I had the same confusion as you, but Professor Wang Zhenjun who came to Mei 'an told me some tips: 1. Massage method: Massage the scar with the palm of your hand for 5- 10 minutes three times a day. This method has the best effect on newly scabbed wounds, but it is weak on old scars. 2. Ginger Slicing Method After slicing ginger, gently rubbing the scar can inhibit the granulation tissue from continuing to grow. 3. vitamin e daubing method vitamin e can penetrate into the skin to play its moisturizing role, and at the same time vitamin e can maintain skin elasticity. But you may not be familiar with the scar-removing effect of vitamin E. Puncture the vitamin E capsule with acupuncture, apply the liquid inside to the scar and gently massage for 5- 10 minutes twice a day. Persistence will have a better effect. 4. Vitamin C daubing method Vitamin C has whitening effect. Apply vitamin C to the dark scar to make the scar white, which is consistent with the surrounding healthy skin. 5. Lavender essential oil daubing method The beauty effect of lavender is always amazing, and the effect of lavender essential oil on lightening scars is also widely recognized. However, lavender essential oil has no obvious effect on new scars and old scars over 8 years old, but it has better effect on scars of 1 to 2 years old. In addition, the use of essential oils should always be especially careful. When applying essential oil to scars, don't bless skin without scars.
