Anua Peach 70 Niacin Serum

⏱ 2 min read
Quick answer: Peach 70 Niacin Serum is Anua's serum, built around Niacinamide (B3). Normal, combination and mildly dry skin that wants a comfortable everyday niacinamide rather than a clinical one.

A niacinamide serum in a peach extract base, following the same naming convention the brand uses across its range: the big number counts the botanical extract, not the active. The texture is light and slightly milky with a soft peach scent, and the whole thing is engineered around feel as much as function. Niacinamide is the ingredient with the actual evidence behind it, sensibly supported for the appearance of tone, texture and pore visibility.

What it is built around

🧫 Niacinamide (B3)

Who it suits

Normal, combination and mildly dry skin that wants a comfortable everyday niacinamide rather than a clinical one. Good for the look of dullness and rough texture. People who flush from niacinamide will flush from this too. If you dislike scented skincare, the peach note is noticeable enough to be a dealbreaker, and fragrance-free niacinamide serums are easy to find.

How to use it

After toner, before moisturiser, once or twice a day. Two or three drops is enough for the whole face. It layers under sunscreen without pilling, which is not true of every serum at this price. If you also use a high-strength ascorbic acid, put them at opposite ends of the day rather than stacking them.

⚠️ Worth knowing: The number in the name is a marketing convention, not a potency claim — a high percentage of fruit extract is mostly water with fruit in it, and it tells you nothing about how much niacinamide is present. The peach scent is pronounced. And niacinamide, while well supported, works slowly and subtly; anyone expecting a visible change in a fortnight will be disappointed.

What is the difference between essence and serum?

In Korean skincare, essence is typically a thinner, hydration-focused layer that preps skin, while serum is more concentrated with targeted actives like vitamin C or niacinamide. Essence usually comes first; serum follows. The line between them blurs, and not every routine needs both.

What is the difference between essence, serum and ampoule?

Essence is the lightest and most hydration-focused, serum is more concentrated and targeted, and ampoule is the most concentrated of the three. The boundaries are marketing convention, not regulated definitions.
