How to remove dark spots on the face from pimples

Inflammation from a pimple can stimulate extra pigment as the skin heals. Picking, squeezing, scrubbing, or repeatedly irritating the area can deepen or prolong the mark. Flat brown or grey areas are commonly described as post-inflammatory hyperpigmentation; they are different from an active pimple and from a depressed acne scar. Other causes of facial pigmentation include Melasma, Sun Spots, or a broader pattern of Dark Patches On Skin.

Use a mild cleanser, moisturiser, and broad-spectrum sunscreen each day; exposed facial skin can darken when sunlight reaches healing marks. Avoid lemon juice, harsh scrubs, and unlabelled bleaching products. Do not pick new pimples, and use acne treatment suited to your skin so new inflammation is less likely to create further marks. A clinician may discuss Skin Brightening Treatment, a Chemical Peel, or Picosecond Laser Treatment after examining the pigment and your skin tone. Introduce one product at a time and stop if burning, swelling, or a rash develops.

Arrange a dermatology assessment if the colour is changing quickly, the area is raised, bleeding, painful, persistently itchy, or unlike your other marks. Seek care sooner if redness, warmth, pus, or increasing tenderness suggests an infection. An assessment can distinguish post-inflammatory pigment from another condition and prevent an irritating treatment from making the colour more noticeable.

Could this be post-inflammatory hyperpigmentation or another cause? Which ingredients suit my skin? How should I protect the area from sunlight? Would a peel or laser be appropriate, and what irritation should prompt me to stop?
