Ultimate Glossary

The Skincare
Ingredient Dictionary

Not all chemicals are bad. Discover exactly what each active compound does, how it interacts with the skin barrier, and why it matters for teen breakouts.

Chemical Exfoliant

Salicylic Acid

AKA: Beta Hydroxy Acid (BHA)

Salicylic acid is a beta hydroxy acid (BHA) naturally derived from willow bark. Unlike Alpha Hydroxy Acids (AHAs) which only work on the very surface of the skin, BHAs are strictly oil-soluble. This unique chemical property allows salicylic acid to bypass the oily surface of your skin and penetrate deep into the pore lining to physically dissolve trapped sebum and dead skin cells.

Barrier Repair & Antioxidant

Niacinamide

AKA: Vitamin B3 / Nicotinamide

Niacinamide is a highly stable, water-soluble form of Vitamin B3. It is universally recognized in cosmetic dermatology for its unparalleled ability to work gently alongside other powerful active ingredients (like Retinols and Acids) while actively mitigating and reversing the irritation those ingredients typically cause.

Acne Treatment

Benzoyl Peroxide

AKA: BPO

Benzoyl Peroxide is an organic peroxide that acts as an antimicrobial peeling agent. When applied to the skin, it releases oxygen inside the pores, creating an environment where the C. acnes bacteria (the primary bacteria responsible for inflamed acne) physically cannot survive.

Hydrator

Hyaluronic Acid

AKA: HA, Sodium Hyaluronate

Hyaluronic acid is a naturally occurring glycosaminoglycan found throughout the body's connective tissue. In skincare, it acts as a 'humectant' -meaning it works like a biological sponge that actively draws water from the environment (or the deeper layers of skin) straight to the surface epidermis.

Barrier Repair

Ceramides

AKA: The Skin Barrier Building Blocks

Ceramides are waxy lipid molecules (fats) that exist naturally in the outermost layer of your skin. If your skin cells are bricks, ceramides are the extremely important mortar that holds them together, forming a waterproof seal that keeps dangerous bacteria out and vital moisture inside.

Acne Treatment & Brightener

Azelaic Acid

AKA: AzA

Azelaic acid is a naturally occurring dicarboxylic acid produced by yeast that lives on normal skin. It is truly a multi-tasking powerhouse: it gently exfoliates, acts as a powerful antibacterial agent against C. acnes, and specifically suppresses the enzyme (tyrosinase) that causes dark hyperpigmentation.

Soothing Agent

Centella Asiatica

AKA: Cica / Tiger Grass / Gotu Kola

Centella Asiatica is an ancient medicinal herb heavily popularized by Korean skincare (known colloquially as “Cica”). Its active compounds (madecassoside, asiaticoside) are clinically proven to drastically accelerate wound healing and slash severe inflammatory skin responses.

Sebum Regulator

Zinc PCA

AKA: Zinc Pyrrolidone Carboxylic Acid

Zinc PCA is a trace mineral (Zinc) biologically bound to PCA (Pyrrolidone Carboxylic Acid, a molecule naturally found in the skin). This incredible fusion allows the Zinc to easily penetrate the skin to kill bacteria while the PCA binds massive amounts of surrounding atmospheric water to hydrate the skin.

Chemical Exfoliant

Glycolic Acid

AKA: Alpha Hydroxy Acid (AHA)

Glycolic acid is a water-soluble Alpha Hydroxy Acid (AHA) derived from pure sugarcane. It has the smallest molecular weight of all AHAs, allowing it to rapidly penetrate the very top layer of the skin (the stratum corneum) to dissolve the glue-like bonds holding dead, dull skin cells together.

Cellular Turnover Accelerator

Retinol

AKA: Vitamin A

Retinol is the over-the-counter precursor to Retinoic Acid (Vitamin A). It is considered the closest thing to real magic in dermatology. When absorbed, it physically enters your skin cells and alters their behavior, forcing them to rapidly divide, shed, and pump out massive amounts of fresh structural collagen.

Soothing & Barrier Repair

Panthenol

AKA: Vitamin B5

Panthenol is a stable water-soluble form of Vitamin B5. Once applied, it rapidly converts into pantothenic acid inside the skin, where it binds powerfully to water to improve elasticity and aggressively repair a damaged skin barrier.

Non-Comedogenic Hydrator

Squalane

AKA: Plant-Derived Squalene

Squalane is a highly stable, hydrogenated version of Squalene, a lipid (oil) that occurs entirely naturally in our own human skin. Because it is completely skin-identical, our skin instantly recognizes and absorbs it without sitting on top acting greasy.

Antioxidant & Brightener

Vitamin C

AKA: L-Ascorbic Acid

L-Ascorbic Acid (pure Vitamin C) is the most potent and proven topical antioxidant in skincare. It furiously fights free radicals -unstable molecules from UV rays and pollution that rip apart our skin’s collagen and cause early degradation.

Chemical Exfoliant

Lactic Acid

AKA: AHA / Milk Acid

Lactic Acid is an Alpha Hydroxy Acid historically derived from sour milk. Because its molecule size is significantly larger than Glycolic Acid, it cannot penetrate the skin fully, making it work much slower and incredibly gentler on the very surface layer.

Natural Antibacterial

Tea Tree Oil

AKA: Melaleuca Alternifolia

Tea Tree Oil is a powerful essential oil distilled directly from the leaves of the native Australian Melaleuca plant. It has been used for centuries purely for its proven antiseptic, antibacterial, and massive anti-inflammatory properties.
