While we don’t agree on the steep pricing of La Mer The Treatment Lotion Hydrating Masks, we recognize their benefits, including extreme hydration, plumping effect, glow, and generally healthy-looking skin. Some of the key ingredients of this product include the signature Miracle Broth™ of La Mer, Micro-Fiber Technology and Revitalizing Ferment, all working to solve issues of dryness, signs of aging, and dullness. Each pack of mask also contains a lot of treatment, which we found too excessive, but helpful in hydrating other parts of the skin aside from the face. However, another thing that we did not like was that it caused a tingling effect and a bit of redness to our skin, which may be worse for those with very sensitive skin.
