laserhoito

Laserhoito is the Finnish term for laser treatment, a broad category of medical and cosmetic procedures that use focused light energy to interact with tissue. The laser emits light at a specific wavelength and pulse duration, which determines its effect on tissue and its ability to target certain chromophores such as water, melanin, or hemoglobin. By selecting appropriate parameters, clinicians can cut, ablate, coagulate, or stimulate remodeling with precision larger than conventional methods.

Applications include dermatology (removal of pigmented lesions, tattoo removal, treatment of vascular lesions, scar revision, wrinkle reduction, and hair removal), ophthalmology (refractive surgery; lasers such as excimer and femtosecond types), dentistry (soft tissue and hard tissue procedures), and gynecology or otolaryngology for certain interventions.

Common laser types include CO2 and Er:YAG lasers for ablation of superficial and deep layers; Nd:YAG, diode, and Alexandrite lasers for deeper penetration or hair removal; and pulsed dye or KTP lasers for vascular targets. Fractional and non-ablative variants are used to minimize downtime.

Procedures are performed by trained clinicians in appropriate settings, with pre-procedure assessment, informed consent, and eye protection. Local anesthesia or topical anesthetics may be used, and cooling or topical anesthetics help reduce discomfort. Post-treatment care typically includes sun protection, skincare, and avoidance of friction or infection risk.

Risks include pain, redness, swelling, transient pigment changes, blistering, scarring, and infection. Suitability depends on skin type, medical history, and medications. While many laserhoito procedures offer substantial improvements, results vary and multiple sessions are often required.
