Using a microdermabrasion machine involves short, controlled strokes across clean skin while the device exfoliates the outer layer of dead cells and vacuums them away. The technique is straightforward, but getting the pressure, pattern, and frequency right makes the difference between glowing results and irritated skin.
Know Your Machine Type
Home and professional microdermabrasion machines come in two main varieties, and they work differently enough that it matters which one you have.
Diamond-tip machines use a wand with a diamond-coated tip that physically buffs the skin while a built-in vacuum suctions away dead cells. The tip stays on the wand, so there’s no mess. You can swap between coarser and finer tips depending on the area you’re treating, which makes these especially useful for delicate zones around the eyes and mouth. Diamond-tip devices are the most common type sold for home use.
Crystal machines shoot a stream of fine crystals (usually aluminum oxide or sodium bicarbonate) onto the skin, then vacuum the crystals and dead skin cells back up. The intensity is adjusted by changing the flow rate of crystals. These tend to be messier but often less expensive. If you have a known aluminum allergy, use a sodium bicarbonate crystal or switch to a diamond-tip system entirely.
Prep Your Skin Before Each Session
Start by washing your face with a gentle cleanser and patting it completely dry. The machine needs to glide across bare, dry skin. Any moisture, oil, or product residue will reduce suction and make the exfoliation uneven.
In the days leading up to your session, stop using retinoids (Retin-A, Differin, retinol serums), glycolic acid products, and any other strong exfoliants. These thin the outer skin layer, and combining them with mechanical exfoliation raises your risk of irritation and redness. Most guidelines recommend pausing these products for at least 48 to 72 hours beforehand.
Step-by-Step Technique
Work in sections: forehead, each cheek, nose, chin, and neck. Within each section, use short strokes of one to two inches. Longer strokes can be too abrasive and cause unnecessary sensitivity. Keep the wand moving at all times. Holding it in one spot concentrates the suction and exfoliation, which can bruise or damage the skin.
For diamond-tip machines, place the tip flat against your skin so you get full contact and consistent suction. Pull the skin slightly taut with your free hand, then glide the wand in one direction. Most people work in upward and outward strokes, following the natural contours of the face. Go over each section once or twice on your first few sessions. You can add a third pass as your skin builds tolerance.
For crystal machines, hold the handpiece about half an inch from the skin and let the crystal stream do the work. You don’t need to press into the skin. Start on the lowest crystal flow setting and increase only if your skin handles it comfortably.
Use a gentler touch (fewer passes, lower suction, finer tip) on thin skin around the eyes, lips, and sides of the nose. The neck is also more sensitive than the face, so you may want to divide it into upper and lower halves and treat each with lighter pressure.
Suction and Intensity Settings
If your machine has adjustable suction, always start at the lowest level during your first session. Too much vacuum pressure won’t give you better results. It will leave you with redness, broken capillaries, or small bruises. Increase the suction gradually over multiple sessions as you learn how your skin responds. Oily or thicker skin generally tolerates higher settings than dry or thin skin.
The same principle applies to tip coarseness on diamond machines. Begin with the finest grit tip included with your device. Coarser tips are meant for tougher areas like elbows or heels, or for experienced users treating stubborn texture on the forehead and cheeks.
Who Should Avoid Microdermabrasion
Do not use the machine on skin with an active infection, including cold sores (herpes simplex), warts, or impetigo. The abrasion and suction can spread the infection to other areas of your face. Active, inflamed acne is also a problem: dragging a wand across raised breakouts can rupture them and worsen scarring.
Rosacea and visible spider veins (telangiectasias) are relative contraindications, meaning the treatment may be possible at very low settings but carries a higher risk of flare-ups. If you have a history of keloid scarring, where scars become raised and overgrown, proceed with extra caution, as even minor skin trauma can trigger new keloids.
Cleaning the Machine After Use
Proper cleaning between sessions prevents bacterial buildup on the tips and tubing. After each use, remove the diamond tip or crystal tip from the handpiece. Wipe the tip and any non-immersible electrical parts with a cloth dampened in warm water and a mild detergent. Rinse by wiping with a cloth dampened in hot water, then dry everything thoroughly. Finish by wiping all surfaces with a cloth dampened in 70 percent rubbing alcohol and let them air dry completely before storing.
For crystal machines, empty the used-crystal canister after every session and check the filters. Clogged filters reduce suction power and make the treatment less effective. Most manufacturers recommend replacing filters every five to ten sessions, but check your specific model’s instructions.
Aftercare That Protects Your Results
Your skin will be more sensitive and more absorbent for 24 to 48 hours after a session. This is the window where aftercare matters most.
Apply a gentle, hydrating moisturizer immediately after treatment to lock in moisture and calm the skin. Avoid retinoids, alpha hydroxy acids, beta hydroxy acids, and any other active exfoliants for at least a week. These can cause stinging and irritation on freshly exfoliated skin. If you wear makeup, choose mineral-based products that are less likely to clog pores while your skin is recovering.
Sun protection is non-negotiable. Freshly exfoliated skin burns faster and is more prone to hyperpigmentation. Apply a broad-spectrum sunscreen with at least SPF 30 before going outside, and reapply every two hours if you’re staying in the sun. Drinking plenty of water also helps your skin recover, since hydration from the inside supports the barrier repair happening on the surface.
How Often to Use It
Spacing sessions correctly is one of the most important parts of using a microdermabrasion machine safely. Your skin needs time to rebuild its protective barrier between treatments, and doing sessions too close together leads to chronic irritation, persistent redness, and increased sensitivity.
For oily or thicker skin, treatments can typically be done every two weeks. For sensitive, dry, or thinner skin, every four to six weeks is a safer interval. If you’re targeting specific concerns like uneven tone, mild acne scars, or fine lines, starting with a series of sessions spaced about two weeks apart tends to produce the best initial results. After that initial series, maintenance sessions every one to two months are usually enough to keep the results going.
Home machines are generally less powerful than professional-grade devices, but that doesn’t mean you should use them more aggressively. If you notice lingering redness, peeling, or tightness lasting more than a day after treatment, extend the time between your sessions and reduce the intensity next time.
