If you google "natural acne treatment" it will usually not take long until you find a reference to fish oil and gamma linoleic acid (as in borage or starflower oil). Against that background it is surprising that the Korean scientist are obviously the first to scrutinize the efficacy of 2,000 mg of eicosapentaenoic acid and docosahexaenoic acid and 400 mg γ-linoleic acid (from borage oil) in a parallel design dietary intervention study.
Long-standing "natural acne cure" now scientifically proven
The 45 participants with mild to moderate acne, were allocated to either of the intervention groups for 10 weeks, after which the effect on their skin was evaluated visually and via heamatoxylin, eosin and immunohistochemical staining of the lesions.
DHA + EPA vs. GLA + X: I am not sure if this may have skewed the results, but it is imho worth mentioning that the DHA + EPA group received their 2g of long-chain omega-3s in form of two caps of pure EPA + DHA. The GLA group, on the other hand, had to take 2 caps with 1,000mg of borage oil, which contains 200mg GLA per gram, but also up to 420mg of "regular" linoleic acid, of which scientists believe that it is an acne vulgaris promoter (Wolf. 2004).And what the scientists observed was ... positive, at least in the omega-3 group, the mean inflammatory acne lesion count was significantly reduced (from 10.1 ± 3.2 in week 0 to 5.8 ± 3.4 in week 10; p < 0.05).

In the end, there was no no significant difference between the two treatments for any of the measured parameters, so that it is probably up to you, whether you try to control the "fire within your skin" with GLA or DHA + EPA supplements.
"Mean non-inflammatory acne lesion counts were also reduced by omega-3 and GLA supplementation (23.5 ± 9.2 to 18.9 ± 8.3, p < 0.05, and 22.8 ± 8.4 to 19.2 ± 7.2, p < 0.05, respectively) at final visits, whereas mean lesion count in the control group was unchanged (from 21.8 ± 9.7 to 22.0 ± 8.6). Significant differences were evident between the treatment groups and the control group after 10 weeks (p < 0.05)." (Jung. 2014)
