What customers say: This lip booster makes lips feel incredibly soft, smooth, and cushiony. A few users, however, do not notice a plumping effect.

Softest lips

Abby L. · 2025-09-14 · Verified purchase

This makes my lips feel incredibly soft and hydrated.

★★★★★

Best lip treatment

Leo B. · 2026-05-23 · Verified purchase

This lip booster has become a staple in my routine. My lips always feel dry and chapped, but this makes them feel so much better. The plumping effect is subtle but definitely there, giving my lips a fuller, healthier look. It feels like a buttery treatment and absorbs well without being greasy. This is the best lip treatment I’ve found.

★★★★☆

Good for overnight

Carrie S. · 2026-10-05 · Verified purchase

It's decent as an overnight mask, but it doesn't give a noticeable plumping effect for me.

★☆☆☆☆

No effect at all

Alexis T. · 2025-11-26 · Verified purchase

Sadly, this product did absolutely nothing for my lips; no plumping, no extra smoothness.

★★★★★

Truly cushiony lips

Dylan W. · 2026-02-21 · Verified purchase

This lip booster really lives up to its name. My lips actually feel cushiony and look fuller, which is a nice bonus. It's also completely fragrance-free, which is great for sensitive skin. This is a repeat purchase.
