Firming Serum Booster with Progeline
Progeline is a highly sought-after peptide to improve the skin's elasticity, facial firmness, sagging jowls, and jawline by blocking progerin.
Restore facial firmness in sagging areas and the jawline by improving elasticity by inhibiting progerin with our Firming Serum Booster with Progeline.
Progeline is Trifluoroacetyl Tripeptide-2, used at 0.5 to 2% for the look of a firmer jawline, neck and jowl area. It is the peptide formulators reach for when the concern is slackness rather than lines.
This is a formulation ingredient, not a finished serum. Do not apply it undiluted.
What is in the bottle
INCI: Glycerin, Water (Aqua), Dextran, Trifluoroacetyl Tripeptide-2
Four ingredients. Glycerin is a humectant; dextran is a polysaccharide that gives the solution body and makes it blend cleanly. Both are carriers — the active is the tripeptide.
Vegan, paraben-free, fragrance-free, cruelty-free. 0.5 oz blue glass dropper bottle.
The science: Progeline and progerin
Progeline is a biomimetic peptide developed around progerin — a protein that accumulates in cells over time and is studied in connection with cellular ageing. The supplier's research programme is built on that relationship, which is why Progeline is grouped with the firming peptides rather than the line-focused ones.
In a topical formula, it is used for the appearance of firmer, better-defined contours along the jaw and neck.
The supplier's findings describe testing of the raw material. What you see depends on the concentration you use, your base, and how consistently you apply it.
How much to add
Recommended usage rate is 0.5 to 2%. Using our house rate of 9 drops per 1% per fluid ounce:

Where to use it
Progeline is used on the areas where skin looks slack rather than lined:
- Jawline and jowls — the most common reason people buy it
- Neck — works down from the jaw
- Around the eyes — for the look of a lifted lid and firmer under-eye
- Chest — an area that takes a lot of sun and gets forgotten
How to use it
- Choose a water-based serum, moisturiser or cream. Hyaluronic acid serum is the usual base — 18 drops into 1 oz gives you 2%.
- Cap and shake well, or stir it through if you are working into a cream.
- Refrigerate what you are not using.
- Apply morning and night to the jaw, neck and chest. Use upward strokes.
What to pair it with
For firmness, Progeline layers with Pepha-Tight, Relistase and Uplevity. All four are in the tightening group and work through different routes.
If your concern is expression lines rather than slackness, Argireline is the one you want instead.
Why buy it raw
Finished firming products naming Progeline rarely disclose how much is in them. Blend it yourself at a measured rate and you know — because you counted it in.

Firming Serum with Progeline
"I love this product and wouldn’t want to be without it. Thank you for making these special serums!"
Nice product
"I have used this for several years and mixed it with my essential oils and carrier oils. It complements them for very nice results. I have a little difficulty with settling, and would like larger size to sell to friends. Are there any issues with selling your product as an additive to mine?"
Desiring firmer skin
"I have purchased this product for the first time today. I have used other anti-aging products I like and was looking for a booster. I was happy to find DIY products with lots of information about the product, this helps me to be informed about what I am buying. I am 50, I’m taking collagen and have a regular natural skincare routine . I’m hoping this product will help with firming"

PROGELINE
"Unfortunately I cannot give a review or place an order (I have chosen a few other products) because I cannot get the lid off the bottle. The outer part unscrews and I cannot lift the dropper. So I have not yet tried it! Please advise."
Good Product
"Good product."
All three combined
"I call this the face wrinkle eliminator all combined they are powerful"
Love Progeline!
"This is my first time purchasing this product from you. I’ve purchased this particular peptide from another company but I’m so excited that I found your company where I can purchase all my peptides at a one-stop-shop instead of me shopping for all my peptides individually from all over the world. I also love to mix up my own formulations and add them to my favorite skincare creams. I purchased 8 separate peptides and I can’t wait to see how effective they are. I’m loving all of them so far! I will give you all an update soon! Thank you so much and oh, before I forget, the shipping was fast and packaged nicely!"
