Polynucleotides, also known as DNA or RNA, are biological macromolecules composed of nucleotide units. They are used as injectable products in aesthetic medicine, particularly in treatments aimed at skin rejuvenation and anti-ageing. The injectable form typically involves the use of polynucleotide-based solutions or gels that are injected into the skin.

The are an ideal skin treatment for people in their 30s-40s, people with rosacea, people who have mild scarring or want to improve skin texture.

They have many benefits:

1. Cellular Communication: Polynucleotides can act as signaling molecules that facilitate communication between skin cells. They may help regulate various cellular processes, such as cell proliferation, differentiation, and repair.

2. Collagen Synthesis: Some formulations containing polynucleotides claim to stimulate collagen synthesis. Collagen is a crucial protein that provides structural support to the skin, contributing to its firmness and elasticity. By promoting collagen production, polynucleotides may help reduce the appearance of fine lines and wrinkles.

3. Anti-Inflammatory Effects: Polynucleotides may possess anti-inflammatory properties, which can be beneficial for soothing irritated or inflamed skin. This anti-inflammatory action can be helpful in conditions like redness or sensitive skin.

4. DNA Repair: Theoretically, polynucleotides may contribute to DNA repair processes in skin cells. This could potentially help cells recover from damage caused by environmental factors, such as UV radiation.

5. Moisture Retention: Some skincare products containing polynucleotides claim to improve skin hydration by enhancing the skin's ability to retain moisture. This can be particularly beneficial for individuals with dry or dehydrated skin.
