Product Description

Arrow Down

WHAT IS IT?

Navigating the ups and downs of combination and blemish-prone skin can be tricky. That’s why this naturally blue-hued serum works to regulate sebum production, balance your skin’s microbiome, and clarify your complexion.

WHAT DOES IT DO?

Expertly formulated to nurture your skin’s delicate microbiome back to good health, prebiotics and bioflavonoids are served up alongside vitamin B3 and zinc, which are proven to slow sebum production and refine pores.

Hyaluronic acid keeps skin hydrated, while copper PCA and malachite mineral extracts soothe and nip redness in the bud.

Feisty flare-ups will become a thing of the past.

30ml

Clinical Results

Arrow Down

In a 28-day independent clinical study, users' skin showed an average 36% reduction in excess sebum.

Independent clinical study. Average results after 28 days.

How To Use

Arrow Down

Before moisturising, squeeze 3-6 drops into your palm and dab onto freshly-cleansed skin morning and night.

Use your ring finger to target particularly oily, blemish-prone areas.

Just avoid using Glow Berry at the same time because the vitamin C will counteract Pure Lagoon’s copper PCA.

We recommend using them on alternating mornings for best results.

If you use Fruit Smooth in your routine, we recommend using Pure Lagoon in the morning and Fruit Smooth in the evening.

If you use Eye Work, make sure you apply Pure Lagoon afterwards, to avoid tarnishing the ZAMAC applicator.

    Why Jojoba Oil Is Your Skin's Best Friend

    At the heart of our Smoothing Cleanser is jojoba oil: a golden, skin-loving liquid that closely mimics your skin's own natural oils. That means it deeply cleansers without disrupting your delicate moisture barrier. Rich in vitamins E and B-complex, jojoba oil gently melts away makeup, sunscreen, and daily build-up, while keeping your skin nourished and balanced. It's non-comedogenic (so it won't clog pores), making it ideal for all skin types, from dry and sensitive to oily and blemish-prone. We chose jojoba for its versatility and skin compatibility, but you'll stay for the silky-soft glow it leaves behind.
