Your product starts in the lab.
Custom formulation for skincare and personal care brands. Our in-house lab develops your formula, proves it holds up, and hands you a manufacturing-ready product — without a single outside vendor.
Three ways to start your formula.
However far along your idea is, there's a starting point that fits. Most brands land on one of these three.
Start from scratch
You bring the idea, the target customer, and the price point. Our chemists build the formula from zero — texture, scent, performance, and stability designed around your brief.
Refine one of ours
Start from a proven base formula we already manufacture. Adjust actives, fragrance, viscosity, or feel until it's unmistakably yours — with far less time in the lab.
Benchmark a product
Bring a product you love — yours or a competitor's. We analyze it and develop a version that matches what you like, closes the gaps you don't, or improves on it outright.
From brief to production-ready, step by step.
A clear path, one team, and no lost handoffs. Here's what development with HWL actually looks like.
Discovery brief
We nail down the product type, claims you want to make, target cost, and packaging — so the lab work starts pointed at the right result.
Lab prototyping
Our chemists build first samples in-house and put them in your hands — not a spec sheet describing them.
Sampling & iteration
You test, we refine. Feel, scent, color, and performance are tuned round by round until you sign off.
Stress testing
Samples go through stability and packaging-compatibility checks, so the formula that wins in the lab still wins months later on the shelf.
Scale-up
The winning lab formula is translated to production batch sizes — same feel, same performance, at fill-line volumes.
Handoff to manufacturing
You get a manufacturing-ready formula with full documentation, per-unit costing, and a clear path into production.
Proven on paper, not just promised.
A formula isn't done when it feels good — it's done when it survives shipping, storage, and shelf time. We run the checks that back your claims up.
- Stability testing across temperature cycles
- Packaging & material compatibility checks
- Preservative system evaluation
- Ingredient & cosmetic-claim review
- Documentation for marketplaces, retail & international sales
Everything you need to start selling.
- A formula proven stable at production scale
- Complete documentation package
- Per-unit cost breakdown
- Packaging and fill specification
- A timeline for your first production run
