What is Julaine?

Once injected, it works deep within the dermis to activate your skin’s natural collagen production, improving texture, elasticity, and firmness gradually over time.

Julaine’s key benefits include:
Stimulates collagen for firmer, smoother skin
Restores natural facial contours and volume
Improves texture, tone, and elasticity
Subtle, progressive results that enhance over time

Both Julaine and Sculptra are PLLA-based collagen stimulators designed to boost natural collagen. However, Julaine has been developed using next-generation purification and particle technology to offer a smoother injection experience, faster preparation, and greater precision. Many patients report a more comfortable treatment and a refined, natural finish. Remember with all treatments at L’Atelier we will insist upon a thorough consultation, to ensure the treatment is tailored to your needs.
Julaine contains poly-L-lactic acid (PLLA), a biocompatible material that stimulates your skin to produce collagen naturally.
Yes, both are collagen stimulators, they support your body to produce new natural collagen. However, Julaine uses an enhanced formulation of PLLA designed for improved precision, consistency, and comfort. This process is anti / non-inflammatory approach thanks to its innovative formulation compared to Sculptra that produces an inflammatory response to stimulate your body’s own collagen.
Collagen stimulation begins gradually, with results becoming visible within 6–12 weeks after treatment, however you may start to see improvements in skin quality quicker then this.
Results can last up to 24 months, depending on your skin and treatment plan.
No, Julaine isn’t a traditional HA or Dermal filler. Unlike hyaluronic acid (HA) fillers that provide instant volume, Julaine stimulates your body’s own collagen to improve structure over time.
Typically 2–3 sessions are recommended, spaced 4–6 weeks apart, for optimal collagen stimulation and longevity. Many common treatment areas include the cheeks, jawline, temples, and lower face to restore lift and contour.
At our L’Atelier Aesthetics clinic at 101 Harley Street, Marylebone, we charge from £1200 for Julaine treatments. A single treatment will cost from £1200 whilst a course of 3 treatments will cost £3000.

Dr Duncan Brennand, Medical Director at L’Atelier Aesthetics, is a highly experienced aesthetic doctor based on Harley Street. With an extensive background in non-surgical rejuvenation and a commitment to natural outcomes, Dr Duncan is trusted for his artistry, precision, and medical integrity.
Before treatment, the skin is cleansed and a numbing cream or local anaesthetic is applied to ensure complete comfort. Julaine is then prepared for precise, even injection using advanced micro-cannula techniques to minimise bruising and optimise results.
The Julaine treatment generally takes 30 minutes, during which small amounts of Julaine are placed strategically beneath the skin. Julaine’s unique LASYNPRO technology, using highly uniform microspheres, stimulates the body’s own collagen to gradually restore structure, firmness, and luminosity.
There’s minimal downtime, you may experience light swelling or redness for 24–48 hours. Dr Brennand will provide detailed aftercare guidance, including gentle massage techniques to ensure smooth, even distribution.
As your skin’s own collagen gradually regenerates, fine lines soften, contours re-emerge, and luminosity returns without the look or feel of traditional filler.
Results develop progressively over 6–12 weeks, revealing firmer, smoother skin with authentic radiance. The photographs below demonstrate the natural improvement achieved after one or two sessions, reflecting the subtle yet transformative effect of Julaine when performed by an experienced practitioner like Dr Brennand.
Julaine is a collagen-stimulating injectable designed to rejuvenate skin from within for subtle, natural-looking results. At L’Atelier Aesthetics it is performed by Dr Duncan Brennand, with minimal downtime for most patients. You may notice mild redness, swelling, small bumps or bruising at the injection sites, which typically settles within a few hours to a few days.
Because Julaine works by activating your own collagen production, results are progressive rather than instant. Collagen regeneration develops gradually over the weeks after treatment, and your outcome continues to improve as the skin strengthens and smooths.
