All About Fixer: Skin Laundry's Peptide-Based Serum for Smoother, Firmer Skin

In the quest for firmer, smoother, more youthful-looking skin, peptides have emerged as one of skincare's most powerful ingredients. These amino acid chains work at a cellular level to stimulate collagen production, reduce the appearance of fine lines and wrinkles, and restore skin's natural resilience — all without needles, injections or downtime.

At Skin Laundry, we've harnessed the power of peptides in Fixer, our professional-grade topical serum enhancement. Available as an add-on to any of our dermatologist-designed Facials, Fixer takes your treatment results to the next level by delivering an ultra-concentrated blend of neurotransmitter-inhibiting peptides and botanical antioxidants directly to freshly treated skin when it's most receptive.

The result? Visibly smoother, firmer skin with reduced fine lines, minimized pores and a luminous, plumped finish that lasts for weeks after your appointment. 

What is Fixer?  

Think of Fixer, our peptide-based topical serum, as a "permanent-press" cycle for your skin. This professional-grade treatment, available as an enhancement after your facial, amplifies the results of your in-clinic session by stimulating collagen and elastin production while visibly minimizing the appearance of fine lines, wrinkles and enlarged pores. At the same time, it harnesses carefully selected botanical ingredients to calm inflammation, strengthen the skin barrier and uplevel the skin's overall health and resilience.

The results? Visibly smoother, firmer skin with a more even tone, refined texture and a luminous, radiant finish that extends the benefits of your facial for weeks to come.

Dr. Roberta Del Campo, chief medical officer at Skin Laundry and board-certified dermatologist, explains, "We design every treatment with the goal of reinforcing skin's natural resilience. With Fixer, we're delivering a topical treatment that echoes the results of in-office procedures — without needles or downtime. It's about giving the skin exactly what it needs, when it needs it most, to maximize the transformation our clients are seeking."

Understanding Peptides: The Building Blocks of Skin

Before diving into what makes Fixer so effective, it's important to understand what peptides are and why they've become a cornerstone ingredient in professional skincare.

Peptides are short chains of amino acids that serve as building blocks for proteins like collagen and elastin, which are essential for maintaining skin structure and firmness. Unlike full proteins, which are too large to penetrate the skin's surface, peptides can absorb into deeper skin layers where they act as messengers, signaling cells to produce more collagen and elastin.

As we age, our natural production of these essential proteins declines — we lose approximately 1% of our skin's collagen every year after age 30. This gradual depletion leads to visible signs of aging: fine lines, wrinkles, loss of firmness, enlarged pores and uneven texture.

By incorporating peptides into skincare, we can help rebuild a stronger skin barrier, plump skin to reduce the visibility of wrinkles, ease inflammation, repair damaged skin and even out skin tone. This makes peptides one of the most versatile and effective anti-aging ingredients available in professional skincare today.

How Does Fixer Work?

Fixer works through two complementary mechanisms that address both the muscular and structural causes of skin aging:

1. Muscle-Relaxing Peptides: Smoothing Expression Lines

Formulated with advanced neurotransmitter-inhibiting peptides, Fixer helps relax facial muscles that create expression lines from repeated movements. When applied topically, these specialized peptides work similarly to neuromodulators (like Botox) but without injections — they help temporarily reduce muscle contractions that lead to dynamic wrinkles around the eyes, forehead and mouth. The result is softer, smoother-looking expression lines and a more relaxed, refreshed appearance immediately after application.

2. Botanical Antioxidant Support: Stimulating Collagen Production

While the peptides work to relax facial muscles, Fixer's botanical extract complex delivers powerful antioxidants that protect against free radical damage while simultaneously boosting collagen and elastin production. This dual approach addresses both immediate concerns (fine lines and texture) and long-term skin health (structural integrity and resilience).

The botanical ingredients also provide anti-inflammatory benefits, calming any sensitivity or redness that may occur after laser or energy-based treatments and creating an optimal environment for skin healing and regeneration.

According to Dr. Del Campo, "When we combine active ingredients like peptides with our in-clinic treatments, we're able to elevate results of our facials significantly. Fixer helps extend the benefits of your facial long after you leave the clinic, essentially creating a bridge between professional treatments that maximizes your investment in your skin."

Key Ingredients in Fixer

Dr. Del Campo estimates that Fixer is at least 100 times more concentrated than typical over-the-counter serums or creams. "It's basically like putting pure peptides onto the skin," she explains. "This level of concentration is what makes Fixer a true professional treatment rather than a retail product — the potency delivers immediate, visible results that you simply can't achieve with most skincare."

Below, find a detailed breakdown of the powerhouse ingredients in Fixer and how they work synergistically.

Acetyl Hexapeptide-8 & Acetyl Hexapeptide-30

These advanced neurotransmitter-inhibiting peptides are the stars of Fixer's formula. They work by temporarily blocking the release of neurotransmitters that cause muscle contractions, effectively relaxing facial muscles and smoothing expression lines around the eyes, forehead and mouth.

Benefits:

• Reduces the appearance of dynamic wrinkles (those formed by facial expressions)
• Smooths crow's feet, frown lines and forehead creases
• Stimulates collagen synthesis for long-term anti-aging benefits
• Provides a visible "tightening" effect immediately after application
• Non-invasive alternative to injectable treatments

DMAE (Dimethylaminoethanol)

This naturally occurring compound is renowned in professional skincare for its remarkable lifting and firming effects. DMAE works at the cellular level to strengthen collagen fibers, improve skin tone and protect against oxidative stress that accelerates aging.

Benefits:

• Visibly lifts and firms sagging skin
• Strengthens and stabilizes collagen structures
• Protects against free radical damage
• Improves skin elasticity and bounce
• Enhances overall skin tone and radiance
• Reduces the appearance of jowls and loss of definition

Hibiscus Esculentus Extract

This botanical powerhouse, derived from the hibiscus plant, offers comprehensive skin benefits through its rich concentration of antioxidants, vitamins and natural alpha hydroxy acids.

Benefits:

• Provides potent antioxidant protection against environmental stressors
• Delivers anti-inflammatory benefits to calm and soothe skin
• Helps improve skin texture and tone
• Supports natural collagen production
• Protects skin barrier function
• Promotes a more even, radiant complexion

Green Tea Extract

One of nature's most powerful antioxidants, green tea extract contains polyphenols and catechins that offer exceptional protective and soothing benefits for the skin.

Benefits:

• Provides superior antioxidant protection against UV damage and pollution
• Soothes irritation and reduces redness
• Calms inflammation, particularly beneficial after laser treatments
• Protects against collagen breakdown
• Helps prevent premature aging
• Supports overall skin health and resilience
