What is a stretch mark?
A fine scar of the skin, appearing when the fibres of the dermis (collagen, elastin) tear under too rapid a stretch. It is first red or purplish, slightly raised and sometimes itchy, then becomes white, pearly and more depressed over time. It mainly affects the belly, breasts, hips, thighs, buttocks, arms and lower back.
Why do they appear?
Several factors add up: family predisposition, hormones (pregnancy, puberty), the speed of weight gain or loss, rapid growth, intense bodybuilding and prolonged use of corticosteroids (strong creams or tablets). Numerous, wide stretch marks or ones appearing with no obvious cause, especially in a teenager or young adult, warrant a consultation to look for a cause to treat.
Can they be prevented?
Gradual weight gain, good hydration and gentle massage help the skin adapt, but personal predisposition plays a major role: no cream reliably prevents them from appearing, and promises that sound too good should be treated with caution. During pregnancy, the skin is supported; corrective treatments are done after delivery.
Red or white stretch marks: not the same treatment
Recent stretch marks, red or purplish, are still rich in small vessels: they generally respond better and faster, with lasers targeting redness, treatments that stimulate the skin and, outside pregnancy and breastfeeding, retinoid products on prescription. Old stretch marks, white and pearly, are harder: we seek to improve relief and texture with treatments that stimulate collagen, over several sessions.
Treatments offered at the clinic
Depending on the examination: the fractional Er:YAG laser of the Fotona SP Dynamis Nx Line platform, to remodel texture and relief; the Nd:YAG, for stretch marks that are still red; Dermapen (microneedling), which stimulates the skin through micro-punctures; PRP as a complement; and, for certain laxity of the belly, arms or thighs, a firming protocol. Treatments are chosen and combined according to colour, age, area and skin type.
How many sessions, and what results?
Several sessions are generally needed, a few weeks apart, to improve colour, suppleness and relief gradually; the exact number is announced after the examination. Improvement is partial: a stretch mark does not fade completely, and the result varies with its age, the area and your skin. Comparison photos before and during sessions allow progress to be followed.
Olive and pigmented skin: particular vigilance
On olive or dark skin, any inflammatory treatment (laser, microneedling) can leave a brown mark if settings or preparation are not suitable. Dr Zahid is trained in dark skin types: individualised settings, skin preparation, choice of season, strict sun protection. Marrakech's sun means sessions are best planned in autumn and winter.
Stretch marks, pregnancy and after delivery
During pregnancy, the clinic performs neither laser nor Dermapen: we limit ourselves to supporting the skin (hydration, gradual weight gain). After delivery, and taking breastfeeding into account, a gradual programme is defined, stretch marks that are still red generally responding better. The markers are detailed on the dermatology and pregnancy page.
Aftercare, precautions and contraindications
After a session, the skin is red and tender for a few days, sometimes with slight peeling. Avoid sun and tanning before and after, moisturise and apply sun protection. Treatments are postponed in case of pregnancy, tanned or damaged skin, recent isotretinoin treatment or a tendency to keloid scars, which is assessed at the consultation.
