"I have to say that after a 4-week use, the product did not dry my skin out/caused irritation or sensitivity. The squalane and jojoba seed oil mixture really helps with hydration during the night and leaves my skin dewy and hydrated when waking up in the morning." - Andreea on CultBeauty

"This does exactly what it claims. It makes fine lines practically disappear and wrinkles look smoother and softer. The cream is thick and rich without feeling heavy. I wouldn’t use anything else now." - Adele on Ren's website

"I have used this product almost every night for the past two months and have noticed significantly less facial redness and smaller pores in my T-zone. A must have." - Molly on Amazon

A product of Vitamin A, Retinol is used in serums and creams for its anti-ageing properties. It encourages skin-renewal and prevents the appearance of wrinkles and fine lines.

Best used as part of your night-time skincare routine. If you use Vitamin C and Retinol in your routine, use the Vitamin C in the morning and Retinol at night - never together.

As a Retinol newbie, start with the lowest strength you can get your hands on to make sure your skin can tolerate the product before gradually increasing the strength over time. Additionally, once you start using Retinol, you need to include an SPF moisturiser in your daily routine - can't ignore the SPF.
