All De:maf products undergo bacterial and microbial testing to ensure their safety.

Additionally, all cosmetics must contain preservatives to prevent deterioration. Likewise, De:maf uses the minimum amount of preservatives and antimicrobial agents that do not irritate the skin, keeping the risk of product deterioration as low as possible. While using higher amounts of powerful preservatives could prevent spoilage for several years, this can cause significant irritation and stress to the skin, which is something De:maf avoids.

Therefore, we recommend using our products within 6 months after opening to ensure maximum safety, especially when stored in a place away from direct sunlight.

Since oxidation begins as soon as the product is opened, it’s essential to pay attention to temperature changes. Avoid places with direct sunlight or high humidity and temperature fluctuations, like bathrooms.

It is best to store your products on a vanity in a cool, dark place away from sunlight. As for cleansers, shampoos, and body products that are often kept in bathrooms for convenience, we suggest keeping the bathroom well-ventilated and avoiding excessively hot showers to maintain a stable temperature as much as possible. 😊

De:maf products are formulated without ingredients that can cause allergies or irritate the skin as much as possible.

However, since everyone’s body, environment, and the current condition of their skin barrier and sensitivity are different, some people may find certain ingredients unsuitable for them.

For example, just as peanuts or peaches aren’t inherently bad but can cause allergies for some people, certain ingredients might not agree with your skin and immune system. We kindly ask for your understanding in this regard!

If you experience any allergic reactions, please stop using the product immediately. Don’t worry—we offer a full refund even for opened products.

In such cases, we recommend avoiding anything that could further irritate the skin for 3-4 weeks to help your skin barrier recover quickly. This includes exfoliation, brightening products, gua sha and massages, saunas, hot baths, direct sunlight, and outdoor activities.

If you experience breakouts after applying a specific product, it may not necessarily be due to an ingredient mismatch. The possible reasons could be:

1. Your skin barrier might be compromised, causing temporary hypersensitivity to new products.
When the skin barrier is weakened, trying new products can trigger breakouts or hypersensitive reactions!

2. It might not be the product at all—breakouts could coincide with your hormonal cycle (such as menstruation or ovulation).
