Regen3 Complex pairs a biomimetic exosome serum with SkinPen microneedling to support firmer, smoother, better-quality skin, delivered as a short course at our Harley Street clinic with minimal downtime.
At L’Atelier Aesthetics, Regen3 Complex is one of the regenerative treatments patients ask about when they want to improve skin quality without injections. People often search for “exosome microneedling London”, “exosome facial near me” or “microneedling with serum cost” when they are ready to address texture, dullness and early laxity, and this is exactly where medical expertise matters. Regen3 Complex combines SkinPen microneedling with a biomimetic exosome serum, so the two work together to stimulate collagen and elastin. Our approach is consultation-led, personalised and always focused on natural, healthy results.

Regen3 Complex is a course of SkinPen microneedling carried out with a biomimetic exosome serum from Nouveau Visage that combines exosomes, polynucleotides and peptides. The microneedling creates fine channels in the surface of the skin while the serum is applied on top, so the two work together to support collagen and elastin and improve overall skin quality.
Patients commonly ask:
Regen3 Complex is a topical treatment used during microneedling. Nothing is injected. The exosomes are biomimetic, which means they are made in a laboratory to mimic the signalling vesicles your own cells use, rather than being taken from human or animal tissue.

Microneedling uses very fine needles to create controlled micro-channels in the outer layer of skin. This prompts a mild, controlled repair response, which is the mechanism behind standard microneedling. Regen3 Complex builds on that by applying a regenerative serum to the skin at the same time.
The serum carries exosomes alongside polynucleotides and peptides, two ingredient groups widely used in skin regeneration to support hydration, repair and collagen production. Because the serum is applied to freshly microneedled skin, more of it can reach beyond the surface than it would from a cream alone. The aim is to give the skin clearer instructions to rebuild collagen and elastin, while calming the treated area so recovery tends to be quicker and more comfortable than microneedling on its own.
Regen3 Complex is aimed at skin quality rather than volume. It is well suited to fine lines, dull or tired-looking skin, uneven texture and tone, visible pores and the early signs of skin laxity. It is used mainly on the face, and the course includes the neck so the two areas are treated together for a more even result.

Regen3 Complex uses the Newderm biomimetic exosome serums by Nouveau Visage. Each is built around the same exosome, polynucleotide and peptide base, with the formula tuned to a particular concern:
Dr Brennand will recommend which serum, or combination of serums, suits your skin at the consultation.
Regen3 Complex tends to suit you well if any of the following apply:
It may not be the right first choice in the following situations:

“Regen3 Complex suits patients who want to improve skin quality and texture without injections or significant downtime. We deliver it as a course of four sessions two weeks apart, and most patients see smoother, brighter skin from around four to six weeks as new collagen develops. If the main concern is volume loss or pronounced laxity, I will usually recommend an injectable or energy-based option instead at the consultation.”

No. With Regen3 Complex the serum is applied to the skin during microneedling rather than injected, and the exosomes are biomimetic, meaning they are made in a laboratory rather than taken from human or animal tissue. It is a topical treatment used alongside microneedling, not an injectable.
The standard course is four sessions spaced two weeks apart, so the treatment runs over about two months. Dr Brennand confirms the right number for your skin at the consultation.
Most patients find Regen3 Complex comfortable. A numbing cream is applied before the microneedling, and because nothing is injected the sensation is limited to the microneedling itself, which feels like light pressure and vibration.
