Improve your skin quality from our premium range of skin booster treatments at L’Atelier Aesthetics on Harley Street.
Performed by Dr Duncan Brennand within our L’Atelier Aesthetics clinic at 101 Harley Street. Skin boosters are a doctor-led treatment that revitalise the skin from within. They are great at improving hydration, texture, and firmness for a naturally refreshed appearance.
Skin boosters are injectable treatments that use hyaluronic acid, a naturally occurring molecule in the skin responsible for maintaining moisture and structure. Over time, our natural hyaluronic acid levels decline, leading to dullness, dehydration, and loss of elasticity.
Skin boosters work to:
Improve hydration and luminosity
Soften fine lines and wrinkles
Increase elasticity and firmness
Smooth uneven or crepey skin texture
Reduce dullness caused by ageing or environmental stress
Revive skin health for a more radiant, youthful glow
They’re suitable for all skin types and can be used on the face, neck, décolletage, and hands, anywhere the skin needs extra vitality.


Skin boosters are administered through a series of micro-injections using ultra-fine needles. The hyaluronic acid spreads evenly beneath the skin, attracting water molecules and improving elasticity and texture.
The treatment works in two phases:
Immediate hydration boost, plumper, smoother skin within days.
Long-term regeneration, increased collagen and elastin production for lasting improvement over the following weeks.
While both treatments involve injectable solutions, skin boosters and dermal fillers work in completely different ways. Dermal fillers are designed to restore volume and structure, using a thicker form of hyaluronic acid to lift and define areas such as the cheeks, lips, and jawline.
In contrast, skin boosters focus on improving skin quality rather than adding volume, delivering lightweight hyaluronic acid or regenerative ingredients like Polynucleotides evenly across the skin to boost hydration, elasticity, and radiance. The result is smoother, healthier-looking skin with a natural glow, rather than a change in facial shape or contour.


Dr Duncan Brennand is our lead Aesthetic Physician at L’Atelier with a wealth of expertise in both innovative and evidence-based treatments.

A skin booster is a lightweight hyaluronic acid injectable designed to deeply hydrate and rejuvenate the skin without adding volume.
Polynucleotides are a new generation of regenerative skin boosters that go beyond hydration to repair and rejuvenate the skin at a cellular level.
Unlike traditional hyaluronic acid skin boosters, which primarily focus on moisture and glow, Polynucleotides work to detoxify and restore the skin’s natural balance. Derived from purified DNA fragments, they stimulate fibroblast activity to boost collagen and elastin production while neutralising free radicals, which are the unstable molecules that accelerate ageing.
This double action helps to regenerate the skin, improve elasticity, and enhance overall skin quality, leaving the complexion clearer, firmer, and more rejuvenated.
They deliver hyaluronic acid into the skin using micro-injections, improving moisture levels, elasticity, and texture from within.
They enhance hydration, boost collagen production, and leave the skin glowing, smooth, and refreshed.
Most people notice visible results within 1–2 weeks, with continued improvement as collagen and elastin increase.
Results usually last between 6–9 months, depending on the individual, the product and treatment area.
At our 101 Harley Street location you will need a course of two treatments, three to four weeks apart, is recommended initially, followed by maintenance every six months.
HA or Dermal Fillers restore volume and structure, whereas skin boosters improve skin quality, hydration, and elasticity.
