AI summary of the Reddit excerpts below — not a quote

Salicylic acid serum is a staple recommendation for chemical exfoliation, particularly valued for managing acne, whiteheads, and sebaceous filaments. While generally effective, users emphasize that it can be drying or irritating, necessitating a cautious approach to frequency and product layering.

Pros

  • Effective for treating chin acne and minimizing the appearance of sebaceous filaments.
  • Functions as a reliable exfoliating step in a basic skincare routine.
  • Versatile application as a full-face serum, toner, or targeted spot treatment.
  • Widely available at an ideal 2% concentration across various brands.

Cons

  • Can cause significant redness and dryness, especially for those with sensitive skin.
  • May not be effective for all types of persistent or inflamed clogged pores.
  • Risk of over-exfoliation and skin barrier damage if used too frequently.

Caveats

  • Combining with other actives like glycolic acid or retinol can be 'intense' and may lead to irritation; some users suggest alternating nights.
  • Daily sunscreen use is considered mandatory when using this acid.
  • Sebaceous filaments are a normal skin feature and will likely return even with regular serum use.

Best for

  • Individuals with oily or acne-prone skin.
  • Those looking to target whiteheads and congested pores.
  • Users seeking a standard 2% BHA exfoliant.

Avoid if

  • You have highly reactive or naturally very dry skin.
  • Your current routine already includes multiple high-strength chemical exfoliants.

You've got some good products picked out, but I would add an exfoliating step like a salicylic acid serum.

why do you not use the salicylic acid serum every night instead of every other night? does it irritate your skin?
mixed · u/b****r · r/SkincareAddiction · comment · Jan 28, 2026 · open on Reddit ↗
Not serum specifically but I've used it before as a face wash 2-3 times a week

glycolic acid and salicylic acid in the same routine every night is pretty intense and could be making things worse instead of better. i'd scale it back to just one of those and give your skin a break bc sometimes less really is more, especially when your skin is already mad at you lol.

Use salycilic acid serum along with retinol and don’t forget to apply your sunscreen!

For the chin acne I would try using a salicylic acid serum product and see if it helps. Any brand is fine, I usually look for 2% salicylic acid serums.

I think it’s fine to use salicylic acid for your skin concerns. I would use it in your pm routine after cleansing and skip retinol that day

You could try a salicylic acid serum, toner, or spot treatment. Any brand is fine, 2% would be the ideal percentage

You could try oil cleansing them or using a salicylic acid serum or masque a couple of times a week, but if it's sebacious filaments they'll always return as they're part of normal healthy skin. All you can really do is minimise them
