FAQs

The questions our customers and community ask most often!

Does the Perfecting Concentrate need to be rinsed off?

The Perfecting Concentrate treatment is leave-in: apply it to the nail surface and its contour, then massage in for intense nourishment.

When during the day should it be applied?

The Concentré Perfecteur can be applied at any time of day, as often as needed, for perfectly nourished and strengthened nails and cuticles. Its on-the-go pen packaging makes it easy to take anywhere.

Does the Perfecting Concentrate need to be removed?

The Perfecting Concentrate is not removed: it penetrates the surface of the nail and its contour for in-depth care.

Does the Perfecting Concentrate leave a greasy finish?

The Perfecting Concentrate leaves a slightly oily, non-sticky finish.

What are the dimensions and quantity of the product?

The Perfecting Concentrate comes in a pen format of 11 x 3 cm, perfect for slipping into a pocket or bag. It contains 10 mL.

Can pregnant and/or breastfeeding women use the skincare range?

The skincare formulas are green and clean: they are bio-sourced up to 99%, meaning they are made from ingredients derived from biomass such as aloe vera, lemon, ginseng, pomegranate and grape. However, all nail polish, regardless of its nature, should be avoided by pregnant women or breastfeeding mothers. If in doubt, we invite you to consult your doctor.

Can using nail care products cause allergies?

Our care formulas are compliant with European regulations and do not contain sensitising substances. They are also certified gluten-free and safe for people who are gluten intolerant or have coeliac disease, just like the Green Flash™, Green™, and Active™ ranges. Most customers who have experienced allergies with conventional nail care products do not have any with the Manucurist care range. However, since allergic reactions are not exclusively linked to synthetic ingredients, they can sometimes occur with plant-based ingredients as well. If you have any doubts, we advise you to consult your doctor.

For more information, we recommend reading our blog post on allergies.

IT WORKS!

"I took time t write this review waiting to see results, I have had issues with my nails i guess due to gel manicures, I can honestly say i have never seen my nails looking good for a very long time. They were dry and brittle with ridges all over. I love the peel off witch leaves my nails hydrated and smooth, then the cuticle glides over so smoothly and sinks in leaving a healthy looking nail. I am really impressed and show off my bear nails without any embarrasment."

— Sarah C. (5/5)

Still a little early to

"Still a little early to say. However, 3 weeks in I do see some improvements. My nails were constantly splitting and catching on things. I made the decision to cut them extremely short and start using the Manucurist Stronger Nails Duo. This has definitely helped. The smell of the treatment is really nice! The only thing I notice now is my thumb nails are still chipping and splitting. However, not as badly as they use to. Still early days but appears to be making a difference!"

— Layla D. (5/5)

Strength and moisture for frequent handwashers

"My nails love this stuff. I work as a barista so my hands and nails get very dry (and beat up) during the workday from frequent handwashing. They've obviously gotten stronger with consistent use. A little goes a long way and I just purchased my second tube after a year with the first one"

— Nicola (5/5)

Thank you!

"Thank you!"

— Laura L. (5/5)

Nails and cuticles serum arrived

"Nails and cuticles serum arrived defective. The bottle doesn't close, it's impossible to use the brush because the serum simply doesn't get in there, it's impossible to take with you because the bottle cap falls off and the serum spills out in your bag."

— Tatsiana T. (2/5)

Vey good
