Protect at the surface. Nourish underneath.
Sunscreen and moisturizer are not the same job. One sits on your skin and deflects UV. The other works with your skin's own lipids to keep the barrier intact. Sky and Sol builds one product for each, from tallow and non-nano zinc instead of synthetic fillers. Here's what's actually in them and how I use them.
The Short Version (TL;DR)
Clean skincare, biologically compatible. Nutrient-dense ingredients, no synthetic fillers or harsh chemicals.
Built around grass-fed tallow and mineral, non-nano zinc oxide sun protection.
Designed to nourish, protect, and restore the barrier, function over marketing.
Inside: 60-day testing, ingredient breakdowns, reef-safe details, SPF comparisons, and honest buyer guides.
What Makes It Different
What makes Sky and Sol different
Conventional skincare formulations often lean on synthetic emollients, preservatives, and fillers that sit on the surface rather than working with the skin's own composition. Sky and Sol takes a different approach: skin-compatible fats like grass-fed tallow, mineral UV protection with zinc oxide, and simple formulations without unnecessary additives. Tallow's fatty acid profile is often compared to that of human skin lipids, which is part of why it's generally well tolerated, even by sensitive or dry skin.

Grass-fed lipids for the barrier
Zinc
Non-nano mineral protection
Formulation
Few ingredients, each with a job
The Distinction
What protects, and what nourishes
These are two different jobs. Mineral zinc sits on the surface and scatters UV light before it reaches your skin. Tallow works underneath, supporting the lipid barrier that already exists there. Switch modes to see each one on its own.
Conceptual mechanism diagram. Sunscreen and moisturizer act at different depths and do not perform the same biological function: one scatters UV at the surface, the other supports the skin's own lipid barrier underneath it.

Everything Cream review →My Take
Why I actually started wearing sunscreen
I don't really use a lot of sunscreen normally, but my dermatologist suggested I start, because of prolonged sun exposure. I spend a lot of time outside, whether that's by the pool, on a run, paddleboarding, or playing tennis, so I try to at least get my face and my shoulders covered as often as I can.
I'm not going to pretend I've been religious about it. I haven't. This is something I'm actively getting better at, and having a mineral formula that doesn't feel like a chemical sunscreen makes it a lot easier to actually reach for.

10% off · applies at checkout
Readers who want mineral sun protection and a barrier-support moisturizer without synthetic fillers, and who don't mind paying more for simpler ingredients.
The sunscreen leaves a light cast typical of mineral formulas; the Everything Cream is richer and sits closer to a balm than a lotion.
I keep the sunscreen by the door for exactly the days I listed above: pool, runs, paddleboard, tennis. The Everything Cream is what I actually reach for nightly. Neither replaces the other.
