Common questions about face serums for normal skin and uneven tone
With consistent use and proper sun protection, many people start to notice a general improvement in brightness and texture after about six to eight weeks. Individual dark spots and tanning patches can take longer, often several months, because the pigment has to gradually move up and out as your skin renews itself. It is also common for marks from deeper pimples or long-standing sun exposure to fade very slowly. If you have used a well-formulated brightening serum correctly, along with daily sunscreen, for around three months and you see almost no change, it may be time to reassess. That could mean adjusting your routine, choosing a different active with guidance, or consulting a dermatologist to check for conditions like melasma that are harder to treat at home.
