Conclusions: The data suggest niacinamide is an effective skin lightening compound that works by inhibiting melanosome transfer from melanocytes to keratinocytes.
It can also block the specific enzyme responsible for skin discoloration, including dark spots, hyperpigmentation, and even freckles. This way, niacinamide can help even out an uneven complexion, reduce the appearance of dark spots caused by sun damage, skin conditions, acne, or dryness.

Does Hyperpigmentation Get Darker Before It Fades? Yes, sometimes, the body speeds up pigment production before the cells break down and fade. But sometimes, the dark spots can also fade without getting darker first.
Niacinamide: Many times, trendy ingredients suddenly stop working or showing any improvement. This could be because of two reasons that the product is piling up on the skin and is not getting absorbed properly, or the ingredient is not suiting the skin leading to itching, redness, or rash.
