La Roche-Posay Effaclar A.I. Breakout Corrector 15ml
La Roche-Posay Effaclar A.I. (Anti-Imperfection) is a targeted spot treatment gel designed to reduce the appearance of individual blemishes, spots and breakouts quickly and effectively. It works on active spots while also helping to prevent the post-inflammatory marks and dark spots that blemishes frequently leave behind — making it a dual-action treatment for both active acne and its aftermath.
Part of La Roche-Posay's Effaclar dermatological acne range — one of the most recommended pharmacy skincare ranges for acne-prone skin in Ireland and Europe.
Key Ingredients & How They Work
- Salicylic acid — a BHA (beta hydroxy acid) that penetrates into the pore, dissolving the sebum and debris that block it and promoting cell turnover to clear the spot faster
- Niacinamide — reduces redness, soothes irritation around blemishes and helps prevent the dark marks (post-inflammatory hyperpigmentation) that spots leave behind
- Zinc pyrithione — antibacterial action against acne-causing bacteria (P. acnes) on the skin surface
Key Features
- Targeted spot corrector — apply directly to individual blemishes
- Works on active spots and helps prevent post-acne marks
- Fragrance-free and non-comedogenic
- Dermatologically tested on acne-prone sensitive skin
- 15ml — precise applicator for targeted use
- Part of the Effaclar dermatological acne range
- Available from Chemco Pharmacy — authorised La Roche-Posay stockist
How to Use
Apply a small amount directly to individual spots or blemishes once or twice daily. Can be used under makeup. Do not apply all over the face — this is a targeted spot treatment, not a general exfoliant. Use alongside a gentle daily cleanser and non-comedogenic moisturiser for best results. If using other exfoliating acids (AHAs, BHAs) in your routine, start with Effaclar A.I. on alternate days to assess tolerance.
For external use only. Avoid contact with eyes. Salicylic acid may increase sun sensitivity — use SPF during daytime. Not recommended during pregnancy. Patch test before first use. Always read the label before use.
Frequently Asked Questions
How quickly does La Roche-Posay Effaclar A.I. work on spots?
Most users notice visible reduction in spot size and redness within 24–48 hours of application. The salicylic acid acts quickly to exfoliate the blocked pore and the zinc pyrithione targets surface bacteria rapidly. Niacinamide begins to reduce redness almost immediately. For best results apply at the first sign of a spot forming — the earlier in the spot's lifecycle it is applied, the faster the response.
Can I use Effaclar A.I. on the whole face?
No — it is formulated as a targeted spot treatment for use on individual blemishes only, not as an all-over facial treatment. Applying it across the full face increases the risk of dryness, irritation and skin barrier disruption. For daily all-over acne management, use the Effaclar Purifying Foaming Gel or Effaclar Mat moisturiser from the same range alongside this targeted corrector.
Will Effaclar A.I. prevent acne scars?
The niacinamide in Effaclar A.I. specifically targets post-inflammatory hyperpigmentation — the dark or red marks that spots leave behind as they heal. Applied promptly to a spot, it can meaningfully reduce the severity of the mark left after healing. However, it does not treat established acne scarring (indented or pitted scars) — these require dermatological intervention.
