A
- AHAs (Alpha Hydroxy Acids): Chemical exfoliants that gently dissolve dead skin cells on the surface (e.g., glycolic acid, lactic acid). These ingredients can improve skin texture, brightness, and reduce wrinkles.
- Acne: A skin condition characterized by clogged pores, pimples, blackheads, and whiteheads.
- Active Ingredients: Ingredients in a skincare product formulated to address specific skin concerns. Examples include retinol for wrinkles, hyaluronic acid for hydration, and salicylic acid for acne.
- Antioxidants: Ingredients that fight free radicals, which are harmful molecules that damage skin cells and contribute to aging. Common skincare antioxidants include vitamin C, vitamin E, and green tea extract.
- Ascorbic Acid: Pure form of vitamin C, a potent antioxidant that brightens skin and protects against free radical damage. Can be irritating to sensitive skin.
- Astringent: Ingredients that tighten pores and reduce oil production. Examples include witch hazel (use diluted on oily skin) and hamamelis virginiana extract.
B
- Benzoyl Peroxide: An anti-bacterial ingredient commonly used to treat acne by killing acne-causing bacteria.
- BHAs (Beta Hydroxy Acids): Chemical exfoliants that penetrate deeper into pores to clear clogged pores and combat acne (e.g., salicylic acid).
- Ceramides: Lipids naturally found in the skin that help strengthen the skin barrier and prevent moisture loss. Skincare products often contain ceramides to improve barrier function and hydration.
- Comedones: Clogged pores, which can appear as whiteheads (closed comedones) or blackheads (open comedones).
- Comedogenic Rating: A scale that ranks ingredients based on their likelihood of clogging pores (0 – non-comedogenic, 5 – highly comedogenic). This scale can be a helpful guide, but individual skin sensitivity can vary.
C
- Chemical Exfoliants: Use acids (AHAs or BHAs) to dissolve dead skin cells on the surface of the skin.
- Cleanser: A product used to remove dirt, oil, makeup, and impurities from the skin. Cleansers come in various forms, such as creams, gels, foams, and micellar water.
- Combination Skin: Skin type with oily areas (typically T-zone) and dry areas (cheeks).
D
- Dermatologist: A medical doctor specializing in diagnosing and treating skin conditions.
- Dry Skin: Skin type that lacks moisture, often characterized by tightness, flaking, and roughness.
- Dyes: Coloring agents added to skincare products for aesthetic purposes, but offer no skincare benefits. Can be irritating to sensitive skin.

- Essential Oils: Concentrated, plant-derived liquids with various therapeutic properties. Some essential oils can be irritating to the skin and should be used diluted.
F
- Fatty Acids: Essential components of the skin barrier that help maintain hydration and protect against environmental damage. Examples include linoleic acid and oleic acid.
- Free Radicals: Unstable molecules that damage skin cells and contribute to premature aging. Antioxidants help neutralize free radicals.
- Fragrance: Adds scent to skincare products but can irritate sensitive skin. Fragrance-free products are a good choice for those with sensitive skin.
G
- Glycerin: A humectant that attracts and retains moisture in the skin.
- Glycolic Acid: An AHA that gently exfoliates dead skin cells, improving texture, brightness, and reducing fine lines.
H
- Hyaluronic Acid: A humectant that attracts and retains moisture in the skin, leaving it plump and hydrated.
- Humectants: Ingredients that attract and retain moisture in the skin. Examples include hyaluronic acid, glycerin, and aloe vera.
I

- INCI (International Nomenclature of Cosmetic Ingredients): The standardized system for naming cosmetic ingredients on product labels.
L
- Lotion: A lightweight, water-based moisturizer.
M

- Mineral Sunscreens: Sunscreens that contain physical blockers (e.g., zinc oxide, titanium dioxide) which sit on the surface of the skin and deflect UV rays. These are generally considered gentler on sensitive skin.
- Moisturizer: A product that hydrates the skin and helps maintain the skin barrier function. Moisturizers come in various textures (lotions, creams, gels) to suit different skin types.
O
- Occlusive: Ingredients that form a protective barrier on the skin to prevent moisture loss. Examples include petrolatum, dimethicone.
- Oily Skin: Skin type characterized by excess oil production, often resulting in a shiny appearance and enlarged pores.
P
- Patch Testing: The practice of applying a small amount of a new skincare product to a small area of skin (usually the inner forearm) to check for any allergic reactions before using it on the entire face.
- Peptides: Short chains of amino acids that signal the skin to produce more collagen, which can reduce wrinkles and improve firmness.
- Physical Exfoliants: Use abrasive ingredients like sugar crystals or walnut shells to scrub away dead skin cells. These can be too harsh for some skin types and may cause irritation.
- Preservatives: Ingredients added to skincare products to prevent the growth of bacteria and fungi, ensuring product safety and shelf life. Examples include parabens, phenoxyethanol.
R
- Retinol: A derivative of vitamin A that promotes cell turnover, reduces wrinkles, and improves skin texture. Retinol can be irritating to some skin types, so it’s important to start slowly and introduce it gradually into your routine.
