Pairs well with: Hydrating and soothing products — toners, essences, and lightweight creams focused on humectants, panthenol, centella, or beta-glucan help maintain comfort during active use; barrier-support products — simple, well-hydrating moisturisers help offset dryness from azelaic and kojic acid
Avoid using: Strong exfoliating acids (AHA, BHA, PHA) in the same routine, as this formula already delivers exfoliating and pigment-targeting activity; retinoids in the same routine — better alternated to reduce irritation and over-stimulation; very dry or compromised skin without adequate moisturising support
Layering tip: Use this as the primary treatment serum and keep the rest of the routine calming and well-hydrated; if dryness or sensitivity appears, reduce frequency rather than layering more actives
Pro Tip: This is best treated as a targeted treatment, not an everyday default for everyone; those with sensitive or dry skin should patch test first, start with limited use, and ensure the skin is well moisturised to maintain comfort
