MEASURED. NOT PROMISED.
YOUR PORES AREN’T THE PROBLEM. YOUR SKINCARE IS.
Men’s skin produces roughly twice the oil — and oil stretches pores open. This is the regimen built around the serum clinically shown to reduce the appearance of pores.

The problem
WHY YOUR PORES SHOW MORE
Oil fills each pore, stretches the wall, and props it open. Men produce about twice as much of it. More oil, bigger-looking pores. Simple math.
Most skincare ignores this. Products built for less oily skin either strip you dry, which makes pore edges sharper and easier to see, or load on grease, which adds to the stretch. Either way, you lose.
The fix isn’t harsher product. It’s the right one.
The four causes
FOUR THINGS MAKE PORES LOOK BIGGER
01
OIL & BUILDUP
Excess oil and dead skin fill the follicle and stretch it open. The single biggest driver — and men produce about double the oil.
→ STEP 1 · THE CLEAN SLATE
02
COLLAGEN LOSS
Every pore is held taut by a ring of collagen. From your mid-20s on, that scaffold weakens, and pores stretch and sag.
→ STEP 2 · THE GREAT
03
DEHYDRATION
Dry skin makes pore edges sharper and more visible. Plump, hydrated skin presses them narrower.
→ STEP 3 · THE HYDRO LAYER
04
SUN DAMAGE
UV breaks down the same collagen that keeps pores tight. The most preventable cause on this list.
→ STEP 4 · THE FACE SPF
There’s a fifth factor: genetics. That one sets your baseline. The other four are workable.
The mechanism
YOU CAN’T SCRUB A PORE SMALLER
Scrubbing, stripping, and drying your skin out all backfire. Tight, dehydrated skin puts pores on display. What actually changes how pores read:
HOURS–DAYS
PLUMP
Hydration draws water into the skin around each pore. Plump skin presses the opening narrower and blurs its edge.
DAYS–WEEKS
CLEAR
Less oil and buildup inside the follicle means less pressure holding it open.
WEEKS
FIRM
Collagen support keeps the wall taut, so pores look tighter as skin firms.
Pores don’t shrink. They stop announcing themselves.
The routine
BUILT FOR THE PART OF YOUR DAY YOU ACTUALLY KEEP
The pore regimen is meant to live where you use it: on the sink, after the shower, before the day gets moving. Lightweight steps, no greasy finish, no bathroom science project.
The clinical work matters. So does making it easy enough to repeat.
The evidence
WE MEASURED IT
Most brands ask men if their pores look smaller. We did that too — then we measured with imaging instruments.
The Great · 45-day clinical study · Antera 3D imaging1
80% of men agreed pores appear minimized after 4 weeks. 73% said so on first use.2
The Hydro Layer · consumer perception study
Two products. Three studies. Same direction.
THE PORE REGIMEN
Four steps. Each one targets a cause.
01 CLEANSE
THE CLEAN SLATE
Washes out the oil and buildup — the biggest driver of visible pores. PHA and sea silt clear without stripping.
02 TREAT
THE GREAT
The proof-carrier. Clinically shown to reduce the appearance of pores: −26% pore index in 45 days. Re-engineered hyaluronic acid, collagen amino acids, niacinamide.1
03 SEAL
THE HYDRO LAYER
Locks in water so skin stays plump and pore edges stay blurred. 80% of men agreed pores appear minimized. Hyaluronic + polyglutamic acid, ceramides, peptides.2
04 DEFEND
THE FACE SPF
Daily UV defense against the most preventable cause of visible pores. Lightweight, no white cast, won’t add grease.
MEN ON THE REGIMEN
"I've been using this product daily and am so happy with the results. My skin is noticeable improved and I love that it doesn't feel too heavy/oily or clog my pores. Super excited to keep using it!"
Rated 5 out of 5 stars Nick H. · The Great
"I'm 60 years old and recently started using The Great. It absorbs quickly, doesn't leave a greasy feel, and makes my skin look a little smoother and firmer. I've noticed fewer fine lines and a healthy glow. I've even gotten several compliments on my skin, which hasn't ever happened before."
Rated 5 out of 5 stars Brad C. · The Great
"The hydro layer puts in a lot of work but after I rub it into my skin I don't even feel it there because it's so lightweight. The claims about being "non-greasy" are also very accurate. I can also tell that my pores are not as noticeable as they used to be."
Rated 5 out of 5 stars Graham · The Hydro Layer
"Really cleans the skin. Helps with clogged pores and after a month of use the pores seem smaller"
Rated 5 out of 5 stars Kurt F. · The Clean Slate
"This is a really light cleanser where I don't feel dried out or that I have a soapy film after washing it off. I've noticed I haven't had as many clogged pores while using it and it works great with my beard."
Rated 5 out of 5 stars Scott H. · The Clean Slate
"Perfect mix of face skin cream and suntan lotion. Not oily, doesn't cause breakouts, moisturizes skin, and most importantly I never burned on my face all summer being in the sun all day. Low key this is possibly best product from Caldera and I use the full regimen."
Rated 5 out of 5 stars Nic S. · The Face SPF

FAQ
How fast will I see a difference?
Hydration effects read quickly — in the Hydro Layer study, 73% of men said pores appeared minimized on first use. The measured changes take longer: the −26% pore index result came at day 45 of twice-daily use. Give it the full 45 days.
Do pores actually shrink?
No — and anyone who says otherwise is selling you something. Pore size is set by genetics, oil, collagen, and sun exposure. What changes is how visible they are: hydrated, clearer, firmer skin makes pores read noticeably smaller. That’s what we measured.
How does the subscription work?
Your regimen ships on your schedule at the subscriber price. Pause, skip, or cancel anytime.
