Fifteen actives, one honest format

This hub is the reference shelf for what is actually in your routine. Fifteen ingredient deep-dives, from workhorses like retinol, niacinamide and vitamin C through to newer arrivals like bakuchiol, tranexamic acid and snail mucin, each written to the same format: the science, which skin types it suits, our top product recommendations, and the questions readers ask most.

The format is deliberate. The science section keeps claims to what the evidence supports, the skin-type section stops you buying an active that will fight your skin, and the recommendations carry the same Glow scores and Australian prices as our category rankings. Where an ingredient crosses into prescription territory, the explainer says so plainly: the tretinoin guide covers prescription-strength retinoic acid and what separates it from the retinol you can buy off the shelf.

• Match the active to the concern before you shop. Pigmentation, congestion and dehydration each point to a different explainer.
• Read the skin-type section before the recommendations if your skin is sensitive. That is what it is there for.
• The acids are not interchangeable. Salicylic, glycolic, mandelic and azelaic each have their own guide, so check the one you are actually buying.
• Hydrators and barrier ingredients matter as much as the headline actives. The hyaluronic acid and ceramide guides cover the supporting cast.
• Each explainer ends with a common questions section for the routine details, so read it before asking whether two actives can share a shelf.

Start with what is retinol, then what is niacinamide, described in our guides as the gentlest of the proven actives.
