Skin Perfection Progeline Firming Serum Booster 0.5 fl oz — concentrated peptide booster for jawline, neck & décolletage

Skin Perfection Progeline Firming Serum Booster is a concentrated DIY peptide liquid designed to be mixed into creams or serums at 0.5–2% to target the appearance of firmness in the jawline, jowls, neck, and décolletage.

This professional-grade 0.5 fl oz booster contains Progeline (Trifluoroacetyl Tripeptide-2) in a light, water-soluble base so you can create fresh, high-strength firming treatments at home. Packaged in protective blue glass to preserve peptide stability, the formula is free from parabens, fragrances, fillers, and animal testing. It’s intended for dilution into your favorite cream, gel, or hyaluronic acid serum—never applied neat—and includes a clear mixing guide to achieve target concentrations safely.

How should I mix and use this Progeline booster?

Add the booster to any compatible water-based base (cream, serum, aloe gel, hyaluronic acid) at 0.5–2% depending on sensitivity and goals. Start at 0.5% if you’re new to peptides, then step up to 2% for full-strength results once you tolerate it. Use morning and evening after cleansing; follow with moisturizer and daily SPF in the morning.

• Add 18 drops to 1 oz (30 ml) of base for a 2% concentration.
• Mix thoroughly and store finished mixes in a cool, dry place; use within 3 months.
• Perform a patch test and avoid direct eye contact; discontinue if irritation occurs.

Which areas will benefit from a Progeline peptide blend?

Progeline is formulated to address the appearance of sagging and loss of definition in lower-face and neck zones where volume and firmness change with age. It’s typically used along the jawline, under the chin, jowls, neck bands, and décolletage; with caution, small amounts can be included around the eyelid area to support a firmer look.

• Jawline and jowls: targeted application along the jaw edge.
• Under-chin and neck: front and sides including necklace lines.
• Décolletage and lower face: marionette lines and chest area.

Can I combine Progeline with other peptides or actives?

Yes—this booster was designed for peptide stacking so you can create multi-action formulas. Common pairings include Matrixyl 3000 for collagen support, Argireline for expression-line appearance, copper peptides for overall skin tone, or hyaluronic acid for hydration. Avoid mixing with strong acids or freshly applied retinoids without spacing applications.

• Matrixyl 3000 + Progeline for collagen and firmness support.
• Argireline + Progeline to address expression lines and lower-face sagging.
• Hyaluronic acid base for a hydrating, fast-absorbing serum.

What results and timeline should I expect using this booster?

Individual responses vary, but many users report increased hydration and a mild tightening sensation within the first two weeks. Visible improvements in jawline definition and neck smoothness commonly appear between 4–8 weeks, with further gains after consistent use for 10–12 weeks. Continued application twice daily helps maintain and build results.

• Weeks 1–2: improved hydration and subtle tightening.
• Weeks 3–8: gradual firming and better jawline appearance in photos.
• Weeks 10–12+: more noticeable definition and ongoing improvement with use.
