If your face turns bright red after just one drink, you’re not alone. This reaction, known as Alcohol Flush Reaction or “Asian Flush,” affects roughly one in three East Asians, and many others worldwide.

That redness isn’t just surface deep. It’s a visible sign that your body is struggling to process alcohol efficiently — specifically, a toxic by-product called acetaldehyde.

What Causes Alcohol Flush Reaction?

When you drink, your body breaks alcohol down in two main steps:

1. Ethanol → Acetaldehyde (a toxic, inflammatory compound)
2. Acetaldehyde → Acetate + Water (harmless, eventually used for energy)

The issue lies in step two.
Most people convert acetaldehyde quickly thanks to an enzyme called ALDH2 (aldehyde dehydrogenase 2).

But for millions of people — especially those with an ALDH2 gene variant — this enzyme works slowly or inefficiently. The result:

• Acetaldehyde builds up in the bloodstream
• Blood vessels dilate → your face flushes
• You may also feel nausea, dizziness, warmth, or a racing heart

That redness is your body’s way of saying, “Hey, I’m having a hard time keeping up.”

Why the Flush Matters

For many, alcohol flush reaction is both uncomfortable and socially frustrating — but it also matters for your health.

When acetaldehyde lingers, it doesn’t just cause redness — it can:

• Trigger headaches, nausea, and fatigue
• Disrupt sleep and mood
• Contribute to oxidative stress and inflammation
• Increase long-term health risks with repeated exposure

So while the redness might seem harmless, it’s actually your body sending a clear signal: support me.

How iBlush Helps

At iBlush, we created our products to target the root cause of alcohol flush — acetaldehyde buildup.

Unlike “quick fixes” that simply mask redness, iBlush helps your body handle alcohol more efficiently with a science-backed blend of antioxidants and vitamins that support natural detox pathways.

How It Works

Each iBlush Patch, Tablet, or Gel is formulated with key ingredients like:

• Glutathione: Binds and neutralises acetaldehyde.
• N-Acetyl Cysteine (NAC): Boosts your body’s own glutathione production.
• R-Alpha Lipoic Acid (R-ALA): Regenerates antioxidants to reduce oxidative stress.

These ingredients work together to:

• Support healthy enzyme activity
• Help clear acetaldehyde faster
• Reduce redness, nausea, and discomfort

💡 Think of iBlush as your body’s support system, not a cover-up. It helps you drink more comfortably, without the flush or the fear.

The Bottom Line

Alcohol flush reaction isn’t “just blushing.” It’s your body showing you that acetaldehyde (not alcohol itself) is the real problem.

Supporting your body’s natural metabolism with antioxidants like glutathione helps you process alcohol more efficiently and recover faster.

That’s the science behind iBlush: drink smarter, feel better, and enjoy the moment — confidently.
