Laser Treatments on Indian Skin: What Fitzpatrick IV–VI Changes

Laser devices do not treat skin. They deliver energy that is absorbed by a target — melanin, haemoglobin, or water — and the clinical result depends entirely on how selectively that happens.

That is why skin tone matters so much. In Fitzpatrick types IV to VI, which covers most Indian skin, there is substantially more melanin sitting in the epidermis, competing for the same energy. Treat that skin with settings designed for Fitzpatrick I–II and the epidermis absorbs energy meant for the target, inflames, and responds the way it always responds to injury: by making more pigment.

Post-inflammatory hyperpigmentation is the main risk

PIH is the dark patch that appears weeks after a treatment, sometimes worse than the problem being treated. It is not an allergic reaction and not usually permanent, but it can take six to twelve months to fade and it is genuinely distressing.

It is also largely preventable. The variables that matter are wavelength selection, fluence, pulse duration, cooling, the interval between sessions, and what you are doing to the skin before and after.

What good practice looks like

• A documented Fitzpatrick assessment before the first treatment, not an estimate from a photo
• A test patch in a discreet area, reviewed two to four weeks later, before treating a whole face
• Longer wavelengths where possible — they penetrate past epidermal melanin more safely
• Lower fluences with more sessions, rather than aggressive single treatments
• Effective epidermal cooling throughout
• Longer intervals between sessions than the device manufacturer's default schedule

Melasma deserves its own paragraph

Melasma is common in Indian skin, hormonally driven, and it behaves badly under heat. Aggressive laser treatment can clear it briefly and then trigger a rebound that is worse than the starting point.

Current practice is low-fluence, high-frequency protocols combined with medical topicals and — the part patients most often skip — genuinely strict daily photoprotection. Melasma is managed rather than cured, and any clinic promising permanent clearance in a fixed number of sessions is overselling.

Sun protection is not an upsell

Bengaluru sits at 12° north. UV levels are high year-round, and visible light — which ordinary sunscreens do not block — also drives pigmentation in deeper skin tones.

That is why tinted sunscreens containing iron oxides are recommended after pigment treatments: the tint is what blocks visible light. Broad-spectrum SPF 50, reapplied, plus shade and timing. Without it, the treatment is being undone between sessions.

Which treatments need the most caution

Ablative resurfacing carries the highest PIH risk and needs the most conservative approach and the most thorough pre-conditioning of the skin.

Hair removal on deep skin needs long-wavelength devices; using the wrong wavelength on dark skin risks burns, not just pigment change.

Vascular treatments are generally safer but still need careful cooling.

Non-ablative and fractional approaches sit in the middle — usually well tolerated, but still not something to have done at maximum settings on a first visit.

Realistic expectations

Most pigment and texture concerns need three to six sessions spaced four to six weeks apart, and improvement is gradual. Results that appear after one session on social media are either a different starting point, a different problem, or a filter.

The honest version: deeper skin tones can be treated safely and effectively with lasers, but they need a clinician who adjusts protocol to skin type rather than following the device preset. Ask what settings are being used and why. A clinic that can answer that is a clinic that thought about it.
