Liquid Gold

About Stratia

Stratia was founded by someone who got tired of reading research papers that described beautiful ideas and then going to Sephora to find none of those ideas had made it into a jar. Alli Reed started Stratia in 2017 as essentially a personal project — she’d dug deep into Peter Elias’s work on skin barrier lipids at UCSF, noticed that every paper kept pointing to a specific 3:1:1 ratio of ceramides to cholesterol to fatty acids as the composition the stratum corneum actually uses to rebuild itself, and realized that almost nothing on the market was formulated to match. Liquid Gold was her answer. That’s the origin story worth knowing, because it tells you exactly what kind of product this is: not a brief chasing a trend, but a literal attempt to translate a research paper into a lotion.

Formula

The formula is a study in discipline. Three skin-identical ceramides — NP, AP, and EOP — are paired with cholesterol and squalane (standing in for the fatty acid component) in a ratio that roughly mirrors intact stratum corneum lipids. Niacinamide sits around 4%, which is high enough to stimulate the skin’s own ceramide production, so you’re getting both exogenous lipids from the jar AND endogenous lipid synthesis from the active. Phytosphingosine adds another layer to that by acting as a ceramide precursor. The rest of the ingredient list is deliberately sparse: water, a gentle olive-derived emulsifier, a stabilizer, and a preservative system. No fragrance, no essential oils, no marketing-driven filler, no silicones doing cosmetic work. You can read the entire INCI list in under a minute and understand what every single thing is doing.

Texture

The texture surprises people who are expecting a heavy repair cream. Liquid Gold is a light, almost milky lotion that absorbs within a minute and leaves skin feeling cushioned but completely unburdened. It layers cleanly under sunscreen, and it layers even better over a retinoid — which is arguably its killer application. The same 3:1:1 ratio that the Elias lab studied was specifically researched in the context of barrier disruption recovery, and nothing disrupts a barrier quite like a nightly retinoid. Applying Liquid Gold over tretinoin or retinol is like handing your skin exactly the lipids it needs to rebuild, in exactly the proportions it would have synthesized them. Users with reactive, over-exfoliated, or actives-damaged skin frequently describe it as the first thing that worked when nothing else would.

Works for

It isn’t an occlusive. If you’re in Toronto in February and your cheeks are flaking off your face, Liquid Gold alone isn’t going to cut it — you’ll want a petrolatum-based cream or balm sealing it in at night. It also isn’t going to give you the plush slip of a luxury cream; it’s built for function, not indulgence. And at 50 ml, a bottle goes faster than a CeraVe tub, which is the main complaint you’ll see in any review. Stratia keeps the size intentional because the preservative system is minimal and they don’t want you working through a 200 ml jar of oxidized lipids for six months.

Value

Value is where this product quietly wins. At $30 for 50 ml you’re paying a premium over drugstore ceramide creams, but you’re also getting a formulation with published research behind every hero ingredient and a transparency about the why that you simply don’t get from La Roche-Posay or CeraVe. Those brands are excellent, and they have their own decades of clinical work. But Liquid Gold is doing something different — it’s treating barrier repair as a literal recipe from the dermatology literature, and delivering it without any of the decorative nonsense that usually gets bolted onto indie brand moisturizers. If you care about what’s in the jar and why, this is one of the clearest value propositions in skincare. If your skin is compromised, reactive, or wrecked by a winter of actives, there are very few moisturizers in this database that I’d put in front of it.
