Skin and Body Concerns: Find the Right Med Spa Treatment for Your Problem

A med spa works on appearance concerns, meaning how skin, hair and body contours look.

The tools fall into a few groups: injectable drugs (neuromodulators such as Botox), injectable fillers, lasers and intense pulsed light (IPL), chemical peels, microneedling, energy-based skin tightening and fat reduction, and laser hair removal.

The concern decides which tool fits, and this page walks through both.

The concerns a med spa can work on:

• Face: wrinkles, lost volume, sun damage and dark spots, acne scars and texture, redness and visible blood vessels.
• Body: stubborn fat bulges, cellulite, loose or sagging skin, unwanted hair, spider and varicose veins.
• Look-alikes: some complaints that seem cosmetic, like hair loss or a changing mole, are medical, and the section below on dermatologists explains why they come first.

Some concern guides are organized by person or occasion rather than by problem — med spa treatments for men, a pre-wedding skin treatment timeline and treatments during pregnancy and breastfeeding — and stretch marks have a guide of their own.

Two words carry legal weight on any menu of treatments.

Drugs and fillers are FDA-approved for the specific indications named on their labels.

Devices such as CoolSculpting, Ultherapy, Sofwave, Thermage, Morpheus8, Emsculpt and the lasers are FDA-cleared through the 510(k) process, not FDA-approved, and each clearance names the specific uses it covers.

Any use of a drug or filler outside its approved indication is off-label: it is not on that product's current US label, and the FDA says it may not have reviewed use elsewhere.

Each treatment below is tagged with its status so you know what to ask a provider about.

Injectables lead ASPS's procedure counts: in the American Society of Plastic Surgeons' 2025 report, neuromodulator injections, commonly called Botox, accounted for roughly half of all minimally invasive procedures performed by ASPS members, and hyaluronic acid fillers accounted for another 30 percent.

Those are plastic-surgeon survey figures rather than med spa counts.

Each face concern has its own toolset.

Wrinkles. Lines come in two kinds: dynamic lines that appear when muscles contract, and static lines visible at rest.

Botulinum toxin works best on the dynamic kind, and a 2014 review in American Family Physician reports full effect takes about two weeks and lasts three to four months. Botox Cosmetic is FDA-approved for temporary improvement of moderate to severe frown lines, crow's feet, forehead lines and, since October 2024, platysma bands (the vertical neck bands) in adults.

Other toxin uses you will see advertised, like the lip flip or masseter Botox jaw slimming, are not on any current US toxin label; masseter slimming in particular is off-label for every US toxin.

Volume loss. This is filler territory.

FDA approves dermal fillers for adults 22 and older, and each product is approved for particular areas: Juvéderm Voluma XC, for example, for the cheeks, chin and temples, and Juvéderm Volbella XC for under-eye hollows.

Use in other areas may not have been reviewed.

How long filler lasts depends on the material: AAD's table gives hyaluronic acid 4 to 12 months, calcium hydroxylapatite 6 months to 1 year and poly-L-lactic acid 1 to 3 years, while FDA's own page gives hyaluronic acid about 6 to 12 months and calcium hydroxylapatite about 18 months.

The two sources disagree, so treat duration as a range that depends on the product and the area.

The lips are their own topic; see lip filler.

Sun damage and dark spots. AAD lists chemical peels among the treatments for sun-damaged skin, age spots, freckles, melasma, uneven tone, fine lines and some acne, and notes insurance does not cover them.

FDA advises having a peel only under the supervision of a licensed, trained provider, because some at-home peels have caused serious injuries. Melasma is its own case: it cannot be cured, treatments fade it, and it commonly returns after unprotected sun exposure.

AAD lists peels, microneedling, laser and light treatments and PRP as add-ons when topicals and sun protection are not enough, and says only a board-certified dermatologist should perform them.

One warning belongs in the pigment section: what looks like an age spot could be skin cancer, and AAD recommends a dermatologist exam before treating any spot you plan to fade.

The dermatologist section below lists the concerns AAD routes to a doctor first.

Acne scars and texture. AAD names chemical peels, fillers, laser resurfacing, topical retinoids or salicylic acid for mild scarring, microneedling, PRP as an add-on, radiofrequency and RF microneedling, scar surgery and dermabrasion among the treatments for depressed acne scars, and notes microdermabrasion does not treat acne scars itself.

Plans depend on scar type, because ice pick scars need different treatment than rolling scars, and they often combine more than one approach.

In studies AAD cites, microneedling with PRP, done as 3 to 5 treatments every 2 to 4 weeks, faded acne scars by 50% to 70%: a study range, not a promise for any one person.

One filler is FDA-approved for acne scars: Bellafill, approved in December 2014 for moderate to severe atrophic (depressed), distensible facial acne scars on the cheek in patients over 21, and it is permanent (non-absorbable).

The links for this cluster are microneedling, chemical peel and CO2 laser resurfacing.

Redness and visible vessels. Rosacea is a chronic condition; AAD describes lasting facial color, acne-like breakouts and visible blood vessels, and is clear that it has no cure.

Lasers and other light treatments can reduce the visible vessels: in AAD's summary, most rosacea patients see a 50% to 75% reduction after 1 to 3 treatments spaced 3 to 4 weeks apart, with results tending to last 3 to 5 years, because treated vessels do not return but new ones can form.

AAD warns laser, light and electrodesiccation treatments for vessels can cause burns, permanent color change or scars in inexperienced hands, and recommends a board-certified dermatologist for them.

Stubborn fat. Fat-reduction treatments target bulges, not weight, and AAD frames candidacy narrowly: a small bulge of fat that remains despite diet and exercise, at a weight in the normal range for your height.

It is not a weight-loss method, and results are subtle compared with liposuction.

CoolSculpting Elite is FDA-cleared, not approved, for cold-assisted fat breakdown of the upper arm, bra fat, back fat, banana roll, thigh, abdomen and flanks in people with a BMI of 30 or less, and of the under-chin and jaw areas with a BMI up to 46.2. Kybella, a prescription injection, is FDA-approved only for moderate to severe under-chin fullness in adults; the label says it is not approved for fat outside that region and such use is not recommended.

AAD's typical session counts: cryolipolysis usually 2 sessions, ultrasound 1 to 3, radiofrequency 4 to 10, and injections for chin fat usually 2 sessions spaced 6 to 8 weeks apart; the Kybella label itself allows up to 6 single treatments, at least 1 month apart.

Device results can start as early as 3 weeks, with full effect 3 to 6 months after the last treatment.

Rarely, AAD notes, fat freezing can cause long-term pain or increase the amount of fat in the treated area, a condition called paradoxical adipose hyperplasia.

One hard line from the FDA: injectable liquid silicone is not approved for any aesthetic filling use, and the agency recommends against fillers for breast, buttock or body contouring.

Cellulite. Cellulite is not simply fat to be removed.

AAD says most women, even very fit women, have it, and that treatments which remove fat often have no effect on it.

The options with the best research support, per AAD, are acoustic wave therapy, some laser treatments, subcision (Cellfina) and vacuum-assisted precise tissue release; AAD does not recommend cryolipolysis, mesotherapy or supplements for cellulite.

Results are mostly temporary: AAD describes radiofrequency improvement as small and short-lived, endermologie results fading within about a month of stopping, and some laser results lasting 6 months or more before dimpling returns.

Loose skin. This concern splits by degree.

AAD says a surgical lift, such as a facelift or eyelid surgery, gives the most dramatic results, while non-invasive tightening with ultrasound, radiofrequency or some lasers gives modest tightening and lifting, with little or no downtime in AAD's description.

Candidacy is narrow: the best candidates for non-surgical tightening have only a small amount of sagging, a stable healthy weight, no smoking and sun protection, and with a lot of sagging skin, tightening may not help.

It is not for anyone pregnant or with a skin infection.

Unwanted hair. FDA-cleared laser hair removal devices are cleared for "permanent hair reduction", which their clearances define as a long-term, stable reduction in the number of hairs regrowing, measured 6, 9 and 12 months after a treatment course.

That is reduction, not removal of every hair.

AAD says to expect a 10% to 25% reduction after the first treatment, with most patients needing 2 to 6 treatments usually every 4 to 6 weeks, and may need maintenance sessions after that; the details are in our laser hair removal guide.

Spider and varicose veins. These form when one-way valves in the veins weaken; risk rises with family history, long periods of sitting or standing, age and pregnancy.

Varicose veins can cause pain and carry a risk of blood clots or leg sores, which is why AAD calls a physical exam essential before treatment.

The most common treatment is sclerotherapy: per AAD, spider veins usually disappear in 3 to 6 weeks and varicose veins in 3 to 4 months, often after 2 or 3 treatments, with compression stockings worn for 2 to 3 weeks.

Start with age, because the labels set floors.

FDA approves dermal fillers only for adults over 21 (22 and older, in the agency's wording), and botulinum toxin cosmetic labels are for adults, with pediatric safety not established.

Those two categories, fillers and botulinum toxin, have no approved cosmetic use below those ages.

Skin type is described on the Fitzpatrick scale, developed by Thomas Fitzpatrick in 1975, which classifies skin by its reaction to sun: type I always burns and never tans, through type VI, which never burns.

Cautions travel with the scale: it was created to dose UVA phototherapy for people with white skin, dermatologists have criticized its "never burns" descriptions for types V and VI as inaccurate, and it describes sun reactivity, not race.

Skin type changes risk.

In darker skin (Fitzpatrick IV to VI), a 2016 review in the Journal of the American Academy of Dermatology found traditional resurfacing, meaning dermabrasion, peels and lasers, carries a higher risk of pigment change and scarring, with microneedling possibly offering a more favorable safety profile.

AAD says people with skin of color can develop permanent pigment problems from chemical peels without an experienced provider, and can have them safely with an experienced dermatologist.

Device labels can carry their own limits.

AAD describes non-invasive skin tightening as safe for people of all skin colors, but that is a general statement: the Morpheus8 90 applicator, for example, is limited to skin types I to IV at energies above 62 mJ per pin.

Ask whether the device and setting planned for you carry a skin-type restriction.

Hair color matters for laser hair removal for the same reason skin type does: the laser targets pigment in the follicle.

Treatment works best on light skin with dark hair; AAD says dark skin and light hair with light skin can be treated but must be done very carefully.

A 2008 paper in the Journal of Cosmetic and Laser Therapy lists blond, white and gray hair as a treatment challenge, because the laser targets melanin.

Some concerns that bring people to a med spa are medical in disguise.

AAD says these should be seen by a dermatologist before any cosmetic treatment: any new, changing, bleeding or itching spot; spots you plan to fade as "age spots"; hair loss, to identify the type; ocular rosacea; and suspected melasma that might be another condition.

The age-spot rule is the most important one on this page.

What looks like an age spot could be skin cancer, and using a fading treatment on a cancer gives it time to grow.

People with light skin who seldom protect it from the sun can also develop actinic keratoses, precancerous growths that AAD says should be seen by a board-certified dermatologist.

Hair loss has several distinct types, each needing different treatment, and AAD stresses a dermatologist diagnosis first because other causes can look like pattern hair loss.

Surgery is sometimes the honest answer.

AAD says a surgical lift gives the most dramatic results for sagging skin, and that with a lot of loose skin, non-surgical tightening may not help.

ASPS describes good body lift candidates as people with significant soft-tissue looseness who are healthy, non-smoking and have realistic goals.

Under the eyes, severe bags from protruding fat and loose eyelid skin are not a filler problem either: a clinical review notes even large amounts of filler cannot camouflage the contour, and those patients may benefit from blepharoplasty (eyelid surgery) to remove or reposition the fat.

A "near me" search returns a map; it does not tell you who is safe.

AAD suggests asking every provider these questions before a cosmetic procedure: Are you board-certified?

How many times have you done this exact procedure?

How often do you treat patients with my skin tone and type, and in my age range?

What results can I realistically expect, with before-and-after photos of similar skin tones?

What are the risks, recovery time, number of treatments and cost?

Who may legally inject you is set by state law, so the answer genuinely is local.

AmSpa, a medical spa trade association, says injecting botulinum toxin is the practice of medicine because a prescription drug is being used to affect living tissue, so it must be done by a physician, an independent-practice NP or another licensed professional acting within their scope, under rules that vary from state to state.

Ask any practice you are considering who will perform your specific treatment and what license that person holds.

AAD's red flags are blunt.

Never get botulinum toxin or filler injections at a non-medical spa, a party, a salon or someone's home, and know that toxin bought online without a medical license differs from what dermatologists use.

At-home microneedling devices and microneedling at a non-medical spa are not meant to puncture the skin and give less noticeable results, and at-home use risks infection, scarring and color change.

And if someone offers to laser-treat a scar without a medical consultation first, AAD's advice is to walk away.

Those checks travel with you: the questions above, the license question, and the red flags are the same vetting in every city, and only a local practice can answer them.
