The first ingredient in a stick called Butter Up is not butter. It is isopropyl myristate, a light synthetic ester, and its presence at the top of the list explains the whole product. A stick made purely of cocoa butter and wax would be a candle — it would drag across cool skin and deposit almost nothing — and isopropyl myristate is the ingredient that turns four waxes and three plant butters into something that softens against the body and glides, leaving a glossy film behind. It is also, in the classic rabbit-ear comedogenicity studies, one of the more pore-clogging esters in common use, which is why the stick belongs on shins and elbows and not on a breakout-prone face or back. Understand that one ingredient and you understand Butter Up: a well-made solid balm whose format is its virtue and whose chemistry sets its limits.
The rest of the list is exactly what a solid body balm should be. Cocoa butter second and shea third are the occlusive bulk, cocoa's hardness holding the stick's shape while shea softens the glide; mango seed butter near the end adds a little more. Ozokerite, beeswax, carnauba and microcrystalline wax give it a structure that survives a handbag and a warm car. Isohexadecane adds a dry slip beside the ester. Sunflower oil brings linoleic acid, coconut oil melts quickly, and plum seed oil — the marketing hook — contributes a marzipan-sweet scent and a trace of vitamin E, with tocopherol beside it to keep the oils from going rancid. Then fragrance. There is no water, no glycerin or urea, and no active of any kind; it is fourteen ingredients of lipid and wax, which is honest.
In use it behaves as a balm stick should, with one learning curve. Swiped onto cool skin straight from the tube it drags and leaves little; pressed against the skin for a few seconds, or rubbed on a palm first, the waxes soften and it suddenly glides in a buttery, glossy stroke. On damp post-shower shins it spreads easily and leaves a visible sheen and a cushioned, slightly waxy film that feels heavier than a lotion for a few minutes and then settles; on elbows, knees and heels it sits as a sealing layer that holds for hours. The scent is sweet plum with a chocolate undertone from the cocoa butter, strong on application and lingering for an hour, which people either enjoy or find too much. A stick lasts three to five months of daily use on the usual rough spots, and far longer as a travel top-up, which is the use it was designed for.
What it will not do is anything a moisturiser does beyond occlusion. Without humectants it cannot draw water into the skin, so on truly dry skin it works best over a body lotion or on damp skin, sealing in water that is already there. It does not treat keratosis pilaris, eczema or anything else; the fragrance makes it a poor choice for reactive or eczema-prone skin, and the beeswax rules it out for strict vegans. The brand's claim that plum brings 'high vitamin C' to the skin is the kind of thing a budget brand writes on a stick: plum kernel oil is a fatty oil, not the fruit, and an anhydrous balm is no vehicle for ascorbic acid.
A word on where it sits in the brand's small body range, since the three products are easy to confuse. Formula 10.0.6 also sells a jarred body butter and a sheer dry-oil mist; the jar is the better buy for full-body moisturising at home, the mist for a quick all-over sheen, and this stick for the targeted, portable job — the elbow at a desk, the shins after a flight, the heels before socks. Buying the stick as a whole-body moisturiser is the most common way to be disappointed by it; it is a top-up, and it is a good one.
The evidence base is thin in the way body balms' usually are. Formula 10.0.6 has sold it since 2019, but only a few dozen Amazon ratings exist, at a middling 4.0 average, and the complaints are the predictable ones — hard to spread, waxy, strongly scented — while the praise is about the scent and the convenience. The occlusive chemistry of butters and waxes is well understood and needs no trial; the product's specific claims have none.
On price, eleven dollars on the brand's site is fair for a 70 g body stick and in line with the format; Amazon pricing is erratic and sometimes absurd, so buy direct or from a drugstore that stocks the line. For a portable balm that sits in a bag for months, the cost per use is low.
The verdict is modest and clear. For dry shins, elbows, knees and heels on normal-to-dry, non-reactive skin, and for anyone who wants a scented body balm they can apply in a car park without a jar or a wait, Butter Up is a pleasant, honest, well-formatted convenience at a drugstore price. For the face, chest or back, for breakout-prone or fragrance-sensitive skin, and for anyone expecting a stick to do the work of a moisturiser, it is the wrong tool — and the brand, to its credit, has never really claimed otherwise.
