The best treatment for stretchmarks are combination therapy that stimulates the collagen in that area. Results are achieved when stretchmarks are still new and a pink/purple colour. Once they have turned white we can improve them but might never be able to remove them completely. A combination of laser treatments with skin needling will be the best option. With regards to the acne it is important to put her on a skin care range for acne and a zinc supplement for healing as well as a supplement that will reduce internal inflammation. It is important for her to not ‘pick’ at her skin. A diet where she cuts out inflammatory foods such as gluten, dairy and sugar will also assist in preventing acne.
