See a current list of Sistaco shades HERE

Are there limits on how many shades I can use in a mix?

Yes. There is a limit on how many shades can be used in one mix to ensure it can be realistically produced.

No more than four shades in one mix will be considered.

Overly complex mixes may not be eligible.

Where do I post my entry?

All entries must be posted in the Sistaco Collective Facebook Group. Entries posted anywhere else will not be counted.

How are winners chosen?

Winners are based on the number of likes on their post. The top 10 mixes with the most likes by the end of the voting period will be selected.

Will my mix look exactly the same when produced?

Not always. Sistaco will aim to match your mix as closely as possible, but slight variations may happen during production.

Can Sistaco change or remove entries?

Sistaco reserves the right to review all entries and make final decisions regarding eligibility and selection.

Where can I find the full Terms & Conditions?

Right here!

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.
