“A lot of brands charge against the odds for retinoid products, which makes this one, merely £7, so desirable. Recommended to me by a top London dermatologist, the milky, fast-absorbing formula doesn’t cause irritation in the form of redness and flaking. Instead, it works to smooth skin texture and tone. I use it at night after cleansing and credit it for keeping my PCOS-related breakouts under control among other helpful acne ingredients, such as salicylic acid.”
