Glossary of Laser Treatment Terms
At Laser Forefront, we believe in empowering our readers with knowledge to make informed decisions about their laser treatment options. This glossary provides clear definitions of common terms you may encounter when researching laser-based beauty, skincare, vision correction, and wellness treatments.
A
Ablative Laser
A type of laser treatment that removes the outer layers of the skin to treat wrinkles, scars, and pigmentation, promoting collagen production and skin renewal. Examples include CO2 and Erbium lasers.
Active Cooling
A cooling mechanism used in laser devices to protect the skin from excessive heat and minimize discomfort during treatment.
Aftercare
The post-treatment regimen that patients must follow to ensure proper healing and optimal results, which may include avoiding sun exposure and using prescribed skincare products.
B
Broadband Light (BBL)
A type of intense pulsed light (IPL) therapy that targets pigmentation, sun damage, and signs of aging by delivering light energy to the skin’s deeper layers.
Burning Sensation
A mild to moderate sensation of heat that patients may experience during or after laser treatments. This is typically temporary and subsides with proper aftercare.
C
Collagen Stimulation
A process triggered by laser treatments that enhances the production of collagen, a protein essential for maintaining skin elasticity and firmness.
Cooling Gel
A gel applied to the skin before laser treatment to reduce heat sensation and protect the skin from thermal damage.
Cumulative Results
The gradual improvement in skin texture, tone, or hair reduction achieved through multiple laser treatment sessions.
D
Downtime
The recovery period required after a laser procedure during which patients may experience redness, swelling, or peeling. Downtime varies based on the treatment type.
Dermal Layer
The inner layer of the skin targeted by many laser treatments to promote healing and rejuvenation.
E
Erbium Laser
A type of ablative laser used for skin resurfacing that offers a gentler alternative to CO2 lasers, suitable for fine lines, wrinkles, and pigmentation concerns.
Epidermis
The outermost layer of the skin that laser treatments can target for surface-level issues such as pigmentation and mild wrinkles.
F
Fractional Laser
A laser treatment that delivers energy in a fractionated pattern, treating microscopic zones of skin while leaving surrounding tissue intact, allowing for faster healing.
Fluence
The amount of laser energy delivered per unit area, which is a key factor in the effectiveness and safety of laser treatments.
H
Hair Follicle
The part of the skin where hair growth begins, targeted during laser hair removal to reduce or stop hair regrowth.
Hyperpigmentation
A condition where patches of skin become darker than the surrounding area due to increased melanin production, which can sometimes occur after laser treatments.
I
Intense Pulsed Light (IPL)
A non-laser light therapy that targets pigmentation, vascular lesions, and signs of aging by using broad-spectrum light energy.
Invasive vs. Non-Invasive Treatments
- Invasive treatments involve penetrating the skin, often requiring downtime.
- Non-invasive treatments work on the surface and typically have little to no recovery time.
L
Laser Resurfacing
A skin treatment that removes damaged skin layers to reduce wrinkles, scars, and hyperpigmentation, promoting new skin growth.
Low-Level Laser Therapy (LLLT)
A non-invasive laser treatment that stimulates cell regeneration and reduces inflammation, commonly used for hair restoration and pain relief.
M
Melanin
The pigment in the skin and hair that absorbs laser energy during treatments such as laser hair removal and pigmentation correction.
Microneedling with RF (Radiofrequency)
A treatment that combines microneedling with RF energy to enhance collagen production and skin tightening.
P
Photorejuvenation
A skin treatment using laser or IPL to address issues such as sun damage, redness, and uneven skin tone.
Pulse Duration
The length of time a laser emits energy during treatment, impacting how deep the energy penetrates the skin.
R
Radiofrequency (RF) Therapy
A non-invasive skin treatment that uses RF energy to heat the skin and stimulate collagen production for tighter, smoother skin.
Redness and Swelling
Common temporary side effects of laser treatments that typically subside within a few hours to days.
S
Skin Tightening
A laser treatment aimed at improving skin laxity by stimulating collagen and elastin production for firmer, youthful-looking skin.
Spot Size
The diameter of the laser beam, which affects the precision and coverage area of the treatment.
T
Tattoo Removal
A laser treatment that breaks down tattoo ink particles, allowing the body to naturally eliminate them over time. Multiple sessions are often required for complete removal.
Topical Anesthetic
A numbing cream applied before laser treatment to minimize discomfort during the procedure.
U
Ultrapulse Technology
An advanced laser feature that delivers ultra-short pulses of energy for enhanced precision and minimal skin damage.
UV Protection
Sunscreen and protective measures recommended after laser treatments to prevent sun damage and pigmentation changes.
V
Vascular Lesions
Blood vessel abnormalities treated with laser therapy, including conditions such as spider veins and rosacea.
Visible Light Spectrum
The range of light wavelengths used in laser treatments to target various skin concerns.
Y
YAG Laser (Nd:YAG)
A versatile laser type used for hair removal, skin rejuvenation, and vascular treatments, suitable for a wide range of skin types.
Z
Zero Downtime Procedures
Laser treatments that require little to no recovery time, allowing patients to resume daily activities immediately.
