Azelaic acid has become one of the most talked-about skincare ingredients of 2026—but not only because people are interested in what it may do for blemishes, redness and uneven-looking skin tone. Right now, the real conversation is about the chemistry. Two popular products—Anua’s Azelaic Acid 10 Hyaluron Redness Soothing Serum and Medicube’s Azelaic Acid 16 Calming Serum—have landed in the middle of a viral debate about pH, neutralization and whether azelaic acid still works

It’s July, which usually means market season is in full swing. For many indie makers, fairs, festivals, farmers markets, craft shows, pop-ups, and local events are not just “extra” selling opportunities. They are a major part of the year’s income. This is the season when products are being packed, labeled, displayed, sampled, purchased, gifted, and taken home by real customers. That makes this the right time to talk about something that is not as exciting as a new scent blend

I make skincare products. I teach other people how to make skincare products. I believe in handmade formulation, ingredient education, proper procedure, preservation, stability, testing, and understanding what we are actually making before we put products on our skin or into someone else’s hands. But there is a hard line. DIY sunscreen is where handmade skincare needs to stop. This is not me being anti-handmade, it’s literally what I’ve been doing for over 24 years. This is n

There is a big difference between making a product and formulating a product. And honestly, this is one of the most important conversations indie makers need to have before they start selling lotions, creams, serums, cleansers, micellar waters, gels, toners, or anything else that contains water. Because a lot of people use the word “formulating” when what they really mean is “following a recipe.” That is not meant as an insult. DIY making has value. It is how a lot of people

The words clean, natural, non-toxic, and chemical-free get thrown around constantly in the handmade skincare and soapmaking world. You see it in Facebook groups, social media comments, product descriptions, ingredient fear lists, and even from makers who are trying to sound more trustworthy to their customers. And I understand why it happens. People want safer products. They want to avoid unnecessary irritation. They want to feel confident about what they are putting on their

How supplier product names hide ingredient overlap, confuse inventory, and cost formulators money Cosmetic makers often buy the same raw material twice because suppliers sell identical INCI ingredients under different trade names. Here’s how to spot duplicates, compare suppliers correctly, and organize your inventory smarter. You do not always need more ingredients. Sometimes you just need to realize you already own them. One of the biggest mistakes beginning formulators make

If your formula “randomly” changes from batch to batch—viscosity swings, haze, weaker foam, unstable gels—water is a top suspect. Not because water is “bad,” but because different waters carry different types of impurities, and those impurities can push cosmetic systems around. A clean way to think about water quality (and one you can defend) is to sort impurities into four buckets: Physical stuff (suspended particles, sediment) Inorganic ions (minerals and salts like calcium

Melt & pour (MP) looks foolproof because you don’t handle lye and you don’t cure for weeks. But MP is also the fastest way to make soap that turns sweaty, soft, rubbery, cloudy, weak-lathering, or leaking oil? — because people treat it like a blank canvas. MP is finished, fully saponified soap that’s been engineered to melt and reset cleanly. Your job is to stop cooking it and stay inside the base’s additive budget . Myth Bust : “You can add whatever you want to MP.” No. M

The Only Science-Backed Blog You’ll Ever Need on pH, Actives, Ingredients, Preservation & the Truth About “Detox” Deodorant is one of the most misunderstood categories in skincare — especially in the DIY world. I spent months researching this information to share with all of you. Online “recipes” often rely on misinformation, unsafe ingredient usage, and completely made-up concepts like “armpit detoxing.” This confusion leads to burning, rashes, darkened underarms, breakouts,

Why “Always Pour the Smaller Phase into the Larger One” Isn’t a Rule Every so often, a formulation “rule” gets repeated so often that it starts being treated as a hard law of cosmetic chemistry — even when it isn’t one. One of those claims is the idea that, in an oil-in-water emulsion, you must always pour the oil phase into the water phase — especially if the water phase is larger — or the oil droplets won’t suspend properly. It sounds logical on the surface. It even sounds

The post every DIY skincare and soapmaking community desperately needs to read. There’s a conversation that comes up over and over again in maker groups, especially on Facebook. A maker follows a recipe—maybe something they found online, or even a professionally formulated recipe from a formulator they trust—and when their version doesn’t look, feel, or behave like the original, the frustration begins. They immediately want to know: “What did I do wrong?” “What did YOU do wro

A Mega Deep-Dive for Makers, Formulators, and Curious Skincare Lovers Welcome back to my blog, friends. In today’s post, we’re diving into something the internet desperately needs more of: science-based myth busting for cosmetic formulation. With TikTok tutorials, AI-generated “recipes,” and Pinterest skincare hacks circulating faster than ever, misinformation has become a real problem in the maker community. These myths don’t just ruin products — they create unsafe formulas,

The Hype Cycle of “Breakthrough” Ingredients Every few months, a new “miracle” ingredient lands in the cosmetic world, complete with glowing claims, glossy marketing and the promise of being the next big thing . You’ll see bold phrases like “clinically proven,” “patent-pending,” and “five times more effective than niacinamide.” The problem? Most of these ingredients launch before there’s any real data to back them up . Here’s how the cycle usually goes: A raw material suppl
