You can buy Haus Labs by Lady Gaga products primarily through two official channels:

• The official Haus Labs website at hauslabs.com, where you can find the full product range and current promotions

• Sephora stores and Sephora's online shops in the US, Canada, UK, and across Europe. Haus Labs is an exclusive retail partner of Sephora

In some countries like Germany, Haus Labs products are not available in local stores but can be conveniently ordered from the official online shop, although some Sephora sites may not ship internationally (e.g., Sephora UK does not ship to Germany)

. Additionally, some department stores like Manor in Switzerland also carry Haus Labs products online

. To summarize, your best options to purchase Haus Labs are:

• Online at hauslabs.com (direct from the brand)
• Sephora (in-store or online in supported countries)
• Selected department stores like Manor (depending on your location)

Avoid unauthorized sellers, as Haus Labs products are only authorized for sale through these official channels
