Bakuchiol is a natural meroterpene compound obtained from the plant extract of Babchi seed (Psoralea corylifolia), a cosmeceutical active ingredient often marketed as a "natural retinol alternative" that induces retinol-like transcriptional gene expression patterns without directly activating the retinoid receptor.
Chemical peeling is a topical or clinical active treatment method based on peeling and renewing the skin surface in a controlled manner. It is an aesthetic dermatology procedure that provides acne, hyperpigmentation, fine lines and skin texture improvement by accelerating keratinocyte turnover through hydroxyl acids (AHA, BHA, PHA) and enzymes.
Exilis Ultra is an FDA 510(k) approved zero-downtime non-invasive body contouring and facial tightening combination device produced by BTL Aesthetics, delivering 1-3 MHz monopolar radiofrequency (RF) and 2 MHz ultrasonic energy simultaneously, providing real-time impedance control with Proteus technology, for sub-dermal 4-10 mm deep fat tissue heating and dermal collagen coagulation.
Fractional CO2 laser; Carbon dioxide laser beam with a wavelength of 10,600 nm is fractionated to form heated microthermal zones (MTZ) and provides ablation (evaporation) and deep dermal remodeling on the skin surface. It is the laser treatment with the strongest indication for acne scars, signs of aging and skin texture improvement.
HIFU (High-Intensity Focused Ultrasound) is an FDA-approved medical device as a non-invasive alternative to surgical face-lift, based on triggering thermal coagulation and subsequent neocollagenesis by converting 3-10 MHz focused ultrasound energy into 65-70°C temperature points in the SMAS (Superficial Musculoaponeurotic System) layer in the subcutaneous layers.
Moisturizer is a topical product that reduces the skin's trans-epidermal water loss (TEWL) and supports the skin barrier; It is a daily skin care product that should be selected and applied according to skin type, in lotion/cream/balm/ointment format, divided into three basic component categories: occlusive (prevent water loss), humectant (absorb water) and emollient (soften).
Hyaluronic acid (HA), the active ingredient used in dermal fillers, is a high molecular weight glucosaminoglycan polymer composed of β-1,4-D-glucuronic acid and β-1,3-N-acetyl-D-glucosamine repeating disaccharide, occurring naturally in the body; It is the most commonly used filler in facial filler in aesthetic injections, increasing skin hydration and volumetricity.
IPL (Intense Pulsed Light) is a device that uses non-coherent, polychromatic (420-1200 nm wide spectrum) beam produced by xenon flashlamp and is a non-laser photoenergy source that targets certain chromophores (hemoglobin, melanin, water) with the principle of selective photothermolysis; Medical device used in the treatment of pigmentary and vascular lesions, photorejuvenation, hair removal and rosacea.
Keloid is a red-purple colored, itchy and non-shrinking pathological scar that exceeds the original wound boundaries as a result of TGF-β1 overexpression, fibroblast proliferation and apoptosis imbalance and uncontrolled accumulation of type I and type III collagen during the healing process after skin injury; It is the most common irchitic dermatological condition between the ages of 10-30, with an incidence of 16% in individuals of African origin and 0.09% in whites.
Morpheus8 is a fractional RF microneedling medical device produced by InMode Aesthetic Solutions, which will transmit bipolar radiofrequency energy to the subdermal layer at a depth of 1-8 mm through an insulated microneedle array (12-40 pins), performs thermal remodeling in the dermis collagen and subdermal adipose tissue, and is used for facial contouring, skin tightening and body contouring with Subdermal Adipose Remodeling (SART) FDA approval.
Niacinamide (nicotinamide) is the amide form of Vitamin B3 and is the active ingredient in cosmeceutical serums that strengthens the skin barrier, provides sebum regulation, inhibits melanin transfer and supports collagen synthesis; As a NAD+/NADP+ precursor, it is active in cellular energy metabolism.
Peptide serum are cosmeceutical active substances consisting of short-chain amino acid sequences (typically 2-50 amino acids, mostly 3-6), which trigger collagen and elastin synthesis, inhibit neurotransmitter release or prevent enzymatic degradation; They form the main component of the bulk in topical serum formulations used against signs of aging (wrinkles, loss of skin tension, fine lines).
