This night treatment uses enzymes and AHAs to gently resurface the skin, while also supercharging skin hydration and barrier repair. Midnight Melt is a night treatment that acts as both a serum and a mask. This pillow-proof formula exfoliates and resurfaces the skin, using enzymes to literally melt away debris from the skin. Skin free from debris can then better absorb the hydrating and barrier repair actives within this serum. Midnight Melt also has a refillable bottle - so when you're finished, keep the outer bottle and pump, and replace your product with one of our refill cartridges.
