PDRN (Salmon Sperm)
Skin Repair, Regeneration, and Rejuvenation
PDRN is a regenerative treatment used to support skin healing, improve texture, and enhance overall skin quality.
At Radiant You, we use PDRN in combination with microneedling to deliver deeper, more meaningful skin rejuvenation.
Quick Take
- Supports collagen production and skin repair by providing the body with building blocks to use to grow new, healthy skin
- Improves texture, tone, and elasticity
- Reduces inflammation and supports healing
- Works best when combined with microneedling
- Typically performed in a series of treatments
What Is PDRN?
PDRN (polydeoxyribonucleotide) is derived from highly purified DNA fragments and works by supporting your skin’s natural repair processes.
It helps:
- Stimulate collagen (what gives skin strength/texture) production
- Improve skin elasticity and texture
- Reduce inflammation
- Support cellular repair and regeneration
How PDRN Works
PDRN interacts with your body’s natural healing pathways to:
- Activate fibroblasts (collagen-producing cells)
- Promote tissue repair
- Reduce oxidative stress and inflammation
- Support long-term skin quality
Rather than forcing change, it helps your skin function more effectively.
Why We Combine PDRN with Microneedling
Microneedling creates controlled microchannels in the skin, allowing PDRN to penetrate more deeply.
This combination:
- Enhances absorption of PDRN
- Amplifies collagen stimulation
- Speeds post-treatment recovery
- Improves overall results
What to Expect
After treatment:
- Mild redness for 24–48 hours
- Temporary dryness or sensitivity
Results develop gradually:
- 1–2 weeks: Improved texture and glow
- 4–12 weeks: Continued collagen remodeling
- Best results: With a series of treatments
Treatment Planning
PDRN works by stimulating your body’s natural repair processes, which build over time.
Most patients benefit from:
- A series of 3–5 treatments
- Ongoing maintenance treatments as needed
- Consistent at-home skincare support
Safety
PDRN has a strong safety profile and is generally well tolerated.
The purification process removes proteins that could trigger allergic reactions.
How This Fits Into Your Skin Health
PDRN is designed to support your skin’s ability to repair and regenerate.
It works best when combined with:
- Sun protection
- Consistent skincare
- Healthy lifestyle habits
And if you’re looking to improve your overall skin health more broadly, we can help guide a more comprehensive approach at Radiant You.
