I work here, so take the "pragmatic reviewer" hat with a grain of salt. But I also do the math before I recommend anything, and the math on these two bundles isn't identical — so here's the actual breakdown.
Short answer: Get Starting Point if you're new to Eau Eau or buying this as a gift — it pulls from all four of our lines, so there's no wrong pick. Get Formula Quatre if you've already tried us and know you lean toward Eau Complexe's original concepts or Mole•cu•lar's skin-close minimalism, and you want to go deeper in that lane instead of wider across all four.
Both bundles work the same way — pick any four eau de parfum, get 10% off. The difference is which four you're allowed to pick from, and that changes the math more than you'd think.
Starting Point vs Formula Quatre at a Glance
| Starting Point | Formula Quatre | |
|---|---|---|
| Eligible lines | Extrait, Absolu, Eau Complexe, Mole•cu•lar (all four) | Eau Complexe and Mole•cu•lar only |
| Bottle sizes | Mixed — 30 ml or 50 ml (Extrait, Absolu), 50 ml only (Eau Complexe, Mole•cu•lar) | 50 ml only |
| Total price (4 bottles, 10% off) | $115.20–$234, depending on picks | $158.40–$176.40, depending on picks |
| Typical price per bottle | ~$36.90 (one of each line) | ~$41.85 (2 Mole•cu•lar + 2 Eau Complexe) |
| Typical price per ml | ~$0.92/ml | ~$0.84/ml |
| Who it's for | Beginners, gift buyers, "I don't know what I like yet" | Repeat customers who already know their lane |
| Gift-worthiness | High — covers warm, fresh, bold, subtle | Lower — assumes the giftee already likes minimalist or conceptual scents |
A quick honesty note on that price-per-ml row: neither bundle has one fixed number, because you're choosing the contents. Formula Quatre stays tighter ($0.79–$0.88/ml) because every eligible bottle is the same 50 ml size. Starting Point can dip that low too if you stick to Mole•cu•lar and Eau Complexe within it, or climb to $1.17/ml if you load up on 50 ml Absolu. The numbers above assume realistic, representative picks for each bundle's actual purpose.
Eau Eau Starting Point: Built for People Who Don't Know What They Like Yet
Starting Point is the "just jump in" bundle. It draws from all four lines — Extrait, Absolu, Eau Complexe, Mole•cu•lar — so you can grab a warm gourmand Extrait, a maximum-strength Absolu, and a skin-close Mole•cu•lar in the same order and let your skin sort out the winner. That's genuinely the point: fragrance preference is personal enough that a spec sheet won't tell you what you'll reach for, and a $147-ish four-bottle spread across the whole spectrum is a cheap way to find out.
It's also the safer gift pick. You don't need to know whether your sister likes bold or subtle — Starting Point is built to hedge that bet across warm, fresh, bold, and subtle in one box.
Skip Starting Point if you've already been through a bottle or two and know your lane. Mixing a 30 ml Extrait with a 50 ml Absolu means you're paying Absolu-per-ml prices ($1.17) for two-thirds of your order, and that's a worse deal than just buying more of what you already know you like. Breadth is the whole value proposition here — if you don't need breadth, you're paying for it anyway.
Eau Eau Formula Quatre: For Going Deeper, Not Wider
Formula Quatre restricts you to Eau Complexe and Mole•cu•lar — our original-concept line and our single-molecule, close-to-skin line. Both sit at 15% concentration, so the difference between them is construction, not strength: Eau Complexe leans into fuller, richer compositions built around rare ingredients, while Mole•cu•lar is deliberately minimal, designed to layer under something else or wear alone as a near-invisible skin scent.
Because every eligible bottle is 50 ml, the math here is tighter and easier to reason about: $158.40 to $176.40 for four bottles, landing around $0.79 to $0.88 per ml depending on how you split between the two lines. That's a genuinely efficient way to build a rotation if — and this is the load-bearing "if" — you already know you like what's in this pool.
Skip Formula Quatre if you haven't tried a Mole•cu•lar scent yet and aren't sure about single-molecule, barely-there fragrance. Half the eligible pool is built to be subtle almost to the point of disappearing on some skin types, and if that's not your thing, you're picking from a shallow end of the pool. This bundle also locks out Extrait and Absolu entirely, so if what you actually want is our core ingredient-pair line or the maximum-strength option, this isn't the bundle — no matter how good the per-ml math looks.
Neither? Do This Instead
If four bottles feels like a commitment and you just want to try the brand, skip the bundles and buy one. Naked Molecule Eau Complexe is a reasonable single-bottle starting point — it's from the same "original concepts" line Formula Quatre draws from, at a single 50 ml bottle price with no bundle math required. If you'd rather start with our core line instead, pick one Extrait pairing that sounds like your kind of weird and start there.

FAQ
What's actually different between Starting Point and Formula Quatre? Starting Point lets you pick any four bottles across all four Eau Eau lines — Extrait, Absolu, Eau Complexe, and Mole•cu•lar. Formula Quatre restricts your four picks to just Eau Complexe and Mole•cu•lar.
Which bundle has the better price per ml? Formula Quatre is tighter and generally cheaper per ml — roughly $0.79 to $0.88 — because every eligible bottle is the same 50 ml size. Starting Point's per-ml cost swings more widely, from about $0.79 to $1.17, because it mixes 30 ml and 50 ml bottles across four different price tiers.
I don't know what I like yet — which one should I buy? Starting Point. It's built specifically for that situation, spanning warm, fresh, bold, and subtle across all four lines instead of narrowing you into two.
