What is an effective liver spot laser treatment?

Solta Lasers has a great option for safely treating
brown spots on the face, neck and decollate.  The Clear and Brilliant has its
newest technology called Permea  which utilizes a non-invasive laser
for collagen rejuvenation and clearing pigmentation.  It safely treats melasma and ethnic skin types without risk of hyperpigmentation#ClearandBrillliant    #Permealasertreatments    #liverspottreatments

Perméa is the latest technology utilizing a
low-power1927nm non-invasive fractional laser for rejuvenation and
pigmentation. The Clear + Brilliant Perméa is designed to address early signs
of aging and help to prevent them.The results of the treatment are both
immediate and progressive. A few days after the treatment, your skin will start
to feel softer, look brighter and show more even tone and reduction of brown
spots#ClearandBrilliant  #Permeatreatspigmentation   #Permealasertreatments

The best laser to remove dark skin patches assuming they are senile lentigines (aging sunspots) is the 1064nm laser because it can be done with little or no damage to the skin surface cells. It is the same one that is used for tattoo removal. It can be Nd:Yag or Alexandrite.
More than one treatment may be required. If your mother is a darker skinned asian the skin should be cooled at the same time as the laser application so that the surface cells are not damaged.
It is imperative that you have the correct diagnosis before undergoing this treatment. Other types of skin disorders may not be affected by this laser and some such as melasma can be made worse.
The aging sunspots are caused by the gathering of skin pigment cells into clumps rather than the usual wide spread of the cells over the skin surface. This gathering is a natural part of the aging process. If there is a large number of these sunspots on the face most doctors would recommend an ablative laser treatment instead of the 1064nm laser to try and even out the skin color.

A Q-switched Nd:YAG laser, using a wavelength of 532 nm, is a very effective laser. The Alexandrite laser (wavelength 755 nm) can also an effective option, and if both lasers are available test areas can be treated to investigate which is optimal to use for the specific skin type. For darker Asian skin, it is important to avoid sun exposure and a tan, and use effective sun protection before as well as after the laser treatment. A prescription lightening cream will be needed after the treatment to treat "rebound" darkening which is common in darker skin types. Select a board-certified cosmetic dermatologist who has experience with laser treatments for darker skin. 

The newest laser from Fraxel, the Dual, has 2 wavelengths - 1550 and 1927. The 1927 is a brand new wavelength, with no other laser company at this time having it. It has no downtime and can resolve most pigmentary issues with 1-3 treatments.

There is some bronzing of the skin of the face for a few days and then that peels off with the pigmentation. Particularly with Asian skin, I find that IPL is hard to get rid of spots because you have to turn the settings lower (because the regular skin will compete for the IPL heat). I would consider hydroquinone if you do the 1927 after the treatment.

Ordinarily, the best laser for removing sun / age / liver spots is not strictly a laser but IPL. It emits light energy which is selectively absorbed by the darker pigment of the lesion destroying it without heating the adjacent normal skin. However - this will be problematic in your case because:- it cannot be used in darker (Asian or Black) skin where other pigment attracts the energy as well- the size of the lesion and its proximity to the lower lid needs to be closely evaluated. Any removal of lesions here MAY pull the lower lid down if the lid is loose causing SCLERAL (white) Show or an ECTROPION (picture Google these terms to see what I mean).
There is no simple pat answer to your question. A photograph and an examination of the lid tone are needed to select the best removal modality.

I treat alot of Asian patients with this common problem. If your mum has v v pale Asian skin than a 532 Q switch laser followed by bleaching creams can be helpful. Post laser skin darkening is common if she has darker skin types. Sunprotection before and after any laser is critical. My next choice (if they are raised) is an erbium laser (fully ablative)Other techniques I use include BBL or IPL, 520 filter, followed by 1927 Fraxel. May require 3 treatments for optimal outcomes. Dr Davin LimAesthetic and Laser DermatologistBrisbane and Gold CoastAustralia
