NEOCUTIS Bio Serum Firm hydrating anti-aging serum, 30ml — peptides & sodium hyaluronate

NEOCUTIS Bio Serum Firm is a concentrated 30ml serum that blends high-strength proprietary peptides, human growth factors and sodium hyaluronate to hydrate, firm and refine the look of aging skin.

Designed by NEOCUTIS researchers, this serum merges technologies from Micro Serum and Bio Serum into a single, multifunctional formula. It prioritizes moisture delivery and peptide-driven skin support while using sodium hyaluronate — a lower-molecular-weight humectant — to draw and hold water more effectively than standard hyaluronic acid. The lightweight texture layers well under moisturizers and makeup and is supplied in a 1 fl. oz bottle, roughly a three-month supply with typical daily use.

How does Bio Serum Firm hydrate and plump skin?

The serum uses sodium hyaluronate to attract and retain moisture within the skin’s surface for immediate and lasting hydration. Paired with supportive humectants and stabilizing ingredients, it helps skin look smoother and appear more supple over time.

• Sodium hyaluronate for rapid moisture uptake and retention
• Lightweight base for fast absorption without stickiness
• Compatible with most moisturizers and sunscreen routines

What anti-aging benefits do the peptides and growth factors provide?

NEOCUTIS combines high concentrations of proprietary peptides with human growth factors to support the skin’s visible texture, tone and elasticity. These actives aim to reduce the look of fine lines and roughness while supporting a firmer appearance when used consistently.

• Proprietary peptide complex targets signs of aging and texture concerns
• Human growth factors help improve the skin’s overall appearance
• Formulation supports smoother, more even-looking skin over time

When can I expect to see results and how should I use it?

According to internal data from the brand, visible improvements in brightness, hydration and refinement were observed in as soon as six days for some users; individual results will vary. For best integration into a daily routine, apply a few drops to cleansed skin morning and/or evening, follow with moisturizer and SPF during daytime.

• Apply to clean, dry face and neck; pat gently until absorbed
• Use morning and/or night—follow with sunscreen during the day
• One 30ml bottle typically lasts about three months with regular use

Is this serum suitable for sensitive or combination skin?

The formula is designed to be lightweight and hydrating, which generally suits combination and many sensitive skin types, though patch testing is recommended for very reactive skin. Its focus on moisturization and peptide support reduces reliance on heavier emollients, making it a versatile layering product.

• Light texture minimizes pore-clogging risk for combination skin
• Sodium hyaluronate provides hydration without heavy oils
• Patch test new actives if you have a history of sensitivity

Who is this for: NEOCUTIS Bio Serum Firm is intended for adults seeking a performance-driven serum that combines advanced peptides, human growth factors and potent humectants to address moisture loss, early-to-moderate signs of aging and uneven texture. It's a good option for those who prefer scientifically oriented skincare with a light, layerable feel and who want to fold a targeted peptide/growth-factor product into an existing regimen. If you have very reactive conditions or are using prescription topical treatments, consult a skincare professional before adding new active products.
