As the demand for non-invasive aesthetic treatments continues to grow, so does the need for patient comfort during these procedures. One of the most effective and popular treatments on the market today is Morpheus8, a cutting-edge fractional skin treatment that combines microneedling with radiofrequency energy to tighten, tone, and rejuvenate aging skin.
While Morpheus8 is non-surgical, it’s not entirely pain-free. That’s why most medical spas, including Valley Medical Weight Loss, offer Pro-Nox during Morpheus8 treatments to ensure patient comfort and reduce anxiety.
In this post, we’ll explore what Pro-Nox is, how it works, and why it’s the ideal solution for making aesthetic treatments like Morpheus8 more comfortable. We’ll also cover everything you need to know about Morpheus8, including benefits, candidacy, side effects, and post-care.
What Is Pro-Nox?
Pro-Nox is an FDA-approved, self-administered nitrous oxide delivery system designed to provide pain relief and anxiety reduction during medical and aesthetic procedures. It’s a 50/50 blend of nitrous oxide (commonly known as laughing gas) and oxygen that you inhale through a mouthpiece.
Unlike general anesthesia, Pro-Nox doesn’t put you to sleep. Instead, it provides a mild sedative effect that keeps you awake, alert, and in control while significantly reducing pain and discomfort. The effects are almost immediate, and because the gas doesn’t bind to your hemoglobin, it exits your system within minutes.
Pro-Nox is more effective than topical numbing creams and more comfortable than injected anesthetics, making it the gold standard for pain management during aesthetic treatments.
Is Pro-Nox Safe?
If you’ve ever had dental work, wisdom teeth removed, or a minor surgical procedure, you’ve likely been given nitrous oxide. It’s been used safely in medical and dental settings for over 100 years.
Pro-Nox works by slowing your response time and creating a euphoric, relaxed feeling. When inhaled, it rapidly enters your bloodstream and takes effect within seconds. Because it doesn’t bind to your hemoglobin, it exits your system just as quickly, usually within 5 to 10 minutes after you stop inhaling.
This rapid onset and offset make Pro-Nox incredibly safe and convenient. You can drive yourself home shortly after your treatment, which is a major advantage over other forms of sedation.
What Are the Side Effects of Pro-Nox?
While Pro-Nox is generally safe, some patients may experience short-term side effects, including:
- Sweating
- Shivering
- Nausea
- Vomiting
- Dizziness
- Fatigue
These side effects are rare and typically resolve within minutes of stopping the gas.
You should let your provider know if you:
- Are pregnant
- Have COPD or a respiratory illness
- Have a methylenetetrahydrofolate reductase (MTHFR) deficiency
- Have a vitamin B-12 deficiency
- Have a history of mental health conditions
- Have a history of substance use disorders
- Have any of the microneedling or RF risk factors been discussed later in this post
Can You Overdose on Pro-Nox?
One of the reasons Pro-Nox is formulated as a 50/50 blend of nitrous oxide and oxygen is to virtually eliminate the risk of overdose. When used in a medical setting under appropriate supervision, overdose is highly unlikely.
According to Healthline, overdose is most likely to occur when nitrous oxide is taken in amounts many times greater than what’s used medically. This typically happens in cases of recreational abuse or addiction, not in a controlled medical environment like a med spa.
How to Use Pro-Nox During Morpheus8
Patient comfort is a top priority at Valley Medical Weight Loss. While topical numbing creams are an option, they don’t provide the same level of pain relief or anxiety management that Pro-Nox does.
Here’s what to expect when using Pro-Nox during your Morpheus8 treatment:
- Setup: Once your treatment area is prepped and ready, you’ll be given a mouthpiece connected to the Pro-Nox delivery system.
- Inhale: Breathe through the mouthpiece until you achieve the desired level of comfort and relaxation. The effects are almost immediate.
- Treatment: Continue using the mouthpiece as needed throughout your Morpheus8 session. You control the flow, so you can take breaks or adjust as needed.
- Recovery: After your treatment, you’ll need to wait 5 to 10 minutes before driving home. The gas exits your system quickly, so you’ll feel clear-headed and ready to go.

What Is Morpheus8?
Morpheus8 is a state-of-the-art, FDA-approved anti-aging treatment that combines microneedling with radiofrequency (RF) energy to remodel and rejuvenate sagging, crepey, wrinkled, discolored, or aging skin on the face and body.
The treatment targets the deeper layers of the skin, stimulating collagen and elastin production to tighten, tone, and smooth the skin from the inside out. On their own, microneedling and RF are powerful. Together, they’re optimized for maximum results.
How Radiofrequency Works
RF energy sends short, concentrated bursts of heat through the skin to stimulate collagen and elastin production. This tightens and tones the skin while improving texture and reducing wrinkles.
How Microneedling Works
Microneedling uses a series of ultra-fine needles to create controlled micro-injuries in the skin at depths ranging from 0.5mm to 8mm. This triggers the body’s natural healing response, which boosts collagen and elastin production and resurfaces the skin.
Microneedling isn’t as painful as it sounds, but it’s not entirely pain-free, which is why Pro-Nox is so valuable during Morpheus8 treatments.
What Can Morpheus8 Treat?
Morpheus8 is ideal for addressing a wide range of skin concerns, including:
- Skin tightening and firming
- Wrinkles and fine lines
- Acne scars and other types of scarring
- Enlarged pores
- Sun damage and hyperpigmentation
- Molar bags (under-eye puffiness)
- Sagging cheeks or jowls
- Loose or sagging abdominal skin
- Loose or sagging back skin
- Hyperhidrosis (excessive sweating)
You can further optimize your results by combining Morpheus8 with other treatments like Forma (radiofrequency skin tightening) and PRP (platelet-rich plasma).
What Areas of the Body Can You Treat with Morpheus8?
Morpheus8 is incredibly versatile and can be used on almost any area of the body, including:
- Face
- Jaw and neck
- Arms
- Abdomen
- Back
- Labia
- Legs
- Hands and feet
- Armpits (for hyperhidrosis)
You can start with one area and move on to the next as you see results. Each treatment is customized to your specific needs and goals.
Who Is Morpheus8 Right For?
The ideal candidate for Morpheus8 is:
- Between the ages of 30 and 55
- In relatively good health
- Experiencing visible signs of aging (wrinkles, sagging, loss of firmness)
- Looking for a non-surgical alternative to facelifts or body contouring
One of the most exciting benefits of Morpheus8 is that it’s safe for all skin types, including darker skin tones (Fitzpatrick types IV-VI). Most resurfacing treatments carry a higher risk of hyperpigmentation for darker skin, but Morpheus8 delivers anti-aging benefits with minimal risk.
Who Isn't Morpheus8 Right For?
A medical intake will be completed before your treatment to ensure you’re an ideal candidate for both Morpheus8 and Pro-Nox.
Morpheus8 may not be advised if you:
- Are pregnant
- Have severe active acne
- Are taking acne medications (such as isotretinoin)
- Have a blood disorder or are on anticoagulants
- Are undergoing chemotherapy or radiation
- Have a rash, dermatitis, or active cold sore
- Are prone to keloid scarring
- Have eczema or psoriasis
- Have a sunburn
- Have inflamed or irritated skin
How Long Does Treatment Take?
Your Morpheus8 treatment will take at least 60 minutes, and up to 90 minutes for larger treatment areas.
Because Pro-Nox exits your system quickly, many patients drive themselves home or even return to work after treatment. However, your skin will be red and you won’t be able to apply makeup for 48 hours, so plan accordingly.
How Long Does It Take to See Results?
Radiofrequency and microneedling stimulate collagen and elastin production immediately after treatment. This accelerated production continues for 3 to 6 months, which means your results will be almost immediate and will gradually improve over time.
A few weeks are required between treatments to allow the tissue to recover and for you to see the results.
Treatment Schedule:
- Light treatments: 2-4 sessions every 3-4 weeks
- Aggressive treatments: 1-3 sessions every 3-6 weeks
- Maintenance: Every 6 months
What Are the Side Effects and Post-Care for Morpheus8?
Here are the most common side effects and post-care guidelines for Morpheus8:
Immediate Side Effects:
- Erythema (redness): 1-3 days (may last longer for aggressive treatments)
- Edema (swelling): Mild to moderate, lasting 1-3 days
- Sunburn sensation: Mild to moderate, lasting 1-3 days
- Crusting and peeling: 2-7 days, depending on treatment settings
Post-Care Instructions:
- Apply Bacitracin and Aquaphor to the treated area for 2-3 days.
- Treat your skin gently. Avoid scrubbing or trauma to the treated area.
- Avoid sun exposure for 3 weeks to reduce the risk of hyperpigmentation.
- No makeup for 48 hours.
- Use a zinc oxide sunblock (SPF 30+) at all times starting 48 hours post-treatment.
- Change your pillowcase the evening of your treatment to avoid bacteria near the treated area.
- Avoid touching your face with your cell phone for 48 hours. Use a speakerphone or earbuds.
- Contact us immediately if you experience signs of infection, excessive swelling, redness, pain, or any other unusual symptoms.
The Bottom Line
