Erbium Glass Laser Vs CO2 Laser: Which is better?

With each passing year, as age begins to catch up, it is perfectly normal to begin taking an interest in skin rejuvenation and skin resurfacing treatment options. Laser resurfacing technologies represent an exciting development to improve tone, texture and pigmentation of the skin. Of these, CO2 fractional laser and erbium glass laser are both commonly used for skin rejuvenation and resurfacing.

Although both of these ablative laser-based treatments are effective in resolving issues pertaining to skin textures, they differ from each other in some aspects including treatment mechanism, depth of treatment, and properties.

In this article, we will discuss the differences between the fractional Erbium laser and the CO2 laser as well as its effectiveness on different skin conditions.

Ablative Laser Resurfacing

Although erbium glass laser and CO2 laser are both classified as ablative lasers, they have different properties. But before we dive into their differences, let's first understand what ablative lasers are.

Ablative laser skin resurfacing involves the selective thermolysis of the epidermal and superficial dermal layers of the skin by targeting them with light energy, leading to better skin quality and tone. During the procedure, water in the skin cells absorb light energy from the laser emitting thermal energy, which destroys the surrounding tissue.

Ablative lasers vaporize tissue and therefore are more aggressive compared with the gentler non-ablative lasers that leave the skin intact. Although ablative lasers result in far more downtime and a lengthier recovery process, they remain the lasers that produce the most dramatic skin resurfacing outcomes. Non-ablative lasers are free of the side effects of ablative lasers and leaves the epidermis intact while producing rejuvenating skin effects. By comparison, the treatments are gentle and requite less downtime, but produce a more moderate response.

Erbium glass Laser and CO2 Laser: What's the Difference?

CO2 laser was once a major advancement in the area of facial skin resurfacing and has been used with great success for the treatment of wrinkles, photoaging, scarring as well as pigmentation. However, problems with prolonged healing, prolonged redness, risks of hyperpigmentation and hypopigmentation has led to the development of the erbium glass laser.

Additionally, the higher incidence of post inflammatory hyperpigmentation following a CO2 laser treatment in darker skin types is a major disadvantage of the CO2 laser over the erbium glass laser.

When laser energy interacts with tissue, there are four possible outcomes: absorption, scatter, reflection, and transmission. The amount of each depends to a large part on the wavelength of the laser energy and chromophore of the tissue.
