🦷 Differences between H, 7, 15, and 28 and how to choose in 2026

🎯 Why so many people are unsure how to choose vussen whitening toothpaste
『vussen（ビューセン）』 continues to sell out in the dental care section of Korean Olive Young.
The reason for its popularity is simple.
It is a whitening toothpaste developed by a famous Korean implant and dental care company.
Also, the numbers “H, 7, 15, and 28” in the product name indicate the concentration of the whitening ingredient.
Due to Japanese law, commercially available toothpastes in Japan cannot contain hydrogen peroxide, which whitens teeth from the inside.
However, some vussen lines contain ingredients used in dental whitening.
That is precisely why choosing a concentration suited to the condition of your teeth is so important.
🔢 What is the difference between vussen H, 7, 15, and 28?
vussen has four main product lines.
The numbers indicate the concentration. The types are broadly divided into “coating type (H)” and “whitening types (7, 15, and 28).”
✅ vussen H
Contains 5% hydroxyapatite, the main component of teeth. This type fills in surface damage and prevents discoloration. It is suitable for people with sensitive teeth and for maintenance care after whitening. When the YEPPURIKO editorial team tried it, we felt almost no irritation (individual impressions).
✅ vussen 7
A mild type containing 0.75% hydrogen peroxide. This line is often chosen as an introduction for people trying whitening toothpaste for the first time. Based on the editorial team’s experience, the irritation felt mild and it seemed easy to use every day (individual impressions).
✅ vussen 15
Contains 1.5% hydrogen peroxide. This mid-range option is chosen by people who drink coffee or tea every day and those who have begun to notice discoloration. Some people may occasionally feel a brief stinging sensation when using it (individual differences).
✅ vussen 28
Contains 2.8%, a concentration equivalent to that of an ingredient used in dental whitening, and is considered to provide the strongest whitening effect among the four lines (individual differences apply). It is the most popular option at Olive Young, but people with weak or sensitive teeth may experience sensitivity. This varies depending on the condition of your teeth.
🌞🌙 Why it is better to alternate between morning and night rather than use “28 only every day”
It may be tempting to think, “I should just use number 28, which makes teeth the whitest, every day,” but this is not the recommended way to use it.
A two-pronged morning-and-night routine has become a hot topic, especially on social media, among vussen users.
☀️ Morning care: vussen H
Use H for its coating effect in the morning. Protecting the surface of your teeth and keeping it smooth helps block stains caused by coffee and curry at lunch during the day.
🌙 Night care: vussen 15 or 28
Use the higher-concentration 15 or 28 at night, when you reset the day’s buildup. By brushing carefully and thoroughly, it targets and breaks down stubborn yellowing while you sleep.
Protect in the morning and target stains at night. The idea is to divide the roles to help achieve a visibly whiter smile while minimizing irritation.
💬 User experience and appeal as a souvenir
When the YEPPURIKO editorial team actually used it, we found the refreshing clean mint flavor and smooth lather pleasant. The user experience was no different from Japanese toothpaste (individual impressions).
It has less of the distinctive flavor often associated with overseas whitening products, making it easy to continue using every day.
The premium-looking packaging is another appealing feature.
It is chosen not only for personal use but also as a Korean souvenir. Mini sizes and toothbrush sets may also appear as special product offerings.

🩺 What to confirm in advance
The higher the number, the stronger the irritation, so if you have concerns about the condition of your teeth, it is recommended to start with a lower concentration without pushing yourself.
✅ These people should check with a dentist
If you have sensitive teeth, cavities or gum problems, are undergoing orthodontic treatment, or have crowns or dental bridges, a doctor’s judgment is required. The line you can use varies depending on your condition.

❓ Frequently Asked Questions
Q. What do the numbers in vussen represent?
A. They indicate the hydrogen peroxide concentration. 7 means 0.75%, 15 means 1.5%, and 28 means 2.8%. The higher the number, the stronger the whitening effect tends to feel, along with stronger irritation.
Q. Which should I try first, vussen H or 7?
A. If your teeth are prone to sensitivity or are sensitive, start with H. If you want to begin whitening gently, 7 is suitable as an introductory line.
Q. Is it okay to use vussen 28 every day?
A. Since it has the highest concentration, some people may experience irritation when using it continuously every day (individual differences). Using H in the morning and 15 or 28 at night has become a hot topic among users.
Q. Can I use it while undergoing orthodontic treatment or if I have crowns or dental bridges?
A. A doctor’s judgment is required. Since the line you can use varies depending on the condition of your teeth, be sure to consult a dentist before choosing.
