Linerase vs Profhilo: Understanding Differences in Injectable Skin Rejuvenation


Linerase and Profhilo injectable model

Injectable treatments for skin rejuvenation have grown in popularity due to their minimally invasive approach and effectiveness in improving skin quality. Two treatments commonly used are Linerase and Profhilo, which differ in composition, mechanism, and clinical applications.


What is Linerase?

Linerase is an injectable formulation of micronized Type I collagen, derived from equine sources. It is designed to stimulate fibroblast activity, encouraging the production of new collagen in the skin. Linerase is primarily used for structural support in areas with collagen loss, improving elasticity and firmness. Visible improvement from Linerase can appear in 2-3 weeks with increased elasticity and firmness.


Key points about Linerase:

  • Active ingredient: Micronized Type I collagen (equine-derived)

  • Mechanism: Stimulates fibroblasts for collagen synthesis

  • Primary benefit: Improves skin firmness and dermal support

  • Injection depth: Mid-to-deep dermal layers

  • Common areas: Face, neck, hands

  • Recommended schedule: 2-4 sessions spaced 2-3 weeks apart


What is Profhilo?

Profhilo is an injectable stabilized hyaluronic acid (HA) treatment that hydrates and remodels the skin rather than filling wrinkles. It has one of the highest concentrations of HA among skin boosters, providing both moisture and bio-remodeling effects. Profhilo works by stimulating fibroblasts and adipose stem cells to improve skin texture, elasticity, and hydration. Its HA-based formula diffuses to bio-remodel the entire area for widespread skin revitalization.


Key points about Profhilo:

  • Active ingredient: Stabilized hyaluronic acid

  • Mechanism: Hydrates skin and stimulates bio-remodeling

  • Primary benefit: Skin hydration, elasticity, and texture improvement

  • Injection depth: Superficial to mid-dermal layers

  • Common areas: Face, neck, and fine lines around eyes and mouth

  • Technique: Employs the BAP technique for 5 specific injection points on each side of the face

Clinical Considerations

Treatment Goals:

  • Linerase is aimed at structural support and collagen restoration.

  • Profhilo is aimed at hydration, bio-remodeling, and skin elasticity.


Targeted Use:

  • Linerase is more suitable for areas with moderate to severe collagen loss, including the eyes, neck, and cleavage to address wrinkles and laxity.

  • Profhilo is suitable for early aging, dehydrated skin, and mild laxity.


Safety Profile:

  • Both treatments are generally well-tolerated. Linerase carries a small risk of allergic reaction due to animal-derived collagen. Profhilo’s main side effects are temporary redness or swelling. Unlike standard fillers, Profhilo does not contain any cross-linking agents, reducing the risk of adverse reactions.


Combination Potential:

  • In some cases, clinicians may combine these treatments for a dual approach: structural support with Linerase and hydration/skin remodeling with Profhilo.


Conclusion

Linerase and Profhilo offer different approaches to skin rejuvenation. Linerase focuses on collagen restoration and structural support, while Profhilo emphasizes hydration, elasticity, and bio-remodeling. Choosing between them depends on the patient’s skin condition, aging stage, and desired outcome. The effects of Profhilo usually last 1-1.5 years, requiring 1-2 maintenance treatments per year. Consulting a licensed aesthetic professional ensures a safe and effective treatment plan.
