What the gurus are saying

The 0.1% retinol here sits in the middle ground: gentle enough to pair with PDRN and peptides that buffer irritation, but not strong enough to satisfy those already seasoned with retinol. Those new to retinol find this a comfortable entry point that delivers firming benefits without harsh sensitivity. Anyone already using higher-strength retinol may find it feels like a step backward. Best used only at night, since retinol increases sun sensitivity.

"So if you're new to [azelaic acid or retinal], this is a great option. If like me, you're already established as a user of [azelaic acid and retinal], I think this would be a step back. [...] This is the 0.1% [retinal], so that's the equivalent of like the Geek and Gorgeous AAME 10 if you're doing a rough side-by-side comparison. Mid-strength, I would say. I'm glad I tried it. I think it's wonderful, but I think it's going to be situational as to how it works with you."

"I had a little bit of skin peeling with it, which is standard for me with any retinoid, but it didn't feel irritating or stingy at all, my barrier just seemed really happy. It's unfragranced, [...] lightweight and slightly creamy, [...] in a handy pump bottle, doesn't smell like too much, and it does have some clinical testing behind it, mostly with elasticity and pores. Overall I really enjoyed this product, and it made me a lot more open to trying out other PDRN products."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Retinoids

Retinoids are among the best studied ingredients in dermatology, with solid evidence for acne and for the fine lines and rough texture that come from sun exposure. Dryness and flaking in the first few weeks are common and usually settle.

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Ceramides

Ceramides are part of the skin's own barrier, and moisturisers built around them have evidence for holding water in and settling the tightness and flaking that come with a damaged barrier.
