✨ Heavy-duty skin repair for body areas that need more than a facial-grade treatment.
✅ How it works:
Plenhyage Body floods your skin with purified DNA fragments from fish that wake up your own repair cells. It forces your body to build fresh collagen and elastin from the inside out, thickening and strengthening skin that has become thin, crepey or damaged.
✅ Who it's for:
Anyone with loose, crepey skin on inner arms, thighs, knees or hands
People with stretch marks or acne scars they want to fade from within
Those with significant sun damage or deep wrinkles on the body, not just the face
✅ The benefits:
Skin looks thicker, firmer and more resilient over time
Stretch marks and scars gradually soften and blend
Deep wrinkles and creases become less noticeable
Skin bounces back instead of staying slack
Results look natural because they're built from your own collagen
✅ What's included:
A full consultation to map your treatment areas
Numbing cream applied before we start
Multiple tiny injections across the area with fine needles
The strongest Plenhyage formula (25mg/ml) specifically for body skin
Aftercare guidance and a plan for your full course
✅ What to expect:
3 to 4 sessions, spaced 3 to 4 weeks apart
First visible changes around 3 weeks in
Peak results at about 5 months
Lasts 6 to 9 months, depending on your skin and lifestyle
💡 This is the treatment Bella reaches for when facial-grade boosters simply aren't strong enough for the job.
Common questions
Is there any downtime?
You'll usually have small raised bumps at the injection points for a few hours and some redness or tenderness for a day or two. Most people carry on normally but skip makeup over the area for the first day.
Does it hurt?
It's quite manageable — we put numbing cream on first, so most people feel brief pressure or mild stinging rather than anything sharp. Body skin is thicker than facial skin, which helps.
How many sessions will I need?
Most people need a course of 3 to 4 sessions, spaced 3 to 4 weeks apart. If you've got a wedding, holiday or big event coming up, it's worth starting at least 12 weeks beforehand so everything's settled in time.
How long do the results last?
You'll typically start noticing a difference around 3 weeks, and it's at its best at about 5 months. From there it usually lasts 6 to 9 months, depending on your skin condition, age and lifestyle.
Are there any side effects?
It's normal to have some redness, tenderness, small bumps at injection points and the odd bruise for a day or two afterwards. These settle on their own. Rarely, people with sensitive skin can have a reaction to fish-derived products.
Preparing for your appointment
Avoid alcohol for 24 hours before — it thins the blood and increases bruising
Stop retinol and strong active skincare 3 days prior
Come with clean skin, no makeup or lotion on the treatment area
Eat normally and stay hydrated — no need to fast
Let us know if you take blood-thinning medication or have a bleeding disorder
After your treatment
Expect small bumps at injection points — these settle within hours to a day
Mild redness, tenderness and possible bruising is normal for 24 to 48 hours
No makeup over injection sites for 12 to 24 hours
Skip the gym, saunas, hot baths and alcohol for 24 hours
Keep the area clean and avoid touching — let the product settle naturally
Do not book if
You have any allergy to fish or fish-derived products
You are pregnant or breastfeeding
You have an active skin infection or inflammation where you want treated
You have an autoimmune condition affecting your skin
You take anticoagulant medication or have a bleeding disorder
You want immediate volume or contour change — this is not a filler
