Laser and device treatments use controlled energy, such as light or radiofrequency heat, to target one specific thing in the skin: hair pigment, blood vessels, water in skin cells, or the collagen in deeper layers. At Swãe Medspa in Hermosa Beach, the Lasers and Devices category includes laser hair removal, skin resurfacing, XERF Skin Tightening, XERF Body Contouring and vein removal. The right choice depends less on which device sounds most advanced and more on what you're trying to change.
This guide breaks down what each option is designed for, how much downtime to expect, and the questions worth asking before your first session.
How Do Laser and Energy-Based Treatments Work?
Every energy-based treatment works by delivering heat to a chosen target while trying to spare the surrounding skin. The type of energy decides the target. Swãe's category page explains it this way: lasers target specific things like pigment, blood vessels or water in skin cells, while radiofrequency heats deeper layers to stimulate collagen over several months.
That's why one device rarely does everything well. A laser tuned to find dark hair follicles isn't the same tool you'd choose to smooth acne scars, and neither one tightens loose skin along the jawline.
Most of these treatments also share a few traits: they usually work best as a series, results build over weeks to months, and sun protection before and after is part of the plan.
Which Laser or Device Treatment Is Right for My Concern?
Choosing the right laser or device treatment starts with identifying your primary skin or body concern. At Swãe Medspa in Hermosa Beach, California, different technologies are available to address specific aesthetic goals.
- Unwanted Hair: Laser Hair Removal uses laser energy absorbed by hair pigment to target hair follicles and reduce unwanted hair growth. Swãe's Clarity II technology is among the devices used for this purpose.
- Sun Damage, Brown Spots, Uneven Texture, and Fine Lines: Skin Resurfacing uses laser technology to improve skin texture, pigmentation, and certain visible signs of aging. The appropriate approach depends on the concern, skin type, and treatment goals.
- Mild to Moderate Skin Laxity: XERF Skin Tightening uses radiofrequency energy to heat deeper layers of tissue and stimulate collagen remodeling. It may help improve firmness around the face, jawline, neck, and eye area.
- Loose Skin on the Abdomen, Arms, or Thighs: XERF Body Contouring uses radiofrequency technology to address skin laxity and improve the appearance of skin firmness and texture in selected body areas.
- Spider Veins and Visible Facial Vessels: Vein Removal may involve laser treatment or sclerotherapy, depending on the location, size, and type of visible veins.
Swãe also features technologies such as Clarity II, Lutronic Ultra, XERF, and SkinPen on its Devices page. Because each technology serves different purposes, a professional consultation helps determine which treatment is appropriate for your skin concerns, medical history, and desired results.
What Is Laser Hair Removal Best For?
Laser hair removal is best for reducing coarse, pigmented hair over a series of sessions. The laser's light is absorbed by pigment in the follicle, which heats the follicle and slows hair production. Swãe's page lists the face (including upper lip), underarms, bikini line, legs, arms, chest and back as treatment areas.
It is a long-term reduction treatment, not a guaranteed permanent one. The American Academy of Dermatology notes that most patients remain hair free for months or even years, that regrowth tends to be finer and lighter, and that some people need maintenance sessions. Swãe typically plans six to eight sessions spaced four to eight weeks apart, timed to catch hairs in their active growth phase.
Hair color matters. Swãe notes that blonde, red, grey or white hair has little pigment for the laser to target, so results are weaker.
Men: What About the Back, Chest or Beard Line?
For men who are tired of shaving or waxing, Swãe's listed treatment areas include the chest, back and face. Large areas like the back can take up to an hour per session, so ask about timing when you book. Facial and other hormonally driven areas may need more sessions than the typical series. If you want to keep a beard, talk through exactly where the line should sit before treatment starts, since the goal is long-term reduction.
What Does Skin Resurfacing Treat, and How Much Downtime Is There?
Skin resurfacing is Swãe's option for sun damage, brown spots, uneven tone, fine and moderate wrinkles, acne scarring and rough texture. It is a fractional laser treatment: the laser treats a pattern of tiny columns in the skin, leaving the skin between them intact so it heals faster than if the whole surface were treated.
Downtime depends on depth. Swãe describes light treatments as about two to three days of redness and light flaking, and deeper treatments as five to seven days of redness, swelling and peeling, with pinkness that can linger for a few weeks. Light resurfacing often takes a series of three to five sessions.
Swãe's Lutronic Ultra device page describes a gentle 1927 nm thulium fractional laser for sun spots, texture and fine lines, and notes that many patients treat on a Friday and feel back to normal by Monday. Your provider will tell you which device and depth fit your skin.
Busy Professionals: How Do I Plan Around Work?
If you can't take a week off, ask about lighter settings delivered as a series rather than one deep treatment. Swãe asks patients to plan three to seven days away from sun and social commitments for resurfacing, depending on depth, and to avoid direct sun for at least four weeks afterward. Hair removal and skin tightening typically have little to no downtime, which makes them easier to fit into a regular workweek.
How Does XERF Skin Tightening Differ From Body Contouring?
XERF Skin Tightening and XERF Body Contouring both use heat to prompt collagen remodeling, and both focus on skin firmness. XERF Skin Tightening is aimed at mild to moderate laxity on the face, jawline, neck and eyes, as well as some body areas. Results build gradually, with improvement continuing for up to six months.
XERF Body Contouring, as described on its service page, focuses on improving skin laxity and texture on areas like the abdomen, upper arms and thighs. Swãe's page states it is not a weight-loss treatment or a substitute for surgical skin removal. If your main goal is reducing fat, bring that up at your exam so your provider can tell you honestly what XERF can and can't do for you.
Neither treatment replicates a facelift. Swãe notes that significant sagging or excess skin may call for a surgical consultation instead.
Luxury and Long-Term Clients: Can Devices Be Combined?
For clients who want a comprehensive, maintained result rather than a one-off fix, some plans combine technologies. For example, a plan might pair resurfacing for sun damage with XERF for firmness, with treatments spaced so the skin can recover between them. Swãe's providers plan the order and spacing, and the practice states it doesn't use a one-size-fits-all approach. Periodic maintenance is part of most long-term plans; Swãe suggests skin tightening results typically last one to three years.
Are Laser Treatments Safe for Darker Skin Tones?
They can be, but device and settings matter a great deal. Some lasers are strongly absorbed by melanin, which can heat the skin itself in deeper skin tones and raise the risk of burns or pigment changes. Swãe's Clarity II page explains that its Nd:YAG wavelength is absorbed less by melanin and reaches deeper, which is why this type of wavelength can be suitable for hair and vein treatment in darker skin. Even then, burn and pigment risks still call for careful settings.
Resurfacing carries a higher risk of pigmentation changes on darker skin tones, according to Swãe's own resurfacing page, and your provider may adjust settings or recommend microneedling instead. The American Academy of Dermatology also notes that laser hair removal requires extra care for people with darker skin and that some skin color changes can be permanent. A careful provider will review your skin type, tanning history and medications first and may perform a test patch.
What Should I Do Before and After a Laser Treatment?
Sun protection is the biggest factor you control. Swãe asks patients to avoid sun exposure for a couple of weeks before and after laser treatments, and to avoid tanning beds and self-tanner before and after laser hair removal. MedlinePlus notes that UV rays can damage skin in any season and at any temperature, so this applies year-round, not only in summer. That can take planning in a beach town, so if you have a trip or tournament on the calendar, schedule around it.
For laser hair removal specifically, common steps include shaving the area about 24 hours before, telling your provider about medications that increase light sensitivity, and avoiding saunas, hot showers and intense workouts for a day or two afterward. Resurfacing has longer, more detailed aftercare, including at least four weeks of strict sun avoidance, which your provider will walk you through.
Frequently Asked Questions About Lasers and Devices
Do laser treatments hurt?
Most people describe warmth or a quick snap, and many devices have built-in cooling. Swãe uses numbing cream for more intense treatments such as resurfacing.
How many sessions will I need?
It depends on the treatment. Swãe typically plans six to eight sessions for laser hair removal. Light resurfacing often takes three to five sessions, while a deeper resurfacing treatment may need only one or two. XERF Skin Tightening is usually three to six sessions, though some higher-energy treatments need only one or two.
Is laser hair removal permanent?
It's best described as long-term reduction. Many people stay hair free for months or years, and occasional touch-ups may be needed.
Does XERF Body Contouring remove fat?
Swãe's XERF Body Contouring page describes it as a skin-tightening treatment focused on laxity and texture, not a weight-loss or fat-removal treatment.
Can I get laser treatments in summer?
You can, but you'll need to avoid sun exposure and tanning around each session, which is harder during beach season. Your provider may suggest timing certain treatments for cooler months.
Do I need a consultation first?
Yes. Every new Swãe patient has an in-person Good Faith Exam with a physician assistant before any service.
