Can Nicotine-Free Vapes Still Cause Acne? What You Need to Know

Vaping has become a popular alternative to smoking, with millions of users worldwide. While it’s often perceived as a “healthier” option, questions remain about its potential hidden effects. One of the more surprising queries is: Does vaping have calories? And if so, could it affect your skin or hormones? Let’s break this down scientifically.

Does Vaping Contain Calories?

What’s Inside Vape Juice?

E-liquids, or vape juices, usually consist of the following ingredients:

• Propylene Glycol (PG)

• Vegetable Glycerin (VG)

• Nicotine (optional)

• Flavorings

Of these, VG and some flavorings are calorie-containing substances.

Caloric Content of VG and PG

• Vegetable Glycerin: About 4.3 calories per gram

• Propylene Glycol: Roughly 4 calories per gram

However, the key issue is bioavailability—whether these calories are absorbed into your system during vaping.

Are Vape Calories Absorbed?

Unlike eating or drinking, inhaled substances don’t go through the digestive tract, so the body doesn’t metabolize them in the same way. Even though VG and PG are caloric compounds, inhaling them doesn’t provide usable energy to the body.

In short:
👉 Yes, vape juice contains calorie-based ingredients, but those calories are not metabolized in a way that would impact your weight, hormones, or energy levels.

Can Vaping Impact Your Skin?

While calories from vaping aren’t absorbed, vaping can have notable effects on your skin—just not from energy intake.

Effects of Vaping on Skin Health

Nicotine and other compounds in vape juice can impact your skin in the following ways:

1. Dehydration

Nicotine is a vasoconstrictor—it narrows blood vessels, reducing blood flow to the skin. This can cause:

• Dryness

• Dull complexion

• Premature aging

2. Collagen Breakdown

Nicotine reduces the production of collagen and elastin, two proteins that keep skin youthful and elastic.

3. Oxidative Stress

Many vape liquids generate free radicals during combustion. These damage cells and accelerate skin aging.

4. Increased Acne

Some users report breakouts linked to:

• Hormonal fluctuations triggered by nicotine

• Skin inflammation

• Touching the face frequently while vaping

Does Vaping Affect Hormones?

Nicotine’s Hormonal Impact

Nicotine is a powerful stimulant, and it does interact with the endocrine system, influencing several hormones:

1. Cortisol (The Stress Hormone)

• Nicotine spikes cortisol levels

• Elevated cortisol may lead to:
  • Weight gain (especially abdominal fat)

  • Increased stress

  • Disrupted sleep

2. Insulin and Blood Sugar

• Vaping may impair insulin sensitivity

• Increased risk of insulin resistance and blood sugar imbalances

3. Estrogen and Testosterone

• Long-term nicotine use can suppress estrogen in women and testosterone in men

• This may lead to:
  • Irregular menstrual cycles

  • Lower libido

  • Mood swings

Vaping vs. Smoking: Which Is Worse for Skin and Hormones?

While traditional cigarettes are more harmful overall, vaping isn’t risk-free.

Comparison Table

Bottom line: Vaping may be “safer” than smoking but still negatively impacts skin and hormone health.

Additional Compounds in Vape Juice

Some flavored vape liquids contain additives like:

• Diacetyl: Linked to “popcorn lung”

• Benzaldehyde: Found in cherry flavors; can irritate airways

• Cinnamaldehyde: Found in cinnamon flavors; may affect immune cells

These additives can further stress your body, potentially amplifying skin issues and internal hormonal imbalances.

What About Non-Nicotine Vapes?

Non-nicotine vape products are often marketed as “harmless,” but are they?

Potential Effects of Non-Nicotine Vaping

• Still contain VG, PG, and flavorings

• May cause skin dryness and inflammation

• Do not impact hormones directly but could still irritate the body due to inhaled chemicals

Important Note: Even without nicotine, the act of vaping may contribute to oxidative stress and systemic inflammation.

How to Protect Your Skin and Hormones if You Vape

If you’re not ready to quit vaping, here are a few tips to help minimize the effects:

Skin Protection Tips

• Stay hydrated – vape-related dehydration is real

• Use antioxidant serums – Vitamin C can help combat free radicals

• Moisturize regularly – counteract dryness and dullness

• Sunscreen daily – vaping doesn’t cause UV damage, but combined stressors accelerate aging

Hormonal Balance Tips

• Manage stress naturally – incorporate yoga, meditation, or breathwork

• Eat a hormone-friendly diet – rich in omega-3s, leafy greens, and whole grains

• Sleep well – nicotine disrupts sleep; consider limiting vaping before bed

• Exercise regularly – supports both hormone balance and skin health

Final Verdict: Do Vape Calories Matter?

Summary Points

• Vape liquids do contain caloric ingredients (VG and PG), but they are not absorbed through the lungs like food or drink.

• Therefore, vaping does not contribute to your caloric intake or affect your weight.

• However, vaping can affect your skin and hormones due to the physiological effects of nicotine and other chemicals.

Final Thoughts

While vaping doesn’t add calories to your diet, its impact on skin health and hormonal balance shouldn’t be ignored. Whether you vape with or without nicotine, the chemical exposure may lead to premature aging, hormonal shifts, and increased stress levels.

If your goal is to improve your health, skin, and hormone balance, consider reducing or eliminating vaping. If quitting feels overwhelming, consult a healthcare professional for support and explore nicotine replacement therapies or behavioral strategies.
