In-office treatments

Chemical peels apply an acid solution to remove controlled layers of skin, from surface-only superficial peels (glycolic, salicylic, mandelic) to medium-depth TCA peels. They are among the oldest procedures in dermatology and have decent trial support for acne and melasma, with glycolic acid the best studied. The main honest caveat is durability: pigment conditions like melasma recur at high rates once peeling stops, and superficial peels do little for actual wrinkles despite frequent anti-aging peel marketing.

Cryolipolysis cools pinched folds of fat to temperatures that kill fat cells while sparing skin and nerves, and the dead cells clear gradually over 2 to 3 months. Meta-analyses support a real but localized effect: measurable reductions in fat thickness and circumference in treated spots, including about a 2 to 3 mm reduction in under-chin fat, with high satisfaction. It does not cause weight loss and is not an obesity treatment, and buyers should know about paradoxical adipose hyperplasia, an uncommon complication where the treated area grows firm and larger instead of shrinking.

Fractional CO2 is the heavyweight of skin resurfacing: a 10,600 nm laser vaporizes thousands of microscopic columns of skin, leaving intact tissue between them to speed healing. It has the strongest evidence in this category for atrophic acne scars, where meta-analyses show it beats both Er:YAG lasers and RF microneedling, and solid trial support for wrinkles. The trade-off is real downtime and the highest pigmentation risk of the common devices, especially in darker skin.

HIFU focuses ultrasound energy to heat tissue at precise depths (1.5 to 4.5 mm) under the skin without breaking the surface, aiming to tighten the same fibromuscular layer a facelift addresses. A meta-analysis of 17 studies supports real but modest lifting and tightening of the lower face, brow, and neck. It is the classic case of marketing outrunning effect size: nonsurgical facelift branding suggests surgical-scale change, while pooled improvement scores land around 2.7 on a 5-point scale.

HydraFacial is a branded hydradermabrasion device that combines vortex suction exfoliation with simultaneous infusion of serums (acids, antioxidants, peptides). It is a pleasant, no-downtime facial with immediate short-term glow, and that is roughly what the evidence supports: a 20-person study from 2008 and a small uncontrolled acne series are the core of the peer-reviewed literature. For a treatment marketed this aggressively, the published data is remarkably thin; no randomized controlled trial supports lasting change in wrinkles, pores, or pigmentation.

IPL is not a laser but a broad-spectrum flash lamp with filters that target hemoglobin (redness) and melanin (brown spots). Its best evidence is for the redness and visible vessels of rosacea and for sun-induced brown spots, where multiple trials show meaningful clearance over 3 to 5 sessions. For wrinkles and acne the data is thinner, and photofacial marketing tends to promise full-face rejuvenation that the studies only partially back up.

Laser hair removal targets melanin in the hair follicle with pulses of laser light, and it is one of the best-evidenced cosmetic procedures: controlled trials and meta-analyses consistently show 50 to 85 percent long-term hair reduction after a series of treatments. The key honest correction to marketing is the word removal: the evidence supports lasting partial reduction, not guaranteed permanent elimination of all hair, and results depend heavily on hair color (dark hair responds, white and blonde hair barely does).

LED therapy exposes skin to non-thermal red (around 630 to 660 nm), blue (around 415 nm), or near-infrared light. The evidence is genuinely mixed by indication: modest but real trial support for mild to moderate acne and for pattern hair loss, and thinner, shorter-term data for wrinkles. The consumer mask and panel market has sprinted far ahead of the science; most trials are small, under 12 weeks, often industry-funded, and home devices frequently deliver lower doses than the units studied.

Microneedling uses a roller or motorized pen studded with fine needles to punch hundreds of controlled micro-injuries into the skin, prompting a wound-healing response that builds new collagen. It is one of the better-studied minimally invasive procedures: a 2022 meta-analysis of 12 randomized trials supports it for atrophic acne scars, where it performs about as well as chemical peels but below fractional lasers. Evidence for wrinkles and melasma is thinner and mostly comes from small trials or studies where microneedling is paired with topical drugs.

PRP concentrates platelets from your own blood and injects or microneedles them into skin or scalp, delivering a payload of growth factors. The strongest evidence is for pattern hair loss, where multiple meta-analyses of RCTs show significant hair density gains. For facial rejuvenation the story is weaker: a systematic appraisal of 36 studies covering 3,172 patients concluded the clinical evidence is very limited, largely because preparation methods vary wildly between studies and clinics. The vampire facial hype exceeds the facial data considerably.

RF microneedling adds heat to standard microneedling: insulated or non-insulated needles deliver radiofrequency energy directly into the dermis at set depths. The evidence base has grown quickly, with dozens of studies including 15 or more RCTs across indications, and it looks genuinely useful for acne scars and mild skin laxity. That said, head-to-head data show fractional CO2 laser still beats it for acne scars, and the dramatic nonsurgical facelift framing used to sell devices like Morpheus8 runs well ahead of what the studies measured.
