SCP-XXXX appears to be a male Caucasian humanoid,
"Appears" implies that it's not actually what it looks like. Is it not actually a humanoid?
Also, not sure if we have Caucasian "humanoids". Humans, sure, but humanoid just means "human-shaped" so it's kind of hard to attribute race to that.
measuring approximately one hundred sixty (160) CM
Write out, "160 cm".
in height and weighing approximately 68 kilograms. Subject is completely devoid of facial features,
Don't refer to an individual as a "subject" unless you've established the experimental protocol they're being subjected to. If there's no research design or observation ongoing, they're not a subject of anything and shouldn't be called such.
In this case, it'd be better to use "the entity" or "the individual" or just "SCP-XXXX".
including nose, eyes, mouth, and facial hair.
I feel like this is unnecessary, as the average reader will know what facial features are.
Despite lacking eyes, SCP-XXXX seems to posses a perfect sense of sight.
"Possess". Also, how did the Foundation confirm this? What kind of tests/empirical research supports this fact?
Keep in mind that as the author, you know the entire story, but the Foundation needs to have discovered what it knows about the SCP object through observation and experimentation. You'll need to convince your reader that someone with no prior knowledge whatsoever of the anomaly managed to somehow figure out (not magically know!) all the information you've got in the article.
SCP-XXXX is also capable of absorbing liquids, presumably for subsistence.
Sustenance. Most organisms are inclined to thrive, rather than just barely get by.
The method of which SCP-XXXX absorbs liquid is unknown, and it refuses to do this action if it is being observed.
Ohhh. Now I understand the containment procedures a little more (but not in particular, since the [REDACTED] substance could have been birthday cake for all I knew with the given context)
SCP-XXXX is incredibly hostile.
"Incredibly" feels like an exaggeration, but also kind of too casual for an official report. Besides, we've already got so many hostile SCPs that we've got a tag for it: http://www.scp-wiki.net/system:page-tags/tag/hostile
When SCP-XXXX gains sight of a living human,
"Gains sight" is a strange way to put it, especially since it doesn't have eyes.
it will attack that human,
Why only humans? Plenty of other animals have faces, and skin.
and attempt to remove all the flesh from its victim's face using SCP-XXXX's [DATA EXPUNGED].
This effectively removes the interesting parts and feels a bit like a cop-out, especially since we don't know anything about this thing's anatomy beyond "Caucasian human-shaped thing".
I recommend reading over this guide on interesting expungment for some tips on writing interesting expungment.
Victims of SCP-XXXX's usually die within moments of the attack from blood loss, shock, or both. There have been ██ cases of people surviving the attack after extensive health care, but the survivors are still very mutilated, and usually experience partial loss of vision and PTSD.
Nothing particularly new when it comes to standard humanoid monsters, I'm afraid.
Keep in mind that we get so many monsters in a given week that the ones that aren't straightforward kill-mutilate-wreck beasts tend to be more interesting. SCPs don't need to be dangerous to be successful.
SCP-XXXX will not attempt an attack if the human it sees has sufficient face protection, or has already been attacked before.
How did the Foundation figure out the second bit? Did they purposely send a victim of SCP-XXXX back to it?
If SCP-XXXX loses track of its victim it will give up after a short amount of time.
How long is "a short amount of time"?
Aside from its lack of face and hostile behavior, SCP-XXXX shows no other behavior anomalous for a humanoid.
This sentence isn't really necessary.
SCP-XXXX has shown signs of great intelligence, having an estimated IQ of 99.
Average human IQ is 100, so it's… actually below-average intelligence human-wise. IQ isn't really that great of a measure of intelligence anyway. It's only reliably a good measure of how good someone is at taking IQ tests. For further reading: http://www.scp-wiki.net/forum/t-970926/scp-s-and-iq-bonus-discussion-on-personality-tests-as-well
SCP-XXXX can also communicate through use of writing using a pen or pencil.
How did the Foundation figure this out? Did they just decide to give this incredibly hostile thing a pen… just because?
No interviews have been conducted with SCP-XXXX, but SCP-XXXX has written that it would be willing to interview a scientist.
This seems so disjointed from the rest of the article that it almost feels thrown-in as an afterthought.
