Aloe vera gel maybe one of the most popular acne scar treatments. While there's limited evidence the gel will remove or alleviate these scars, it has been demonstrated to assist wound healing and keep skin moist, which may prevent scarring. It also reduces scar tightness.
Lavender and tea tree oils may reduce inflammation and aid skin healing, minimising scarring. Scars are less likely to fade. Always dilute essential oils before applying to skin.
