We launched a peptide night cream at Christmas. By spring we couldn't source the ingredients reliably. So we started over.
Not "how do we replace it" but "if we're rebuilding from scratch, what should the best unscented night cream actually be?"
That sent us deep into Japanese skincare research and a category called bioferments. La Mer built a brand worth hundreds of millions of dollars around one. SK-II built theirs around another. The science is real. Fermentation unlocks bioavailable peptides and amino acids that skin uses to repair overnight. It works.
What we kept coming back to: those ingredients have been available to formulators for years. The $200+ per ounce price tag isn't all science. A lot of it is the glass jar, the Sephora shelf space, and the retail margin chain between the manufacturer and your bathroom.
We skipped all of that. Here's what we built instead.
What bioferments actually are
Fermentation breaks down plant and marine ingredients into smaller molecules skin can absorb directly. The process also generates peptides that act as biological messengers, signaling skin to produce collagen, calm inflammation, and repair its barrier overnight.
La Mer's version starts with giant sea kelp. SK-II's starts with yeast from sake breweries. Ours starts with wakame seaweed. Different sources, same approach to the science.
What the premium brands charge
La Mer Rejuvenating Night Cream
$230 / oz at Sephora.
The good: Miracle Broth is a real, well-researched sea kelp ferment. The original luxury bioferment. Sensitive skin safe.
Worth knowing: No niacinamide. No vitamin C. Contains eucalyptus oil. A lot of that price is the weighted glass jar, the brand, and the retail shelf.
Genuine science, narrower formula than the price suggests.
SK-II
$150–$300+ per oz at Sephora and department stores.
The good: PITERA (yeast ferment) is real. Some products in their range include niacinamide. Strong on brightening.
Worth knowing: Contains added fragrance. Not for sensitive skin. Wide price range depending on product.
Solid ferment science. The price reflects a global luxury retail footprint.
Charlotte Tilbury Magic Night Cream
$145 for 1.6 oz (~$91 / oz) at Sephora, Ulta, Nordstrom, Target.
The good: Time-released retinol and stem cell extracts. Effective approach for its intended purpose.
Worth knowing: No bioferment. No niacinamide. No vitamin C. Contains fragrance. Not for sensitive skin.
When a skincare brand is at Target, the retail margin is in the price. Nothing wrong with that. Just worth knowing.
Ours
Silver Falls Bioferment Repair Cream. $26 / 1 oz. $58 / 3 oz.
Wakame seaweed bioferment. The same approach to skincare science La Mer pioneered.
Niacinamide (B3). Evens tone, fades dark spots. Most clinically validated brightening active in skincare.
Stable vitamin C (Sodium Ascorbyl Phosphate). Overnight brightening without sun sensitivity.
Centella + panthenol. Calm inflammation, rebuild the barrier.
Six cold-pressed oils. Hemp seed, evening primrose, avocado, raspberry seed, jojoba, grape seed.
No fragrance. Sensitive skin safe. Recyclable aluminum tin. Hand-poured in Oregon.
On the tin
Heavy glass costs more to make, more to ship, and more to dispose of. La Mer's jar has a weighted lid and a spatula. At $230 an ounce, the jar is part of the product.
Aluminum is infinitely recyclable and lighter to ship. What we don't spend on glass and retail shelf space goes into the formula. That's how we put a bioferment, niacinamide, vitamin C, centella, and six cold-pressed oils into a 3 oz tin for $58.
Not as pretty. Comfortable with that.
How they compare
La Mer, SK-II, and Charlotte Tilbury combined for space. Prices verified May 2026 at Sephora.
Different ingredients, same approach to the science. Both use marine fermentation to deliver peptides and repair compounds. La Mer uses giant sea kelp through their proprietary process. We use wakame through ours. The science is the same. The formulas are not.
We sell direct. No Sephora, no Ulta, no Amazon. The margin that would go to a retailer goes into the formula and the price.
Yes. No fragrance, no essential oils, no retinol. Centella and panthenol are specifically there for barrier repair and calming.
Nothing added. Faint natural scent from the cold-pressed oils and bioferment. Fades within a minute.
Couldn't source the key ingredients reliably. This is what came out of figuring out what to do next. We think it's better.
The formula is serious. The price isn't.
Wakame bioferment. Niacinamide. Stable vitamin C. Centella. Six cold-pressed oils. 1 oz for $26. 3 oz for $58. Hand-poured in Oregon.
