 In My Skin focuses on Welsh teenager Bethan who is trying to live a double life as she negotiates her mother's mental illness, friendships and her sexuality. Her mother has bipolar disorder, and is sectioned in a psychiatric ward. Bethan dreams of being a writer, but attends a hostile and homophobic school.
 In My Skin was initially ordered as a short film for BBC Wales, which was filmed across five days. This later acted as the pilot episode when BBC Three ordered In My Skin as a full series. Produced by Expectation Entertainment, it acts as the company's first scripted commission. Creator and writer Kayleigh Llewellyn stated that her draft for the series was "warmly received" by the BBC, and director Lucy Forbes joined the project due to "the power of the subject matter". Llewellyn explained that she and casting director Rachel Sheridan were focused on having local Welsh actors appear in the series, as they could bring the "characters to life". The series is filmed in Cardiff, Wales. The first series was, according to Llewellyn, "written in five weeks, shot in five weeks and shot on a budget of £500." In March 2021, BBC renewed In My Skin for a second and final series. Llewellyn stated that she was excited to "finish telling Bethan's story", and that in the writing process she was "oscillating between laughing uproariously and ugly crying". Molly Manners was chosen to direct the second series, with Llewellyn voicing her excitement at Manners' involvement. Filming for the second series commenced on 29 March 2021 in Cardiff. Filming wrapped on 1 May 2021. The second series premiered on 7 November 2021.
 For the first series, the review aggregator website Rotten Tomatoes reported a 100% approval rating with an average rating of 7.2/10, based on 13 critic reviews. Metacritic, which uses a weighted average, assigned a score of 78 out of 100 based on 8 critics, indicating "generally favorable reviews".
 Rhiannon Lucy Cosslett of The Guardian described In My Skin as "an emotional rollercoaster of a TV drama", writing that it is " a series of huge emotional heft, and an extraordinary achievement by writer Kayleigh Llewellyn, who surely has huge things ahead of her". The Sunday Times listed the series as a "critics' choice", writing that it is a "mesmerising drama", adding that Creevy and Hartley's performances were "remarkable". Annie Lord, writing for The Independent, described In My Skin as a "hilariously dark coming-of-age drama [that] cuts deep", and that "Llewellyn's dialogue is caustic and sharp". Time listed it as one of the best five television series of July 2020. Time wrote: "A combination of black humor, raw depictions of trauma and authentic performances mark the series as part of the same wave of British TV that includes auteurs like Phoebe Waller-Bridge and Michaela Coel. Llewellyn may not be the public face of her show, the way those women are, but she too is speaking from the heart—and her message resonates". In November 2021, the second series of this Welsh comedy drama would receive 5 stars in Rebecca Nicholson's Guardian TV review, stating that it is "a poignant must-see which deserves widespread acclaim".
