Anti-Aging | 

The Hero of Any Anti-Aging Regimen

By ZO® Skin Health


Two years ago, ZO® launched its best-selling Firming Serum, an anti-aging breakthrough in skin structure + shape. Firming Serum has since become a bestseller, supporting all skin types with its mild, lightweight, tolerable formulation and exclusive technology.

What makes Firming Serum an invaluable addition to any anti-aging regimen? There are many ways that Firming Serum distinguishes itself from other solutions, both at-home and in-office.

Key Ingredient Technologies

One of the most efficacious technologies of Firming Serum is the ingredient Sodium DNA. As we age, the cellular processes that restore collagen and elastin – that help maintain the appearance of firm skin – naturally degrade, which results in signs of aging, such as wrinkles, sagging and thinning skin. Sodium DNA works deeper in the skin to help to support skin health for a more defined facial contour.

In addition, Firming Serum contains two exclusive ZO® technologies that set it apart from other anti-aging solutions. ZCORE™ is an exclusive firming complex that improves the visible appearance of skin sagging. Whereas ZO-RRS2® provides powerful antioxidant benefits while calming skin + reducing the visible appearance of redness.

The ingredient technologies of Firming Serum are also supported by a 24-week clinical study. Highlights from the study include:

  • 97% of patients showed significant improvement in firmness
  • 93% of patients showed significant improvement in both mid-face and jawline sagging
  • 88% of patients showed improvement in skin elasticity

Protocol: A 24-week third party-led clinical study on 45 subjects to assess product efficacy of the Firming Serum. Supported with the Gentle Cleanser and Sunscreen + Primer SPF 30.


Anti-Aging Solution for All Aging Concerns

Firming Serum is a base product for every anti-aging protocol. It improves the appearance of firmness and elasticity and hydrates to support skin’s ability to keep its structural integrity and shape. Its gentle and lightweight formulation is ideal for all skin types.

Firming Serum can also be paired with other products to complement existing anti-aging regimens and amplify results. For example, Daily Power Defense and Firming Serum work synergistically to restore hydration, smoothness and overall skin health.

Supports In-Office Treatments

Looking to get the most out of your in-office anti-aging treatments? Consider incorporating the power of Firming Serum into your routine. Firming Serum Accelerated is a highly concentrated add-on that can maximize the anti-aging benefits of a variety of treatments. Not only does it offer visible improvements in skin laxity, but the flash filler effect offers intense hydration benefits to reinforce skin health both in-office and at home to support long-lasting results. In addition, Firming Serum Accelerated has been tested to be used safely with microneedling.
