Microdermabrasion Crystals: What Grit Size Should You Choose?

Microdermabrasion is a favorite at-home treatment for smoothing skin, fading dark spots, and boosting glow. But if you've ever shopped for crystals, you've likely seen numbers like 120 grit or 240 grit and wondered: what does that even mean? Grit size determines how aggressive the exfoliation is, and choosing the wrong one can lead to irritation or underwhelming results.

In this guide, we break down microdermabrasion grit sizes, explain the difference between face and body exfoliation, and help you pick the perfect crystal for your skin type and goals. Whether you're a beginner or a seasoned pro, understanding grit will transform your home dermabrasion routine.

What Does Grit Size Mean in Microdermabrasion?

Grit refers to the size of the abrasive particles in microdermabrasion crystals. The number indicates how many particles fit in a square inch; lower numbers mean larger, coarser particles, while higher numbers mean smaller, finer ones. For example, 120 grit crystals are relatively large and provide a deep, vigorous exfoliation, while 400 grit crystals are very fine and gentle.

When you use microdermabrasion crystals, they are sprayed onto the skin and then vacuumed away, along with dead skin cells. The grit size directly impacts how much skin is removed and how much friction you feel. Choosing the right grit is essential for achieving your desired results without over-exfoliating or damaging your skin barrier.

• Lower grit (e.g., 60-120) = coarser, more aggressive exfoliation
• Medium grit (e.g., 200-300) = balanced for most skin types
• Higher grit (e.g., 400+) = fine, gentle for sensitive areas

Face vs. Body: Which Grit Should You Use?

Your face has thinner, more delicate skin than your body, so it requires a finer grit. For facial microdermabrasion, we recommend starting with a higher grit, such as 240 or 300, to gently resurface without causing redness or micro-tears. If you're new to home dermabrasion, even a 400-grit crystal can be a safe starting point.

For the body, you can use a coarser grit to tackle thicker skin on areas like elbows, knees, and feet. A 120 grit crystal is ideal for body exfoliation because it effectively sloughs off rough patches and stimulates circulation. However, avoid using coarse grit on sensitive areas like the neck or chest.

• Face: 240-400 grit for gentle exfoliation
• Body: 120-200 grit for tougher skin
• Avoid coarse grit on thin or sensitive skin

How to Choose the Right Grit for Your Skin Type

Your skin type plays a huge role in determining the ideal grit size. If you have sensitive or easily irritated skin, always opt for a finer grit (300 or higher) and perform a patch test first. Normal to combination skin can handle medium grits like 200-240, while oily or thick skin may benefit from a coarser 120 grit, but only on the body.

It's also important to consider your skin concerns. For fine lines and dullness, a medium grit can help stimulate collagen. For hyperpigmentation or rough texture, a slightly coarser grit may be more effective, but always balance exfoliation with hydration. If you're using a chemical exfoliant like lactic acid, you may want to stick to a finer physical grit to avoid over-exfoliation.

• Sensitive skin: 300+ grit
• Normal/combination: 200-240 grit
• Oily/thick (body only): 120 grit

Tips for Safe Home Microdermabrasion

Even with the right grit, improper technique can cause harm. Always start with clean, dry skin and move the handpiece in gentle, upward strokes. Do not apply pressure; let the vacuum do the work. Limit treatments to once a week for beginners, and always follow up with a hydrating serum and moisturizer.

Remember to avoid active breakouts, sunburn, or open wounds. If you have a history of cold sores, microdermabrasion can trigger an outbreak, so consider taking precautions. And never use microdermabrasion on the same day as a chemical peel or retinol treatment.

• Always patch test a new grit on a small area first
• Use a gentle touch and let the device glide
• Moisturize immediately after treatment
