If you have long hair, you should pull it back into a ponytail or bun so that it doesn't get in the way. Make sure you moisten your entire face. It is best to use warm water, but avoid using water that is too hot: that can dry out your skin. Take a dab of the scrub and massage it all over your face and neck. Be careful not to rub too hard, so that you can avoid unnecessary redness or peeling. Also be particularly careful not to get the scrub in your eyes. Note that rubbing for more than 60-90 seconds might cause irritation or sensitivity. Be sure that you are not over-scrubbing or leaving the scrub on your face for too long. Make sure you get it all off. When you rinse all of it off, your skin will feel very smooth and soft. Gently pat your skin dry with a soft towel and continue with the rest of your skin care routine. Even if you have oily or combination skin, moisturizing is a necessary part of a skin care routine, especially after exfoliating with a facial scrub. Moisturizing helps to prevent the overproduction of skin oils and keeps the skin healthy and well-balanced. It might be tempting to get that soft, glowing feeling every morning. However, using a facial scrub too often can peel away your delicate skin cells and leave you feeling red, raw, and sore. Try using the scrub only once a week at first; you can increase the frequency to twice a week if you feel like your skin can handle it. Moderation is key to the effectiveness of a facial scrub.
