## In short

Peter Ferrer's Delicious Mouth Spray is a sugar-free, alcohol-free oral spray with xylitol and oral probiotics, sold at Olive Young. Tried after meals and in the sluggish afternoon, the blueberry mint scent left only a gentle cooling sensation with no sharp menthol sting, and the reviewer's mint-loving kid liked it enough to carry it around in their own bag. A mouth spray worth trying for anyone who finds sharp minty sprays too harsh.

Ever notice how bad breath starts bothering you more the older you get?

I thought it was just me, but when I meet friends around my age, everyone quietly brings it up. Not long ago, my kid silently held out a mouth spray to me after a meal, and I was a little stung. Even if they didn't say anything, I couldn't help wondering if the smell had been bothering them — a mix of hurt feelings and worry. That's the day I started properly looking for a real mouth spray.

## Why bad breath worries us more as we age

When I think 'mouth spray,' I usually picture that sharp, biting mint scent. I'd only used products like that before, and every time I sprayed, I'd wince without meaning to. The harsh scent made me avoid using it altogether, which just made me worry about bad breath even more — a real vicious cycle.

Then I saw someone I know using a product and asked what it was — she said she'd bought it at Olive Young. That was Peter Ferrer's Delicious Mouth Spray.

## How I discovered Peter Ferrer's Delicious Mouth Spray

![Pitterpatter mouth spray two-scent lineup guide](https://img.superchart.com/images/pitterpatter-oral-spray-blueberry-mint/pitterpatter-oral-spray-blueberry-mint-08-sl2mz-900.webp)

The official brand name is Peter Ferrer, but a lot of posts I found while searching wrote it as 'Peter Letter.' I remember getting confused about the name myself at first and looking into it. That's also when I learned there are two scents — a peach-lychee blend and a blueberry-mint blend. At the store, I heard there's also an iced-tea flavored spray next to the peach line (exact lineups may vary by store, so it's worth checking in person). Now I'm curious about that one too. Since my kid loves mint so much, I went with the Delicious Mouth Spray in blueberry mint.

## Blueberry mint: how it actually feels to use

![Mouth spray tucked into a school uniform pants pocket](https://img.superchart.com/images/pitterpatter-oral-spray-blueberry-mint/pitterpatter-oral-spray-blueberry-mint-09-1l1rl-900.webp)
*Asked to take it in their uniform pants pocket, so I let them.*

The first thing that surprised me when it arrived was the size — small enough to fit neatly in one hand, easy to toss into a pocket or pouch.

My first impression was totally different from what I expected. I'm used to that sharp, spicy sensation, so I braced myself when I sprayed it — but there was no nose-stinging hit at all, just a soft, spreading freshness from the blueberry and a gentle minty coolness. No stickiness, just an immediately clean feeling in my mouth. I liked it after just one use.

The funny part came next. After I sprayed it once post-meal, my kid said 'me too!' and grabbed it — now they're planning to just carry it around in their own bag. I picked it to suit a mint-loving kid's taste, and now I'm the one getting it stolen from me.

*At an age where they're really conscious of bad breath, so they said they'd take it themselves~*

## What's in the ingredient list

![Mouth spray ingredient label information](https://img.superchart.com/images/pitterpatter-oral-spray-blueberry-mint/pitterpatter-oral-spray-blueberry-mint-11-1vltv-900.webp)

It's not just about the scent — I looked closely at the ingredients too. It contains xylitol at 3,000ppm and oral probiotics, and CPC (cetylpyridinium chloride) is listed as helping care for the bacteria that cause bad breath. It also contains bifidus fermented extract, which I found notable since it considers the balance of good bacteria in the mouth too. The product page also shows results from a bad-breath-causing bacteria test.

Maybe because it's sugar-free and alcohol-free, my mouth didn't feel as dry or sticky, right after spraying or even later on. I tend to get dry-mouthed by late afternoon, and I definitely noticed a difference there. It's passed Korea's Ministry of Food and Drug Safety certification, and being free of 7 harmful ingredients was reassuring in terms of safety, since it's safe to swallow.

## Why it's also known as an idol's go-to mouth spray

While looking into it, I found out this product is fairly well known as an idol's mouth spray. There was even a photo of a member of an idol group picking it directly, which explained why so many people around me kept recommending it. There was a reason it got that reputation. Since the scent isn't harsh, it seems like something you could use on stage or during a busy schedule without worry. Looking at other reviews, a lot of people mentioned that the alcohol smell isn't strong, which makes it comfortable to use, and that they keep it on hand because they like the sweet scent. I'd definitely recommend it to anyone who meets a lot of people for work.

## My own tips for using it

Here's a tip I picked up from using it myself.

- Rather than spraying right after coffee, rinse your mouth with a sip of water first — the freshness lasts much longer that way.
- Before heading out, keep it in a small pouch inside your bag so you can pull it out whenever you need it.
- Since my kid and I both use it, it might be worth each having your own.

## Frequently asked questions

### Can people who dislike minty scents still use this?

I'm someone who finds sharp minty scents overwhelming too, but blueberry mint has a gentle cooling feel, so I used it comfortably.

### Can kids use it too?

My kid uses it alongside me, and since it's labeled as using human-safe ingredients, I feel comfortable with that. That said, I'd recommend double-checking the exact age guidelines on the product detail page or with the retailer.

### How many times a day do you spray it?

I use it right after meals, and again in the afternoon whenever my mouth starts feeling a bit sticky.

### How long does the scent last?

It probably varies by person, but for me, one spray keeps that stickiness away for quite a long time.

## Wrapping up

If you've been looking for a softer scent instead of that sharp minty one, it might be worth trying the spray people call the 'Delicious Mouth Spray' yourself and seeing why. Though, like me, you should be prepared for your kid to steal it. The product that also shows up under searches for 'Peter Letter' is actually Peter Ferrer, and I've been having a satisfying time with it. You can find it at Olive Young.
