- Acne Mechanica
- Acne caused by sustained friction, pressure, and heat against skin — helmet straps, chin straps, backpack straps. Prevented by moisture-wicking liners and prompt cleansing.
- Acne Vulgaris
- Common acne — a chronic inflammatory condition of the pilosebaceous unit. Involves excess sebum, follicle blockage, Cutibacterium acnes bacteria, and inflammation.
- AHA (Alpha-Hydroxy Acid)
- Water-soluble chemical exfoliants (glycolic, lactic, mandelic) that loosen dead skin cells on the surface. Improve texture, tone, and fine lines. Require acidic pH to work and increase UV sensitivity.
- Alpha Arbutin
- A stabilised derivative of hydroquinone that inhibits tyrosinase to slow melanin production. Gentler than hydroquinone, used for hyperpigmentation at 1–2%.

- Ingredients that neutralise free radicals before they damage skin cells. Vitamin C, vitamin E, ferulic acid, and niacinamide are antioxidants. Most effective applied in the morning before UV exposure.
- Ascorbic Acid (Vitamin C)

- Atopic Dermatitis (Eczema)
- A chronic inflammatory skin condition characterised by dry, itchy, inflamed skin. Often related to filaggrin gene mutations and a compromised skin barrier. Worsened by triggers like stress and certain detergents.
- Azelaic Acid
- A naturally-occurring dicarboxylic acid with anti-inflammatory, anti-bacterial, and tyrosinase-inhibiting effects. Treats acne, rosacea, and hyperpigmentation. OTC to 10%; prescription at 15–20%.
