What should you know about fractional co2 laser for stretch marks?

Stretch marks form when the skin changes faster than its supporting structures can adapt. Fractional laser energy reaches selected columns within the affected skin, prompting a repair response. It may make lines less noticeable or improve their surface feel, but mature pale marks and newer reddish or purple marks can respond differently. The treated skin does not become identical to untouched skin.

Temporary redness, swelling, warmth, tenderness, peeling, or tiny crusts are possible. Body areas may rub against clothing, so the clinician should discuss friction, sweating, active inflammation, pigment history, pregnancy or breastfeeding, and the chance of delayed colour change before treatment.

Tell the practitioner where the marks are, how long they have been present, whether they are changing, and which creams or procedures you have tried. Mention recent tanning, medicines, allergies, cold sores, and any history of raised scars or dark marks after injury. Do not wax or irritate the area unless the clinic permits it.

After treatment, wash gently, apply the recommended bland moisturiser, choose loose clothing when possible, and keep the area protected from sun. Do not scratch or remove crusts. Follow the review schedule; treatment intensity and spacing should be adjusted to the area's response rather than copied from someone else's plan.

Contact the clinic if pain or swelling is increasing, redness spreads, the area becomes hot and increasingly tender, or there is pus, fever, blisters, or a bad smell. Seek urgent help for a severe allergic reaction or breathing difficulty. Persistent darkening, lightening, open skin, or a raised scar warrants assessment before another session.

Ask whether the marks are mature or recent, what change the clinician expects, how body location affects settings and healing, and whether fractional laser or another approach is more appropriate. Discuss numbing, clothing and showering, work and exercise, sun exposure, follow-up photographs, and what would make the team postpone the next session.
