Microdermabrasion is a non-invasive exfoliation treatment that removes the outermost layer of dead skin cells, leaving skin smoother, brighter, and more even-toned. The visible difference between before and after is often noticeable even after a single session: skin looks fresher and feels softer, with a subtle glow replacing dullness. Over a series of treatments, the changes go deeper, with studies showing dermal thickness increases of up to 40% and collagen-bundle thickness increases of around 22%.
How the Procedure Works
There are two main types. Crystal microdermabrasion sprays fine crystals onto the skin through a handheld device, then vacuums them away along with loosened dead cells. Diamond-tip microdermabrasion uses a wand with a diamond-coated tip that physically buffs the skin while a vacuum removes debris simultaneously. Both accomplish the same goal, but diamond-tip systems are generally gentler and allow more precision, making them a better fit for sensitive skin or delicate areas around the eyes and nose.
A session typically takes 30 to 60 minutes. The sensation is often compared to a cat licking your face or fine sandpaper being moved across the skin. It’s not painful, though some areas may feel more sensitive than others.
What Your Skin Looks Like Before
People seek microdermabrasion for a range of concerns. Common “before” complaints include dull or rough texture, uneven skin tone, clogged or enlarged pores, superficial acne scars, sun damage spots, and fine lines. The skin often looks flat or tired, lacking that reflective quality that comes from a smooth surface. Hyperpigmentation patches may be visible, and makeup may settle unevenly into textured areas.
What Changes After One Session
Immediately after treatment, your skin will be pink or slightly red, similar to a mild windburn. This redness fades within a few hours for most people. You may also notice your skin feels tight or mildly sensitive to the touch.
Once the initial flush subsides, usually by the next morning, you’ll see the first real difference. Skin appears brighter and feels noticeably smoother. Pores look smaller because the layer of dead cells that was stretching over them is gone. Any dullness from buildup is replaced by a more luminous, even surface. Many people describe their skin as “glowing” for several days after a single treatment.
Fine lines won’t disappear after one session, and deeper acne scars will still be visible. But surface-level roughness and minor discoloration show immediate improvement.
Results After Multiple Sessions
The more significant before-and-after transformation happens over a series of treatments. For concerns like acne scarring or stubborn pigmentation, weekly sessions are typically recommended during the initial phase. Once the skin has responded, results can last up to three months before a maintenance session is needed.
The reason repeated treatments work better comes down to what’s happening beneath the surface. Research using skin biopsies has shown that microdermabrasion produces real structural changes: epidermal thickness increased by about 9%, while dermal thickness (the deeper, supportive layer) increased by as much as 40% in thinner skin and 27% in thicker skin. Collagen-bundle thickness grew by roughly 22%. These are the same types of tissue-level changes seen after laser resurfacing and chemical peels, just achieved more gradually and with less downtime.
After a full treatment course, the cumulative before-and-after difference is more dramatic. Skin tone becomes more uniform, fine lines soften, shallow scars flatten, and overall texture improves. The skin feels firmer because of the increased collagen density underneath.
Recovery and Downtime
Microdermabrasion has minimal downtime compared to more aggressive resurfacing procedures. Redness and mild sensitivity typically resolve within a few hours to a day. Some people experience light flaking or peeling for two to three days as the skin renews itself. This is normal and shouldn’t be picked at or scrubbed away.
Your skin is more vulnerable to sun damage immediately after treatment because the protective outer layer has been removed. Broad-spectrum sunscreen with at least SPF 30 is essential every day during the healing window and beyond. For the first 24 hours, skip makeup, strenuous exercise, and anything that causes heavy sweating. Avoid exfoliating products, retinoids, and glycolic acid for at least a week to prevent irritation on freshly treated skin.
Stick to gentle, fragrance-free cleansers and moisturizers during recovery. Hydrating options like soothing ointments, petroleum jelly, or simple natural oils can help keep the skin comfortable without triggering a reaction. Drinking extra water also supports the healing process from the inside.
How to Prepare Before Treatment
Preparation makes a real difference in how your skin responds. In the days leading up to your appointment, stop using aspirin-based products, retinoids (like tretinoin or adapalene), and glycolic acid products. These thin the skin or increase sensitivity, raising the risk of irritation during the procedure. If you’ve had facial waxing recently, wait until the skin has fully calmed before scheduling a session.
Arrive with clean skin, free of makeup and heavy moisturizers, so the device can work directly on the surface without a barrier.
Who Should Skip Microdermabrasion
Not every skin condition responds well to this treatment. If you have active acne breakouts, a rosacea flare, eczema, psoriasis, sunburn, or any open wounds, microdermabrasion can worsen inflammation and slow healing rather than improve things. These conditions weaken the skin’s protective barrier, making exfoliation counterproductive.
People with bleeding disorders, diabetes, or those taking blood-thinning medications should approach with caution. Skin that has recently been treated with strong chemical exfoliants or retinoids is often too fragile for safe treatment. Pregnant or breastfeeding individuals are also generally advised to wait.
Risks for Darker Skin Tones
If you have brown or Black skin, there’s a higher risk of post-inflammatory hyperpigmentation, where the treated areas become darker than surrounding skin. In some cases, the opposite happens, with lighter patches appearing. These color changes can sometimes be permanent, though they’re more commonly temporary. A prescription skin-lightening cream containing hydroquinone may help if blotchiness develops after healing. Scarring is also slightly more common in darker skin tones, though this is rare with microdermabrasion specifically (as opposed to the more aggressive dermabrasion procedure).
If you have a deeper skin tone, discuss these risks beforehand and consider starting with a less aggressive setting to see how your skin responds before increasing intensity.
