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, cell renewal peaks, giving active ingredients the best conditions to work. The Quintet answers both, with five 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 RENEW.

The cleanser prepares the skin without stripping it, then the serum targets the signs of ageing with 0.15% encapsulated retinal and the CEL™ Complex.

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 QUINTET ACTIVES

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.

ENCAPSULATED RETINAL + CEL™ COMPLEX

In the CEL™ Retinal Serum. Retinal is one step closer to the active form of vitamin A than retinol. Encapsulated for gradual release, it stays well tolerated, even by sensitive skin. The patent-pending CEL™ Complex helps reduce cellular stress.

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.

QUINTET 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 4 drops of CEL™ Retinal Serum on slightly damp skin, wait 1 minute, then the Exosome Advanced Night Cream.

My skin is sensitive. Can I use the Quintet?

Yes. The cleanser does not strip the skin, the vitamin C is a non-acidic, oil-soluble form, and the retinal is encapsulated for gradual release. The retinal serum was tested on 20 women with sensitive skin, aged 35 to 60. Start the retinal serum every other night for the first 3 weeks, and patch test first. If you have rosacea or eczema in a flare-up, ask your dermatologist before you start.

Will I break out when I start?

A short phase of breakouts can happen when you start a retinoid, as cell renewal speeds up and brings existing spots to the surface faster. It is more common with fast-release retinoids. If it happens, space out the applications rather than stopping.

Can I use it during pregnancy or breastfeeding?

Not the CEL™ Retinal Serum. It contains retinal, and retinoids are not recommended during pregnancy and breastfeeding. Speak to your doctor or midwife.

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 retinal in summer?

Yes, applied at night and with sunscreen in the morning. Retinoids speed up cell renewal, and new skin is more vulnerable to UV. In case of intense sun exposure, space out the applications.

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 Quintet 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 five products are tested free of estrogenic and androgenic endocrine disruptions.

Impressive and effective

I’ve been using the 5 products for a few weeks now and can feel and see its effects. Nothing dramatic but I do notice my skin reacting well and looking fresh and healthy, especially as I am definitely in the ‘mature’ age range!
I wanted a long-term, science-based system and I think this is it.

Satisfaction

J’apprécie la simplicité de la routine, Par contre étant habituée à utiliser une crème, j’ai l’impression que ma est un peu sèche. Par contre concernant les yeux c’est chez moi une zone particulièrement sensible, j’ai eu un épisode eczéma sur le haut de la paupière, je me demande si les protocoles sont donc appropriés pour cette zone. Je vais passer commande du sérum anti-imperfections car j’ai des taches notamment au dessus des sourcils. Je suis impatiente de voir le développement de cette nouvelle marque pour que vais suivre avec attention

J'apprécie la simplicité des produits, les textures, les odeurs, l'utilisation est très agréable et les résultats sont visibles rapidement. La peau est plus lisse, plus ferme, confortable, le teint est plus lumineux.
Le sérum en huile vitamine C un indispensable.
Des cosmétiques qui répondent parfaitement à mes attentes.

Une expérience à part …

Depuis que j’utilise la gamme Skin Diligent je ne suis plus capable de mettre autre chose sur ma peau! De l’expérience sensorielle aux résultats constatés aucun autre produit ne fait le poids ( de l’odeur à la texture en passant par la sensation «  dans ma peau ». Je ne pourrai plus changer de marque 😅. Merci pour la qualité.
