If you're looking for something else to incorporate into your skin-care routine to help treat your acne, Neutrogena Visibly Clear Light Therapy Targeted Acne Spot Treatment (£30) might be a worthy investment. The blue light kills acne-causing bacteria while the red light helps reduce inflammation, which can make acne worse. When used in conjunction with a good skin-care routine, it can be beneficial to help target specific areas of concern. As always, when it comes to acne treatments — and any other skin condition — it's best to ask your GP or dermatologist before use.
