Overview
What is microdermabrasion?
Microdermabrasion is a non-invasive skin resurfacing treatment designed to exfoliate and rejuvenate the skin. It works by using a handheld device to remove the outermost layer of dead skin cells, revealing fresher, smoother skin underneath.
This process helps to:
- Improve skin tone, texture, and clarity
- Reduce the appearance of fine lines, acne scars, pigmentation, and dullness
There are two main types of microdermabrasion:
- Crystal-based — uses aluminium oxide crystals to exfoliate
- Diamond tip — uses a diamond-coated wand to abrade the skin
Both are popular in beauty salons, skin clinics, and increasingly, home-use devices.
Frequency
How often should you use a microdermabrasion machine?
Frequency depends on your skin type and treatment goals:
- Mild rejuvenation or maintenance: every 4 weeks
- Targeting scars or pigmentation: every 2 weeks for a short series
Overuse can lead to irritation or sensitivity. It's best to follow professional guidance. Home users should use gentler settings and longer intervals between treatments unless advised otherwise by a licensed skincare specialist.
Ingredients
What role do aluminium oxide crystals play in microdermabrasion?
Aluminium oxide crystals are the primary exfoliating agents in crystal microdermabrasion systems. These fine, inert crystals are blasted onto the skin and vacuumed away with dead skin cells and debris.
Their key benefits include:
- Controlled and effective abrasion
- Stimulated blood flow and lymphatic drainage
- Unclogging pores and enhancing skin cell turnover
They're also preferred for their hardness, sterility, and non-reactive nature — making them safe for most skin types when used correctly.
Comparison
Is crystal microdermabrasion better than diamond tip?
Both methods are effective, but each has unique advantages:
| Feature |
Crystal microdermabrasion |
Diamond tip microdermabrasion |
| Exfoliation method |
Aluminium oxide crystals |
Diamond-coated abrasive tip |
| Best for |
Oily or textured skin types |
Sensitive or thin skin |
| Precision |
Finer, deeper exfoliation |
More controlled and consistent |
| Clean-up |
Requires vacuum and crystal disposal |
No residual particles |
Crystal microdermabrasion may offer slightly deeper exfoliation, ideal for congested or thicker skin types. Diamond tip devices are often cleaner, better for delicate areas like under eyes or around lips, and preferred for those with sensitivity.
