no , not necessarily.acne might be caused by lots of factors such as hormones, diet , sleep routine, stress level , weather, genes etc. while damaged skin barrier is when ur skin feels sensitive/dry/redness/burning sensation whenever u apply products on it . u aren’t supposed to feel that way as skincare doesn’t need to feel pain to works. how do u k when ur skin barrier is damaged?? when u start to concern abt it. if ur skin barrier is normal & fine, u wouldn’t even bother abt it 😉😉😉
