Scar treatment is the set of methods used to improve the appearance and symptoms of scars left by acne, surgery or injury; the method is chosen by scar type — fractional laser, radiofrequency microneedling, microneedling, subcision, TCA CROSS and fillers for depressed (atrophic) scars, and silicone, intralesional injection and laser for raised (hypertrophic/keloid) scars.
Skin cleanser is a skincare product that removes sebum, sweat, make-up, dirt and environmental pollution from the facial skin with pH-compatible surfactants; It is in foam, milky, micellar, oil-based or balm form and fulfills its cleaning duty by protecting the skin barrier.
SkinSpan and similar biological skin-age (bioage) measurement systems are commercial laboratory/clinical tests that quantitatively measure the skin's <em>biological</em> age against its <em>chronological</em> age through a combined assessment of epigenetic DNA methylation biomarkers (Horvath clock, Hannum clock, GrimAge and PhenoAge derivatives), telomere length, advanced glycation end-products (AGEs), oxidative-stress markers and dermatoglyphic AI image analysis.
SPF (Sun Protection Factor) is a numerical indicator that measures the degree of protection of the skin from the UVB spectrum of sun rays. SPF 30 filters 97% of UVB rays, and SPF 50 filters 98%, through chemical (avobenzone, octinoxate, organic) or physical (zinc oxide, titanium dioxide, mineral) UV filters; broad-spectrum protection (UVA + UVB) and regular renewal (2 hours) are required.
Swelling (Postprocedural Edema), increased vascular permeability after the aesthetic procedure, capillary fluid leakage mediated by inflammatory mediators (histamine, bradykinin, prostaglandin), hydroscopic effect of hyaluronic acid fillers and interstitial fluid accumulation as a result of lymphatic drainage impairment, temporary or prolonged tissue volume and swelling; It is a postoperative complication that is divided into pitting (fluid dominant, curable) and non-pitting (fibrotic, permanent risk), shows maximum incidence in the lip and peri-orbital regions, peaks in 48-72 hours, and resolves spontaneously in 95% within 7-14 days.
