Background
Coronaviruses (CoVs) are enveloped viruses with a positive sense RNA genome, that belong to the subfamily Coronavirinae within the family Coronaviridae, which is part of the Nidovirales order. The CoVs virion contains at least four structural proteins: spike (S), envelope (E), membrane (M) and nucleocapsid (N). Among them, the S protein plays an essential role in viral attachment, fusion, entry, and transmission. It comprises an N-terminal S1 subunit responsible for virus–receptor binding and a C-terminal S2 subunit responsible for virus–cell membrane fusion. S1 is further divided into an N-terminal domain (NTD) and a receptor-binding domain (RBD). During infection, CoV first binds the host cell through interaction between its S1-RBD and the cell membrane receptor, triggering conformational changes in the S2 subunit that result in virus fusion and entry into the target cell.

Screamo for Creamo! Update on Sage and Citrus and Cologne
Scent: Bourbon Oak, Size: 16 Fl Oz (Pack of 2)
So first off the product came exactly as depicted. The smell was good but not strong or offensive. It has a pleasing woodsy smell. The name says it all. The lather is not particularly big but that doesn’t define how clean you get. I think it cleaned me up very well with one caveat. My face is a little oily so I did purchase the Creamo face wash. The body wash really didn’t do the trick for my face which is somewhat oily. The bottle is reminiscent of the past and stylish. It overall is a great product.
I just bought the Sage and Citrus body wash. This is a great all season body wash with a more contemporary smell. It’s lighter than the Bourbon and Oak with, as stated, a citrus smell tempered with the earthy sage. Again it does not clean my oily face but I use the Creamo face wash and it does just fine. The rest of my body feels clean and the scent is light and not overpowering. Between both products I also use the shaving cream.
I enjoy the original scent. I tried the Bourbon scent with the Bourbon and Oak body wash and felt it was a little overpowering. On a good note I combined all this with the Bourbon and Oak cologne. The shaving cream last a long time and should be used sparingly. The value is in the amount you use. It’s far less than a cheaper shaving cream but offers superior protection and excellent moisturizing elements.
The cologne lasts all day and does not require but a single spray under both arms and a single spray on a wrist rubbed against the other. If you need an anti perspirant use one without a scent since this will conflict with the cologne. The value is definitely there as this cologne albeit simple in appearance has very delicate notes reminiscent of my more expensive cologne. I use Creed Vetiver for going out. This cologne has a very similar quality but is, of course, a different bouquet.
Overall the whole line of Creamo products seems to be well thought out and outshines many higher end products such as Clinique or Brickell which I have also used. It comes down to value and quality. That’s where it really wins. It’s made in California where I live!

Smooth Lather and a Balanced, Refreshing Scent
Scent: Sage & Citrus, Size: 32 Fl Oz (Pack of 1)
This body wash delivers a rich, consistent lather and a scent that’s both clean and uplifting. The sage adds a subtle herbal note while the citrus keeps it bright. It rinses off without residue and doesn’t dry out the skin. A well‑crafted formula that feels premium without the premium price tag.

Does this beat Anthony Invigorating wash in the long last smell
Scent: Seagrass & Driftwood, Size: 32 Fl Oz (Pack of 1)
Anthony Invigorating wash (check out my review of that) has a very strong pine scent to it and is a very long lasting smell. How does Cremo's products stand up to it!
I put deodorants, shampoos, and body washes through the same rigorous tests. I run 14+ miles 4-5 times a week, swim 20+ lengths (or laps) in a junior Olympic pool 3 days a week, use a Sauna 2-3 times in fifteen minute intervals 4 times a week, and use weights 4 days a week. All of these body washes and shampoos that I try out not only go up against Anthony's but also getting rid of that chlorine smell. I always will finish a product before reviewing it
I'll be honest here as always, the Blue Cedar and Cypress at first whiff smelled weird. I can't explain the 1st whiff smell though you have my warning. I thought this was going to be my least favorite of the 3 different Cremo products (bourbon and oak, seagrass and driftwood, and this one) that I received. I have the policy to use all the products up in their entirety, so you don't have to. After using it up, I actually like the smell of it. The cedar smell comes out once applied. I actually use this with Anthony Blue Sea Kelp Body (check out my review of that). This goes great with it.
So on my buy, borrow, or bury review rating system, this is a buy. The issue I have with it, is that Cremo products don't seem to be that moisturizing their smells are good and lasting. This beats the off the chlorine smell of the pool and works great in combination with Anthony's. Try it out, just get past that initial smell, you won't be disappointed.
Now for Cremo's seagrass and driftwood. The First smell test of it is very pleasant. It's once you've put it on does that wood smell really come out. The smell is good and does last long though the issue I have that it is not moisturizing. This goes great with Anthony's other 2 products that I have viewed (please check those out). So on my buy, borrow, or bury rating scale, this is a buy. If they could make their products more moisturizing it would be fantastic.
I'll be back here to review the Bourbon and Oak, I have not finished it yet though it's probably going to be my favorite of all the 3 Cremo products I've tried out.
Please check out all of my other reviews!

Great buy!
Scent: Palo Santo, Size: 16 Fl Oz (Pack of 2)
This is my favorite brand and the lather is second to none! The smell is amazing and the quality is worth the extra price. It leaves my skin feeling moisturized and soft.

FINALLY. THIS IS ACTUALLY WHAT YOU WANT.
Scent: Seagrass & Driftwood, Size: 32 Fl Oz (Pack of 1)
I’ve tried all of the soaps. All of them. Molten brown sucks, 18.21 sucks, Blackwood sucks, and brickell sucks.
All I wanted is a premium soap that doesn’t suck. All I wanted is to feel good and smell good. I work in kitchens, so I’m not some desk monkey needing to wash off the stale air, I have to actually clean myself.
I don’t even know how these soaps stay in business, you might as well be using Irish spring and save the money. Nothing moisturizes, I’m always left with dry skin, or the smell lasts all of 6 minutes.
Until now.
This stuff is actually the luxury brand I’m swearing by. It lasts on my skin, it lathers well, it cleans well, and it doesn’t give me itchy skin just to smell nice after a shower.
Also, it doesn’t cost $36 per bottle like molten brown does for 2 teaspoons of soap with gold flakes in it that smells great for 6 minutes. It’s cheaper, and you get more.
