First of all, I hope you are gaining self-confidence as your complexion improves. I recommend a good moisturizer with an added sun protection before applying a mineral base make up. Also, if there is any pustules, try to avoid contaminating the area with your application of the makeup. At night, please remember to gently cleanse the area and apply a pH balance moisturizer that contain very long chain fatty acids and cholesterol esters. Niacinamides will also decrease erythema or the look of redness. Good luck, take care.

I agree with Dr. Pozner, a 1064nm works best with skin type III and higher. It is also important not to be in the sun for two weeks prior to your treatment.

The dose of Isotretinoin is a cumulative medication. While on this specific medication your face will become drier. Using products meant to dry the sebaceous glands will only make your "worsening phase" more irritated. I recommend a very mild face wash accompanied by a moisturizer which is non-comedogenic. Look for a moisturizer that balances your own pH, has very long chain fatty acids, and contains 18-B glycyrrhetinic acid. Good luck, take care

Melasma is hyperpigmentation. Triggers can range between hormone, sunlight (UV radiation), and heat (stove, fire or sauna); anything that stimulates the melanocytes (pigment cells). Darker complexions may be more prone to the hyperpigmentation. Hydroquinone has been used to treat melasma. I usually recommend a retinoid to help exfoliate if the skin can tolerate. Balance all of the irritants with True Lipids - to hydrate, correct & perfect.

Thank you for your question.  You did not mention your age, but you appear young.  Laser treatments are targeting red pigment.  The results of cosmetic laser treatments may be temporary. 
Your face/cheeks may be a condition called Keratosis Pilaris.  Sometimes evidence of this condition is seen on shoulders, upper arms, and thighs.  Look for hydrating moisturizers that contain long-chain fatty acids and 18-B Glycyrrhetinic Acid to restore the balance in the skin and decrease inflammation. 
Good luck, take care.
