We recommend applying the Sins 'n Lashes eyebrow serum in the first week once a day, in the evening before going to bed on the skin and eyebrows. From the second week you can apply the eyebrow serum 1 to 2 times a day (morning & evening) to achieve fantastic results in 6 weeks!

Make sure skin is clean before application. If it is forgotten one day, then the application can simply be continued the next day.


Our best ingredients

Pumpkin Seed Extract - Rich in zinc, amino acids and vitamins, helps balance lashes and make them look fuller.

Biotin - contains vitamin B7 and vitamin H. It is an essential factor in maintaining healthier looking lashes.

Panthenol - contains vitamin B5, which helps coat lashes with moisture and nutrients, improving their overall appearance.

Swertia Japonica Extract - extracted from the Swertia Japonica plant, contains high concentrations of natural flavonoids and antioxidants that stimulate hair growth.

Panax ginseng - has been used in traditional Chinese medicine for centuries. Ginseng contains two important substances: ginsenosides and gintonin.
