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.

The positives are (1) I love the minimal and intentional packaging, and (2) I love the feel of the product on my skin. The negatives are (1) the product smells like damp cardboard, and (2) the cannister would benefit from a light knurl texture to increase gripping when hands are damp (like after showering). Overall, I'm unsure if The L01 protocol is working; I've been using it twice a day, everyday for two weeks and I haven't noticed a difference in the tone or texture of my skin. I doubt I'm the target audience as I'm already an avid user of moisturizer and toner and do my best to protect my skin from excess sun exposure. I'll keep using it to support Anna and her efforts! Looking forward to the next set of products!

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.

I like layering thi sunder sunscreen and makeup. Helps it go on smoother.

Looks gorgeous on my vanity and the formula delivers. Silky, absorbs in seconds, skin feels soft all day.

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 read every ingredient list and this one actually made sense to me. Feels luxurious, no fragrance overload, and my skin looks brighter in the morning.

One step, morning and night, and I'm done. My skin feels plump and hydrated all day and my makeup sits so much better. Three weeks in and I'm not going back.

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.

I started using this recently and wow! I'm a fan. Its made my daily routine soo much easier.

Great hydration and a nice texture. On very dry winter days I add a little extra moisturizer on top, but otherwise it's all I need.

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.

One month in and I'm happy. Skin feels softer and looks brighter. Docking one star only because shipping took a bit longer than expected.

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!

Since it's an all-in-one, it's the only skincare I pack now. Skin stays happy even on long flights.

I'm 52 and have tried everything. This is the first product where I can see a real difference in how firm and bouncy my skin looks. Simple routine, great results.

it pairs well with my other retinol product, and my skin feels good after (no irritation)

I live in Denver and my skin is always dry. This keeps me hydrated well into the evening. Huge win.

I have rosacea-prone skin and was nervous, but no redness or stinging at all. It feels calming and comfortable.

So far, makes my skin look great!

Friends keep asking if I've been on vacation. It's this. My skin just looks lit from within.

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!

I have combination skin and most moisturizers break me out or leave me shiny. This one just leaves a soft glow. Obsessed.

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