Description

Complete Day & Night Routine – 7 days to visibly repair soft, damaged nails. A targeted two-step regimen combining the power of two expert treatments:

Keratin Booster :
The miracle hardening treatment that strengthens and regenerates soft or damaged nails instantly.

10% concentrated treatment formula:

  • Plant Keratin: supports the restructuring of the nail’s keratin
  • Gluconolactone & AHAs: gently exfoliate the nail plate
  • Silicon: helps reinforce the nail
  • Biotin (Vitamin B8): helps strengthen and harden the nail
  • Vitamin C: protects the nail from external stressors

Its fluid texture is instantly absorbed by the nail for deep-down action.

Proven visible results:
Nails felt harder (85%*)
Nails felt stronger (81%*)
Nails were less likely to split (81%*)

*Clinical test under dermatological supervision on 25 individuals after 2 weeks of use.

S.O.S. Mask:
An intensive overnight mask to repair and strengthen severely damaged nails.

Its unique formula, highly concentrated in emollient and fortifying agents, creates a protective film over the nail surface to support cellular repair while you sleep.

Nails feel harder, deeply hydrated, and visibly stronger by morning.

How to use the Day & Night Routine?

Your complete 7-day treatment to repair soft, damaged nails:

  • Keratin Booster : Apply 1 to 3 times a day to bare nails using the brush applicator. Allow to dry completely for full absorption. Repeat daily for 5 to 7 days.
  • S.O.S. Mask : Apply 2 to 3 times a week in the evening to bare nails, in a generous layer. Leave to air dry. In the morning, remove by peeling off or with soapy water.

FAQ

Our Frequently Asked Questions from our customers and community!

What nail care products are best suited to my nail type?

Every nail type is different! Complete our online nail analysis to help you select the most suitable nail care products.

We can then offer you a nail care programme tailored to your needs!

Can pregnant and/or breastfeeding women use your nail care range?

Our nail care formulas are green and clean: they are up to 99% plant-based, i.e. made from biomass ingredients like aloe vera, lemon, ginseng, pomegranate and grape. However, women should avoid all types of nail polish when they are pregnant or breastfeeding. We recommend you speak to a healthcare professional if you are unsure.

Can using your nail care products cause allergies?

Our nail care formulas meet European standards and do not contain any sensitising substances. They are also certified gluten-free and safe for people with gluten intolerance or celiac disease, as are our Green Flash™, Green™ and Active™ ranges. Most customers who are allergic to regular nail care products are not allergic to the Manucurist nail care range. However, as allergic reactions are not specifically linked to chemical ingredients, they can sometimes occur with plant-based ingredients. We recommend you speak to a healthcare professional if you are unsure.

For more information, see our blog on allergies.
