Best Treatments for Scars, Stretch Marks and Cellulite

Scars, stretch marks and cellulite are all common concerns most of us experience throughout our lifetime, regardless of age, weight or fitness level. Thankfully, there are several modern and professional treatments we offer here at Aventis, which do much more than temporarily smooth the surface.

By stimulating collagen, supporting cellular repair, improving skin firmness and addressing localised fat, we can soften scars, make stretch marks less noticeable and smooth cellulite. But the key is understanding what’s causing the texture issue in the first place to treat it long-term effectively.

So, if you’re looking for the best treatments to target scars, stretch marks and cellulite, learn what we can do:

  • Scars? Remodel collagen and improve uneven texture.
  • Stretch marks? Stimulate collagen and strengthen damaged skin.
  • Cellulite? Improve firmness, elasticity and body contours.

Recommended treatments for scars

Scars form during the body’s natural healing process; when the skin repairs itself, it produces new collagen in the damaged area. When too little collagen is formed, or develops in a disorganised pattern, it results in a scar that’s raised, indented and discoloured. Professional treatment does not always remove a scar completely, but it can improve its appearance and texture, and help it blend more naturally with surrounding skin. Here are the treatments Aventis recommends:

microneedling

1. Microneedling with PRP

Collagen and growth factor-rich plasma supercharges skin to plump up depressed scars and smooth out uneven texture, and as new collagen develops, it rebuilds tissue beneath indented scars. Rather than filling or covering the scar, it encourages the skin to remodel itself from within.

  • Best for atrophic acne scars
  • Works on indented scars and surgical marks
  • Stimulates natural collagen production
  • PRP supports tissue repair and regeneration
  • Brighter, smoother complexion in weeks
  • Full scar improvements visible over several months
  • Most patients require 3-6 sessions, spaced 4-6 weeks apart

2. Polynucleotide treatments

Uses injectable salmon DNA fragments to repair tissue and stimulate collagen and elastin production, reducing scar visibility and smoothing uneven textures from acne or surgery. Working on a cellular level, the treatment stimulates fibroblasts to rebuild damaged skin structurally, making it highly effective for strengthening damaged tissue.

  • Supports skin regeneration and repair
  • Stimulates collagen and elastin
  • Effective for atrophic (depressed) acne scars, surgical scars, & burn marks
  • Results develop gradually over a few months
  • Course of 2-3 sessions over 2-4 weeks apart recommended
  • Maintenance treatments every 6-12 months

3. MOXI laser

The lunchtime laser treatment is a gentle, non-ablative fractional laser that improves mild-to-moderate acne scarring by triggering your body’s natural healing and collagen-building response to fill in depressed scars without breaking the top layer of skin. It’s especially effective at breaking down excess pigment and red or brown marks left behind by healed scars.

  • Excellent for superficial and pigmented scarring
  • Encourages skin renewal
  • Stimulates collagen production
  • Minimal downtime/flaking for 2-5 days
  • Improvement seen after one session
  • Series of 3-4 treatments for best scar reduction results

4. Medical-grade chemical peels

Medium-depth trichloroacetic acid (TCA) treats scars by removing damaged skin layers, stimulating collagen, and encouraging healthier cells to rise to the surface. Superficial peels like Glycolic or Salicylic acid can address mild scarring, rough texture, and post-inflammatory hyperpigmentation. TCA CROSS (Chemical Reconstruction of Skin Scars) applies high-concentration TCA into deep ice pick scars to trigger heavy collagen production.

  • Removes damaged surface cells
  • Effective for acne scars (rolling or boxcar scars)
  • Good for superficial scarring and post-inflammatory pigmentation
  • Lighter peels improve mild discolouration with limited downtime
  • Stronger formulations can reach deeper layers of damaged skin
  • Visible flaking may occur

stretch marks

Recommended treatments for stretch marks

If the skin stretches or changes more quickly than collagen or elastin fibres can adapt, it can result in stretch marks, which typically appear during pregnancy, puberty, growth spurts and weight fluctuations. They are permanent changes within the deeper layers of skin, but professional treatment can improve their colour, texture and overall visibility.

microneedling

1. Microneedling with PRP

Needles penetrate the skin to break up old scar tissue, and the PRP is absorbed directly into the micro-channels to plump and fade the targeted area. Treatment is best for patients with red or purple stretch marks. Older, white stretch marks will take longer, but will still result in an improvement in texture and depth/

  • Stimulates collagen within stretch marks
  • Improves uneven or indented texture
  • Can be used on multiple body areas
  • Suitable for newer and older marks
  • Results improve gradually
  • Course of 3-4 sessions, spaced 4-6 weeks apart

2. Polynucleotide treatments

Recommended for stretch marks that are accompanied by thinning skin and reduced elasticity, as they work within the skin to support fibroblast activity and tissue repair.

  • Supports damaged or weakened skin
  • Improves elasticity and hydration
  • Stimulates collagen and elastin
  • Works alongside microneedling or laser
  • Requires 3-4 sessions, 2-3 weeks apart

3. MOXI laser

A gentle, fractional non-ablative laser that improves stretch marks in several treatment areas through collagen and elastin stimulation. Best for newer, red/purple stretch marks by reducing discolouration.

  • Stimulates skin renewal
  • Encourages collagen remodelling
  • Improves colour and texture
  • Makes stretch marks less noticeable
  • Remodels damaged tissue
  • Requires a series of 3-6 sessions

cellulite

Recommended treatments for cellulite

Cellulite creates dimpled, rippled or uneven surfaces that can be caused by genetics, hormones, circulation, fat distribution, collagen loss and skin thickness, which is why it’s common and affects people of every body type (even those who exercise regularly and maintain a stable weight).

1. Aqualyx fat-dissolving treatment

An injectable that dissolves stubborn localised fat that can cause skin dimpling, offering a modest cosmetic improvement by reducing fat deposits. Aqualyx uses deoxycholic acid, a natural bile acid, to rupture fat cell membranes, which breaks down fat cells that are then naturally flushed out of the body via the lymphatic system.

  • Best for small pockets of stubborn fat
  • Non-surgical injectable treatment
  • Gradually breaks down fat cells
  • Results are permanent if weight is maintained
  • Typically 30-60 minutes per session
  • Patients often require 2-4 sessions, spaced 4-6 weeks apart

2. SkinTyte laser

Advanced infrared light deeply heats the dermis, prompting new collagen production and contraction to firm the skin and soften the appearance of cellulite on the thighs and abdomen. As SkinTyte is not a direct cure for cellulite, as it does not remove fat or release fibrous bands, it’s often combined with other procedures for more comprehensive cellulite reduction.

  • Best for cellulite accompanied by loose skin
  • Addresses mild-moderate skin laxity
  • Uses non-invasive infrared energy
  • Stimulates collagen production
  • Tighter, thicker, firmer skin in 3-4 months
  • No downtime (it’s like a warm massage)

3. Profhilo Body

An injectable hyaluronic acid bio-remodeler that can treat cellulite by hydrating the skin, stimulating collagen and elastin production and firming loose skin. As it thickens and smooths the skin, it can help disguise dimpling and the “orange peel” texture.

  • Best for loose, crepey or dehydrated skin
  • Stimulates collagen and elastin
  • Minimal downtime
  • Used on the face, body and areas like arms and knees
  • Two treatments required one month apart

3. Polynucleotide treatments

Injectable biostimulators that use purified DNA/RNA fragments to repair and regenerate loose skin by improving thickness, elasticity and collagen production that can smooth out the dimpled, uneven texture characteristic of cellulite. When the skin loses strength and thickness, fat deposits push through, creating visible dimples. Polynucleotides rev up fibroblast activity to fight this.

  • Supports regeneration and tissue repair
  • Improves hydration and elasticity
  • 3-4 sessions required,d spaced 2-4 weeks apart
  • Typically used on the thighs or buttocks
  • Visible improvements within 4 weeks
  • Results last 6-12 months, maintenance required every 6-9 months
