The shelf life of a product after it has been opened is indicated by the Period-After-Opening (PAO) symbol, which represents the product's useful lifetime once opened.

On all Thuya Eye Products, you can find this PAO symbol, denoted as a number followed by 'M' (for months). For instance, a '12M' symbol means the product is best used within 12 months after opening.

All Thuya eye products are proudly cruelty-free. Thuya is committed to ethical practices and ensures that no animal testing is involved in the development of their products.

To obtain a complete list of ingredients for Thuya products, please refer directly to the product packaging or the tube, where all ingredients are conveniently listed. You can also find the ingredients under the product details section on our website.

Thuya's Permanent Gel and Neutralizer Cream are specially formulated to work with both Eyebrows and Eyelashes.

For your convenience, you can either use Thuya Permanent Gel and Neutralizer Cream from Thuya Brow Lamination Kit and purchase Thuya Lash Lifting Essentials, or opt for the separate Thuya Lash Lifting Kit, which includes all the necessary products for a successful Lash Lift.

The noticeable smell when Thuya Permanent Gel is applied is a normal part of the chemical process involved in the product's formulation.

Thuya does not add fragrances to their products, particularly because they are used around the delicate eye area. The absence of added fragrances is a conscious decision to minimize the risk of adverse reactions, especially for those with sensitive skin.

This commitment to safety and sensitivity may result in a stronger natural smell from the chemical process, which is typical and expected.

To open Thuya Permanent Gel, first remove the cap and security ring. Then, place the cap back on the tube to break the protective foil. Open the top part of the applicator to start using the product.

Tip: Remember to discard the first drop of the product closest to the tip of the applicator before each use.

If you’re pregnant or have recently given birth, we recommend checking with your healthcare provider before booking a brow or lash treatment. Hormonal changes during this time can affect hair texture and skin sensitivity, so it’s best to consult a healthcare professional to ensure the treatment is right for you.

If you’re using over-the-counter or prescription acne medications, it’s important to consult with your healthcare provider before getting a brow lamination or lash lift. These treatments involve chemical solutions that may not be suitable for sensitized skin. Always perform a patch test and seek professional medical advice if unsure.

Thuya Lash Lift results typically last up to 8 weeks, depending on your client’s natural lash growth cycle and how well aftercare is followed. For best results, we recommend using Thuya aftercare products to keep lashes healthy and nourished.
