Let’s break it down simply:

Best for: Dullness, uneven tone, fine lines, surface dryness
Water-soluble – works on the skin’s surface

Glycolic Acid (from sugar cane)
– Smallest molecule, deeply exfoliates, boosts collagen
Lactic Acid (from sour milk or fermented vegetables)
– Hydrating, brightens skin, gentle on sensitive types
Mandelic Acid (from bitter almonds)
– Antibacterial, great for acne-prone or sensitive skin
Malic Acid (from apples)
– Mild exfoliator, also hydrates
Tartaric Acid (from grapes or wine)
– pH-balancing, antioxidant support
Citric Acid (from citrus fruits)
– Brightens and smooths, often used to balance pH

Best for: Oily skin, clogged pores, acne
Oil-soluble – penetrates into pores

Salicylic Acid (from willow bark)
– Deep-cleans pores, reduces inflammation and breakouts
Betaine Salicylate (from sugar beets + salicylic acid)
– A gentler alternative to salicylic acid, hydrating + exfoliating

Best for: Sensitive skin, rosacea, barrier support
Large molecules – gentle, non-irritating exfoliation

Gluconolactone (from corn or glucose fermentation)
– Hydrates, strengthens barrier, antioxidant-rich
Lactobionic Acid (from milk sugar – lactose)
– Very hydrating, supports skin renewal, great for aging skin
Galactose (a type of sugar found in milk)
– Mild exfoliation, hydrates, antioxidant properties

Derived from wheats, barley & rye, think of it as a "bonus acid" that blends the best of all categories!

What it does:
– Gently exfoliates
– Reduces redness (rosacea-friendly)
– Fights acne-causing bacteria
– Helps fade hyperpigmentation
– Supports the skin barrier
Who it's for:
– Sensitive, acne-prone, rosacea-prone, or uneven skin tone
Gentle enough for daily use, and often paired with other acids.
