I learned this trick from a fabulous makeup artist at Sephora one day. If you make a mistake when applying makeup, (especially around the eyes), don't use a tissue or makeup sponge to try to fix the problem. This will usually mess up the concealer and foundation as well and then you'll be sitting there trying to patch everything up. Instead, take a cotton swab and dip it in your foundation and use that to dab over your runny mascara, or lipstick then just blend with your fingers and done! Neat , right?
