A 35-year-old woman from Khanh Hoa, My An, asks if her long-standing patchy and deep-seated melasma, which makes her sensitive skin prone to redness after procedures, can be treated with laser without worsening the condition or causing post-treatment hyperpigmentation.

Blue light, hormonal changes, diet, stress, and post-acne inflammation contribute to skin darkening and dullness, in addition to UV radiation.

Trinh, 35, developed melasma during pregnancy, which worsened and spread one year after childbirth, leading her to seek laser treatment.

Improper sun protection, frequent skin whitening, and overlooking internal factors can lead to melasma and freckles becoming darker and more challenging to treat.
