Vaseline is one of those products that almost everyone has at home – somewhere between Band-Aids, hand cream and that mascara that you should have thrown away before the Olympics. At first glance, it’s nothing special: a transparent, thick, greasy texture, no glamorous packaging and no promises of a “revolutionary formula from the Swiss glaciers”. Yet it has survived decades in the world of skincare and still holds its position as one of the most useful products for dry skin, chapped lips, rough heels and that radiant “dewy” look that is sold as a luxury these days – but in fact, you can create it with a little Vaseline.
