What do you mean that this was after only ONE session of polynucleotides 👀
Unlike filler, polynucleotides don’t add volume. Instead, they work by improving the quality of the skin itself.
🧬 The science:
Polynucleotides are purified DNA fragments that act as powerful biostimulators. Once injected, they encourage your skin’s own repair processes by:
✨ Stimulating fibroblasts to produce more collagen and elastin.
💧 Improving hydration by supporting the skin’s extracellular matrix.
🩸 Promoting angiogenesis (the formation of tiny new blood vessels), which can improve microcirculation and oxygen delivery to the tissue.
🔄 Helping tissue repair while reducing oxidative stress and inflammation.
How does this help dark under eyes?
Dark circles can have many causes, so no treatment is one-size-fits-all. But if your darkness is related to thin, crepey skin or poor skin quality, polynucleotides can help by:
✔️ Thickening and strengthening the delicate under-eye skin, making underlying blood vessels less visible.
✔️ Improving skin texture and elasticity.
✔️ Supporting healthier microcirculation, which may reduce the dull, tired appearance in some people.
✔️ Enhancing hydration for a smoother, brighter-looking under eye.
The result isn’t an instant change, it’s gradual skin regeneration over several weeks, with improvements continuing as new collagen forms. Think of it as improving the skin rather than simply filling it.
Results vary depending on the cause of your dark circles. If pigmentation, genetics, or volume loss are the main cause, other treatments may be more appropriate. Book a consultation through the link in bio.
