The areas on the skin where blemishes, cysts, lesions, etc. had occurred get acne scars. There are three varieties of scars according to dermatologists. The varieties are:
- Atrophic acne, which is generally shallow.
- Ice peak-shaped, which is narrow and deep.
Erythema or redness within can be found among people with light skin tone while hyper-pigmentation or darkening within scars can be found among people with dark skin tone.
Most people have the tendency to burst out blisters of acne on their face. The embarrassment that swollen blisters cause is understandable. However, bursting them out does not help for good. It leaves scar behind it. Oil, dirt, etc. clogs these scars, which then require continuous face wash and cleansing. However, picking and bursting of acne is not to be excessively regretted as scars are formed otherwise too. The formation of lesion or cyst exerts tremendous pressure on the epidermis of skin and consequently causes scars. The good part is that existing acne scars can be healed and the new ones can be avoided with the help of modern treatment.
Effects of various components on acne scars
- Sun – Exposition of scars to sun darkens them and slows down the process of healing. The UV rays of the sun are stimuli for melanocytes, which are cells that produce pigments. Thus, skin gets discolored. Application of sunscreen with physical blocker zinc oxide and Sun Protection Factor (SPF) of 115 or above before getting out is the best preventive step.
- Picking or Squeezing – Scars are means by which body repairs itself. They are made of collagen, which is protein fibre that is normally present in the second layer of skin. Inflammation causes loss of collagen, which causes scars to indent. Picking can cause further inflammation and so starts the cycle. Popping-out of pimples lets pus and consequently bacteria to reach deeper into the skin. In this way the situation gets worse.
- Vitamin E – Topical application of Vitamin E, unlike the common notion, hinders the healing of acne scars.
- Cortisone Creams – Red or swollen scars should be treated with commercially available cortisone cream to reduce inflammation. Lightening creams that are constituted of Arbutin, Kojic acid, Vitamin C, etc. are then required to lighten the hyper-pigmentation left by the acne scars. However, the indentations cannot be filled by any cosmetic product.
- Laser & Fillers – People may opt for laser treatment, if scars do not fade. Non-ablative laser of fractionated laser technology increases formation of new collagen that fill scars and gradually even skin. On the other side, ablative laser vaporize scars and let new, smooth skin replace them. Filler injections are also beneficial for the skin. However, fillers get absorbed by the skin gradually. Therefore, the procedure has to be repeated every few months.
