Product Description

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

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

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.

Ingredients

Bioflavonoids

Bioflavonoids help to fight microbial infections that spiral into spots, so you’re all set to break up with breakouts.

Mineral-rich Polynesian lagoon water

Hydrates and detoxifies the skin, resulting in a clearer and revitalised complexion.

Blue Spirulina

A natural blue-green algae, this not only gives the serum a beautiful blue hue, it’s full of amino acids and minerals that prevent water loss helping to keep skin cool, calm and clear.

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.

It works! Simple as that

Q&A

I have smoothing cleanser besides clear skies powder but if I'm using pure lagoon after cleanse & toner does it still work with smoothing cleanser ? As I know it says after clear skies: Hi Sarah, thank you for getting in touch with us. Yes, our Pure Lagoon will still work if you are using Smoothing Cleanser to cleanse your face. You would apply your Pure Lagoon after you have used your toning essence. We hope this helps!
Do I use Pure Lagoon before or after toner spray?: Hi Sally, thank you for getting in touch. Our Pure Lagoon blemish prevention serum can be used after your cleanser and toner of choice. We hope this helps!
My 13yr old son has been using pure lagoon on his spots but wondering if ocean dive would be better: Hi Joanne, thank you for getting in touch with us. Yes, as our Ocean Dive contains salicylic acid, this will help to decongest and clear the spots and is to be used as a targeted treatment on areas of breakouts, whilst our Pure Lagoon is great to use as an all over treatment to help maintain oil production. We hope this helps.
Is this safe to use in pregnancy?: Hi Rachael, thank you for getting in touch with us. All of our products across all ranges have been independently safety assessed and are safe to use during pregnancy. Ingredients such as salicylic acid and essential oils are used in concentrations that do not constitute any form of pregnancy risk or complications. You can use the search function on our website to view any products with any ingredients of interest. If you have any other concerns due to your individual circumstances such as taking prescribed medication, we recommend consulting your doctor, midwife, or another caregiver. We hope this helps.
I have recently started using your products Blue Lagoon, Super greens, Cleanser, Toner, moisturiser and face mask and My skin is breaking out quite a lot! I had hoped that the products would have the opposite effect. Any advice please? Also, the Blue Lagoon serum is a watery consistency, just wondering if that’s how it’s meant to be?: Hi Paula :) Although our skincare range is 100% naturally derived and is designed to be gentle yet effective on the skin, we do understand that what may work for some, may not work for others, and we will be in touch directly to discuss this further with you. Our Pure Lagoon serum does have a super lightweight, water-like consistency.
I have recently been diagnosed with infected FOLLICULITIS which is spreading over chest, back of legs too. I’ve been referred to a dermatologist but I wanted to ask do you have experience in this kind of condition and what can I do to help myself whilst waiting treatment.: Hi Lisa, thank you for getting in touch with us. We're sorry to hear your have been diagnosed with infected folliculitis. As you have been referred to a dermatologist, we would suggest that you keep your product use minimal until they have given you the best advice and treatment for this. With Folliculitis, it is important to keep the skin exfoliated (not abrasive) and hydrated without aggravating it with scented products so until you have advised by your dermatologist you could use our Rinse and Retreat sensitive body wash. We hope this helps.
