If you're looking to treat acne scars, uneven skin tone, sun spots, redness, and other skin discolouration or hyperpigmentation issues, opt for products formulated with actives like vitamin C, alpha arbutin, or azelaic acid, or gentler non-active skin brightening ingredients like niacinamide, rice, and fruit enzymes. Always pair with sunscreen at the end of your morning routine for better results.
