WHY A MORNING AND NIGHT SYSTEM
Skin has different needs by day and by night. By day, it needs water, the lipids that keep it in, and antioxidant protection. At night, it repairs and renews itself. The Quartet answers both, with four products used in the right order.
01
MORNING: HYDRATE AND PROTECT.
The Cellular Hydration Serum brings water, the Vitamin C Serum-in-Oil helps keep it in and brings antioxidant protection. No day cream needed.
02
EVENING: CLEANSE AND REHYDRATE.
The cleanser removes the day without stripping the skin, then a serum rehydrates it before the night cream.
03
NIGHT: NOURISH AND STRENGTHEN.
The Exosome Advanced Night Cream nourishes and strengthens the skin barrier with exosomes, for bouncier, more resilient skin by morning.

THE QUARTET ACTIVES
ENCAPSULATED PROBIOTICS
In the Triple Action Cleanser. They help support a balanced skin microbiome and the skin’s natural defences with every cleanse.
HYALURONIC ACID + MAGNESIUM
In the Cellular Hydration Serum, with a patented active that acts on vitamin D receptors, key regulators of the skin’s natural defences.
OIL-SOLUBLE VITAMIN C
In the Vitamin C Serum-in-Oil. Ascorbyl tetraisopalmitate, a stable, non-acidic form of vitamin C, resistant to sun, heat and air.
PROBIOTIC-SOURCED EXOSOMES
In the Exosome Advanced Night Cream. These extracellular vesicles soothe the skin and strengthen the skin barrier, for bouncier, more resilient skin by morning.
WE TEST WHAT ALMOST NO ONE TESTS.
Chemicals (synthetic & natural) can behave differently together than alone. It is called the cocktail effect. So we test the finished formula.
Tested free of estrogenic and androgenic endocrine disruptions.
Why does it work?
Formulated from a cellular health perspective, the Quartet covers the fundamental pillars of healthy skin:
- Cleansing
- Antioxidants
- Skin cell longevity
- Hydration
- Moisturisation
- Skin barrier reinforcement
- Blemishes
- Post-sun relief
QUARTET FAQ
Do I need a day cream as well?
No. In the morning, the Cellular Hydration Serum brings water and the Vitamin C Serum-in-Oil helps keep it in. Finish with sunscreen when exposed to the sun. In the evening, the Exosome Advanced Night Cream is your moisturiser.
In what order do I apply the products?
Morning: Cellular Hydration Serum on slightly damp skin, then Vitamin C Serum-in-Oil, then sunscreen. Evening: Triple Action Cleanser, then 3 to 5 drops of Cellular Hydration Serum (or Vitamin C Serum-in-Oil after a lot of sun or on very dry skin), then the Exosome Advanced Night Cream.
I have sensitive skin. Could the Quartet irritate my skin?
The four formulas are designed to be well tolerated: the cleanser does not strip the skin and the vitamin C is a non-acidic, oil-soluble form. If your skin is very reactive, introduce the products one at a time.
Can I use the vitamin C in the morning, in the sun?
Yes. The form of vitamin C we use is non-photosensitive and resistant to oxidation, so it is made for the morning. Always finish with sunscreen.
Can I use the Vitamin C Serum-in-Oil at night?
Yes, in periods when the skin needs an extra comfort at night or as an after-sun exposure in the summer. We do not recommend at the same time as the CEL Retinal as the combination of both products could be overstimulating for the skin.
Can I use the night cream in the daytime?
Yes, you can use it in the daytime as well, as its light texture is perfect under the makeup. It is free of photosensitive ingredients as well and therefore safe in the morning.
How long will the products last?
The cream and serums last for approximately 3 months. The cleanser, if used once a day, lasts for approximately 1½ months.
Can I use the products separately?
Yes, each product can be used on its own. The Quartet brings them together in the right order, for less than buying them separately.
Are the formulas tested for endocrine disruption?
Yes. Every finished formula is tested, not single ingredients. All four products are tested free of estrogenic and androgenic endocrine disruptions.
