What Are Whiteheads?
Have you heard the term "closed comedones?" That's the technical name for these pimples, and it actually provides good info about what whiteheads are. "Comedones" are pores that are clogged with oil, bacteria and dead skin cells. "Closed" refers to the fact that there is a layer of skin over all that nasty stuff. The white spots in the center of your pimples are the pore-clogging culprits trapped beneath the skin. These pimples are not typically inflamed or painful.

What Causes Whiteheads?
Sometimes, there is something you're doing that is leading to whiteheads. For example, leaving makeup on all night, not washing your pillowcase often enough or pressing your phone against your face could be responsible for your breakouts. Some people get pimples in relation to hormonal fluctuations, particularly along the cheeks, chin and jawline.

How to Remove Whiteheads
Almost all dermatologists will tell you not to pop your whiteheads. This type of whitehead removal could spread infection or cause scarring. Topical products will clear them eventually, but if you're feeling impatient, visit the dermatologist, who can perform an in-office extraction.

How to Get Rid of Whiteheads for Good
Changes to your beauty routine can clear up the breakouts you have and keep new whiteheads away.

Clean deeply: An electronic cleansing device can really help keep your pores clean. Pair the Clarisonic Mia 2, $169, with a gentle cleanser, such as Cetaphil Gentle Skin Cleanser, $13.99, for a deep clean that won't irritate skin.

Apply benzoyl peroxide: To kill acne bacteria and get rid of whiteheads, apply benzoyl peroxide. Spot-treat with a topical product like Clean and Clear Persa-Gel 10, $4.97, or use a benzoyl peroxide wash, such as Panoxyl 10% Acne Foaming Wash, $9.49.

Exfoliate with two acids: You've probably heard of using salicylic acid for zits, but glycolic acid is another chemical with exfoliating powers. Peter Thomas Roth Max Complexion Correction Pads, $40, contain both ingredients. In addition to the acids' chemical exfoliation, you'll also get physical exfoliation from the pads' textured side.

Use the right makeup: Breakout-prone skin can react unpleasantly to the ingredients in some makeups. Be kind to your skin by selecting an oil-free foundation whose very first ingredient is water. Neutrogena SkinClearing Liquid Makeup, $14.09, fits the bill and also contains salicylic acid for an acne-fighting punch.

See the dermatologist: If you're having trouble getting your whiteheads under control, go to a professional. A dermatologist can help you find the whitehead removal treatment that's best for your particular skin needs. He or she may prescribe a retinoid to use in addition to your other skincare products.
