Seaweed mask is suitable for any skin type. Dry can replenish water, oily can adjust the balance of skin oil secretion. But also has the effects of hydrating, whitening, diminishing inflammation and removing bean lines.
Adding milk can whiten skin, but the hydrating effect is not as obvious as adding water.
I use water a day and milk a day, which is also very cost-effective. I can use a pack for nearly twenty days. And it is very cheap.
Try it, too. You'll like it.
