Liquid Gold

Most skincare brands are founded by marketers or chemists. 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.

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.

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.

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 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.

Formula

The Science

The 3:1:1 ceramide-to-cholesterol-to-fatty-acid ratio this product is built on comes from a body of work largely led by Peter Elias and Kenneth Feingold at UCSF through the 1990s and early 2000s. Their research showed that when the stratum corneum is disrupted, topical application of any single barrier lipid alone can actually delay recovery, while application of all three in physiologic ratios accelerates it. The specific ratio varies by experimental model, but 3:1:1 (ceramides:cholesterol:free fatty acids) emerged as a functional approximation for repair acceleration in several studies. Liquid Gold uses squalane as a well-tolerated fatty-acid analog, which isn't a literal free fatty acid but provides the emollient and lamellar-bilayer contribution the studies describe. The niacinamide in the formula reinforces this from a different angle: a well-known study in the British Journal of Dermatology (Tanno et al., 2000) demonstrated that topical niacinamide at 2–4% significantly increases keratinocyte ceramide synthesis and improves barrier function, which means you're simultaneously delivering lipids from the jar and telling the skin to make more of its own. Phytosphingosine, the fifth hero ingredient, sits upstream of ceramide biosynthesis as a sphingoid base, further supporting endogenous lipid production. What makes this combination unusual isn't any single ingredient — all of them appear in other products — but the fact that the formula is structured around the repair biology rather than around a single star active.

Dermatologist Perspective

Dermatologists frequently recommend ceramide-based moisturizers for patients with compromised barriers, eczema, or retinoid-induced irritation, and the specific concept of applying physiologic lipids in approximate natural ratios is well-supported in the dermatological literature. Board-certified dermatologists note that products formulated around the Elias barrier repair research are particularly useful for patients recovering from in-office procedures, aggressive prescription actives, or flares of dermatitis. While most dermatologist-recommended barrier creams come from legacy brands like CeraVe and La Roche-Posay, Stratia Liquid Gold has developed a reputation in the dermatology YouTube and Reddit communities as an indie that holds up to clinical scrutiny. It is commonly suggested as a moisturizer to layer over tretinoin at night, and as a first-line option for patients describing reactive skin after over-exfoliation.

Guidance

Founder Alli Reed started Stratia after dissecting skincare research papers as a frustrated consumer, and Liquid Gold was essentially her personal attempt to build the moisturizer the studies described. The name references the Elias lab's observation that the specific lipid ratio behaves like liquid crystal — self-organizing into functional barrier lamellae.

About Stratia Emerging Brand (2–5 years)

Stratia was founded in 2017 by self-taught formulator Alli Reed, who built the brand around peer-reviewed dermatological research. While the brand is young, its formulations are unusually well-referenced for an indie, and Liquid Gold specifically is built on the Peter Elias barrier-lipid studies from the 1990s–2000s.

Myth vs. Reality

Myth

A ceramide product is a ceramide product — Liquid Gold is no different from CeraVe.

Reality

CeraVe uses a similar concept but Liquid Gold uses all three of the Elias-studied ceramides (NP, AP, EOP) together with cholesterol and a fatty acid analog in an explicitly published ratio. CeraVe doesn't disclose its ratio.

Myth

You need something heavier than a lotion for serious barrier repair.

Reality

Barrier repair is about lipid composition, not thickness. A thin lotion that delivers the right lipids outperforms a heavy cream with the wrong ones.
