What's doing the work

Lactic Acid#2 of 15

A gentler AHA that exfoliates and hydrates simultaneously. Near the top of the list — present at a meaningful level. Research supports 5–12%.

Glycerin#3 of 15

The most effective and affordable humectant in skincare. Near the top of the list — present at a meaningful level.

Hyaluronic Acid#7 of 15

A humectant that holds 1000x its weight in water for instant plumping. Mid-list — present, but not the headline of this formula. Research supports 0.1–2%.

Where it goes

After cleansing, before moisturiser.

☀️ MORNING · 🌙 EVENING

Don't layer with

Retinol — because this contains Lactic Acid.

Salicylic Acid — because this contains Lactic Acid.

Benzoyl Peroxide — because this contains Lactic Acid.

Using them in the same routine is usually fine — it's applying them together, in one layer, that causes the problem. Check against your own routine →
