If your skin is hyper sensitive or has reacted to a lot of products, I generally recommend visiting a beauty salon or department store where you can patch test the products before buying, rather than buying online.
Discolouration – If your discolouration is symmetrical, for example on the cheek bones on each side or on your forehead, nose/top lip/chin this usually indicates melasma. Unfortunately topical products won’t help with melasma which would require professional treatment such as laser. Most skin clinics will offer a free consultation and can advise on the best treatment.
