Is this a finished serum I apply directly to my skin, or do I add it to another product?

This is a concentrated serum booster not a finished product for direct application. Add 2–5% to any formulation: hyaluronic acid base, lightweight moisturizer, or a custom blend. Mix thoroughly before applying. One 0.5 oz bottle yields 300+ drops.

What is the Progeline FF? What concentration do I use, and what does it visibly target on the skin? biomimetic

Progeline FF (Trifluoroacetyl Tripeptide-2) is an amino acid complex formulated to visibly improve the appearance of skin firmness and elasticity along the jawline, chin, and neck. Use at 2–5% for visible contoured jawline and neck firming results.

Can I mix this with other peptides like Matrixyl or Argireline, and where does it go in my routine?

Yes — Progeline, Matrixyl 3000, Argireline, Snap-8, and GHK-Cu work on different visual appearance. Add all peptide boosters to your serum, cream, or base blend well. Use morning and evening. Many combine 2–3 boosters in a single custom serum.

How long before I see visible firming results, and is this for mature skin or all skin types?

Most notice a visible improvement in the appearance of skin firmness and defined jawline within 4–6 weeks of consistent use. Results depend on % used and skin type. Progeline is for mature skin targeting the look of skin laxity (40s, 50s, 60s+)

Can I use this on my neck, jawline, and décolletage, or is it face-only?

Progeline was specifically developed to visibly address the appearance of skin laxity along the jawline, chin, neck. Add to any serum or moisturizer base for appearance of firmer, more lifted skin. Excellent addition to a neck and décolletage routine

Best Skincare Product Ever

I've been using this for about a year now and the results have been incredible, it took years off my jawline! My neck is so nice and firm, too. This is one of the best skincare products I have ever used. Being able to mix it in to other products is such a convenient solution, and a little can go a long way. I mix it with neutrogena hydroboost and apply it on top of tretinoin, because peptides increase tretinoin's effectiveness -- and these are truly some badass peptides. Then I use Laroche posay cicaplast as a barrier cream. So happy with it. There's a lot of skincare hype but this is the real deal, and an awesome value to boot!

Works Wonders!

I blend 3 droplets of Progeline serum with about 3 droplets of The Ordinary Hyaluronic Acid serum and it helps to create a soft but firmer facial and neck surface, and doesn’t cause any clogging of pores like many creams do. Make up can be applied easily over it and it helps reduce facial lines. I get many positive comments about my 73 year old skin. :)

An ok serum, but not a miracle.

Felt nice on my skin, but I was underwhelmed by the result.
