It's tempting to read '107 Beauty retinal serum with a Vinbiome fermentation complex' as a gimmick-first product — a trendy retinoid dressed up in the brand's vinegar-and-ferment story. But the ingredient list tells a more serious tale. At the heart of this serum is 0.1% retinal — retinaldehyde at 1000ppm — and that's not a token, beginner-friendly trace. Retinal is the retinoid that sits one conversion step from active retinoic acid, making it more efficient and faster-acting than retinol, and 0.1% is a genuinely potent, results-grade dose. This is a real retinoid serum, and the fermentation theme, as we'll see, is the supporting cast rather than the star.
The retinal is what does the work, and 0.1% is enough to deliver meaningful results: over 8 to 12 weeks of consistent use, you can expect refined texture, smaller-looking pores, softened fine lines, and more even tone — the genuine retinoid payoff, not the subtle nudge of a gentle starter formula. For someone with some retinoid experience who wants a potent, efficient retinal without jumping to prescription tretinoin, this is a legitimately strong option. Niacinamide sits ninth, high enough to add brightening and barrier support while helping buffer the retinal, and the formula is fragrance-free, which is the right call for a potent active.
Where 107's identity genuinely earns its place is in the buffering. A bare 0.1% retinal would be a recipe for retinization misery, but this serum cushions it thoughtfully: ceramide NP and squalane for barrier lipids, the 'Vinbiome' ferment complex (lactobacillus, bifida, lactococcus, streptococcus thermophilus) plus prebiotics and aged vinegar for conditioning, bisabolol, panthenol, allantoin, and centella for soothing, multiple HA forms and a rice-bran-water base for hydration, and antioxidant botanicals (terminalia/haritaki, schisandra, perilla, green tea, ginseng) for support. That's an unusually deep cushioning system, and it makes the serum more tolerable than its strength would suggest — the fermentation theme, in other words, isn't just marketing here; it's doing real supportive work alongside the retinal.
The honest framing has to be clear about two things. First, 'well-buffered' is not 'irritation-proof.' At 0.1% retinal, some dryness, flaking, or purging is still possible in the first few weeks as your skin adjusts, even with all that soothing support. It's not a beginner's retinoid you can slather on nightly from day one — start two or three nights a week, build up slowly, buffer with moisturizer if needed, and don't stack it with other retinoids or acids the same night. Genuinely reactive, rosacea-prone, or barrier-compromised skin may still find 0.1% retinal too strong regardless of the cushioning. Second, the non-negotiable: it contains a retinoid, so it is not pregnancy-safe — retinal is advised against in pregnancy and breastfeeding, and the soothing buffering changes nothing about that.
A couple more fit notes: it's not fungal-acne safe (caprylic/capric triglyceride, isoamyl laurate, olivate emulsifiers, lecithin), and it contains hydrolyzed wheat extract, a non-issue for almost everyone but worth flagging for the wheat- or gluten-sensitive. Reassuringly, it's vegan and fragrance-free, and the opaque packaging is appropriate for light-sensitive retinal.
The sticking point is value. At fifty-four dollars for 30ml, this is a premium price — high even for a well-formulated 0.1% retinal, and notably steep coming from an emerging indie brand. You're paying for a genuinely sophisticated, deeply buffered, fragrance-free retinal with a thoughtful ferment-and-antioxidant supporting cast, which is real quality — but there are effective 0.1% retinal serums from more established brands at lower prices, even if fewer match this one's cushioning. Whether the premium is worth it depends on how much you value the buffering, the fragrance-free formula, and the brand's distinctive concept.
It's worth situating this in the retinoid landscape, because 0.1% retinal is a specific, intermediate-to-advanced strength. Beginners should start gentler (a lower-dose retinal or an HPR product) and work up; seasoned tretinoin users may find it a step down. This serum sits in the sweet spot for someone who's used a mild retinoid, tolerated it, and wants to step up to a genuinely effective dose — with the unusual bonus that the deep buffering makes that step less punishing than a bare 0.1% retinal would be.
The fermentation theme, which could easily be a gimmick, here actually serves the formula: a potent retinoid benefits from soothing, barrier-supportive company, and the ferments, ceramide, and botanicals provide exactly that. So while you're buying this for the retinal, the Vinbiome buffering is the thing that makes a strong dose livable for more people — a case where the brand's identity and the product's needs genuinely align.
As an emerging brand with a still-building review base, 107's track record here is shorter than legacy names, so the score leans partly on the soundness of the formula — but the formula is genuinely sophisticated, and early feedback praises both the results and the tolerability. So the recommendation is clear-eyed and warm: if you have some retinoid experience, want a potent 0.1% retinal that's unusually well-cushioned and fragrance-free, and the premium price doesn't deter you, this is a genuinely good, results-oriented serum — buy it for the retinal, and appreciate the Vinbiome buffering as the thing that makes a strong dose livable. If you're a retinoid beginner, pregnant, fungal-acne-prone, or budget-conscious, look to a gentler, cheaper, or non-retinoid option instead.
