How to remove old scars with tips

Old scars can be improved by silicone gel, laser therapy, microneedle therapy, surgical resection, pressure therapy, etc. Scar formation is related to factors such as the depth of skin damage, healing process, and personal constitution.

1. Silicone gel

Silicone gel is applicable to the early stage of hypertrophic scar or keloid, and plays a role by keeping scar tissue moist and inhibiting excessive collagen proliferation. Common products include compound heparin sodium allantoin gel, asiaticoside cream ointment, etc. Apply thinly after daily skin cleansing and continue using for 3-6 months. The effect on old scars is limited, and it is recommended to cooperate with other treatments.

2. Laser therapy

Dot matrix laser or pulsed dye laser can improve uneven scars. Laser stimulates collagen remodeling and promotes epidermal regeneration, making scar color similar to surrounding skin. 3-5 treatments are required, with an interval of 4-8 weeks. Temporary redness and swelling may occur, and strict sun protection is required after surgery. Not suitable for active skin diseases or photosensitive individuals.

3. Micro needle therapy

Micro needles induce skin self repair through mechanical stimulation, promoting orderly arrangement of collagen. Suitable for superficial scars, treatment should be administered once a month, with 4-6 sessions being the complete course of treatment. Mild bleeding or scabbing may occur, avoid contact with water within 24 hours. Vitamin A acid products should be avoided before and after treatment, and caution should be used for individuals with scar constitution.

4. Surgical resection

For stubborn hypertrophic scars or contracted scars, scar resection combined with Z-shaped surgery can be used to improve. postoperative radiation therapy or drug injection should be combined to prevent recurrence. There is a risk of infection, hematoma, etc., and experienced doctors should be selected for operation. After surgery, it is necessary to use a tension reducer for 3-6 months and avoid vigorous exercise.

5. Pressure therapy

Customized elastic clothing or pressure pads suppress scar growth through continuous compression. Wear it for at least 23 hours a day and persist for 6-12 months. Suitable for large-area scars after burns, requiring regular adjustment of pressure intensity. May cause skin itching or damage, can be used in conjunction with moisturizers. During the growth period of children, it is necessary to frequently replace pressure devices.

Scar care should pay attention to avoiding repeated friction and exposure to sunlight, and keep the area clean and dry. During the healing period of fresh wounds, medical silicone patches can be used to prevent scar formation. Supplement vitamin C and high-quality protein appropriately in diet, and avoid spicy and stimulating foods. If scars experience pain, itching, or rapid enlargement, it is necessary to seek medical attention promptly to investigate the possibility of scar malignancy. All treatments must be carried out under the guidance of professional doctors, and do not attempt corrosive drugs or folk remedies on your own.
