My Skincare Journey with SK-II and Sulwhasoo

Skincare’s been my obsession since my 20s, when stress dulled my face.

Chicago’s brutal winters left my skin dry, so I needed hydration and anti-aging magic.

SK-II, a Japanese icon, and Sulwhasoo, a Korean gem, stood out for their luxurious promises.

I tested SK-II’s Facial Treatment Essence and Skinpower Cream against Sulwhasoo’s First Care Activating Serum and Concentrated Ginseng Renewing Cream EX.

For six months, I used them on my normal-to-dry skin, tracking every glow-up.

Here’s what I learned about these skincare giants.

SK-II, born in 1980, is all about Pitera™, a yeast-derived ingredient for radiant skin.

Sulwhasoo, launched in 1966, uses ginseng and Korean herbal medicine for balanced, youthful skin.

Both target aging, but their approaches differ.

I’ll break down their hero products, share my tests, and list pros and cons to help you choose.
