Canada does not treat sun protection as cosmetics. The moment a product claims to protect skin from ultraviolet radiation, it leaves the Cosmetic Regulations and lands in one of two other systems — and which one it lands in is decided by the UV filters in the formula. Brands exporting from Korea routinely get this backwards. They assume the cosmetic notification that carried them into other markets will carry them into Canada, then discover the product cannot legally be sold under that framework at all. Two doors, and the filter chooses which one A sun protection product whose active ingredients…

Every brief for a long-wear lip product contains the same contradiction: it should survive a full day of coffee and conversation, and it should feel like nothing. Those two requirements pull on the same formulation dial in opposite directions, and the brief rarely says which one wins. Understanding the mechanism makes that conversation with a manufacturer much shorter. How the wear actually works A transfer-resistant liquid lipstick is a film deposited on the lip. The colour is suspended in a volatile solvent system — isododecane is the workhorse — carrying pigment and a film-forming polymer. The solvent flashes off within…
A regional institute went looking, and that is the story The Gyeongbuk Institute of Health and Environment ran safety testing on more than 100 mask pack samples pulled from department stores and roadshops, screening for heavy metals including lead, cadmium and nickel, along with methanol and dioxane. What makes this consequential is not the finding itself but who produced it. Provincial health institutes are not the national regulator. When one publishes contaminant testing on a consumer category, it tends to precede tighter attention from bodies that do have enforcement power — and it gives retailers a document to wave at…
The film is the product A silicone primer does one thing: it lays down a thin, continuous film that makeup can sit on. Dimethicone and its higher-molecular-weight relatives spread easily, dry to a slip finish, and bridge across pores and fine lines rather than sinking into them. Everything else on the label is secondary. That film also changes how pigment behaves. Powder applied to bare skin partly disappears into sebum and texture. Applied over a cured film, more of it stays on the surface, which reads as stronger colour payoff even though nothing about the eyeshadow has changed. Where formulators…
Volume is not something a shampoo adds. It’s something a shampoo avoids taking away. Fine hair looks flat because conditioning agents and residue coat the shaft and weigh it down, and the products that read as volumising are mostly the ones that deposit less, more selectively. That inversion is worth stating plainly, because it changes what a brief should ask for. The request “make it more volumising” usually translates, in the lab, into “remove things.” The formula is defined by what it leaves out Three levers do most of the work in a volume shampoo, and all three are subtractive.…
Most of the difficulty in this category is chemical rather than commercial. Pure L-ascorbic acid is the best-evidenced brightening active available to a cosmetic formulator, and it is also one of the least stable materials in the cabinet. It oxidises in water, browns in light, and loses activity across a shelf life that a brand has to guarantee for years. That single problem explains most of what a modern ingredient list looks like. When a pack says vitamin C, the material inside is frequently a derivative rather than ascorbic acid itself. The derivative trade 3-O-ethyl ascorbic acid is the one…
Brow products used to be an impulse add-on at the end of a colour range. They aren’t any more. Briefs that arrive at a manufacturer now specify hold strength, humidity performance and applicator geometry as separate requirements, which is the sign of a category consumers have started comparing before they buy. The three reference products buyers cite most often in these conversations are Anastasia Beverly Hills’ brow gel, Glossier’s Boy Brow and Benefit’s Gimme! Brow+. Useful shorthand, but they sit at different points on the hold-versus-volume trade, and a brief that names all three at once is describing three different…
A berry-toned multi-use stick is one of the cheapest ways for a young brand to look like it has a colour range. One mould, one shade family, two placement stories, and a product that photographs well on both zones. That commercial logic is why the format keeps reappearing in briefs. The development reality is less tidy. A product intended for lips and cheeks has to clear the stricter of the two rule sets on every input, and berry shades sit exactly where the pigment options get awkward. One SKU, two regulatory regimes Colour additives are approved by permitted use, not…
Zinc oxide and titanium dioxide are the two filters a brand can put on pack and legitimately call a physical block. That short list is the whole reason mineral sunscreen behaves the way it does as a development category. Both particles sit on the skin surface and scatter ultraviolet light instead of absorbing it, and every development headache that follows comes out of that one mechanism. The headache brands name first is the white cast. It is not a formulation flaw so much as physics doing exactly what it was asked to do: a white pigment that reflects UV also…
Two problems that look similar and behave differently Acne and rosacea both present as facial redness, and a lot of concealer briefs treat them as one target. They are not. Acne coverage is a spot problem: small, raised, high-contrast, and usually on skin that produces excess sebum. The formula has to sit on a bumpy surface without sliding off it, and it has to survive an oily base for several hours. Rosacea is a field problem: diffuse redness across the cheeks and central face, on skin that is reactive rather than oily. Spot-level opacity applied across a whole cheek reads…
