16 oz — 30-Day Supply Liquid Collagen + Vitamin C 90% Faster Absorption vs. Capsules Preferred by Professionals
Collagen + C Plus Liquid — Professional Liquid Collagen Supplement for Spa Retail & Anti-Aging Treatments (16 oz)
She finishes her facial. Her skin is glowing. And then she asks the question every esthetician loves to hear: "What can I take home to keep this going?"
Most supplements will let her down — and when results fade, she'll wonder if it was really your treatment that made the difference. But this one delivers. Liquid collagen, absorbed up to 90% faster than capsules, reaching her skin, hair, and nails within days instead of weeks.
When she calls two weeks later saying "my skin has never looked like this" — she's not calling her supplement. She's calling you.
Trusted by professional estheticians across the United States as their go-to retail collagen supplement, Collagen + C Plus Liquid combines hydrolyzed collagen peptides with Vitamin C — the essential cofactor that activates the body's own collagen synthesis. One bottle. 30 days. A client who glows, refers friends, and never misses a rebook.
Why Liquid Collagen Outperforms Capsules and Powders
Not all collagen supplements are equal. The form matters as much as the formula:
Capsules & Powders
Traditional Format
✗ Collagen molecules too large — partially blocked by digestive enzymes
✗ Absorption rate: 20–30% of active content reaches bloodstream
✗ Results take 8–12 weeks to become visible
✗ Clients often give up before seeing results
✗ No synergistic cofactors in most formulas
Collagen + C Plus Liquid — Best Choice
Liquid Hydrolyzed Formula
✓ Pre-broken peptide chains — ready for immediate absorption
✓ Absorption rate: up to 90% reaches bloodstream directly
✓ Results visible in 4–6 weeks — clients stay motivated
✓ Clients complete the full protocol and reorder
✓ Vitamin C included — activates client's own collagen production
The Business Case: Your Best Retail Margin in the Spa
At $14.50 wholesale, this is one of the highest-margin retail products you can stock. Every treatment you perform is an opportunity to recommend it — and every bottle sold works 24 hours a day to extend your results in your client's home:
| Retail Scenario | Your Cost | Retail Price | Your Profit | Monthly (20 clients) |
|---|---|---|---|---|
| Single bottle sale | $14.50 | $28 – $35 | $13.50 – $20.50 | $270 – $410 |
| 3-month program | $43.50 | $75 – $90 | $31.50 – $46.50 | $630 – $930 |
| Anti-aging package add-on | $14.50 | Included in $200+ pkg | Increases package value & close rate | +$400 – $800 / month |
Cost per day: $0.48. That's what your client invests daily for firmer skin, stronger nails, and thicker hair. Retail it at $28–$35 and you earn $13.50–$20.50 profit per bottle — from a product that sells itself because it actually works. And when clients see their skin changing at home, they credit your expertise and rebook faster.

Active Ingredients — The Science Behind the Glow
Two powerhouse actives working in synergy — one replenishes, one activates:
Collagen Complex
Hydrolyzed Marine Collagen Peptides Pre-broken into small peptide chains (Type I & III) for maximum absorption. Reaches the dermis where it replenishes collagen fibers lost through aging, UV exposure, and lifestyle factors. Directly supports skin firmness, elasticity, and hydration.
Collagen Type I & III Type I is the primary collagen of skin — responsible for its firmness and smoothness. Type III supports skin elasticity and is critical for hair and nail strength. Together they address the full spectrum of visible aging concerns.
Synthesis Activators
Vitamin C (Ascorbic Acid) The essential cofactor for collagen synthesis — without Vitamin C, the body cannot produce collagen regardless of intake. This formula doesn't just supplement collagen; it activates the client's own collagen-production pathway for compounding, lasting results.
Antioxidant Complex Neutralizes free radicals that break down existing collagen, protecting the collagen your client already has while building new fibers — a dual action that accelerates visible anti-aging results.
How to Recommend It in Your Spa
When to Introduce to Clients
- After every anti-aging facial. The moment the client sees her glowing skin in the mirror is your best selling opportunity. "Your skin responds beautifully to collagen stimulation — this liquid supplement extends what we just did for the next 30 days."
- After body contouring and RF sessions. RF stimulates collagen in body tissue too. Recommend Collagen + C Plus to maximize and prolong the firming results your clients feel after their session.
- As part of a skin transformation program. Bundle 3 bottles for a 90-day program. Clients who commit to 3 months see transformational results — and become your most vocal advocates.
- For clients over 35. After 35, the body's natural collagen production declines by approximately 1% per year. Frame it as maintenance: "Your skin is working against you every day. This helps you stay ahead."
- At checkout — every single visit. Keep it visible on your retail shelf. A simple "Are you taking your collagen?" at the end of each appointment creates a consistent retail conversation with zero pressure.
Best Paired With These Treatments
- Anti-Aging Facials — the ultimate post-facial retail recommendation to extend results at home
- Radiofrequency Sessions — internal collagen supplementation amplifies the external collagen stimulation from RF heat
- Body Contouring Treatments — supports skin firmness as fat reduces, preventing skin laxity in treated areas
- Post-Op Recovery Programs — liquid collagen accelerates tissue repair and healing after BBL and liposuction
- BeYOUTH Exosome Serum — the most powerful internal + external anti-aging combination in the SlimSpa lineup

Frequently Asked Questions
Why is liquid collagen better than collagen capsules or powders?
Collagen in capsule or powder form contains larger protein molecules that are partially blocked by digestive enzymes — studies suggest only 20–30% of the active content actually reaches the bloodstream. Liquid hydrolyzed collagen consists of pre-broken peptide chains that bypass this barrier and are absorbed directly, with absorption rates up to 90%. The practical difference: clients see results in 4–6 weeks rather than 8–12 weeks — keeping them motivated and loyal to your recommendation.
Why does this formula include Vitamin C?
Vitamin C is the essential cofactor for collagen synthesis — without it, the body cannot produce collagen regardless of how much you supplement. Most collagen products don't include it, which limits their effectiveness. Collagen + C Plus pairs hydrolyzed collagen peptides with Vitamin C to create a complete formula: one component replenishes existing collagen, the other activates the body's own production. The result is a compounding effect that capsule-only supplements can't replicate.
Who is the ideal client for this product?
Any client over 25 benefits from collagen supplementation, as natural production begins declining in the mid-20s. The ideal clients are women over 35 noticing fine lines, loss of skin firmness, or thinning hair and nails; post-op recovery clients who need accelerated tissue repair; clients undergoing anti-aging facials, RF treatments, or body contouring who want to extend results; and clients concerned about skin health, joint comfort, or overall vitality.
Can I put my spa's name on the label?
Yes. SlimSpa's private label program lets you brand Collagen + C Plus Liquid with your spa's name, logo, and identity. Minimum order quantities apply. Private label clients receive up to 20% off wholesale pricing and the ability to create a signature product that builds client loyalty and elevates your brand. Contact us at slimspaonline.com for program details.
How should clients take it and how long before they see results?
The recommended dose is taken once daily — typically in the morning with or without food. Many clients prefer to mix it with their morning juice or smoothie for palatability. Most notice improved skin hydration and glow within the first week. Stronger nails and thicker hair become apparent by weeks 2–3. Visible skin firming and reduction of fine lines typically appears between weeks 4–6. Maximum results are seen with consistent use over 3 months, which is why the 3-month program bundle is such a strong retail offering.
Is it safe to take alongside other supplements or treatments?
Yes. Collagen + C Plus Liquid uses naturally-derived ingredients and is generally safe to take alongside other supplements. It pairs especially well with hyaluronic acid, biotin, and omega-3 supplements. As with any dietary supplement, clients who are pregnant, nursing, or managing a medical condition should consult their healthcare provider before starting. It complements — rather than interferes with — all professional body contouring and skin treatments.
The Supplement That Keeps Working When Your Clients Leave the Spa.
Every bottle of Collagen + C Plus Liquid you sell is 30 days of daily results — results your clients will credit to your expertise, your recommendations, and your spa. Stock it, recommend it, and watch your retail revenue build itself.
