Brief Answer:
Sunscreen+skin lightening creams for regular use
Detailed Answer:
Hi. Thanks for posting your concern at HCM
Your concern is genuine. Freckles are genetically determined. They can reappear if you come off skin lightening creams and sun protection(sunscreen). Therefore you need to use a skin lightening cream regularly as well as a broad spectrum sunscreen throughout the day.
Apart from your concern regarding reappearance of freckles on stopping Melanorm-MS cream there is one more issue which i want to highlight. Melanorm-MS cream that you have been using, though is a gold standard for hyperpigmentary conditions, but it should never be used for a longer duration(say may be more than a month or two). It is used only for the initial 1-2 months of therapy and then switched over to other products which are safer and thus can be used over longer run. The reason I say this is that it is a combination of a potent steroid, Mometasone+Hydroquinone+
tretinoin. Mometasone is a potent steroid which if use for long term can cause side effects like Bleaching of Skin, Acne,
Photosensitivity, Skin thinning/telangiactasia and Facial hair growth (specially worrisome in females).
You could have used a cream containing just plain hydroquinone(2% or 5%) as suggested by Dr. XXXXXXX XXXXXXX
If i was you treating doctor I would have asked you to use a cream containing one or more of the skin lightening ingredients like
Glycolic acid, Hydroquinone,
Kojic acid, Arbutin,
Magnesium ascorbyl phosphate etc either alone or in combination. These products are safe to use even if used over long term because they are steroid free.
Therefore I would advice you to stop Melanorm cream and switch over to the safer options which i have mentioned above. These creams are easily available on prescription of a
dermatologist. They should be used under the supervision of a dermatologist.
You can also avail Glycolic peel sessions (6-8) from a dermatologist. It would be effective for both
acne scars as well as freckles
You should also use a broad spectrum sunscreen, which offers both UVA and UVB protection throughout the day.
Hope this answers your query
take care
