SONATAP 6-in-1 skincare device

SONATAP is designed to be compatible with almost any leave-on facial skincare product—including toner, essence, serum, ampoule, lotion, cream, and gel. The airless cartridges are made of PP (polypropylene) plastic with an external spring design, offering excellent chemical resistance and airtight protection to preserve formula integrity.

However, we do not recommend putting photosensitive formulas such as Tretinoin or pure L-ascorbic acid (Vitamin C) in SONATAP GEN-1, due to its translucent body. These formulas are best stored in opaque containers unless you keep the device in a fully light-blocking case.

Please note: while compatible, SONATAP is not intended to be used with wash-off or non-facial products like face washes, cleansers, makeup, hair and body care products.

While SONATAP’s cartridges are technically safe for storing sunscreen, we generally do not recommend it for the following practical reasons—but ultimately, it’s up to the user:

• Sunscreen is regulated as a drug, and proper protection requires a generous amount per use—a 12ml cartridge can provide only a few uses before refilling is needed. Unlike regular skincare products, complete coverage is essential for sunscreen to be effective, including harder-to-reach areas like the sides of the nose. Applying with a large applicator may still require follow-up with fingers, which reduces the convenience purpose.
• Some sunscreen formulas separate and require shaking before use—something that isn't possible once the product is decanted into the device.
• Many users consider sunscreen a “wash-off” or barrier product and prefer not to mix it with other leave-on skincare steps. In some cases, sunscreen doubles as a makeup-like finishing step, where application with fingers, a sponge, or a cushion is preferred for blending to achieve a desired finish. SONATAP’s non-porous silicone applicator is ultra-hygienic and suitable for skincare application, but it isn’t designed for makeup-style application.
  
  For these reasons, while technically compatible, sunscreen may not be the most practical use case for SONATAP.

Facial oils can technically be used in SONATAP, but there are a few important considerations:

• Oil residue is harder to clean and may require more frequent deep cleaning of the device and applicator.
• Oils have a higher chance of leakage, especially if the device is stored in warm environments or not cleaned regularly.
• Over time, oil buildup can affect the operation of the pump mechanism and may shorten the device’s cycle.

Absolutely. SONATAP’s total capacity is 72 ml—with six refillable tubes holding 12 ml each—which is well below the TSA limit of 100 ml per container.

In practice, our team has traveled internationally with SONATAP and never encountered any issues. As a precaution, we recommend removing the device from its case and placing it in the bin with your other liquids during security screening. This helps avoid unnecessary bag checks and ensures a smoother experience at airport security.
