The Keen Tonic recipe Over 56 super ingredients. For more results.

Your skin needs a healthy and varied diet to be healthy. We don't believe that a single ingredient can offer a miracle result! Wouldn't we think of eating only carrots to get a glowing complexion? That's why we include more than 56 organic plants in Keen Tonic, so that all skin types can get the nutrients that really work for them at all times. Your skin doesn't have the same needs and the same little problems to deal with every day. By offering a variety of 100% natural ingredients, it has all the cards in its hand to draw what it needs every day, according to its current needs.

Its difference

It's the first aqueous serum to act simultaneously on hydration, signs of aging and imperfections! Concentrated in Aloe Vera and plant waters, this serum deeply moisturizes without clogging pores. With Hyaluronic Acid and 18 plumping extracts, your skin regains tone and suppleness. Finally, because there's no age to be prone to imperfections, its formula is enriched with plants that gently regulate and detoxify your skin to get rid of pimples.

Its use 

Keen Tonic can be used every day, alone or before your cream, in the morning and/or evening. After cleansing your face, apply 2 to 3 drops of the plumping and balancing serum with your fingertips to your entire face and neck. Gently tap with your fingertips to help the active ingredients penetrate. You can complete your routine with a cream moisturizer such as Glow Up, Check Matte or Age Out depending on your skin's needs.

Tip from the skin chef Anne-Marie

Coline and I created this skincare product for those who love Aloe Vera gel and Hyaluronic Acid. The idea is, of course, to enhance these 2 beautiful ingredients with a combination of 50 active ingredients to boost hydration and plump the skin, while at the same time having a regulating effect. Just 2 small drops are all you need to apply to your face, tapping until the product is absorbed.

I love it

I've completely adopted Keen Tonic into my routine! My skin feels plumper, hydrated and with fewer imperfections. What's more, I love its texture, which reminds me of aloe vera gel, which is really fun to apply.

My new must-have!

I discovered this serum and I love it! It smoothes my first small wrinkles but above all it's very effective for my hormonal acne, I have far fewer pimples and they disappear faster.
The serum is very fresh and goes well under make-up!
