zone 01 / forehead · lines & sun
Updated September 10, 2026 · 5 min read
The forehead is where lines show up first, and the boring truth is that sunscreen does more for that than any serum. The reason people skip it is texture: heavy, white, greasy by noon. Korean sunscreens got popular on TikTok because they fixed exactly that. Here are the two everyone compares, and a night step for when the skin looks dull.

Both are SPF50+ PA++++ chemical (organic-filter) sunscreens, which is why they feel light. If you have very reactive skin that stings with chemical filters, neither is your pick; look for a mineral one instead.
Most people use half of what's needed. The amount is about two finger-lengths of product for face and neck, or a quarter teaspoon. Put it on as the last step of your morning routine, wait a couple of minutes before makeup. If you're outside for more than two hours, reapply; a sunscreen stick or a spray over makeup is fine for that.
A sunscreen you wear at 60% of the dose every single day beats a "better" one you wear twice a week. That's the whole argument for these two.
This one isn't sun care. It's the product people pair with sunscreen for the forehead because it targets the other half of the problem: dull, dehydrated skin that makes lines look deeper. It's a peel-off film you sleep in. Apply a thin, even layer over clean skin at night, avoiding eyebrows and hairline, let it set, sleep, and peel it off in the morning from the edges. Twice a week is plenty. Skip it on nights you use retinol or acids.
If you sit near a window, yes. UVA comes through glass, and UVA is the aging one.
Both are formulated for the face; go close but not on the lid. If your eyes sting, that's the chemical filters, and the fix is a mineral sunscreen for that area.
Beauty of Joseon, for most people. It grips makeup better. SKIN1004 works if you wear little or nothing on top.
