Anai RUI Serum Review
Our verdict
Anai RUI packs two well-regarded actives, niacinamide and glycolic acid, into an affordable drop serum that may help with the look of uneven tone and surface texture across combination, dry, normal, and oily skin. At $14.79 the value case is strong, though shoppers new to glycolic acid should ease in gradually.

Overview
Anai RUI is a budget-friendly skincare brand with a no-frills approach to active ingredient delivery. This drop serum brings together niacinamide and glycolic acid, which is an uncommon pairing at this price point. Niacinamide targets the look of uneven tone and pores, while glycolic acid is an alpha hydroxy acid that may support a smoother-looking surface by helping with the appearance of dull, textured skin.
At $14.79 for 1.05 fl oz it is one of the most affordable dual-active serums available. The 4.4-star average from 266 reviews suggests buyers are getting genuine results, not just a low-cost formula that fails to deliver anything meaningful. The serum suits all four listed skin types: combination, dry, normal, and oily.
Because glycolic acid can cause sensitivity in those not accustomed to AHAs, new users should start with a few times per week rather than daily use and wear sunscreen during the day, as AHAs can increase photosensitivity.

Performance notes
Niacinamide, also known as vitamin B3, is used in skincare to target the look of enlarged pores, uneven skin tone, and surface dullness. Glycolic acid is a small-molecule AHA that may support a smoother surface appearance by helping the look of rough or textured skin. Together they address two related but distinct visible concerns. Glycolic acid also increases the skin's sensitivity to sunlight, so daily broad-spectrum SPF is essential when using this serum in a morning routine. Starting with two to three uses per week and building up is the standard approach for those new to exfoliating acids.
What buyers say
A 4.4-star average from 266 reviews is a reliable result for a serum under $15. The review volume is meaningful and suggests the actives are performing at a level buyers find noticeable. The price point likely draws shoppers who are skeptical at first, making sustained positive ratings more significant.

Frequently asked questions
Can I use niacinamide and glycolic acid together?
Yes, many serums combine them and most people tolerate the pairing well. Some research has noted that very high concentrations used together can cause temporary flushing, but at typical over-the-counter levels this is uncommon. If you notice redness or warmth after applying, scale back use to every other day.
Do I need sunscreen when using this serum?
Yes. Glycolic acid is an AHA that may increase your skin's sensitivity to UV exposure. This makes daily broad-spectrum sunscreen of SPF 30 or higher important when using this serum, particularly if you apply it in the morning. This applies to any product containing AHAs.
What does niacinamide do for aging skin?
Niacinamide, or vitamin B3, is often included in anti-aging formulas because it may support the look of even skin tone, minimize the appearance of pores, and help with the look of surface dullness. It is generally well tolerated across skin types and can be used alongside most other actives.
