What real users are saying
Buyer-review scan: 145,859+ verified Amazon reviews across 8 finalists.
- The Ordinary Niacinamide: Over 62,000 reviews, 4.7 stars — users repeatedly note fewer breakouts, reduced oiliness, and smoother texture. A small percentage report initial purging, but most see results within a month.
- The Ordinary Salicylic Acid: 12,000+ buyers praise its ability to clear blackheads and prevent pimples. Some note dryness, so pairing with a moisturizer is key.
- Anua Azelaic Serum: 5,600+ reviews highlight its redness-calming effect and lightweight hydration. Many switch from more expensive brands.
- Kate Somerville EradiKate: 2,691 reviewers confirm it dries out whiteheads fast, but the sulfur smell is consistently mentioned.
Across the category, consistency and patience are the common themes — most users see improvement after 6-8 weeks of daily use. Spot treatments work fast, but a daily active (niacinamide or salicylic acid) is the foundation for lasting clear skin.
Skip Harsh Scrubs
Physical exfoliants with walnut shells or gritty particles can tear at skin and worsen acne. Opt for chemical exfoliants like salicylic acid instead.
Avoid Fragrance-Heavy Serums
Fragrance and essential oils in leave-on products are common irritants for acne-prone skin. Always choose fragrance-free formulas.
Pass on Expensive Gimmicks
Products that promise miracle cures but lack clinically studied actives are usually a waste of money. For example, gold-infused or crystal serums offer no real acne benefits.
Don't Rely on Single-Ingredient Spot Treatments Alone
Using only a spot treatment without a daily active like niacinamide or salicylic acid won't prevent new breakouts. Build a routine around a proven serum.

Frequently Asked Questions
Is niacinamide good for acne?
Yes, niacinamide (vitamin B3) is excellent for acne. At 10%, it helps regulate oil production, reduces inflammation, and improves skin barrier function. Over 62,000 verified Amazon users rate The Ordinary's niacinamide serum 4.7 stars for its blemish-clearing power. Expect results in 4–8 weeks.
How often should I use salicylic acid?
Start with applying salicylic acid once daily (PM) after cleansing. If your skin tolerates it well after a few weeks, you can increase to twice daily. Overuse can cause dryness and peeling, so always follow with a good moisturizer. The Ordinary's 2% formula is gentle enough for most skin types.
Can I combine niacinamide with salicylic acid?
Yes, niacinamide and salicylic acid work well together. Salicylic acid exfoliates inside pores, while niacinamide calms skin and controls oil. Apply salicylic acid first, wait a few minutes, then layer niacinamide. If irritation occurs, use them on alternate days.
What is the best acne treatment for sensitive skin?
For sensitive, redness-prone skin, Anua's Azelaic Acid 10% Serum with hyaluronic acid is ideal. Azelaic acid gently exfoliates, reduces redness, and calms irritation, while hyaluronic acid hydrates. It's fragrance-free and has a 4.5-star rating from over 5,600 reviews.
How long before I see results with these treatments?
Most acne treatments require consistent use for 6–8 weeks to show marked improvement. Niacinamide and salicylic acid often begin clearing skin in 4 weeks. Retinoids like adapalene may take 8–12 weeks. Continue using even after clearing to maintain results.
Does The Ordinary Niacinamide serum work?
Across 62,132 verified reviews, buyers most often report fewer breakouts, reduced oiliness, and smoother texture. The Ordinary Niacinamide 10% + Zinc 1% boasts a 4.7-star average, making it one of the most effective and affordable acne serums. Some may experience mild purging initially, which should subside.
Is EradiKate worth the price?
At a mid-range price, EradiKate by Kate Somerville is a dermatologist-recommended spot treatment. Its 10% sulfur formula dries out pimples overnight for most people. Over 2,600 reviews give it 4.5 stars. It's worth the investment if you get occasional stubborn breakouts.
