Skin boosters are one of the fastest-growing categories in UK aesthetics — and one of the most misunderstood. Unlike dermal fillers, they’re not designed to add volume or change facial structure. They work at a deeper level to improve the quality, hydration, and resilience of the skin itself.
What Is a Skin Booster?
A skin booster is an injectable treatment that delivers hydrating or regenerative ingredients directly into the dermis (the deeper layer of skin). The result is improved skin quality from within — better hydration, more elasticity, reduced fine lines, and a more radiant complexion — rather than structural changes to facial shape.
Profhilo
Profhilo is the most well-known skin booster in the UK. It’s a highly concentrated hyaluronic acid product that disperses throughout the tissue (rather than staying in one area like a filler) to stimulate collagen and elastin production. Administered as 5 small injections per side across the face. Usually done as a course of 2 sessions, 4 weeks apart.
- Results: improved skin laxity, texture, and hydration
- Duration: 6 months, with maintenance sessions recommended
- Best for: early-to-mid skin ageing, dehydrated skin, general skin quality improvement
Polynucleotides (PDRN/PN)
Polynucleotides (often called PN or PDRN) are a newer category of skin booster derived from purified salmon or trout DNA. They work by stimulating tissue repair and regeneration — triggering the body’s own healing and renewal processes. Popular for improving skin quality around the eyes, reducing dark circles, and overall rejuvenation.
- Results: tissue regeneration, improved skin quality and radiance
- Typically 3–4 sessions, 2–4 weeks apart
- Growing evidence base — increasingly popular in UK clinics
Are Skin Boosters Right for You?
Skin boosters suit people who want to improve their skin quality rather than change their facial structure. If you’re in your late 20s to 50s and noticing dullness, dehydration, or early fine lines, a course of skin boosters can produce meaningful, natural-looking improvements.
