What the evidence says
Mostly mechanism / observational
Most Borage Oil studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from high-quality meta-analyses and randomised trials published 1989–2021 with a typical study size of 1,596 participants.

In plain English: This Cochrane review of 27 trials concluded that oral borage oil and evening primrose oil lack effect on eczema, with improvement no better than placebo.
Bamford JT, Ray S, Musekiwa A, van Gool C, Humphreys R, Ernst E · Cochrane Database Syst Rev (2013)
In plain English: This Cochrane review found moderate evidence that GLA-containing oils — including borage, evening primrose, and blackcurrant seed oil — afford some benefit in relieving rheumatoid arthritis symptoms.
Cameron M, Gagnier JJ, Chrubasik S · Cochrane Database Syst Rev (2011)
22 studies included; 7 assessed GLA oils
GLA reduced pain intensity (MD -32.83 on a 100-point scale)
In plain English: Two months of borage oil consumption produced a statistically significant ~11% reduction in transepidermal water loss, indicating improved skin-barrier function in elderly people.
Brosche T, Platt D · Arch Gerontol Geriatr (2000)
29 healthy elderly participants, 360 or 720mg GLA/day for 2 months
Transepidermal water loss decreased ~10.8% (statistically significant)
Self-reported itch fell from 34% to 0%; dry skin reported less often
