30-Day Test
I replaced my foundation with this stick for a month — here’s what happened to my pores, my glow, and my confidence.
Expert Analysis · Honest Reviews · Real Results
1.📆Ditched My Foundation

Day one I swiped this stick across my face and immediately texted my group chat “wait what.” It melted in like a tinted moisturizer that actually has opinions.

By day 30 I had stopped reaching for my liquid foundation entirely — and my pores didn’t throw a tantrum about it.

2.🪞What The Stick Actually Does

It’s a solid balm that claims to be foundation, skincare, and glow in one stick. $54 at Yves Saint Laurent. I rolled my eyes, then I bought it.

1

Melting texture

Swipes on like butter, then sets in 30 seconds — no blending sponge needed

2

Sheer-to-medium coverage

Hides my redness but my freckles still show. That’s the sweet spot.

3

Built-in sponge applicator

Actually useful. I just dab and go. Doesn’t get gross if you clean it weekly.

3.📸The Ingredient Gossip

They packed this with skincare actives that actually do something. The hero is hyaluronic acid for plumping, plus squalane for moisture. But the surprise MVP? Glycerin — it’s the real glow driver here.

  • Hyaluronic Acid: Holds 1000x its weight in water — plumps fine lines instantly
  • Squalane: Mimics your skin’s natural oil, so no greasy feeling
  • Glycerin: Draws moisture from air into skin all day
  • Niacinamide: Calms redness and shrinks pore appearance

4.💧30 Days Of Wear

First swipe: feels like a cold stick of silk. Then it warms up and turns into a second-skin finish — not dewy, not matte. That weird perfect middle.

Week two I noticed my skin looked better without it. Less red, more even. That’s when I stopped caring about coverage and started caring about what it left behind.

💡

One Thing: Warm the stick on the back of your hand for 3 seconds before applying. Prevents that “too much product” streak look.

5.Honest Verdict

My pores looked smaller by week three — not dramatically, but noticeably. The glow stayed all day without getting greasy. But if you have oily skin, skip the T-zone application.

Buy if
You have normal-to-dry skin and want a 60-second face that looks like skin but better
⏭️

Skip if
You need full coverage or have very oily skin — this won’t hold up past lunch
💰

Worth it?
$54 for a 2-in-1 that replaces primer + foundation? Yeah, actually.

6.🔬Bottom Line

It’s not perfect — but it’s the closest I’ve found to a “my face but better” that also improves your skin over time. I’m on my second stick.

Where to Buy: Sephora or YSL direct. Grab the travel size first if you’re skeptical — $28, same formula.
