You heard right — they nuked the silicone and messed with the pH. I’m 30 days into the new SkinCeuticals Silymarin CF and my chin is the witness.
It’s not the same serum. It’s stickier, feels tighter on application, and the old “glide” is gone. But here’s the kicker — my breakouts are smaller and heal twice as fast.
This is a $182 antioxidant serum that claims to fight acne and oil. The reformulation swapped dimethicone for a water-thin base and dropped the pH to 2.9—aggressively low.
No Silicone
It absorbs in 8 seconds flat, zero slip, but leaves a matte film that makes your skin squeak.
Lower pH
That’s the acid mantle zone—it stings for 3 seconds if you have any micro-cuts. Then it stops.
Antioxidant Stack
Still 15% vitamin C, but the ferulic acid ratio feels more aggressive on bare skin.

Don’t let the “silymarin” fool you—it’s the milk thistle extract that calms redness, but the real workhorse here is the low pH. It exfoliates while it protects.
- Silymarin: Dries out active spots without flaking
- 15% L-ascorbic acid: Brightens but now penetrates deeper
- Ferulic acid: Stabilizes the C, but feels spicier
- Hyaluronic acid: Barely there—you’ll need your own moisturizer

Day one: it felt like applying thin, watery vinegar with a hint of orange peel. My face looked greasy for 5 minutes, then bone-dry.
Week two blew my mind—the old version made me oily by noon. This new one? My T-zone stayed matte until 4pm. By week three, the deep cystic bumps on my jaw flattened. They didn’t disappear—they just… deflated.

My blackheads didn’t vanish, but the angry red inflammation did. Oil control is the real win—it’s like blotting paper in a bottle.

The reformulation made it better for oily skin, worse for dry/combo. It’s a trade-off, and for me, the breakouts lost.
