Acne Scars

Acne scars can be psychologically disturbing and everyone who has them wishes they get rid of these craters and pits on their face. At Skinfiniti, Dr Jaishree examines the types of scars and decided on a combination of treatments to reduce the scars by almost 80%. A single treatment modality is never enough. Peels, Dermaroller, fractional laser, subcision, cryotherapy and now RF microneedling are done as required to give you a smoother clearer scar free skin.

The Latest In The Treatment of Acne Scars is Radiofrequency Microneedling

What is Radiofrequency Microneedling?
The procedure involves penetration of insulated microneedles into the skin deep layer i.e.dermis to deliver radiofrequency pulse into the targeted tissue.This results in the body’s own production of collagen fibres,making skin firmer and healthier.
What does RF Microneedling Involve?
Topical numbing cream is applied to the area of treatment 1hour before the treatment to minimize any discomfort during procedure.Once the area is numbed,site is cleansed the with spirit,doctor will then apply the device to skin surface releasing the needles and delivering radiofrequency energy in shot bursts as the head is moved across the area to be treated.Three passess of RF microneedling is done with decreasing depth.
Immediately after the procedure,face is warm,red and swollen.If uncomfortable a cool pack is applied to the area.

What is Radiofrequency microneedling used for?
It is used for
1.Scar treatment such as deep acne scars,ice prick scars,atrophic scars,burns and operation scars tightening and brightening,facial rejuvenation,pore size reduction and stretch marks.

What are the benefits of RF microneedling?
1.Minimally invasive
2.Short procedure time and downtime
3.Lower risks such as postinflamatory hyperpigmentation and scarring

What is post treatment care?
Mild redness and swelling may occur few hours and upto 24hrs after treatment.Avoid Sun exposure for 7days.Avoid massage,procedures like waxing/facial/bleaching for 7 days.Avoid skin lightening creams for 3 days.
Moisturiser and sunscreen are highly recommended during recovery period.

Who should not do RF microneeedling?
Patients with skin infections,bleeding disorders,keloids, patients on anticoagulants & pregnant women .

How often do I need treatments?
The interval between RF microneedling is 4-6weeks.However 6-8 treatments is required depending on the condition of patients skin.

Are there any side effects?
Immediately after the treatment there may be some pinpoint bleeding and sometimes swelling.both are quickly resolved with cooling packs which minimize inflammation.
Redness is variable from patient to patient and usually settles in 24-48hrs.
Some patients may experience dryness for short time.

If acne are not treated on time or if one has the habit of picking at acne, one does develop scars which in turn may cause a psychological trauma to the person.

Acne scars may be in the form of :
1. Macules are small dark skin discolorations and are flat.
2. Depressed fibrotic scar & Ice-pick scars are large, depressed valleys on the surface of the skin. They are usually jagged.
3. Soft scars are gentle, scar-like depressions in the skin. They are usually small, and either circular or linear.
4. Raised scars are called hypertrophic scars.

Macules & pigmented scars can be treated with chemical peels or microdermabrasion.

Microdermabrasion is done for extremely superficial scars. The superficial layer of the skin is abraded with crystals of inert aluminum oxide which are ejected with force in a controlled manner. It needs to be repeated once in 3 weeks for about 6 sessions.

Chemical peels are done for superficial scars, pigmented scars & soft scars. After properly studying the skin type and its sensitivity, the doctor decides on the type of peeling agent and its concentration. The skin is first cleaned & the peeling agent is then applied gently onto the lesion or on the full face till the ‘end point’ is achieved. During the procedure, the patient might experience warmth or stinging sensation. The peel is repeated every fortnight for 6-8 sessions. The different type of peels used are : alpha hydroxy peel such as glycolic acid- derived from sugarcane; lactic acid derived from milk ; kojic acid derived from a Japanese mushroom; mandelic acid derived from apples ; salicylic acid , a beta hydroxyl acid derived from willow birch.

Microneedling with Dermaroller : It is a fairly newer treatment which involves breaking of the fibrotic bands with a rolling instrument. This causes collagen remodelling in the next 2-3 months. It should be repeated once in a month for 6-8 sessions. If you have rolling scars, depressed scars and do not have time for a surgery or if a laser treatment is expensive, this is an excellent treatment for you. The downtime is just 1-2 days.

Fractionated erbium yag laser (PIXEL laser) or Fractionated Co2 laser: The newest form of treatment for acne scarring is called fractional laser therapy. This type of treatment works at a deeper level & wounds the skin using microscopic pulses of light. Because fractional laser therapy doesn’t wound the top layer of tissue, healing time is shorter. It penetrates deep into the dermis, eliminating damaged cells and stimulating the growth of new collagen. Collagen is stimulated for up to 4 months and this new collagen regeneration lifts and supports the skin’s surface. The generation of the new skin cells in combination with collagen stimulation will dramatically improve the appearance of acne scars. Depending on the depth of the scars, some patients may require anywhere from 1 to 3 treatments for acne scar removal. It is a blessing for those seeking treatment for deeper scars.It also improves the skin tone & texture.

Surgical methods : For extremely deep scars, one may have to go for surgeries such as punch excision & grafting, dermabrasion or laser ablation. However, these procedures involve a lot of downtime. Secondly, one has to be extremely careful after dermabrasion or laser ablation since chances of post treatment pigmentation are very high if you are exposed to sunlight for upto 2 months post surgery.
