How it works

Retinal: one step closer

Skin must convert any over-the-counter vitamin A to retinoic acid before it works. Retinol needs two conversion steps; retinaldehyde needs one, which is why research associates retinal with visibly faster results at equal tolerance. At 0.01%, this is the gentlest dose in the ladder: a genuine retinoid sized for a first-timer.

The crystal in the name

Retinaldehyde is notoriously unstable, light and air destroy it. Here each molecule is caged in cyclodextrin, a sugar lattice that shields it in the bottle and releases it gradually through the night, flattening the irritation spike that gave retinoids their fearsome reputation.

The support crew

Squalane, hyaluronic acid and glycerin cushion; two vitamin C esters ride along as stabilisers and daytime-defence partners; carrot seed and cloudberry oils bring the vitamin-A-adjacent botanicals. The soft scent is vanilla and tonka, with coumarin declared, noted below.

The ladder logic

Crystal Retinal is designed as a progression: start at 1, and when skin shrugs at it, typically after a bottle or two, step up. Strength is earned, not chosen.

Who it suits

Retinoid first-timers, sensitive skin that has failed retinol before, and anyone starting the vitamin-A half of the CSA routine: C by day, sunscreen always, A by night.

Worth knowing

Not for use during pregnancy or breastfeeding, this applies to every retinoid. Expect possible mild dryness or flaking in the first weeks; it settles. Contains vanilla and tonka extracts with coumarin declared, patch test with a fragrance allergy. Prescription-strength conversations belong with our clinicians.

How to use

Evenings on clean, dry skin: a pea-sized amount over face, avoiding eyes and lips. Start two to three nights a week, building to nightly as tolerated. Moisturiser after if skin runs dry.

High SPF every morning, without exception, retinoids and sun protection are a package deal.

Layering

Use alongside

The night half of the CSA routine, any C-Tetra by day, this by night. Keep Press & Glow or Press & Clear to non-retinal nights while starting out. It shares the entry-retinoid chair with Retinol Brulee and Bakuchiol Complete (the pregnancy-safe alternative): one night retinoid at a time, and the ladder, Crystal Retinal 3, 6, 10, 20, is the upgrade path when skin is ready.

Before you start

Not suitable if

  • You are pregnant
  • Pregnancy or breastfeeding — contains retinaldehyde

  • Do not layer with leave-on acids or other retinoids on the same night

Good to know

  • Patch test on a small area of skin before first full use
  • Increases skin sensitivity to UV. Use broad-spectrum SPF 30 or higher daily
