What it does: A real wonder ingredient, niacinamide works by improving the skin’s natural protective barrier. It locks in moisture, blocks harmful pollutants and stimulates the production of collagen. It can also reduce redness and pigmentation marks by evening skin tone.
Best for: Suits all skin types although rosacea or acne-prone, oily and sun-damaged skin will particularly benefit. It can be used morning and evening and is a great ingredient when used in suncare.
Research also suggests that niacinamide can help improve your skin’s tolerance to retinol due to its barrier-strenghtening properties, so if you have experienced irritation when using vitamin A-based products it may be worth trying this first.

It can also help treat skin disorders such as acne and psoriasis, while reducing pigmentation marks and smoothing the complexion. It has the power to stimulate cellular repair at the deepest level, boosting the circulation so skin looks healthier and younger.
Best for: Rejuvenating and reversing signs of ageing. It is also excellent for oily and acne-prone skin as it reduces oil production.
Retinoids are available on prescription only but retinols (a gentler version of retinoid) can be found in many over-the-counter creams.
Retinol, which should be applied in the evening, can irritate the skin so if you experience redness or flaking try using it every second or third night until your skin becomes used to it. When using a retinol-based cream it is essential to wear sunscreen during the day.
