10 Major Beauty Mistakes That Pros Warn You to Stop Making ASAP

1. Flaky Mascara

Once you’ve — finally! — found the volumizing, lengthening, non-clumping "one," it can be easy to get attached. But makeup artist Kate Lee insists that one of the fundamental aspects of a healthy relationship with your mascara is knowing when to let go. "Once the formula has stopped working, it begins to dry and crack, falling down under the eye. This is a no-no! I buy mascara in twos so that I always have a spare. Mascaras that are used every day are usually drying in three months but definitely done by six," she said.

2. Bronzer Islands

One mistake makeup artist and Kristofer Buckle Cosmetics Founder Kristofer Buckle comes across is when women only apply bronzer on their faces and not their neck and ears. "By doing this, it actually makes you look like you are wearing more makeup because you can see the contrast of the surrounding areas," he explained. "Applying bronzer to the neck and ears gives a healthy seamless look."

3. Foundation Masks

According to makeup artist Kathy Jeung, spotty foundation is also a problem. "Use residual base makeup from your foundation brush or makeup sponge to blend foundation under the chin downwards onto neck to match your made-up face," she said. She also recommended doing an "ear and chest check," and then adding a touch of foundation or concealer to those areas so everything matches.

8. Fumbling Falsies

The same goes with lashes that are too heavy or have glue showing, said Sir John: "If it looks like there’s a critter crawling up your face, that's when it gets sketchy!"

9. Feathered Lips

According to Tanno, nothing is worse than a smudged red lip. "To ensure your pout stays perfect, always powder the outside of your lip line," she noted.

10. SPF Skipping

Last, but certainly not least, make sure SPF isn’t solely reserved for your face. "If your face is four to five shades lighter than your body, it's not a good look temporarily and, in time, the actual condition of the skin will look different. It starts to look like a doll cutout — a Winter head on an August body. Use sun protection everywhere," joked Sir John.
