Nobody announced it. One day it was the same purple bottle — but the texture lied. The new Sunday Riley Good Genes feels thinner, slides faster, and dries down in about 8 seconds flat. The old one? That sticky, almost tacky finish that forced you to wait before moisturizer? Gone.
This matters because the old formula wasn’t just a serum — it was a texture experience. The new one behaves like every other lactic acid. And that changes how you layer it.
🔄 **What You’re Actually Getting**
$122 for 1.7 oz of lactic acid that claims to exfoliate, brighten, and smooth in one step. I bought it because the original made my skin look like I’d slept 10 hours — even when I hadn’t.
1. **Lactic Acid (5%)** — pH-optimized to exfoliate without that sting
2. **Purified Purslane Extract** — calms redness better than aloe ever did
3. **Lichen Extract** — supposedly boosts glow, honestly just feels nice
4. **Propanediol** — the main reason it now absorbs instantly, for better or worse
📉 **Ingredients: What’s Actually Inside**
The old formula had a higher percentage of lactic acid and a thicker, almost jelly-like base thanks to more stabilizing gums. The new one swaps those for lighter solvents — so the exfoliation feels gentler, but the “tightening” sensation is completely gone.
– **Lactic Acid**: Surface exfoliation + moisture binding — but less sting now
– **Purslane Extract**: Antioxidant that actually reduces redness, not just marketing
– **Lichen Extract**: Brightening claims are real-ish — takes 3 weeks to see it
– **Sodium Hyaluronate**: Hydration that doesn’t pill under makeup anymore
✅ **Texture & First Impressions**
Squeezed it out and it ran between my fingers — watery, almost like a toner. Spreads across your face in one swipe. No tackiness. No waiting. I actually missed the stickiness for a second — it made me feel like something was *happening*.
Week 2: My chin texture smoothed out faster than with the old formula. But my cheeks — which loved the old version — looked a little duller. The new one doesn’t hold moisture the same way.
💡 **One Thing** — Apply to damp skin. The new formula evaporates so fast that dry application leaves you with half the product absorbed.
❌ **Real Results — The Honest Version**
Fine lines around my mouth: slightly softer. Pores near my nose: visibly smaller — but only for about 6 hours. Blackheads? Same. The old formula actually softened them over time; this one just sits on top.
✅ **Buy if** you have oily combination skin and hate waiting between steps
⏭️ **Skip if** you’re dry or dehydrated — you’ll miss the old formula’s moisture
💰 **Worth it?** Only at the Sephora sale (20% off or wait) — $122 is too much for a serum that now feels like a toner
💬 **My Final Call**
The new Good Genes is a perfectly fine lactic acid serum. The old one was *the* lactic acid serum. If you never tried the original, you’ll probably love this. If you did? You’ll notice.
🏆 **6.5/10** — Good acid, bad reformulation
🛍️ **Where to Buy** — Sephora or directly from Sunday Riley. Grab the $48 travel size first — seriously, don’t blind buy the full bottle.
