Face Serum + Moisturizer

Light lotion like skin moisturizer. Theres no scent and good with sensitive skin.
I’ve noticed a light difference in aiding with glass like skin for fine lines around mouth and forehead.

LOVING the texture of this!!! I've been using for 2 weeks and my skin feels smoother, and my smile lines look less prominent. my foundation used to always cake around the mouth area but the moisturizer really helps with that problem. recommend 10/10 and will be repurchasing.

fantastic! Bought for my sister and I. we're both in our 50s and looking for something that will hold us in between botox and other in-clinic treatments. I've tried many medical grade serums, retinol, and other growth factors in the last few years but glad I added this into my routine! So far feeling my skin is bouncier, has great hydration throughout the day, and my lines look better than couple of weeks ago. This is noticeble in photos which is super impressive after ~3 weeks of consistent use!

This is my skin bare, no makeup! Ive had friends ask me what treatment Ive been doing lately, and the answer is nothing new other than this moisturizer! After about two months on the Longevity Protocol my tone is so much more even and there is this natural glow I never used to have. Hydrated, smooth, and my pores look smaller. One step morning and night and I am done.

I used to think I was already getting these permanent lines around my mouth, nasolabial folds, but it turns out my skin was very dehydrated and inflammed. This product is a godsend for me. It calmed down the inflammation and also properly gave my skin some much needed hydration, and the lines look so much softer. My skin tone has also improved so much, that I realy wear foundation anymore. I've been recommending this to everyone I know.

A New Staple in My Skincare Routine

I've tried a lot of moisturizers over the years, but Darkfin Labs has quickly become one of my favorites. The texture is lightweight yet deeply hydrating, sinking into skin without leaving any greasy residue behind.

What really stands out is the serum-like quality of the formula — after applying, my face feels incredibly smooth to the touch, almost like it's been polished. Within minutes, my skin takes on this soft, silky glow that makes it look genuinely nourished rather than just "moisturized." It's the kind of finish that makes you want to keep touching your own face (in a good way!).

I've noticed my skin looks plumper and more radiant with consistent use, and any rough or dry patches have smoothed right out. A little goes a long way, and it layers beautifully under makeup or sunscreen without pilling.

Beyond the product itself, I also had a great experience with customer support. I ran into an issue with my order, and Jason went above and beyond to sort it out quickly and courteously. It's always reassuring when a brand backs up a great product with great service.

If you're looking for a moisturizer that delivers that silky, lit-from-within look — and a company that actually takes care of its customers — I'd highly recommend giving Darkfin Labs a try.

This serum is amazing. 3 pumps is definitely enough to use for the face. It absorbs nicely and leaves my face feeling nourished. Will definitely buy more the future

I am only a week in but so far- I really like the product. It’s really nice to have so much in one product and I like that I can use it with tretonin- I am 51, so I am doing all I can (within reason) to keep my skin in good health. I am hoping I can keep my bathroom counter less cluttered- but plan to keep using the serum.

The packaging is defective. I went to use the product and was suprised that after pumping for a while nothing was coming out. Thats becasue there wasnt anything internally to connect to the outside pump to get the product out. Im having to dump it into my hand. Overall, not impressed.

I’m obsessed with the Longevity Protocol. Not only does it simplify my routine, my skin texture has improved significantly as well as its ability to heal. I’m an acne prone girlie and this helped clear up my skin and reduce the discoloration. I took a chance and did the subscription. About a week before my next one would ship, I let my husband try. Little did I know he kept using it—I ran out quicker and had to order more STAT and add an extra one for him. I don’t want to ever run out again!

So far, makes my skin look great!

It’s perfect—Don’t change a thing! I love this serum/moisturizer combo. I am six weeks in and I can tell it delivers on its promises of bouncier, more radiant skin with better texture and smaller pores. My skin feels balanced and I love the simplicity of this routine. 12/10 no notes!

Phenomenal product and will be a forever item in my routine!

I love the idea of reducing number of products, but I’ve been using less than a week, so too early to render judgment—-really hope it works!

Leaves my skin feeling moisturized and shiny. So far so good. I have been using it for the last month!

I'm so impressed by how my skin looks after around a month of daily use. My past main concerns were smile lines, and dehydrated forehead lines. The moisturizer has done a great job of easing them, and makes my skin feel bouncier, and firmer. I'm back for another bottle, this has been a total game changer.

Great! Convenient, haven’t seen super noticeable improvements in my skin but no breakouts. Skin looks great too. One thing is that the pump function on mine seems to malfunction a bit. I got it to work after many pumps, but sometimes a weird sound occurs.

So far so good on this product. Very expensive and hoping it works. So far I haven't seen any major results in 3 weeks of use. Will update after a few months

I’ve recently started using Longevity Protocol and my initial impression has been positive. The formula feels lightweight, absorbs well, and leaves my skin feeling hydrated without feeling greasy. I appreciate the combination of moisturizing and serum benefits in a single product, as well as the thoughtful ingredient profile. I’m looking forward to incorporating it into my daily routine and seeing the long-term results.

It feels great on my face and is working very nicely

This serum is lightweight on your skin allowing the skin to breathe and easy to apply. There is no scent and leaves skin feeling moisturized. The serums container is in a pretty sturdy and sizable bottle allowing for the product to pump out with ease and may last approximately 3+ months of usage if using day and night. It mixes well with other skin care products. Nice product and look forward to long-lasting glass like skin.

This is a very beautiful serum. makes my skin feel refreshed, and gives a healthy glow. 10.10

Game changer product—I have very sensitive skin prone to peeling, dryness. Also lots of freckles and sun spots. This product that’s really been a godsend for me. I also love how simple it is. Literally I wash my face, put on a few pumps, and bam I’m done no other complicated layers. I’m seeing a lot of texture improvement already and my smile lines are better.

I'm a new mom so balancing work, a baby, and other stuff has really stressed out my skin. I went from generally good skin (rarely ever needed makeup, no breakouts) in my 30s to looking exhausted and older almost overnight. I've tried a lot of other stuff but this is really amazing! I love how its not greasy AT ALL but still keeps my skin feeling nice and hydrated all day. Ive been noticing a real improvement in the lines around my eyes and forehead. My dark spots are looking brighter after a month of using this stuff. I bought another bottle for hubby to also try. Love seeing new brands innovate and create magic!

Guy here who travels a lot and is on planes 24/7, this is exactly what I needed. This is the only thing I use besides sunscreen and my skin has never looked better — smoother, glowy, and just great. I'm very into the sceince as well and their backstory is very impressive, as a biotech lab that started a skincare line. Im all for it and excited to see them make other products down the line.

Writing the detailed version since the short reviews didn't tell me what I wanted before buying. I'm 36, oily T-zone, dry cheeks, and easily broken out. The Longevity Protocol is one of the few things that respects both halves of my face: it hydrates the dry parts without making my forehead an oil slick, and I have not had a single congestion bump in six weeks. The finish is dewy but never greasy, it sits perfectly under sunscreen and makeup with zero pilling, and there's no fragrance to irritate me. Results-wise, my skin tone is more even and my pores look smaller, which I didn't even buy it for. It also collapsed my routine from five products to basically this and SPF, which is the real reason I'll keep buying it.

My dermatologist told me to simplify my routine and this was the perfect two-in-one swap. My barrier is happier.

It's fine. Hydrating and absorbs well and no irritation, but I'm not seeing the dramatic firming everyone mentions. Decent for the money, maybe.
