I was experiencing a sudden rush of acne all over my face and it made me so uncomfortable. I went ahead to search for the product that was gentle and effective. Fortunately, I stumbled upon Seoul 1988 which had retinal liposome and black ginseng which absorbs deeper into the skin tackling deep rooted issues and help with skin elasticity. This product minimized my smile lines,hyperpigmentation and cleared my acne. Over a period of 2 weeks, I saw great improvement on my acne and face texture in general. I will definitely recommend this product. Best to use with your night routine, for a beginner incorporate it 3 times a week and gradually move to everyday nighttime use.
