So I got this serum from Mary&May because the claim was basically: *what if AHAs didn’t sting?* That’s a lie I’ve heard before, but blackberry extract as a natural source of glycolic + lactic acid? That’s new. Most “natural acids” are just marketing fluff. This one actually made my face feel smooth the next morning — not raw, not tight. Just… softer.
The real kicker? No purge. At all. I usually get those tiny whiteheads around my chin when I start a new acid. Nothing here. Zero irritation. My skin looked better on day 2. That almost never happens.
🍇 **What You’re Actually Buying**
It’s a serum, not a toner. About $20-22 depending on where you grab it. The bottle is annoyingly small (30ml) but you only need 2-3 drops. The claim that got me: “brightening without barrier damage.” Bold. I tested it.
1. **Blackberry-derived AHA** – Naturally occurring glycolic + lactic. Gentle enough for daily use. I didn’t believe it either.
2. **Tetra 10% Vitamin C derivative** – Not pure L-ascorbic (which oxidizes in a week), but a stable, less irritating form. Smart.
3. **Panthenol + Madecassoside** – They’re here to babysit the actives. And it works.
✨ **Ingredients That Actually Do Something**
The formula is dumb simple — 8 ingredients. No filler oils, no fragrance, no essential oils trying to be “natural.” The hero is the blackberry extract fermented to release natural AHAs. It’s not as potent as a 10% glycolic peel, but that’s the point. It’s for *maintenance*, not punishment.
– **Blackberry Fruit Extract**: Natural AHA source. pH-balanced so it doesn’t burn.
– **Ascorbyl Tetraisopalmitate (10%)**: Stable vitamin C. Brightens without the sting.
– **Panthenol**: Calms everything down. Prevents the “acid flush.”
– **Madecassoside**: Speeds healing. Keeps barrier intact.
🧪 **Texture + My Actual Experience**
It’s a watery gel. Absorbs in maybe 8 seconds — no joke. No sticky film. No smell (thank god). I put it on after cleansing, before moisturizer. First morning my skin looked… hydrated? Not miraculous. Just plump.
Week 2: The surprise was *texture*. My nose pores looked smaller. Not gone — that’s a filter, not skincare — but less obvious. The dark spot from a December pimple faded maybe 40%. Slow, but steady. What didn’t change: my deep sunspots. Those need laser. No serum fixes those.
💡 **One Thing** – Apply on *damp* skin. Straight after washing. It spreads better and you need half the drops. Makes the bottle last 6+ weeks.
📊 **Real Results After 3 Weeks**
Measurable: skin tone is more uniform. My “red patches” around the nose calmed down. The glow isn’t dewy — it’s more like light bounces off instead of getting stuck on dry patches. What stayed the same: my hormonal chin acne. This won’t fix acne. It’s for brightness, not breakouts.
✅ **Buy if** – you have normal to combo skin and want daily mild exfoliation without peeling like a lizard.
⏭️ **Skip if** – you’re using prescription retinoids or have active cystic acne. Too many actives.
💰 **Worth it?** – Yes, for $20. It’s cheaper than a coffee run per week. But buy the 30ml first — don’t commit to the big bottle until you know your skin likes it.
💡 **Final Take**
This is the “I want results but I’m scared of acids” serum. It won’t transform your face in a week. But after a month? You’ll notice your skin is just… better. No drama. No irritation. Just steady improvement.
**8.2/10** – Smart, gentle, actually works.
🛍️ **Where to Buy** – Direct from their site or Amazon. Get the travel size first ($12) to test tolerance.
