The Saranghae 5 step system is amazing. I have acne prone sensitive rosacea aging skin and nothing has really helped, except for saranghae. i have been using their skincare for over 10 years!!! i have tried shesheido , clinique, clarins, la roche posay, lancôme, paula’s choice, etc. If my acne is treated, it would leave my skin super dry and aging fast! some lotions were too greasy and made me break out more, in addition to increased redness. I just have crazy difficult skin! Saranghae has been a lifesaver. It calms my redness down and moisturizes my face at same time? its Magic!! Please don’t ever stop selling this particular set! I wouldn’t know where to buy replacement.
