Hi thank you for your question.
Consumption of collagen has not been shown to be beneficial for acne scar treatment. Acne scars are caused by improper healing after damage to the skin caused by inflammation.
This damage can cause raised (hypertrophic) or depressed / atrophic scars. Atrophic scars are the most commonly seen in patients seeking Acne scar treatment and can involve multiple procedures each with its different strengths and benefits. However, the underlying principle is collagen remodeling to reduce/improve scar appearance.
Please consult a doctor who can best advice you on the proper treatment of your acne scars!
