced serum features absorbable micro-collagen fibers and skin-supportive botanical extracts to improve texture and deliver intense hydration, resulting in visibly smoother, more refined skin.

The micro-collagen threads are visible within the solution but dissolve instantly upon contact with the skin or when gently massaged into targeted areas. Results are especially noticeable in expression-prone areas such as the forehead, crow’s feet, and smile lines.

For enhanced results, pair with advanced treatments such as KrX Carboxy Therapy or KrX V-Lift.

Polydeoxyribonucleotide (PDRN – 9,300 ppm), often referred to as Salmon DNA, is a regenerative ingredient derived from salmon DNA fragments. In Korean skin therapy, PDRN is known as “the healer” for its ability to support intensive skin repair and recovery at the cellular level.

Designed for use with microneedling or nano-needling, this anti-inflammatory formula helps accelerate skin regeneration, improve barrier function, and boost collagen synthesis. It is especially effective for improving the appearance of acne scars, stretch marks, post-inflammatory hyperpigmentation, and overall skin texture.

The formula is further enhanced with niacinamide, which strengthens the skin barrier, supports moisture retention, and helps visibly improve tone and fine lines, and a blend of advanced peptides—including Copper Tripeptide-1, Palmitoyl Pentapeptide-4, Tripeptide-1, and Palmitoyl Tripeptide-1—to support elasticity, repair, and skin resilience.
