Fractional lasers are divided into ablative fractional laser treatment and non ablative fractional laser skin resurfacing. What is the difference between the two? People who know medical beauty lasers should have heard of ablative and non-ablative fractional lasers, but they may not know much. What's the difference? How to choose?

What is ablative fractional laser?

Ablative fractional laser is a type of laser that emits a laser beam. The laser beam can instantly stimulate the skin tissue of the human body, promote the reorganization and reconstruction of collagen, initiate tissue repair and the growth of collagen fibers. Skin elasticity gradually regains its youthful, healthy radiance.

Fractional laser stimulates the activity of cells in the skin to treat acne pits, acne marks, acne scars and wrinkles, small wrinkles, large pores and other skin problems.

The difference between ablative fractional laser and non-ablative fractional laser

The most essential difference between the two is the formation of different skin lesions.

①Ablative fractional laser: Use the laser beam to exfoliate the bad skin and let the new skin grow, just like changing a layer of skin.

Fractional peeling laser is very effective for the treatment of pores, wrinkles and scars, but the healing time is long (there will be slight redness and swelling, and the scabbing time is about 7 days), and the pigmentation rate is high (about 5%), especially for People with darker skin are at higher risk of developing hyperpigmentation.

②Non-ablative fractional laser: just like the literal meaning, it is non ablative fractional laser skin resurfacing. Since the laser has no wounds, the operation time is short and the treatment process is simple. The principle of this kind of laser is the same as that of the fractional laser. The laser beam is generated by the laser to repair the necrotic tissue and promote the generation of new tissue.

Increase the collagen and elastic fibers of the skin to restore the "baby muscle" and restore the skin to a youthful state, so as to achieve the purpose required by beauty seekers. Although the skin will not fall off, the photothermal effect penetrates through the epidermis and penetrates into the dermis, which can still make our skin delicate and firm.

Advantages and disadvantages of ablative and non-ablative fractional lasers

Both treatments have advantages and disadvantages. From the perspective of treatment effect, the effect of ablative fractional laser treatment is maintained for a long time (research shows that the long-term effect of ablation fractional laser treatment is significantly better than the short-term effect), but its disadvantage is that the recovery period is longer and adverse reactions are prone to occur. Of course, with the advancement of laser technology, the safety and clinical application value of ablative fractional laser treatment are also gradually improving.

The non ablative fractional laser skin resurfacing method has the advantages of less stimulation and no side effects during treatment, so beauty seekers prefer to choose it. However, it has been observed that the treatment effect is not as good as the peeling method. For some special skin problems, it is better to choose the peeling fractional laser.

How to choose between ablative fractional laser and non-ablative fractional laser?

In fact, choose both according to the beauty seeker's own physical condition and skin condition. When choosing which laser treatment technique to use, the following factors should be considered:

1. Types and symptoms of skin lesions.

2. The patient's age, personal wishes, and expected results (the operator needs to explain to the patient the differences, adverse reactions and curative effects of various treatment methods).

3. It is best to combine multiple types of lasers or pulsed light with other treatment methods to achieve the best treatment effect.

What should be paid attention to in CO2 fractional laser skin resurfacing

1. Anti-inflammatory ointment (such as erythromycin ointment, chlortetracycline ointment, etc.) should be applied to the treatment site to prevent infection and inflammation of the treatment site; however, be careful not to apply too many times, otherwise it may cause scab formation and scarring.

2. After the CO2 fractional laser treatment is completed, do not touch the treatment area with water, and do not wear makeup or massage the treatment area in the initial stage.

3. Strenuous exercise should not be performed during the recovery period after laser treatment to avoid complications such as infection in the treatment area caused by sweating.

4. The scab on the treated area will fall off on its own within a week or so. Don't be tempted to pick it up with your hands, as this will easily cause scars and darkening of the skin.

5. Because everyone's skin condition is different, some people will have pigmentation after treatment and some will not. Under normal circumstances, these pigments will slowly fade in one or two months, and some people may take up to half a year.

Fractional laser skin resurfacing technology must go to a regular medical institution to choose a professional doctor. The treatment time is short, and life goes on as usual after treatment. In addition, the effect of fractional laser in moisturizing, wrinkle removal and whitening is also more advantageous than other medical beauty projects.
