Sweet things, pee cakes and headless dogs: 10 works of art worth seeing at Frieze

There's plenty at Regent's Park this year, from anti-depressant pens and a robotic Ibuprofen doll arm to a 26-year-old self-portrait of Miriam Kahn and a 150-million-year-old dinosaur skull - still with an embedded tooth - you'll find on Battleske's mid-platform review. British artist Ella Flack's installation vibrates under your feet with a man's voice. He whispers sweet nothings, and conjures up sexual fantasies

The raised platform in the middle of British artist Ella Flack's installation vibrates beneath your feet with a man's voice. He whispers sweet nothings, and conjures up sexual fantasies. It's all based on 3rd party agencies that manage OnlyFans accounts, interact with users, create fictional relationships that nerds pay thousands for. It's a greasy, unpleasant and disturbing exploration of sex work on an industrial scale.

Ioli Serfati's headless metal dog sculptures guard the pavilion, their claws sharp, their heavy udders dragging on the floor. It is a surreal symbol of femininity taken to extremes, a body devalued and exploited. A video shows the creature trying to escape from the stall and succeeding. The whole installation feels like HR Giger meets Wolfenstein 3D, but with a wicked, humorous edge.

Finally, something to help you get through Frieze. Thai artist Rirkrit Tiravanija's sculpture here is a robotic arm that carefully dispenses red and white ibuprofen pills to visitors. If you don't reach out, he just drops it on the floor. The bot will do its job over and over, regardless of whether you are there to receive it. It feels useless, ugly, repetitive, meaningless. Quite a comment on modern life.

It might look like a font display, and that's because it is. But each is a promotional item from a pharmaceutical company, given as a gift to American medical professionals. Lazard bought them at an estate sale from real doctors. Become a portrait of sales, how corporations buy health care in the United States. There are branded pens for anti-depressants, ADHD drugs, Viagra: companies keep you and keep you productive. When it clicks, it's an incredibly poignant conceptual view of how our bodies are treated as commodities.

Urine cakes in this year's Freeze Swamps aren't just to keep out the smell, they're art. This urinal cake is a sculptural intervention, thanks to artist Gray Wielebinski, who designed each one with a custom scent and enclosed them in metal cages. They kind of look like little cleaning supplies, glowing piles of smelly chemicals that you can cry over. They are strange and almost erotic sculptures. You can hear the mournful cries of thousands of artists who wish they had thought of it first.

There is so much (usually very bland) painting on the frieze that it really takes a special painter to make it stand out. But the installation of the Swiss artist Miriam Kahn is a perfect diamond among these hooks. It's a whole booth full of 26-year-old self-portraits. Each plumbs new depths of anxious and monstrous introspection. He grins and screams, stands and falls, all in blurry, messy colors. Extreme, excessive, emotional psychological issues.

William Adolphe Bouguereau in St. Pelle

My love for the 19th century French academic painter William Adolphe Bouguereau is on the brink of illness. I mean, I have a booger tattoo. So it was really exciting to find this little gem among the Dutch flower paintings and Egyptian busts of the frieze masters. It's a strange little yellow thing - based on a Tintoretto - a man lying prostrate on the floor. The ropes that bind him are torn, the wood is broken. Here is the aftermath of violence, the shocking silence after a traumatic event. That's one of the great things about masters: finding art historical gold hidden in the back wall of a booth. The gallery also had a beautiful portrait of James Tissot. This is the paradise of 19th century art.

There are fascinating narratives to discover in the Frieze Masters spotlight, particularly the work of Haitian modernist Luc Tournier, who lived between Paris and Haiti but has been largely forgotten by art history. This small show of gritty portraits – like a darker Alice Neal – and showcase is a glimpse into a lost period of international modernism from an artist who feels ready for a museum show.

Camarasaurus supremos skull at David Harron

You end up being blinded by Flemish art and antiquities walking around the frieze masters, so it's always a bit of Jurassic relief to find the fossilized dino skulls that David Aron Gallery has taken to the tent. This year they brought in a huge Triceratops skull and an awesome Camarasaurus supermus with Allosaurus teeth. Absolutely wild, and probably the only thing my four-year-old wants either way.

Death and fear are written here in all Sohrab Hora's paintings. They are gruesome expressionist scenes of everyday violence: a man kicking the ground, a crow pecking at a bleeding corpse above a face staring in wonder at a newspaper. It's like Edvard Munch, but with more blood and guts. The painting of the woman in the dust storm is not good, but the rest is great and angry.
