e.l.f. Blemish Breakthrough Triple-Acid Resurfacing Night Serum — 10% Niacinamide, Fragrance-Free Vegan

e.l.f. SKIN Blemish Breakthrough Triple-Acid Resurfacing Serum is an overnight, dermatologist-developed serum that blends salicylic acid, tranexamic acid, and PHA with 10% niacinamide to exfoliate, soothe, and improve post-breakout skin texture and tone.

This lightweight night serum targets congested pores and visible post-breakout marks while delivering hydration. Formulated by dermatologists and non-comedogenic, the serum uses an 8.5% triple-acid complex plus a high concentration of niacinamide to help resurface skin gently as you sleep. Fragrance-free and vegan, it’s designed for oily and acne-prone skin types seeking clearer, smoother results without harsh irritation.

How does the triple-acid complex work on blemishes?

The three-acid blend combines different exfoliating and clarifying actions: salicylic acid penetrates pores to loosen debris, PHA provides gentle surface exfoliation that helps reduce irritation, and tranexamic acid targets uneven tone and post-breakout discoloration. Together they support a clearer appearance without over-stripping skin.

• Salicylic Acid: oil-soluble BHA to unclog pores
• PHA: gentle exfoliant that preserves moisture
• Tranexamic Acid: helps fade hyperpigmentation
• 8.5% total triple-acid concentration for measurable resurfacing

Will this serum dry out or irritate my skin?

The formula balances active acids with 10% niacinamide to calm redness, regulate excess oil, and support the skin barrier. Because it’s fragrance-free and non-comedogenic, many users find it tolerable overnight; if you experience sensitivity, reduce frequency to every other night.

• 10% Niacinamide soothes and helps control oil
• Fragrance-free to minimize irritation risk
• Non-comedogenic and dermatologist-developed
• Use 3–5 drops nightly, alternate nights if needed

How do I add this serum into my evening routine?

Apply the serum after cleansing and before any heavier creams or oils, using 3–5 drops to cover the face and neck. Allow it to absorb fully and follow with a moisturizer to lock in hydration; avoid mixing with other strong actives until you confirm tolerance.

• Step 1: Cleanse and dry skin
• Step 2: Apply 3–5 drops of serum evenly
• Step 3: Wait a minute, then apply moisturizer
• Tip: Start with alternate-night use if you’re new to acids

How soon can I expect to see improvements?

Individual responses vary, but many users notice reduced congestion and smoother texture within a few uses, with more visible tone improvements over several weeks. Consistent nighttime use, combined with sunscreen during the day, helps protect results and prevents further post-breakout darkening.

• Immediate: lighter smoothing and pore clarity for some users
• 2–4 weeks: clearer texture and fewer active breakouts
• 4+ weeks: improved tone and fading of post-breakout marks
• Use daily or every other night based on sensitivity

Who is this for: This serum is intended for people with oily, acne-prone, or congested skin who want a targeted overnight treatment that resurfaces and evens tone without heavy drying. It’s a good option if you’re seeking a dermatologist-developed, fragrance-free formula with high-strength niacinamide and a multi-acid approach. Avoid if you have known sensitivity to BHA, PHA, or niacinamide, and consult a dermatologist for use alongside prescription treatments.
