Pigmentation Pigmentation can be one of the most difficult skin concerns to improve as it takes time and perseverance. Glycolic acid can help immensely with gently exfoliating the skin and brightening overall skin tone. Again, don't forget to use a moisturiser, such as Natural Moisturising Factors or Squalane, to maintain moisture whilst treating the hyperpigmentation. What to use in the morning: Alpha Arbutin 2% + HA (£7), has a high 2% concentration rather than the standard 1%, which reduces the appearance of spots and hyperpigmentation. Niacinamide 10% + Zinc 1% (£5), Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F (£15) is one of the most stable derivatives and provides overall skin brightening. What to use in the evening: Glycolic Acid 7% Toning Solution (£7), Alpha Arbutin 2% + HA (£7), Azelaic Acid Suspension 10% (£6), or Advanced Retinoid 2% (£8). Once a week: AHA 30% + BHA 2% Peeling Solution (£6).
