1. Chemical Peels: A chemical solution is applied to the skin to exfoliate the top layers and promote the growth of new, smoother skin. Types of peels used include Light (superficial), medium, and deep peels. It helps to surface-level scars and improving overall skin texture. Multiple sessions may be needed for better results. Chemical Peels like TCA peels, Glycolic acid, Jessner’s solution, etc, are used. They increase the skin cell turnover and increase collagen production. Used mainly for superficial scars. TCA CROSS: TCA CROSS stands for chemical reconstruction of skin scars. There is a coagulation of skin proteins with TCA, which helps in skin resurfacing.  It is mostly used for treating ice-pick scars.
2. Laser Therapy: Laser treatment procedure done by using focused light to remove and remodel the damaged skin and stimulate collagen production. Lasers used for treating acne scars are Fractional lasers like CO2 laser, and Erbium laser. These treatments are effective for atrophic scars. Multiple sessions are often required for best results. They help in resurfacing of scar to the skin surface. Suggested laser treatment is decided based on type of acne scar and the available downtime and customer preferences.
3. Microneedling: Microneedling treatment involves using fine needles to create micro-injuries in the skin, stimulating collagen production and helps in skin repair.  Improves the skin texture, reduces the appearance of scars, and enhances absorption of topical treatments. Recovery time is typically 1-2 days of redness and minor swelling. In Microneedling — Sterile derma-roller is used, which comprises of multiple, fine, sharp, thin needles which puncture the skin. There is development of micro injury which initiate the healing process and increases collagen production. 
4. Subcision: A minor surgical procedure that involves inserting a needle under the skin to break up fibrous bands and adhesions removing the adhesions which attach skin to underlying scar. Particularly effective for rolling scars. Often combined with other treatments like fillers or laser therapy for enhanced results. Recovery time is typically a few days of bruising and swelling. 
5. Radiofrequency (RF) Treatments: Usage of radiofrequency energy to heat the deeper layers of the skin, which causes control damage, and which increases collagen and elastin production in the skin. It helps in resurfacing of acne scars and skin tightening. Types of RF Treatments include Microneedling RF, Fractional RF.  
6. MNRF Treatment:  It has a dual advantage. i.e., works for the reduction of acne scars and it also causes an increase in collagen to tighten the skin. It is commonly done for ice-pick scars and boxcar scars.  Effective for both texture improvement and reducing pigmentation. Recovery time typically 1-3 days of redness with minor swelling.
7. Fractional Lasers: Fractional lasers like Co2 laser and Erbium YaG laser, target the deeper layers of the skin to cause increases heat with control damage to surrounding tissues. It helps in increase of collagen and elastin production. It also helps in resurfacing of acne scars and skin tightening like the Radiofrequency devices. More commonly done for box car scars and rolling scars. Post procedure, there will be redness and warmth of the surface. Recovery time can vary from 5-10 days depending on the laser used and the depth.
8. Dermal Fillers: Dermal fillers are injectable substances that fill in depressed scars and provide immediate improvement. Dermal fillers used include Hyaluronic acid fillers, collagen stimulators etc. Thought results are immediate but temporary, lasting from several months to over a year, depending on the fillers used. Mainly used for atrophic deeper scars like box car scars and rolling scars. 
9. Punch Excision and Elevation: Surgical techniques to treat deep ice pick and boxcar scars. Punch excision removes the scar, and the wound is closed with sutures, while punch elevation lifts the base of the scar to the level of the surrounding skin. Highly effective for specific types of deep scars. Recovery involves a short period of redness and swelling.
10.  Cryotherapy: Cryotherapy involves freezing the skin with liquid nitrogen to treat raised scars. Suitable for treating hypertrophic and keloid scars. Recovery time is a few days to a week, with possible blistering and peeling.
11.   Intralesional steroids: Done for hypertrophic, keloidal and papular acne scars. The steroid will helps in softening the collagen bundles, thereby with multiple sessions improving the softness and decreasing the depth of the acne scar.
