A miracle solution for beautiful nails every day.

Our IN & OUT treatment has been trending in the world of cosmetics for some time.
We're taking a closer look at this new beauty trend to help you understand what it's all about.


What is IN & OUT?

IN & OUT beauty is a new way of taking care of yourself all over. It's about pairing food supplements (IN) with nail care products (OUT) that work together to meet your specific daily needs.

Why add food supplements to your nail care routine?

Like hair and skin, nails are complex structures that need certain elements to thrive. These elements are provided almost exclusively by food. Simply put, our nails reflect what we eat.

Rest assured that almost everyone suffers from some form of deficiency. It's difficult to have a perfectly balanced diet that provides all the minerals, vitamins and amino acids you need. These deficiencies affect how the nail grows and it can become weaker over time.

The aim of IN & OUT is to offer a targeted solution with maximum effect that treats the cause as well as the symptoms.



The nail care products (OUT) work locally or "topically": the active plant ingredients they contain work directly on the nail to correct temporary problems.
The food supplements (IN) provide the high concentration of vitamins, minerals and amino acids needed by the nail for optimal, problem-free growth.
Convinced? So are we!

Your IN & OUT nail care routine

We have developed a complete IN & OUT routine to care for your nails from the inside and outside. This routine combines the topical action of a treatment base coat with the overall effectiveness of food supplements. We wanted to offer a routine tailored to every nail type, which is why you can choose your own base coat.

OUT: How to apply your treatment base coat


Step 1 - Remove the oil from your nails using a gentle, acetone-free nail polish remover.

Step 2 - For maintenance, apply the base coat on its own or underneath the Green colour of your choice to strengthen your nails.
As a repair treatment, apply twice a week for healthy, regenerated nails.

IN: How to take Nail Boost


As an intensive treatment

For damaged nails (dull, soft and lacking resistance), you should take the food supplements as an intensive treatment: 4 capsules a day for 1 month.

Good to know: Nail Boost capsules are not chemically concentrated, which is why you can take 4 capsules a day. You are then advised to move on to a maintenance treatment of 2 capsules a day for 2 months. Repeat 2 to 3 times a year.

As a preventative treatment

For nails that need a bit of a boost, the supplements can be used as a preventative treatment. Two capsules a day is enough. You can repeat the preventative treatment 2 to 3 times a year as needed.

TeaM tip: if you don't like swallowing capsules, empty the powder into a spoonful of fruit puree or yoghurt. Easy!
