At Between the Lines Aesthetics, we offer treatments grounded in science. Microneedling—also called percutaneous collagen induction therapy—is a safe, minimally invasive procedure proven to improve acne scars, wrinkles, photoaging, and overall skin rejuvenation. [1–2]

What Is Microneedling?

Microneedling uses fine needles to create tiny, controlled micro-injuries in the skin. [1][3] This triggers the body’s natural wound-healing response, boosting collagen and elastin production while normalizing cell function in keratinocytes and melanocytes. Unlike more aggressive procedures, it preserves the epidermis, reducing inflammation, downtime, and the risk of pigmentation issues. [3]

Clinically Proven Benefits

1. Collagen & Elastin BoostStudies show collagen and elastin can increase up to 400% after 6 months, with structural improvements lasting a year. [4–5]

2. Comprehensive RejuvenationMicroneedling improves multiple signs of aging at once:

Wrinkles & fine lines: Visible smoothing with histological improvement [5]
Texture & tone: Normalized melanocyte function [3]
Skin laxity: Increased structural protein production [6]
Photoaging: Reverses sun damage [1–2]

3. Versatile ApplicationsEffective for:

Acne scars, hypertrophic scars, keloids [1–2][7]
Stretch marks (striae) [6]
Hyperpigmentation and melasma [2]
Androgenetic alopecia [7]
Periorbital dark circles [8]Treatments can extend beyond the face to the neck and décolletage. [4]

4. High Patient SatisfactionA meta-analysis reported 83% satisfaction, thanks to visible results, minimal side effects, and short recovery. [9]

Safety & Minimal Downtime

Microneedling is well-tolerated with rare permanent effects. Common mild reactions include:

Redness (6.8%)
Scaling (1.7%)
Burning (1.5%)
Itching (0.4%) [9]

Transient hyperpigmentation can occur but usually resolves quickly. Safe for all skin types, including Fitzpatrick III and IV. [2][5][8]

Enhanced Results with Combinations

Microneedling can be paired with:

PRP (platelet-rich plasma) [6]
Radiofrequency energy [3]
Topical growth factors & actives [6]
LED therapy or chemical peels [6]

Microchannels created during treatment also enhance absorption of topical products. [1][3]

Treatment Timeline

Optimal results typically require 3–6 sessions spaced 2–4 weeks apart. [4–5] The skin continues producing collagen over time, with visible rejuvenation lasting months after the final treatment. [11]
