Who may suit RedTouch Pro? A checklist before choosing a 675 nm laser

Suitability requires an examination, not age or photographs alone. This guide explains the information a physician needs and when another or combined approach may be more appropriate.

Quick answer

Who may be considered for RedTouch Pro?

RedTouch Pro may be considered for selected texture concerns, shallow acne scars, pores or fine lines after an in-person assessment. Age or photographs alone cannot establish suitability. Deeper or tethered scars, active inflammation, pigment history and current medicines may point to another or combined approach. Evidence is still limited, and individual results vary.

May suit
Selected texture or shallow-scar concerns after the scar structure and medical history are assessed.
Results
Change is gradual and variable; comparable photographs support a fair review, with no guaranteed outcome.
Risks
Redness, warmth, swelling, sensitivity or pigment change can occur; skin condition and settings matter.
Downtime
It may be limited for some people, but should not be assumed to be zero.
When to see a doctor
Before choosing treatment, and promptly for worsening pain, swelling, redness, blistering, wounds or colour change.

Who a physician may consider

  • People with selected texture concerns or shallow acne scars seeking a non-ablative approach.
  • People who understand that collagen remodelling is gradual and should be followed with standardised photographs.
  • People who can follow sun-protection, skincare and review instructions.

Studies of 675 nm lasers include skin-rejuvenation and acne-scar findings from limited samples. They can inform a discussion but cannot predict one person's outcome.

Define the acne-scar structure first

Acne scars include rolling, boxcar and ice-pick patterns, and some are tethered below the surface. If tethering or deeper scars are present, a laser alone may not be the most appropriate starting point. A physician may assess subcision or a structure-based combination plan.

What to tell the physician

  • Pregnancy, medical conditions, open wounds, infection or active acne in the treatment area.
  • Medicines or products that increase light sensitivity, including current acne and exfoliating products.
  • A history of unusual scarring, herpes, or dark or light marks after inflammation.
  • Recent tanning, sunburn, laser treatment or another procedure.
  • Your expected outcome and the period in which you hope to see change.

When treatment may need to be postponed

Sunburn, open wounds, infection or uncontrolled inflammation require assessment before proceeding. Treatment date and energy should not follow one formula for everyone. Do not stop prescribed medicines because of an online article; follow the prescribing clinician's advice.

A fair way to assess change

Use photographs with comparable lighting, angle, distance and skin condition. Record symptoms and adverse effects, and review at the interval set by the physician. Changing methods too often makes it difficult to identify benefit or irritation.
