My Go-to Face Wash Now, Clean Feeling, NO Residue, Very Affordable
Size: 13.5 Fl Oz (Pack of 1)
I've tried many face wash, trust. And this is the best even for dudes with POC oily skin. I use mostly Korean beauty products. And only premium brands. Premium brand costly but much of the other cheaper products is marketing and waste of money and time. Eurecin Hydrating Face Wash is not expensive, commonly found brand name in drug stores and box stores BUT it has the best cleaning feeling you get for washing your face without harsh chemical ingredients. \ No residue feeling. Very light before, during, and after. I say light, even before, because in the bottle it looks and moves like water, not really gel-like. Slides like water on your fingers when applying...then on your face it feels light too with moderate soapiness when rubbed and cleansing face. After washing your face, you feel like nothing is on your face, not residue oils, no weird medicinal smell. Just the cleanest feeling. And I use it everyday yet it last decently long. It's my go-to cleaning face wash now.

gentle and effective cleanser but a bit drying
Size: 6.8 Fl Oz (Pack of 1)
Update: I added another star to the original rating because I am able to fix the problem of dry skin with a light layer of squalane oil right after washing with this cleanser. Since I utilized moisturizing oil in my routine I no longer have dry and tight skin after cleansing. This cleanser is still effective at removing my mineral sunscreen without breaking me out or cause any irritations. I will finish the bottle and then decide if I will repurchase. I only use a (large) pea size at a time so this will go a long way. Original review: I have combo skin. My cheeks are very dry while the T zone is very oily. I used Vanicream facial cleanser for years. They are a bit drying on my cheeks in winter time but otherwise perfectly fine. I do not like the shiny mica in it, and Eucerin's hydrating cleansing gel has hyaluronic acid so it's supposedly more hydrating. The reality is that Eucerin is no more hydrating than Vanicream and even when used in the middle of summer it's slighly drying on my dry cheeks. Aside from that, it's totally fungal acne safe (just like the Vanicream), very gentle, did not break me out, and has a very pleasant consistency. I will not buy it again given the disappointing hydration capability and higher price (than Vanicream). BTW, I do not wear make up so I cannot compare the two for cleansing abilities.
