Acne Scar Removal
Acne Scar Removal
Several medical treatments are available to help reduce acne scars. A dermatologist may recommend different procedures depending on a person's skin type and the extent of the scarring.
Medical treatments for acne scars include Laser procedure
Dermatologist can use a laser to remove the outer layer of your skin, contour areas of acne scars, or lighten redness around healed acne lesions. Various types of lasers are used, depending on whether the acne scar is raised or flat.
Atrophic acne scars appear as depressions in the skin.
The 3 main categories of atrophic scars are:
1. Ice pick scars: Deeper than they are wide, with a narrow opening.
2. Boxcar scars: Broad, rectangular depressions with steep, defined edges.
3. Rolling scars: Broad depressions that have rounded, sloping edges.
Types Of Laser Treatment For Acne Scar Removal
Lasers that are used for acne scar removal mainly fall into two categories:
· Ablative: These lasers can improve acne scars effectively and give impressive results. They remove the damaged tissue by vaporization or by melting it. The most commonly used ablative lasers are Erbium YAG and Carbon dioxide (CO2) lasers. These erode the scar surface and tighten the collagen fibers under your skin. Ablative lasers have a longer recovery time.
· Non-Ablative: Non-ablative lasers have a shorter recovery time, but the results are less impressive as compared to ablative lasers. These lasers do not remove any tissue from your skin but boost collagen development and make your skin tight. The most common non-ablative lasers used for acne scar treatment are the diode and NdYAG lasers.
Types of laser treatments used for acne scar removal.
Fractional Laser Treatment For Acne Scars
Fractional CO2 laser resurfacing uses a variety of micro beam sizes and densities to suit the needs of the patient. The fractional CO2 system can be used easily on other parts of the body (other than the face). This treatment can helps eliminate existing acne scars and also prevent new scar formation . https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3999431/
For textured acne scars, in particular (think: icepick, boxcar, and rolling scars), lasers are more effective than any topical treatment.
The Fraxel Dual laser utilizes the 1550 wavelength for acne scars. It is the first non-ablative laser and can be used with minimal downtime. The laser stimulates new collagen production by going deep into each pore to help rebuild your skin.
Intense Pulsed Light (IPL)
Intense Pulsed Light works on the principle of selective thermal damage in the target area. These devices emit high-intensity pulsed light that has a broad wavelength spectrum. This combination of wavelengths, pulse durations, and pulse intervals assists in treating a wide range of skin conditions.
Intense pulsed light is a non-invasive, non-ablative treatment that delivers high-intensity light into the deeper layers of the skin to improve fine lines and wrinkles, vascular lesions, redness, broken capillaries, and sun spots. The range and wavelength of the light emitted during the treatment can be adjusted to accommodate your specific skin needs and concerns such as fine lines and wrinkles, dark spots, visible capillaries, and redness
A Q-Switched (aka Q-Switched Nd-Yag Laser) Laser is used in various procedures: the laser is a beam of energy at a specific wavelength (1064nm) which is applied to the skin and is absorbed by coloured pigments such as freckles, sun spots, age spots, etc. in the skin. https://www.ncbi.nlm.nih.gov/pubmed/15545542
The power settings of the laser can be set at different levels and frequencies to accommodate your specific condition and expectations
This procedure gently resurfaces your skin and improves the skin texture by reducing acne scarring and wrinkles. In the process radio frequency (or electrical pulses) is used to smoothen your skin. Each pulse delivered to the skin activates the fibroblasts in the target area, which stimulate collagen regeneration .
· Acne marks – acne marks are caused by inflammation (the redness and pain) from pimples. The inflammation causes the skin to produce pigments. These pigments are cause of acne marks, which can be effectively removed with the laser.
· Pimples and acne – the laser energy can also kill P-acne, which is the bacteria that cause pimples and acne. At the same time, the laser energy also shrinks the oil glands in the skin and helps with oil control. Pimples and acne also tend to be less inflamed after laser treatments and this reduces the amount of acne marks after a breakout.
· Tattoo removal – tattoo inks are foreign pigments introduced into the body. Like natural skin pigmentations, the laser energy breaks down the tattoo ink and removes the tattoo.
