I am a pale redhead who has developed rosacea in her early 30s. I've been into Asian beauty products for years but while researching brighteing products I came upon tone up creams. This is a product category I've never heard of in the US though it certainly has overlap in CC (color correcting). Essentially a tone up cream does the opposite of a fake tanning or bronzing product -- it makes your skin look a few shades brighter or lighter. I find this particularly helpful on days where rosacea makes my whole face a bit pink even if I'm not actually hot. The effect is subtle enough that it just makes my face look like it's natural shade. However, most of the time I actually use this cream at night because it contains so many beautifying ingredients that help to brighten and even out your skin tone in the long term. So if I'm having some redness before bed it's pretty common that I'll wake up and my face will already look brighter in the morning even though the cream itself may have rubbed off or absorbed in my sleep. I think it can also be used like a makeup primer but make sure to apply a thin layer so you won't look like a ghost. If your skin is very dry, you will want to combine this with another moisturizing product but if you have normal or slightly dry skin this is probably enough.
