Microneedling Stretch Marks at Home with PDRN | Body Stamping Routine + Results
Stretch marks are one of the most common skin concerns, especially after weight changes, pregnancy, or growth spurts. While lasers and clinical treatments can improve texture and tone, at-home microneedling—when done correctly and safely—can also support skin remodeling.
In this session, I used PDRN (polynucleotide) serum with the Channel Pro Pen (82-pin cartridge, 1mm fixed depth)to target faded stretch marks along my hips. PDRN is derived from salmon DNA and has become one of Korea’s most popular ingredients for improving elasticity and skin regeneration.

WHAT IS PDRN AND WHY IT’S USED FOR SKIN REPAIR
PDRN, short for Polydeoxyribonucleotide, is a regenerative compound extracted from salmon DNA—specifically rainbow trout in most Korean formulations. It’s structurally 99% similar to human DNA, which helps the body recognize it and stimulate repair without irritation.
Clinically, PDRN has been used in burn healing, post-laser care, and aesthetic medicine for:
- Stimulating collagen and elastin
- Improving skin density and hydration
- Reducing inflammation and promoting wound healing
When paired with microneedling, PDRN can penetrate more effectively through microchannels, supporting collagen induction therapy from both mechanical and biochemical angles.
DEVICE & DEPTH
For this routine, I used the Channel Pro Pen with the 82-pin stamping cartridge. Unlike rolling or sliding microneedling devices, stamping pens deliver vertical micro-injuries without dragging the skin. This is ideal for body areas like the hips, thighs, or abdomen where skin is thicker.
- Cartridge: 82-pin fixed 1.0mm
- Technique: Stamp only (no dragging)
- Speed: Fastest motor setting
- Serum: PDRN, layered before and during treatment
The goal isn’t to draw blood but to create visible erythema (redness), indicating collagen stimulation without tearing.
MY PROCESS
Here’s the full video walkthrough of my session:
- Draw up 3mL of PDRN serum – 1.5mL per side of hips.
- Apply a thin layer of serum before stamping.
- Stamp the skin evenly across stretch-marked zones; overlap slightly but do not drag.
- Add more serum mid-session to infuse open channels.
- Follow with topical antioxidants — I used vitamin C capsules for extra support.
- Avoid makeup, tanning, or exfoliants for at least 48 hours post-treatment.
You’ll notice mild redness for several hours, which fades as the skin tightens and smooths over the following days.

RESULTS & CONSISTENCY
The key to visible results with microneedling stretch marks is consistency. I target this area every 3–4 weeks, alternating with facial and scalp sessions. Over time, the stretch marks become less textured, the skin feels firmer, and tone evens out naturally.

FREQUENTLY ASKED QUESTIONS
Q: How often can I microneedle stretch marks?
A: For the body, once every 3–4 weeks is ideal. Allow the skin to fully recover before repeating.
Q: What depth should I use for body microneedling?
A: 1.0mm is generally effective for stretch marks; thicker scars may require up to 1.5mm. Never exceed 2.0mm at home.
Q: Can I use PDRN with other serums?
A: Yes—after the main PDRN application, you can layer mild hydrating or antioxidant serums like HA or vitamin C. Avoid actives such as retinol or acids for 3–5 days.
Q: Is PDRN approved in the U.S.?
A: Not yet. PDRN is widely used in Korea and other regions, but it’s not FDA-approved for cosmetic use in the U.S. It’s used here only as a topical or educational demonstration.
Q: When will I see results?
A: Most people notice smoother texture and firmer skin after 3–5 sessions spaced 4 weeks apart.
FINAL THOUGHTS
Stretch marks don’t disappear overnight, but with consistent microneedling and regenerative serums like PDRN, you can visibly tighten and smooth your skin texture over time.
