Mixing Week is your chance to create your own custom shade using Sistaco powders. Share your mix in the Sistaco Collective, and the top 10 most-loved mixes will be turned into real, official Sistaco shades.

Create your mix, take clear photos, and post it in the Sistaco Collective with all required details.

Your entry must include:

• A name for your mix
• The exact ratios used (all shades listed)
• Clear photos of your nails
• Your application method
• The correct hashtag: #MixingWeek

If any of this is missing, your entry may not be eligible.

Terms and Conditions

Selection of Winners: The top 10 mixes with the most likes by the closing date will be considered for production. Likes must be from unique, legitimate Facebook accounts. Any suspicious activity (e.g., use of bots or fake accounts) may result in disqualification. Sistaco reserves the right to make the final selection of winners at its sole discretion.

Colour Range: All mixes submitted must be created using shades currently available in the Sistaco range. Shades that are no longer part of the active collection will not be eligible.

Production Disclaimer: While Sistaco will make every reasonable effort to match the winning mixes, final product colours may vary due to production limitations. Sistaco does not guarantee an exact match to the submitted mix but will strive for the closest possible result.

Naming Rights: Winning mixes will be produced with the creator’s chosen shade name, subject to Sistaco’s final approval.

Production Timeline: Sistaco does not guarantee a specific launch date for the winning shades. Time is required to produce and prepare the Limited-Edition Collection, and timelines will depend on production and manufacturing factors. We appreciate your patience and understanding during this process.
