@skincarewshannon: Mixing vitamin C & retinol was NOT a good idea for my sensitive skin 🚫 Both are potent actives and that caused irritation and redness I’ve switched to alternating days & using them at different times (vitamin C in the AM, retinol at night) and I’ve found I can use them that way! #skincare #SkinCare101 #sensitiveskin #fypシ
