This category groups concepts for definition and clinical context. Inclusion is not a personal treatment recommendation or a candidacy decision. Only entries that pass editorial-depth, evidence and patient-safety checks are listed; treatment decisions require an examination and review of medical history.
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.
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.
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).
Retinol is the pre-vitamin form of Vitamin A1 (C20H30O), which is metabolized into retinal and retinoic acid in the skin and provides increased cellular turnover, collagen synthesis stimulation, melanin inhibition and anti-photoaging effects through nuclear receptors, and is the gold standard anti-aging active ingredient of the cosmetic industry.
Toner is a liquid product that balances the pH of the skin after cleansing and acts as a residue cleaner. It is divided into the categories of traditional astringen (alcohol-based, for aged skin) vs modern hydration tonic (glycerin + hyaluronic acid) vs exfoliating tonic (AHA 4-7%, BHA 2% — active exfoliating agent).
Vitamin C serum is a cosmeceutical serum formulation containing L-ascorbic acid or its derivatives (sodium ascorbyl phosphate, magnesium ascorbyl phosphate, tetrahexyldecyl ascorbate); It is a dermocosmetic topical product class that provides anti-aging, brightening and UV protective effects with its antioxidant, collagen synthesis stimulating and melanin inhibition properties.
