The routine, step by step

What each mask does

  • Collagen Mask : this ultra-hydrating hydrogel mask combines collagen, hyaluronic acid and niacinamide. It intensely hydrates and skin looks bouncier. It appears suppler, skin texture looks refined and the complexion looks more luminous.
  • Bakuchiol Mask : this hydrogel mask brings together bakuchiol, hydrolysed collagen and hyaluronic acid. It intensely hydrates the skin, which looks smoother. It appears bouncier and suppler, with a more luminous complexion.

Two masks for comfortable, hydrated skin : by alternating them each week, you give your skin intense hydration and a real moment of softness. A complete, easy-to-follow routine for skin that looks bouncier, suppler and more luminous week after week.

How to use this duo?

Here's how to use both masks to get the most out of them:

Once a week, after thoroughly cleansing your skin, apply one of the two masks, alternating between them: the Collagen Mask one week, the Bakuchiol Mask the next.

Apply to clean skin and leave on for at least 4 hours, ideally overnight.

Collagen Mask: when you wake up, your skin is well hydrated, looks bouncier and appears more luminous.

Bakuchiol Mask: when you wake up, your skin looks rested and smoother, and your complexion appears more luminous.

My favourite anti-ageing ritual

I'm 38 and with daily stress + Parisian pollution, my skin had lost all its radiance. Greyish complexion, fine lines getting deeper, basically I looked 5 years older. I'd already tried loads of pharmacy masks and even salon treatments at £80 a session, without lasting results. A colleague told me about this duo and I gave it a go. I do the collagen mask on Sunday evenings, I apply it before bed and it becomes transparent overnight. On Monday morning my skin is plumped, radiant, my features look rested like after a spa weekend. The bakuchiol I do on Wednesday evenings, it's more focused on firmness and honestly after 4 weeks my face contour is more defined. I alternate the two and it's become my me-time. At the office people asked if I'd changed my cream, I was so pleased. I'm on my 3rd order, I couldn't do without it now.

Results ok but application not straightforward

Right so on results I won't lie, my skin is indeed more hydrated and complexion a bit fresher when I wake up. But the application really put me off. The mask slides loads when you apply it, you have to stay still for a good quarter of an hour until it sticks. And sleeping with it is honestly not comfortable, I woke up several times the first few nights because it was peeling off. The PDF guide that's supposed to come with the duo is very light, there's hardly anything in it. For the price of the pack I expected something more comprehensive. I'll finish my masks because the result the next day is still there, but I'm not totally convinced by the format.

Answer: MySosBeauty

Bonjour Safia, un masque qui se décolle la nuit a généralement été posé sur une peau encore humide ou mal plaquée : séchez le visage, ajustez chaque section au relief sans l'étirer, puis attendez dix minutes avant de vous coucher. Autre option, le poser en soirée et le retirer au coucher.

    A marvel!

    This collagen mask is a gem!

    I have very very dry skin and really struggle to find products that hydrate me deeply without leaving a sticky feeling on my face.

    I tested this mask during the day for 4 hours, the result was already very satisfying and my skin well hydrated.

    I wanted to fully follow the recommendations by sleeping with it, despite my apprehension about the mask staying put and being uncomfortable during my sleep, but here's my feedback after this test:

    1. It didn't bother me at all and it didn't move all night (see photos)!

    2. When I woke up my skin was incredible, deeply hydrated with a glow I've never had!

    3. A shower of compliments on my skin from my colleagues that morning. 🥹

    I'm so happy to have finally found a mask with a real result on my skin's hydration. I'm going to order a stock and do 1 mask per week without hesitation! 😍

    My favourite

    I was already using the brand's moisturising collagen mask, but the special anti-ageing bakuchiol mask is my new favourite! It smoothes the skin really well and has a lovely rose scent. I also alternate with the yellow one for radiance, which is great too!

    My Sunday ritual that's become essential

    With work stress and turning 35, my skin was really looking dull. Lacklustre complexion, fine lines deepening around my eyes, basically I looked tired every time I looked in the mirror. I started with the collagen mask one Sunday evening, left it on all night. The next morning I was gobsmacked: plumped skin, rested features, a glow I hadn't had for years. I now alternate the two masks each week — the collagen for deep hydration and the bakuchiol for firmness. In a month my skin has completely changed texture, it's smoother, more bouncy. At the office I was asked if I'd had injections 😂 Better than the salon treatments I was paying a fortune for, honestly. I've already reordered the duo, I couldn't do without it now.
