Acne treatment is chosen by lesion type and severity, not by device: comedonal acne, inflammatory acne and nodulocystic acne respond to different first-line therapies, and in-clinic procedures are generally adjuncts to medical treatment rather than replacements for it. Updated 17 September 2026. Korean Plastic Surgery Research Desk. Korean clinics offer an unusually wide menu of acne programmes, often packaged under proprietary names that obscure what is actually being used.

RF microneedling delivers radiofrequency energy through insulated needles into the dermis, while traditional microneedling creates mechanical injury alone. The added heat is what allows RF devices to target laxity and deeper scarring, and it is also what raises the risk profile in darker skin. Updated 17 September 2026. Korean Plastic Surgery Research Desk. Korean clinics market both technologies under a large number of device and programme names, which makes direct compariso

Updated 16 September 2026. Korean Plastic Surgery Research Desk. Quick Answer Question Short answer What determines the result Depth of penetration, not the brand or programme name Best first peel for acne-prone skin Salicylic acid, because it is lipid-soluble and reaches sebaceous follicles Best general starting point Glycolic acid for dullness, rough texture and mild uneven pigment For photodamage and stubborn pigment TCA at medium depth, with materially higher risk Main ri

Updated 16 September 2026. Korean Plastic Surgery Research Desk. Quick Answer Question Short answer Best wavelength for darker Asian skin Nd:YAG at 1064 nm, because epidermal melanin absorbs it least Most common choice in Korean clinics Diode at roughly 800 to 810 nm, a practical middle ground When alexandrite suits Lighter skin with dark hair, broadly Fitzpatrick I to III What it cannot treat Grey, white, red and fine vellus hair, which lack usable pigment Correct terminolog

Exosome skin therapy uses nanoscale vesicles secreted by cells - typically carrying proteins, lipids, and RNA - applied topically after a micro-channelling procedure to influence skin repair signalling. In Korea it is usually an adjunct treatment, not a standalone one. Exosome treatments have moved quickly from research to clinic menus, and marketing has outpaced published evidence. The claims range from reasonable to implausible, and prospective patients rarely get a clear a

Subcision, TCA CROSS, and fractional laser treat acne scars in different ways: subcision releases tethering beneath rolling scars, TCA CROSS remodels narrow ice-pick scars chemically, and fractional laser resurfaces the surrounding skin texture. The single most common mistake in acne scar treatment is choosing a modality before identifying the scar type. Most faces carry a mixture - rolling, boxcar, and ice-pick scars often coexist, sometimes alongside post-inflammatory pigme

Toxin treats movement lines, filler treats volume loss. A zone-by-zone decision framework, the static-versus-dynamic test, sequencing rules and the safety differences between the two.

The three retinoids differ by how many conversion steps skin must perform before they become active. A mechanism-first comparison, with guidance for pigment-prone Asian skin.

What picosecond pulse duration actually changes, which pigment responds, realistic session counts, and the hypopigmentation risk clinics understate.

The mechanism behind PDRN and polynucleotide skin treatment, what the evidence supports, a realistic session protocol, and who should not expect much.

CO2 and erbium lasers both resurface skin but deposit heat very differently. Here is how that changes tightening, downtime and — critically for Asian skin — post-inflammatory hyperpigmentation risk.

A sequenced anti-aging framework for the 40s: sun protection and retinoids first, then pigment control, collagen stimulation and conservative volume support — with a method for telling what actually worked.

The Fitzpatrick skin type scale classifies skin from I to VI based on how it responds to ultraviolet exposure, and it is used in laser medicine as a first-pass proxy for how much melanin will compete with the laser's intended target. That proxy is the single most important safety variable in energy-based treatment, and it is also the one most often skipped in consultation. Melanin absorbs light across much of the wavelength range used in aesthetic lasers. When a device is set

Tranexamic acid and hydroquinone treat melasma through different mechanisms: hydroquinone suppresses pigment production inside the melanocyte, while tranexamic acid interrupts the signalling between blood vessels, inflammation and melanocytes that keeps melasma switched on. That mechanistic split matters because melasma is not simply excess pigment. It is a chronic condition involving vascular, hormonal and barrier components, which is why a single-agent approach so often pro

Mole removal in Korea is usually performed with a carbon dioxide laser, an electrosurgical device, a shave technique, or a full surgical excision, and the choice determines both the scar and whether the tissue can be examined under a microscope. Clinics often present removal as a cosmetic service priced per lesion, which obscures the more important question: has anyone determined what the lesion actually is before deciding how to remove it. This guide explains how benign lesi

Vascular lasers treat facial redness by delivering light that is absorbed preferentially by haemoglobin, heating the blood vessel until it collapses while leaving the surrounding skin largely intact. Pulsed dye lasers, potassium titanyl phosphate lasers, long-pulsed neodymium-doped yttrium aluminium garnet lasers, and intense pulsed light devices are all used for this purpose, and Korean clinics commonly offer several of them under trade names rather than technical ones. They

Non-surgical rhinoplasty in Korea is the injection of hyaluronic acid filler into the nose to change its contour without surgery, most often to smooth a dorsal hump, raise a low bridge, or lift a drooping tip. It is quick, reversible, and popular. It is also, by consensus in the aesthetic literature, one of the highest-risk sites on the face for vascular complications. Those two facts are rarely presented together in a consultation. This guide explains what filler can realist

A hair transplant in Korea is a surgical procedure that relocates hair follicles from a genetically resistant donor area, usually the back and sides of the scalp, into thinning or bald regions. The transplanted follicles generally retain the characteristics of where they came from, which is why donor quality matters more than the name of the technique. The choice between FUE, FUT, and non-shaven variations is often presented as a choice between modern and outdated methods. It

Collagen stimulators are injectable products that work by provoking the skin to make its own collagen rather than by adding volume directly, as hyaluronic acid filler does. The two main categories used in Korean clinics are poly-L-lactic acid and calcium hydroxylapatite, with polydioxanone and poly-D,L-lactic acid products increasingly marketed alongside them. They behave differently from filler in onset, duration, reversibility, and complication profile, and they are frequen

Masseter botox is an injection of botulinum toxin into the masseter, the chewing muscle at the angle of the jaw, to reduce its bulk and soften a square lower face. In Korea it is one of the highest-volume non-surgical facial procedures, partly because muscular jaw prominence is common and partly because it is often presented as the only alternative to bone surgery. It works well for one specific finding and does very little for two other causes of a wide lower face. This guid
