Something I feel anyone that loves makeup must have is a good sized bottle of baby shampoo. The brand doesn't really matter but the two I use most often are Johnson's and the store brand from Target. There are honestly so many uses for this simple product and you'll spend a heck of a lot less cash on this one bottle than you would on the different products you would need to get the jobs done.
Eye Makeup Remover
Though it's not my #1 way of removing makeup properly, this really does the trick. Not only is it gentle and good to your skin, but it says right on the front of the bottle "No More Tears" so it won't bother your eyes like some removers can. Put about a quarter-sized amount on your hand and rub around your eyes. Remove the product with you a warm washcloth. Just remember to keep your eyes closed! Even though it says no more tears, if you get it directly into your eye it's going to irritate it.
Cleaning Makeup Brushes
Since it works so well gently removing makeup from your eyes, baby shampoo will be just as gentle on your makeup brushes. It is baby shampoo, after all, so you can be assured that it will not only clean but leave your brushes of any fiber or hair feeling soft and undamaged. Again, you'll want to use about a quarter-size amount in the palm of your hand and rub the brushes flat and one at a time on your palm. Rub the shampoo into both sides and rinse with water.Flick the brush briskly a few times to water and be sure to lay the brushes on a flat surface so the excess water doesn't drip down into the brush.
Shaving
The baby shampoos that I buy are all hypoallergenic and are dermatological and allergy tested. Therefore, it's gentle and doesn't' irritate sensitive skin. Though it isn't as thick as shaving gel or lather too nicely, it's a good alternative to shaving products that may cause redness, breakouts, and irritation. The shampoo softens the hair you are shaving and leaves the skin soft as well. It's especially great for underarms and bikini areas since the hair is usually coarse.
Replacing Several Items When Traveling
Instead of finding travel-sized versions of eye makeup remover, brush cleaner and shaving gel, you can consolidate more space in your makeup bag by buying a $1 3oz travel bottle from a drugstore and filling it with the baby shampoo.
