Laser treatments & protocols

I have built this index to provide an evidence-informed overview of laser and energy-based device protocols organised by skin concern. I have outlined the photothermal mechanism and the rationale for using specific wavelengths so that practitioners have a starting point for parameter assessment.

Consumers can use this to understand the intended outcome of a specific laser treatment and the extent of its limitations. This ensures the decision you make is based on the science rather than the marketing.

Acne, scarring & textural remodeling

To use focused thermal energy to remodel fibrotic scar tissue and address sebaceous activity in skin prone to congestion and post-inflammatory scarring.

Fractional lasers, both ablative and non-ablative, create microscopic treatment zones that penetrate the dermis to break down the fibrotic collagen characteristic of acne scarring, supporting gradual improvement in scar texture over a structured course of treatments. For active congestion, specific wavelengths such as 1450nm can target sebaceous glands to reduce oil production at the source. The thermal burden of these treatments requires careful management in reactive or darker skin types, and your practitioner can help you understand what is appropriate for your skin.

Hyperpigmentation & melanin regulation

To achieve targeted pigment reduction by delivering ultra-short energy pulses that break down melanin deposits without significantly affecting surrounding tissue.

Q-switched and picosecond laser technologies deliver energy in ultra-short bursts, producing a photo-acoustic effect that breaks down melanin into microscopic particles for gradual lymphatic clearance. This may offer targeted clearance for isolated lesions such as sun spots where the pigment is well-defined. For conditions such as melasma, where excess thermal energy can trigger rebound pigmentation, low-fluence protocols are used. Melasma always requires careful clinical management and expectations should be discussed with a practitioner who understands your specific pigmentation profile.

Dermal elasticity & structural aging

To support structural collagen renewal and address skin laxity through deep-reaching thermal energy or high-intensity focused ultrasound.

HIFU (High-Intensity Focused Ultrasound) and long-pulse Nd:YAG lasers target the deeper structural layers of the skin, including the SMAS, the connective tissue layer beneath the dermis. The thermal stimulus causes an immediate tightening effect followed by a 3 to 6 month neocollagenesis process, supporting improved firmness and skin rejuvenation over time. For those not yet considering injectables or surgical options, energy-based treatments offer a meaningful non-invasive alternative. Your practitioner can help you understand how these treatments integrate into a wider plan.

Vascular resilience & redness management

To reduce persistent redness and visible capillaries by targeting haemoglobin within blood vessels with wavelengths that are selectively absorbed by oxygenated blood.

Vascular lasers, including pulse dye lasers and KTP lasers, cause targeted blood vessels to collapse and be gradually reabsorbed by the body, reducing the visible redness associated with dilated capillaries and telangiectasia (visibly dilated small blood vessels near the skin surface). Rosacea is a complex, chronic condition and laser treatment addresses the vascular component rather than resolving the condition entirely. I always recommend starting this conversation with a practitioner who understands your full skin profile.

Body rejuvenation & follicular clearing

To address deeper structural concerns and follicular irregularities on thicker body skin using higher-power energy delivery calibrated for the demands of body tissue.

Body skin is significantly thicker than facial skin, requiring long-pulse lasers or large-spot fractional devices to reach the necessary depth. For follicular clearing including keratosis pilaris (KP), laser energy can target the base of the hair follicle to address the keratin plug at its source. For skin rejuvenation and deep tissue renewal on the chest or limbs, higher energy density is required to penetrate the thicker epidermal barrier. KP has a genetic component and cannot be fully resolved, but a consistent approach can make a real and visible difference. Your practitioner will advise on post-treatment hydration and realistic expectations.
