Bubble Water Slide Hydration Boosting Serum This new serum from the current 'Sephora Kid' generation favourite, packs a real punch in delivering hydration to the skin. The packaging may look fun but Bubble Water Slide Hydration Boosting Serum (£18) is serious when it comes to adding moisture. I was very impressed with how smoothly it absorbed into skin to leave a hydrated glow. Image Source: Getty Bubble Water Slide Hydration Boosting Serum £18 from beautybay.com Buy Now
