Curenex USA offers a wide range of skincare and cosmetic products that primarily contain PDRN and peptide complexes, which provide a whole new level of skin rejuvenation and healing effects.
K Derma Co., Ltd in Seoul, South Korea, pioneered the creation of the skincare brand Curenex by incorporating skin-boosting ingredients such as PDRN, collagen, and peptide complexes, which are the primary focus of their R&D efforts.













PDRN, or polydeoxyribonucleotide, is extracted from salmon DNA and has been proven to promote the regeneration of skin cells and protect the skin barrier from further damage. It aids in the skin’s cell viability and strengthens the extracellular matrix formation (ECM). Its primary use is in the treatment and repair of damaged skin tissues before it was used in cosmetic products. Hence, it is highly effective as an anti-aging ingredient. Sometimes it is labelled as sodium DNA in cosmetic products.

It is often used interchangeably with PDRN as they have similar properties, however they differ in composition, size, structure, source, and function; where polynucleotide is derived in both DNA and RNA sources and is broadly used for its regenerative properties, hydration, and skin rejuvenation effects.

It mainly comprises of growth factors such as copper peptides, tripeptides, and palmitoyl pentapeptide. Multi-peptide complexes primarily stimulate collagen production, keeping the skin youthful and void of fine lines and wrinkles.

Glutathione’s main function is an antioxidant, in which it removes free radicals and efficiently detoxifies the body from harmful toxins. Although it is naturally produced in the body, the glutathione levels can deplete with age, sun exposure, and pollution. Hence, it is important to maintain a skincare routine by adding products with glutathione. It primarily has skin-brightening properties as it reduces pigmentation and helps even out the skin tone. Also, it has anti-aging benefits, further protecting the skin from oxidative stress and environmental damage.

Niacinamide or Vitamin B3 helps improve the skin barrier function, reduces inflammation, and regulates oil production. It is also known for reducing redness, calming irritated skin and has significant effects on pore reduction. It is also excellent in fading hyperpigmentation, dark under eyes, and acne scars. Moreover, it serves as a skin barrier support, hence improving the overall skin health while also balancing the hydration levels and oil/sebum production of the skin.

Collagen is the most abundant protein found in the skin which provides structure, strength, and elasticity. As the skin ages, it affects the levels of collagen present in the skin, hence it shows in the form of wrinkles, fine lines, and sagging skin. By stimulating the production of collagen in the skin, it helps restore the skin’s elasticity and firmness, producing amore youthful appearance. While it restores the skin firmness, it also provides hydration to the skin.

PDRN or polydeoxyribonucleotide have been proven to have significant effects on wound healing by promoting angiogenesis (formation of new blood vessels) and improving the blood circulation to the damaged ones. It also triggers fibroblast activity, which in turn increases the production of collagen and elastin to maintain the skin’s structure and firmness.
Furthermore, PDRN in skincare products activates the A2A Adenosine receptors, modulating the inflammatory response. Thereby, soothing irritated skin and calming inflammation which makes it helpful for treating various skin conditions such as acne, eczema, and post-treatment redness.
Since PDRN is composed of nucleotides, it can aid in DNA repair within the skin cells. through the salvage pathway, PDRN promotes the regeneration of skin cells, restoring damaged DNA and creating a healthier and more resilient skin. It also has anti-oxidant properties, which protects the skin from further damage caused environmental factors or by free radical which often accelerates skin aging.
