I will have to agree with Dr Ethan and I think he has covered the questions quite comprehensively.
Personally, it is the risk of future scarring from prolonged, severe and deep seated inflammation from cystic acne that makes arresting and treating cystic acne quickly important.
In such an instance, steroid injections would definitely be one of my first line treatment options.
All the best!

Corticosteroid injections for cystic acne in Singapore costs about $50 – $200.
Cystic acne happens when the infection that causes acne goes deep into your skin, creating a large, inflamed, tender pimple that’s full of pus. These deep lesions are more likely to scar.
Steroid injections work by reducing the inflammatory reaction, and can potentially reduce the amount of damage/scarring caused by a large cystic acne.
Corticosteroid injections take about 4 – 8 hours to start shrinking the cystic acne. Pain will improve too. You’ll usually see the acne become flattened and less red within 24 hours.
Would you recommend a corticosteroid injection for cystic acne?
Let your doctor advise you on whether your cystic acne is appropriate to be injected, as there’s a small risk of skin depression/skin atrophy post injection, which usually resolves with time.
Will the acne return after the injection?
Yes, a corticosteroid injection treats only the pimple, but does not prevent acne from recurring at the same spot, or in other spots.
