Xiaomi Derma DX700 and DX700S: What’s the difference and which model is better?

Xiaomi continues to expand its line of smart skin care devices, and its two latest innovations, the Derma DX700 and Derma DX700S laser epilators, have already sparked interest among users. At first glance, the models look almost identical: similar designs, similar promises of smooth skin without hairs, even the names differ only in one letter.

In this article, we will explore the key differences between the DX700 and DX700S, analyze their specifications, compare their performance and usability, learn whether to overpay for the model with the letter "S", what hidden nuances affect the result of hair removal, and which version is right for you - whether for home use or professional procedures.

We’ll focus on laser hair removal technologies that are used in these devices. Both models are marketed as safe and effective, but the difference in power, speed and additional features can play a crucial role. If you’re faced with the choice between the DX700 and DX700S, this article will help you avoid mistakes and make an informed purchase.

Specifications: under the hood comparison

So, to start with, the most important thing is that the technical parameters that directly affect the hair removal results, both of which use a diode laser with an 808 nm wavelength, which is optimal for hair removal on most skin types, but here the first differences begin.

Xiaomi Derma DX700 is equipped with a laser module with a power of up to 12 J / cm2, while the DX700S this figure is increased to 15 J / cm2. The difference in 3 J / cm2 may seem insignificant, but in practice it means:

• 🔹 Deeper laser penetration into the follicle of DX700S, which is especially important for hard or dark hair.
• 🔹 Reduced number of procedures: High power allows you to achieve visible results faster.
• 🔹 Higher cooling requirements, we’ll talk about that below.

Another key parameter is the flare rate: the DX700 has 1 Hz (1 flash per second) and the DX700S has 2 Hz. This means that it takes half as long to process one zone (like the legs), and for those who appreciate speed, this is a strong argument for the S model.

Finally, the cooling system. The DX700 uses air cooling with a fan, and the DX700S adds a semiconductor cooler (TEC) that reduces the temperature of the sapphire window to 5-10°C. This not only reduces discomfort, but also prevents burns on sensitive skin.

2. Design and ergonomics: convenience in hands

Both models are almost identical on the outside: a compact body with an ergonomic handle, touch buttons and a display for displaying modes.

📏 Dimensions and weight:

• 📦 DX700: 180 × 60 × 45 mm, weight 320 g.
• 📦 DX700S: 185 × 65 × 50 mm, weight 350 g.

The difference of 30 grams and a few millimeters may seem insignificant, but with prolonged use (for example, back treatment), the lighter DX700 will be less tedious.

🎨 Materials and assembly:

Both models have a metal body with a matte coating that is resistant to fingerprints, but the DX700S sapphire window (through which the laser passes) is larger by 10%, which allows you to capture a large area in one flash. Also in the model "S" added illumination treatment area (white LED), which facilitates work in poorly lit areas.

⚡ Nutrition and autonomy:

Both models are powered by a 220V network (no battery), but the DX700S comes with an improved power supply with voltage protection, which is important for regions with unstable power grids.

3. Operating modes and settings

The difference between the models is more noticeable here: the Xiaomi Derma DX700 offers 5 power levels (6 to 12 J/cm2), while the DX700S extends this range to 7 levels (5 to 15 J/cm2).

The DX700S’s main innovation is Skin Sense, which automatically detects skin tone and hair density to match the best settings, which is especially useful for beginners who are unsure about power levels. The DX700 doesn’t have that feature — you have to manually set the settings.

🔄 Additional modes:

• 🔄 Continuous mode: both models have it, but in DX700S it runs faster (thanks to 2Hz).
• ❄️ Cooling mode: DX700S can enable enhanced cooling before flare, which reduces pain.
• 👁️ Test mode: DX700S has added a low-power test flash function to check for skin reaction.

⚠️

Attention! In the DX700, when power is not chosen correctly (for example, 12 J/cm2 on dark skin), the risk of hyperpigmentation increases. DX700S with Skin Sense minimizes this probability.

Efficiency and results: What do the tests say?

According to independent tests (including reviews from GSMArena and XDA Developers), both models show high efficiency when used regularly.

📊 Comparison of results after 8 sessions (light skin, dark hair):

• 📉 DX700: 85-90% hair reduction.
• 📉 DX700S: 90–95% hair reduction.

The 5% difference may seem small, but in practice it means the DX700S handles fine and blonde hairs better than the base model.

⏱️ The speed of achievement:

Due to its higher power and flash frequency, the DX700S reduces total hair removal time by 30-40%.

• ⏳ DX700: ~40 minutes.
• ⏳ DX700S: ~25 minutes.

🩺 Safety and side effects:

Both models are FDA-certified for home use, but the DX700S has fewer complaints about:

• 🔥 Redness (thanks to better cooling)
• 😖 Soreness (due to precooling mode).

💡

Before the first procedure, be sure to test on a small area of skin (for example, on the hand), if within 24 hours there is no irritation, you can start a full hair removal.

5.Price and equipment: what do you get for the money?

At the time of publication (2026), the price difference between the models is ~30-40%. The exact prices depend on the region and the seller, but on average:

• 💰 Xiaomi Derma DX700: $250–$300.
• 💰 Xiaomi Derma DX700S: $350–$400.

📦 What's included?

💡 Should I overpay?

If your budget is tight, the DX700 is a great choice for basic hair removal, but if you plan to use it regularly and on large areas of skin (legs, back, hands), the DX700S will pay off by:

• ⏱️ Time savings (faster processing of zones).
• 🩹 Less discomfort (better cooling).
• 🔍 More precise setting (Skin Sense).

💡

If you choose between models, be skin type-oriented: for sensitive or dark skin, the DX700S will be safer due to automated settings.

6. Who is each model suitable for?

👩 Xiaomi Derma DX700 is perfect if you are:

👨 Xiaomi Derma DX700S is worth choosing if you:

⚠️

Both models are not recommended for very dark or tanned skin (Fitzpatrick IV-VI), or for the removal of light, gray or red hair, in which cases laser hair removal can be ineffective or even dangerous.

7. Alternatives: What do competitors offer?

Other laser epilators in this price segment should be considered before buying.

🔹 Braun Silk Expert Pro 5 (~$400):

🔹 Philips Lumea Prestige (~$500):

🔹 Tria Beauty 4X (~$450):

• ✅ Diode laser (like Xiaomi), but with a power of up to 22 J/cm2.
• ✅ Compact size.
• ❌ There is no built-in cooling.

📌 Conclusion: Xiaomi Derma DX700S offers the best value for money, especially when compared to Braun or Tria. A DX700 wins the competition in price while maintaining high build quality and efficiency.
