Sebum-absorbing sheet mask for oily skin: CSSAE Sebum Clearing Mask
In short
CSSAE Sebum Clearing Mask is a sebum pack with a bio-cellulose sheet that pulls oil and pore debris out of the skin. With oily skin that had flared up from the wrong peeling gel — and a dermatologist's order to stop using peeling gels altogether — the writer applied CSSAE Sebum Clearing Mask for about an hour after showering, then soaked the used sheet in water to see the sebum it had drawn out. No sting, visible sebum, and makeup went on smoothly the next day, so it worked even on skin that had turned sensitive.

Why oily skin needed a sebum pack after a peeling gel ban
My skin worry!! I have oily skin, so in summer especially the oiliness ramps up, and sebum production goes with it — it drives me crazy.
Not long ago my skin totally flipped out on me. In 26 years I'd almost never had that happen, but once it flared up this time, my skin just kept acting up... I went to three different dermatology clinics, and it was finally sorted out at the last one.
The doctor there had a fair amount of experience, and the moment she looked at my skin she said, 'You used a peeling gel wrong, didn't you?' Yes... I'd been stressed about sebum and scrubbed hard with a peeling gel trying to get smooth skin, and apparently that was exactly the problem...!!
So I got the peeling gel ban, plus orders to wash with cold water and keep cleansing under 30 seconds. For about a week I could barely wear makeup or wash my face properly. Since then I've been managing sebum a bit differently — no more peeling gel, haha.
There's a method using sebum pack sheet masks like CSSAE Sebum Clearing Mask that absorb sebum, blackheads, and more :D
Just looking at the mask packaging, doesn't it seem like it'll pull out every bit of sebum and blackheads, haha?
What kind of sebum pack is the CSSAE Sebum Clearing Mask?
The CSSAE sebum-absorbing mask uses a bio-cellulose sheet that gently absorbs sebum and pore debris, helping refine skin texture and care for pores!! It's a 0.3mm ultra-thin bio-cellulose sheet that gives a refreshing scaling effect without any squeezing.
It's said to block the cause of daily recurring bad sebum production from the source. Quercetin is a representative flavonoid antioxidant found abundantly in onions, apples, berries, green tea, and more. It's one of the bioactive compounds plants produce to protect themselves from environmental stress, and this antioxidant — 20 times stronger than vitamin C and 5 times stronger than tocopherol — is said to suppress the enzyme that generates sebum inside pores! It doesn't just clear things out, it calms the root cause of oil production.
PDRN + COLLASOME-PEP. PDRN firms up the elasticity of the pore walls, while COLLASOME-PEP cares for the skin barrier, preventing moisture loss and reinforcing the barrier!! It tightens the pore openings shut, haha.
How to use the mask and how long to leave it on
The mask sheet is covered with a double-sided cover. You remove one side and apply it to the skin, then peel off the other cover, hehe.
Even the cover you peeled off has a ton of essence on it!
Shower off, then pop the mask on — feels so good. You just leave it until the sheet is completely dry, so I did other things for about 30–40 minutes!
Look at the amount of essence, haha. It's apparently been tested on sensitive skin and rated 0.00 on the irritation scale, meaning it's classified as non-irritating!
I left it on for about an hour, and the photo above is from around the 50-minute mark. It had absorbed so much that the sheet had gone clinging and transparent!
↓ Grossness warning, haha
Soaking the sheet in water: how much sebum came out
I'd heard that if you dunk the mask in water after peeling it off, you can see the absorbed sebum, so I tried it — wow, haha. I was shocked at how much came out with zero irritation. Since it works by dissolving rather than force, it's gentle on skin and worked perfectly for my sensitive skin right now 😌. Among sebum packs, CSSAE feels like the best.
Watching the sebum in the water and checking my skin afterward, it was completely smooth once the sebum was gone... and the next day my makeup sat perfectly. So good!!
It clears out sebum, instantly supplies moisture to the spot it cleared, and even tightens the pores — so clean and easy skincare is totally possible. Highly recommend CSSAE Sebum Clearing Mask (●ˇ∀ˇ●)
