When is laser used in the treatment of skin blemishes?

Why shouldn't laser treatment be done immediately if there is a blemish?

One of the main targets of pigment lasers is melanin. However, the issue is not just the amount of melanin, but also why it increases and its epidermal/dermal location. The laser response is not the same for well-circumscribed solar lentigo and chronic and recurrent melasma.

For which types of blemishes might laser treatment be more suitable?

Laser and light-based methods can yield more predictable results, especially in some well-defined epidermal pigment lesions. Solar lentigo is a typical example of this.

Can lasers be used in the treatment of melasma?

It can be used as an adjunct therapy in selected resistant cases; however, photoprotection, appropriate topical treatment, and assessment of triggers remain the fundamental approach in melasma. Laser does not eliminate the tendency for melasma and may increase post-inflammatory hyperpigmentation or recurrence in some patients.

Can lasers be used for brown spots after acne?

Laser treatment is generally not the first choice for post-inflammatory hyperpigmentation. Topical treatments and photoprotection are considered first, especially in darker phototypes; laser may be an adjunct option in selected, resistant cases.

Are red acne scars pigment spots?

No. The red/pink appearance after acne is mostly associated with erythema following inflammation, and targeted vascular interventions may be necessary. First, a distinction must be made between redness, brownness, and true scarring.

Can all brown moles be removed with a laser?

No. If there is asymmetry, irregular borders, multiple colors, rapid growth, bleeding, or other suspicious features, a dermatological evaluation and, if necessary, a dermoscopic evaluation are required before aesthetic laser treatment.

Which skin lesions can be treated with a Q-Switch laser?

Q-Switch lasers can be used for selected solar lentigines, some ephelides, certain dermal pigmentations, and tattoos. However, they are not a treatment for all blemishes.

Is a picosecond laser better?

It may be effective for some pigment problems; however, being a newer technology doesn't mean it's better for every pigment problem.

Can Thulium laser be used?

1927 nm thulium systems can be used to target superficial photodamage, pigment irregularities, and skin quality; in suitable patients with melasma, they can be part of a combined treatment plan.

Why does skin type matter?

Darker phototypes have higher levels of epidermal melanin, which can increase the risk of burns and post-inflammatory hyperpigmentation. Skin type influences the choice of device, energy level, and protocol.

Can laser treatment completely remove blemishes in a single session?

It depends on the type of skin. Some solar lentigines may show a significant response in a few sessions; melasma and widespread PIH may require longer and combined treatment.

The decision to perform laser treatment on a pigmented lesion is made after diagnosis. Melasma, solar lentigo, post-inflammatory hyperpigmentation, and suspected pigmented lesions do not require the same approach; in some patients, not performing laser treatment is the correct clinical decision.
