DRSQ’s Advanced Vitamin A serum with 1% retinal (retinaldehyde) is a potent step-up formula for the ones who have previously used starter and medium potency vitamin A serums. 

This is infused with advanced retinal (retinaldehyde), niacinamide, vitamin C, lactic acid and DNA peptides to slow down the ageing process of the skin caused by external factors, such as sun exposure and pollution.
