I have been wearing Lancôme mascara for 20 years. Every time I stray and try a new brand, I go right back. It has the perfect brush and formula. Never clumpy and can layer and layer. The brush works like a dream. It removes easily too.
Switched to Lancome because of flaking from other brands that were incredibly irritating to wearing contact lenses. I love them all (Defincils, Monsieur Big, Hypnose). Switched back to Hypnose because it's buildable and have found more volume at the base of my lashes looks more natural.
