Type of laser according to skin type
Identifying the skin's actual needs before choosing laser treatment
Before deciding on the appropriate laser treatment, it is essential to define the therapeutic goal precisely. The indication is based on a clinical assessment of the skin and identification of the underlying pathophysiological mechanism.
Dull skin does not require the same approach as skin laxity, pronounced wrinkles or pigmented lesions. Each situation requires a specific strategy.
Some common indications guide the choice of device : skin ageing with reduced firmness; fine lines; sun-induced hyperpigmentation; diffuse redness and couperose; acne scars; enlarged pores and uneven texture.
Each of these indications corresponds to a distinct biological mechanism : collagen deterioration, excess melanin, vascular dilation or disruption of the dermal structure.
The selected laser must specifically target the structure concerned (tissue water, melanin or haemoglobin) and act at the appropriate depth. The suitability of the treatment therefore depends directly on the accuracy of the medical diagnosis.
What results can laser treatment achieve ?
In aesthetic medicine, the choice of laser is based exclusively on the clinical indication and the therapeutic goal defined during the consultation. Each technology has a specific tissue target and a defined depth of action. Treatment is therefore selected individually to achieve a result suited to the quality and characteristics of the skin.
Laser treatment can improve various skin changes, including :
• Improving skin quality and evening out the skin's surface.
• Reducing fine lines and superficial wrinkles.
• Partially reducing the depth of certain established wrinkles.
• Correcting sun-induced hyperpigmentation and evening out the complexion.
• Improving the appearance of scars, particularly acne scars.
• Reducing diffuse redness and treating certain superficial vascular lesions, such as couperose or fine telangiectasia.
• Reducing stretch marks by stimulating skin remodelling.
• Firming the skin by inducing collagen synthesis.
In general, laser treatment induces gradual dermal remodelling. The skin becomes denser, more even and brighter. The effect relies on physiological tissue repair and regeneration mechanisms.
The complexion appears more even, skin texture becomes more refined and the face looks clearer overall. Improvement is gradual and depends on the initial indication and the treatment protocol used.
The aim of laser treatment performed in a rigorous medical setting is not to alter facial features, but to restore skin quality in a measured, consistent and natural way.
Which laser treatment should you choose for ageing skin ?
When the main concern is skin ageing, laser treatment aims to stimulate collagen synthesis.
Photorejuvenation lasers are suitable for skin with a mild to moderate loss of firmness. They induce controlled thermal stimulation of the dermis without damaging the epidermis. Recovery is quick and results develop gradually.
Ablative fractional lasers, particularly CO2, are indicated when wrinkles are more pronounced or photoageing is advanced. They cause controlled ablation of the epidermis and more intensive dermal remodelling. Recovery takes longer, but effectiveness is greater.
The choice therefore depends on the degree of ageing, skin thickness and tolerance for post-treatment recovery.
Which laser treatment should you choose for pigmentation spots ?
Sun spots and lentigines require a laser that targets melanin. Pigment lasers work on the principle of selective photothermolysis. Light energy is absorbed by the pigment, causing it to fragment.
Treatment is generally quick. The spots temporarily darken before gradually disappearing.
Skin phototype plays a decisive role in the choice of laser. On darker skin, certain devices must be used cautiously to limit the risk of post-inflammatory hyperpigmentation.
Which laser treatment should you choose for redness and blood vessels ?
When the skin has diffuse redness or superficial vascular lesions, a vascular laser is indicated. It targets the haemoglobin in dilated blood vessels.
This treatment reduces the intensity of redness and improves the evenness of the complexion. Several sessions may be necessary depending on the extent of the lesions.
The choice of settings depends on the depth and diameter of the vessels.
Which laser treatment should you choose for acne scars ?
The choice of treatment depends above all on the type and depth of the scars. Not all acne scars require the same approach.
In most cases, a fractional laser is used. This technology creates microscopic columns of ablation within the dermis. This triggers a skin repair process and stimulates collagen production. The skin gradually restructures and the depressions diminish.
Improvement is gradual. Several sessions are necessary, spaced a few months apart. Fractional laser treatment reduces skin irregularities but does not completely erase deep scars.
When scars are more pronounced, particularly with a very uneven surface, a continuous ablative laser may be indicated. This treatment performs a medium-depth laser peel, meaning controlled, uniform abrasion of the skin's surface. It allows greater scar correction, at the cost of longer social downtime and a more substantial healing phase.
The initial clinical assessment is crucial. It involves analysing the depth and extent of the scars and the patient's skin phototype. The choice of laser must be adapted to these factors to achieve the best possible result under optimal safety conditions.
The role of skin phototype in choosing laser treatment
Skin phototype, meaning the skin's natural response to sunlight and its pigmentation, strongly influences the choice of laser treatment.
Lighter phototypes have a lower risk of post-treatment pigmentation disorders. Intermediate and darker phototypes require more cautious settings.
Tanned skin should not be treated, as the risk of pigmentation complications is very high.
Assessment of skin phototype is an integral part of the treatment decision.
Should several treatments be combined ?
In some cases, a single type of laser is not enough to address all skin concerns. Skin may have pigmentation spots, wrinkles and a loss of firmness at the same time.
A combined strategy may then be considered. The choice relies on setting priorities and appropriate planning.
Conclusion : which laser treatment should I choose for my skin ?
Choosing a laser treatment for the skin relies on a precise medical assessment. It depends on the indication, skin phototype, skin quality and the patient's expectations.
There is no universal laser. Each technology has specific indications. The most suitable treatment is the one that follows a thorough diagnosis and forms part of a consistent strategy.
The question “Which laser treatment should I choose for my skin ?” cannot receive a standard answer. It requires a personalised assessment, the only way to ensure a visible and safe result.
