To safely address uneven skin tone or dark spots, look for dermatological products containing gentle active ingredients like Vitamin C, Niacinamide, Kojic acid, Azelaic acid, or Alpha arbutin. These ingredients help brighten the skin by regulating melanin production. Daily application of a broad-spectrum sunscreen (SPF 30 or higher) is essential, as sun exposure triggers pigmentation. Please avoid unregulated products containing mercury or strong steroids, which can cause skin damage. For the safest and most effective results tailored to your specific skin type, I highly recommend consulting a dermatologist before starting any new treatment.

The serum may appear colourless or slightly yellow to light brown over time due to oxidation of vitamin C, which can occur with exposure to air or light. A mild colour change does not always mean the product is unsafe, but a very dark brown colour may indicate reduced effectiveness. As you have sensitive skin, it is best to buy from the official Apollo Pharmacy website or authorised sellers and perform a patch test before regular use. If you notice irritation, redness, or burning, stop using the product and consult a dermatologist.
