octinoxate is an organic (chemical) ultraviolet (UV) filter used in many sunscreens and daily-wear cosmetic products. It primarily helps reduce UVB exposure, which is the portion of sunlight associated with sunburn. It is most commonly found in cosmetic skincare and makeup products that include sun protection claims. It may also appear in peri-procedure skincare routines in cosmetic and reconstructive care where sun protection is emphasized.

avobenzone is an organic (chemical) ultraviolet (UV) filter used in many sunscreens. It primarily protects against UVA radiation, which is associated with photoaging and pigment changes. It is commonly used in cosmetic skincare products and in sun protection plans discussed around aesthetic procedures. It is not a surgical material or implant, and it is not used for reconstruction by itself.

chemical sunscreen is a topical product that helps protect skin from ultraviolet (UV) radiation using UV-absorbing ingredients. It is commonly used in everyday skincare and in peri-procedure skin care around cosmetic and reconstructive treatments. It typically comes as a lotion, gel, fluid, spray, or stick applied to exposed skin. In clinical contexts, it is discussed as part of photoprotection for healing skin, scar care, and pigment management.

titanium dioxide is an inorganic mineral compound commonly used as a white pigment and light-scattering agent. In skincare, it is widely used as a physical (mineral) UV filter in sunscreens. In cosmetics, it helps create opacity, brightness, and a more even-looking finish. In clinical settings, it may appear as a component of topical products, medical device materials, or product coatings used in cosmetic and reconstructive care.

zinc oxide is an inorganic mineral compound used in many skin and medical products. It is commonly used on the skin as a physical sunscreen filter and as a protective barrier cream. It is used in both cosmetic skincare (including makeup and sunscreens) and clinical care (including wound and irritation protection). It also appears in some medical and dental materials, depending on the product and manufacturer.

alpha arbutin is a topical skincare ingredient used to help reduce the look of uneven skin tone. It is a plant-derived compound and a glycosylated form of hydroquinone used in cosmetic formulations. It is most commonly used in non-surgical aesthetic skin care rather than reconstructive surgery. It may be recommended as part of pigment-management routines before or after aesthetic procedures, depending on clinician preference.

licorice extract is a botanical ingredient derived from the root of *Glycyrrhiza* species (commonly *Glycyrrhiza glabra*). It is used most often in topical skincare products and sometimes in oral supplements. In cosmetic care, it is typically included for skin tone support and soothing properties. It may be used in both everyday cosmetic routines and adjunctive care around dermatologic or aesthetic treatments.

tranexamic acid is a medication that helps reduce bleeding by stabilizing blood clots. It is classified as an antifibrinolytic, meaning it slows the natural breakdown of clots. In cosmetic and plastic surgery, tranexamic acid is commonly used to support hemostasis (bleeding control) around procedures. In dermatology and aesthetic medicine, tranexamic acid is also used in some cases for pigment concerns such as melasma.

arbutin is a skin-brightening ingredient used in topical skincare products. It is a plant-derived compound (a glycoside) that is commonly included in creams and serums for uneven skin tone. In cosmetic practice, it is most often discussed for facial hyperpigmentation and discoloration concerns. It is used in non-surgical cosmetic skincare rather than reconstructive surgery.

kojic acid is a skin-lightening ingredient used to help reduce the look of uneven pigmentation. It is most commonly found in topical skincare products and some clinician-directed regimens for hyperpigmentation. It is derived from certain fungi and can also be produced through fermentation processes. Its use is primarily cosmetic, but it may be discussed in reconstructive contexts when discoloration follows inflammation, injury, or surgery.

hydroquinone is a topical medication used to reduce unwanted skin darkening (hyperpigmentation). It is most commonly used in cosmetic dermatology and aesthetic care to help fade dark spots and uneven tone. It may also be used around reconstructive and plastic surgery care when pigmentation changes affect the appearance of scars or treated areas. It works on pigment formation rather than physically removing skin.

sulfur (topical) is a skin-applied (topical) ingredient used in dermatology and skincare. It is commonly formulated into cleansers, lotions, creams, masks, and medicated soaps. It is used mainly for inflammatory or scaly skin conditions that affect appearance and comfort. It may be used in cosmetic skincare routines and, in some cases, alongside reconstructive care when skin health affects healing or scar appearance.

– benzoyl peroxide is a topical (skin-applied) medication used most commonly to help treat acne. – It is an oxidizing agent that reduces acne-causing bacteria on the skin surface and within follicles. – It is widely used in cosmetic dermatology and general dermatology to improve acne-related skin clarity. – It may also be used in selected pre-procedure skin-prep routines when clinicians want to reduce follicle bacteria, depending on the setting.

salicylic acid is a beta-hydroxy acid (BHA) used to exfoliate skin and help clear pores. It is commonly found in over-the-counter and prescription skincare products for acne and oily skin. In aesthetic medicine, it is also used as a chemical peeling agent to improve texture and tone. It is used in cosmetic care more often than reconstructive care, but may support overall skin management in both settings.

lactic acid is a naturally occurring organic acid made by the body during normal metabolism. In skincare, lactic acid is an alpha-hydroxy acid (AHA) used to exfoliate and improve the look and feel of skin. In cosmetic medicine, related materials derived from lactic acid (such as poly-L-lactic acid) are used in certain injectable and absorbable medical products. It is used primarily in cosmetic care, with some roles in reconstructive and surgical materials through its polymers.

glycolic acid is an alpha hydroxy acid (AHA) most commonly used to exfoliate the skin. It is used in topical skincare and in-office chemical peels to improve skin texture and tone. In cosmetic dermatology and aesthetic medicine, it is primarily used for resurfacing rather than reshaping. It may also be used in some reconstructive settings as part of scar and pigment management plans.

growth factors (topical) are skin-applied products that contain growth factors or growth factor–like signaling ingredients. They are used to support skin renewal and the appearance of healthier-looking skin. In aesthetic medicine, they are most often discussed as adjuncts to skincare or procedure aftercare. They may be used in cosmetic contexts and, in some settings, as part of reconstructive wound-care discussions.

peptides are short chains of amino acids, which are the building blocks of proteins in the body. In aesthetic medicine, peptides most commonly refer to skincare ingredients designed to support specific skin functions. In reconstructive and surgical settings, peptides may also appear in wound-care or healing-support products, depending on the material and manufacturer. They are not a single “procedure,” but a category of biological molecules used across cosmetic and reconstructive care.

ceramides are waxy lipids (fats) that are naturally present in the outer layer of skin (the stratum corneum). They help form the skin barrier that keeps water in and irritants out. In clinical and cosmetic care, ceramides are most commonly used topically in moisturizers, cleansers, and barrier-repair products. They are relevant to both cosmetic care (skin quality, texture, tolerance of procedures) and reconstructive care (supporting compromised or healing skin).

hyaluronic acid (topical) is hyaluronic acid formulated to be applied on the skin rather than injected. It is a water-binding (humectant) ingredient used to improve skin hydration and surface smoothness. It is most commonly used in cosmetic skincare, and it is also used in some clinical skin-care regimens. It does not “fill” tissue like injectable hyaluronic acid; it works at the skin surface and upper layers.
