1.☀️Timing Is Everything

Your hyaluronic acid isn’t working because you’re slapping it on dry skin like a psychopath. Here’s the deal — Pestle & Mortar Pure Hyaluronic Serum needs water to grab onto, or it’ll actually dehydrate you.

Apply to sopping wet skin — like, dripping. I pat mine on before I even towel off. That’s the difference between “meh” and “whoa my face feels like a jelly donut.”

1.🌙Wait, Actually

It’s $42 for 30ml. The claim: “500x its weight in water retention.” I rolled my eyes too. Then I tried it.

1

Triple-weight HA

Three molecular sizes — big ones sit on top, small ones drill down deep. Most brands do two.

2

No filler bullshit

No fragrance, no alcohol, no silicones. Just the good stuff.

3

Absorbs in 12 seconds

I timed it. Dries down tacky but not sticky — perfect for under makeup.

1.🔬The Science Bit

Sodium Hyaluronate is the MVP here — it’s the salt form of HA, which penetrates deeper and lasts longer. Plus they added Panthenol (B5) so your barrier doesn’t throw a tantrum.

  • Sodium Hyaluronate: Penetrates deeper than plain HA — stays put
  • Hydrolyzed Hyaluronic Acid: The micro-molecule that fills fine lines from within
  • Panthenol: Calms irritation + holds moisture like a sponge
  • Glycerin: The backup singer that keeps everything locked in

1.🧴Feels Like

Water. Literally clear, runny water — but the second it hits damp skin it turns into this silky glide. No pilling. No weird film.

Week 2: My forehead lines looked… confused? Like they forgot they were supposed to be there. Not gone, but definitely questioning their life choices.

💡

One Thing: Mist your face with thermal water *after* applying, then seal with an oil. The extra water layer doubles the plump effect — trust me.
1.The Honest Results

Morning: skin drinks this up. By noon my T-zone isn’t a grease slick. Night: wake up with that “I actually slept 8 hours” look. Pores? Same size. Texture? Smoother.
