So Dr. Dennis Gross Skincare changed the formula on their iconic Alpha Beta peel. No fanfare. No announcement. Just a new ingredient list that landed in boxes. Early reviews are split — some say it’s glowier, others say it’s less effective. The real story? They swapped out a key acid. That changes everything.
🧪 **What You’re Actually Buying**
Still two steps. Still 35 pads for $92. The claim? “Professional-grade resurfacing at home.” I tested it because my usual retinoid wasn’t cutting it after summer sun damage. Here’s what’s new:
1. **Step 1 Formula Shift** – Lactic acid replaces glycolic. Gentler, but slower to show results.
2. **New Buffer System** – pH adjusted to 3.8 instead of 3.2. Less sting, more patience required.
3. **Step 2 Same** – Retinol, vitamin C, and soothing agents unchanged. Still smells faintly of cucumber and regret.

⚠️ **What’s Inside (and What’s Not)**
Glycolic acid is out. Lactic acid (10%) is in — better for moisture retention, worse for instant gratification. Niacinamide stays at 2% for barrier support. Licorice root extract for brightening. But here’s the kicker: salicylic acid dropped from 2% to 1.5%. If you’re oily, you’ll feel the difference.
– **Lactic Acid**: Exfoliates + hydrates. Slower than glycolic, but less irritation.
– **Niacinamide**: Calms redness, shrinks pores over time.
– **Licorice Root Extract**: Fades dark spots without bleaching.
– **Salicylic Acid (1.5%)**: Still clears pores, just less aggressively.

✨ **First Peel, Second Thoughts**
Texture is identical — watery, tingles on application, dries in 30 seconds. Step 2 feels like a light serum. My face flushed pink for 10 minutes. Not painful, just… aware. By morning, skin looked smooth but not glassy. The old formula gave me that “I just got a facial” glow by day 2. This one? Day 5.
Week 3 surprise: fewer breakouts, but my texture improved slower. The lactic acid is keeping moisture in — no peeling, no tightness. But I missed that instant grit-smoothing. It’s a trade-off.
💡 **One Thing** – Use Step 1 on dry skin only. Damp skin increases absorption too fast — you’ll get more irritation than exfoliation. Wait 60 seconds after cleansing.

📊 **The Numbers Don’t Lie**
After three weeks: pores looked 30% smaller (measured by my own obsessive mirror checks). Fine lines? Same. Dark spots faded by about 20% — slower than glycolic but zero new breakouts. My skin barrier stayed intact. No purging. That’s rare for an acid peel.
✅ **Buy if** – You have dry or sensitive skin and want gentle resurfacing without peeling.
⏭️ **Skip if** – You’re oily or acne-prone and need deep pore clearing fast. Old formula was better.
💰 **Worth it?** – For $92, you get 35 treatments. That’s $2.60 per peel. Fair, but only if your skin likes lactic acid.

🔄 **Final Call**
The 2026 formula is better for sensitive types, worse for oily skin. It’s a gentler, slower glow — not the instant transformation the old one delivered. I’d repurchase if my skin gets reactive, but I’d stockpile the old version if you can still find it.
**6.8/10** – Good, not great. Gentler glow, slower results.
🛍️ **Where to Buy** – Sephora or Dermstore. Grab the travel size ($29) first — don’t commit to a full box until you know if your skin likes lactic acid.
