Stretch marks, or striae, form when the skin stretches beyond its natural capacity, causing collagen and elastin fibers to break. This results in thin, scar-like streaks that initially appear red, purple, or dark brown before fading to a lighter shade over time. Superficial to medium chemical peels help improve the appearance of stretch marks by exfoliating damaged skin layers, boosting collagen regeneration, and promoting skin renewal. These peels work by stimulating new skin cell growth, leading to a smoother texture and a more even skin tone.

Chemical peels for stretch marks work by inducing controlled exfoliation and collagen remodelling in the dermal layer where striae form. Stretch marks are essentially scars caused by rapid stretching of the dermis — the collagen and elastin fibres rupture, leaving behind atrophic bands of tissue.

This treatment targets stretch marks by:

Exfoliation & Skin Renewal – Exfoliating dead and damaged skin cells, promoting fresh skin renewal.

Collagen & Elastin Stimulation – Boosting collagen and elastin production, improving skin elasticity.

Stretch Mark Fading – Reducing the depth and color of stretch marks, making them less noticeable.

Smoother Skin Texture – Enhancing skin texture, leading to a smoother and firmer feel.

Gradual Skin Regeneration – Encouraging gradual skin regeneration, lightening older stretch marks over time.

Glycolic Acid 50-70% – High-concentration glycolic acid promotes rapid epidermal turnover and stimulates fibroblast proliferation in the upper dermis.

TCA 20-35% for Body Skin – Trichloroacetic acid at moderate concentrations reaches the papillary dermis on body sites, triggering collagen remodelling within the stretch mark.

Combination Glycolic-TCA Protocol – Alternating glycolic and TCA peels across a treatment series allows cumulative improvement without overloading the skin's healing capacity.

Acid selection for stretch mark peels differs from facial peel protocols because body skin is thicker and heals differently. The trunk, thighs, and upper arms have fewer pilosebaceous units — the hair follicle structures that serve as re-epithelialisation reserves during healing.

Collagen Synthesis – Stimulating collagen synthesis to repair the skin’s structural damage.

Discoloration Reduction – Fading stretch mark discoloration, reducing red, purple, or white streaks.

Texture Refinement – Improving skin texture, smoothing rough, uneven areas.

Skin Firmness & Elasticity – Enhancing skin firmness, restoring elasticity for healthier-looking skin.

Striae Rubra Protocol – Newer, red stretch marks receive TCA at 25 to 35 percent to capitalise on the existing inflammatory activity and blood supply.

Striae Alba Approach – Mature white stretch marks require a longer treatment series with more conservative acid concentrations. We focus on gradually thickening the atrophied tissue and may combine peels with microneedling to create.

Post-Session Topicals – After each peel, we apply tretinoin cream directly to treated stretch marks to maintain collagen stimulation between sessions.

Treatment at Claire Derma follows a multi-session protocol tailored to your stretch mark severity and body location. Sessions are spaced three to four weeks apart, with a typical course involving four to six treatments. At each visit, our dermatologist assesses the response — measuring changes in striae width, depth, and colour against baseline photographs.

Stretch Mark Reduction – Gradually fades both new and old stretch marks.

Collagen Regeneration – Stimulates collagen production, repairing and strengthening skin structure.

Skin Texture Enhancement – Smooths and softens the skin for a more refined appearance.

Even Skin Tone – Helps blend stretch marks with surrounding skin tone.

Non-Invasive & Safe – Minimally invasive with little to no downtime.

Benefit – Lower hyperpigmentation risk on darker skin compared to laser treatments. Chemical peels allow gradual depth control through layering, reducing the chance of post-inflammatory pigment changes that disproportionately affect higher Fitzpatrick.

Benefit – Minimal downtime for body-site treatment. Unlike ablative lasers that may restrict clothing and movement for days, chemical peels on stretch marks involve mild redness and peeling that most patients manage.

Benefit – Cumulative collagen improvement across serial sessions. Each peel builds on the previous one, progressively thickening the atrophic stretch mark tissue and improving both texture and colour.

Chemical peels offer practical advantages over other stretch mark treatments. Unlike fractional lasers, which carry higher hyperpigmentation risk on darker body skin tones, peels can be titrated carefully for Fitzpatrick types IV through VI.

This treatment is ideal for individuals who:

Have new or old stretch marks and want to reduce their appearance.

Seek gradual and natural-looking improvement.

Chemical peels improve the appearance of stretch marks but do not make them disappear. They reduce colour contrast, smooth textural depressions, and narrow the width of striae. Newer red or purple marks typically show 40 to 60 percent improvement after a full treatment series, while mature white marks may improve 20 to 35 percent.
