Le Rouge Français has revealed its 400 Médusa Natural, Organic Brow & Lash Booster which coats, protects and strengthens to boost the growth of eyelashes and browns.  

The formula contains clover and mung bean extract to stimulate growth, castor oil to strengthen and Roman camomile floral water to soothe skin. The serum should be applied in the morning before mascara and in the evening after removing makeup.  

In a 56-day clinical trial, 100% of participants agreed that there was an improvement in the appearance of their eyelashes and eyebrows and 90% found that the serum stimulated growth.  

The serum contains ingredients which are 99.5% natural and does not contain any synthetic fragrance, BHT, BHA, silicones, squalene or animal-derived ingredients.  

The Médusa Natural, Organic Brow & Lash Booster is available now at John Bell & Croyden, £33 RRP.
