“I have really sensitive skin that tends to be on the more dry side," Bieber has previously admitted, so it makes sense that she's a fan of Cicalfate which is specifically formulated with dry and fragile skin in mind. The cult formula contains the brands signature eau thermale water alongside a restorative post-biotic that was developed to create a bandage-effect over skin and it's gentle and effective enough to work across perioral irritations (around the mouth), babies' nappy areas, general dry patches, or for post-shaving or waxing. It even provides sun burn relief and can reduce the appearance of scars, so it's a pretty nifty do-it-all balm. In a previous video shared with her followers, Bieber revealed the following about her skincare regime:< “At night time, I typically go with a more intense moisturiser – something thicker, just to kind of soak into my skin overnight.” This tells us that Hailey is, indeed, a fan of 'slugging' – the skincare trend that sees people coating their face with an occlusive moisturiser, most often a petrolatum-based product, such as Vaseline. This, it is claimed, will help prevent trans-epidermal water loss – meaning less water will get out of your skin – and will help repair your skin's barrier – to even further prevent water loss and more dryness.
