Questions fréquemment posées
What skin concerns is Effaclar Ultra-Concentrated Serum made for?
It’s formulated for adult acne-prone skin to reduce pimples, blackheads, enlarged pores, post-acne marks and improve skin radiance.
What are the key active ingredients and their functions?
It uses a tri-acid complex (1.5 % salicylic acid, 3.5 % glycolic acid, 0.45 % LHA) + niacinamide + thermal spring water to exfoliate, unclog pores, soothe irritation, refine texture and fade dark marks.
How should I use this serum in my skincare routine?
Apply once daily in the evening to cleansed skin (avoiding eye area), optionally follow with a moisturiser; always use sunscreen during the day.
How long until visible improvements are noticeable?
Clinical studies have shown reductions in pimples (≈ 45 %), blackheads (≈ 50 %), and marks (≈ 49 %) after about 4 weeks of regular nightly use.
Is the serum non-comedogenic and safe for sensitive skin?
Yes — the formula is non-comedogenic, tested on acne-prone skin, and includes soothing ingredients (niacinamide, thermal water) to help with tolerability.
Does this serum contain fragrance or alcohol, and what’s the texture?
It includes denatured alcohol and fragrance; the texture is light/gel-serum that absorbs quickly and is non-sticky/oily.
Can it be used together with other actives like retinoids or exfoliants?
Yes, but cautiously — alternate or reduce frequency if using strong exfoliants or retinoids to avoid over-irritation; monitor skin response. (Brand guidance implies sensitivity concerns)
What precautions should I take when using this product?
Avoid contact with eyes, do not apply to broken or irritated skin, patch-test first if sensitive, use sunscreen during daytime as acids increase sun sensitivity.
Is there a suitable routine or pairing with other Effaclar products?
Many users pair it with a gentle cleanser (e.g. Effaclar foaming gel), then follow with moisturiser; avoid over-washing and complement with SPF in morning.
What results can I expect beyond acne control?
In addition to blemish reduction, you can expect smoother skin texture, visible pore tightening, reduced dark spots, and improved overall radiance with regular use.
