What's New

The Dancing Duo is part of BUXOM's 2026 Holiday lineup. The brand describes it as "the perfect everyday lip combo." Both products are full size, and the packaging labels the set a Plumping Lip Kit. Neither product is new to the range. The kit pairs two existing BUXOM formulas in matching shades. At $35, it costs less than the $48 that BUXOM says the two items would cost bought one by one.

Products and Shades

The kit contains two products:

  • Full-On Plumping Glossy Lip Oil in Dolly. BUXOM's Instagram announcement calls this the "Powerful Plumping Lip Oil." The brand's product page uses the name Full-On Plumping Glossy Lip Oil.
  • Power Line Plumping Lip Liner in Dangerous Dolly. BUXOM calls this liner one of its best-sellers.

What the Brand Says

Lip oil: According to BUXOM, the formula uses a Unique Peptide Complex to help lips look plumper. The brand describes the oil as lightweight and non-sticky, with an oversized, plush doe-foot applicator. BUXOM says the oil makes lips feel softer and smoother and that it is dermatologist tested.

BUXOM also cites a US clinical study of 32 people. The brand reports that the study found:

  • instant plumping and all-day hydration
  • 25% fuller-looking lips after one week
  • a 71% reduction in the look of fine lines and wrinkles on the lips in one week

Lip liner: BUXOM describes the Power Line liner this way:

  • highly pigmented, with a creamy feel
  • won't feather or bleed
  • an always-sharp chiseled tip and a built-in blending brush
  • waterproof, with 8-hour wear

How to Wear the Duo

  1. Outline the lips with the Dangerous Dolly liner, using the chiseled tip for a sharp edge.
  2. Use the built-in blending brush to soften the line inward, so there is no harsh border.
  3. Apply the Dolly lip oil over the top with the doe-foot applicator for a glossy finish.

For a softer daytime look, fill in the whole lip with the liner before adding the oil. This also gives the colour a longer-lasting base.

Where to Buy

The set is a limited edition, so stock may not last through the season.
