I don't often use a gel cleanser (I'm more of a cream cleanser kind-a-girl), but when I do (after the gym, when I've worn a lot of makeup), it's usually the Honest Beauty Gentle Gel Cleanser (£16). The gentle gel doesn't strip the skin, in part thanks to the fact there's glycerin in the formula, and it's incredibly soothing, due to the addition of calendula and chamomile extracts.
