I suggest a broad spectrum sunscreen along with pigment reducing agents
Hello. Thank you for writing to us
I have taken note of your query and I have understood it.
Tanning is your main concern.
I want to stress on the use of a broad spectrum sunscreen and effective use of it.
An ideal sunscreen should be broad spectrum i.e it should have both UV A as well as UV B coverage.
A sunscreen that I would suggest for you should have an spf of 50 or more.
It should be reapplied every 2-3 hours specially if outdoors and in desired quantity to be effective i.e 3 ml for face and neck, 3 ml for both arms.
Having said that.. A sunscreen would not remove already existing XXXXXXX It would only prevent further tanning Or re-tanning.
Regarding already existing XXXXXXX you may use a cream containing one or more of the pigment reducing agents like Glycolic acid/ Alpha Hydroxy acids; kojic acid; arbutin; hydroquinone etc.
Systemic skin lightening agents like tranexamic acid, glutathione, L-cysteine peptide etc have become popular in recent years and are claimed to lighten the skin.
However, none have been adequately tested and there is no strong scientific evidence of efficacy.
They are available in tablet or capsule form and can be purchased online.
One of my main concerns are the areas not exposed to the sun such as my gluteus and stomach which rarely get any sort of sun exposure. Those areas have also darkened, could this be due to some sort of hormonal change?
Regarding existing areas of darkness..
- if left for a long enough period will the darkening eventually fade by itself or will it remain its current colour
- are there any products you would recommend I could use
Upload Images; can try topical Hydroquinone + sunprotection
I would like to keep 2 more possibilities i.e Ashy dermatosis and Lichen planus pigmentosus, considering that skin darkening is also affecting sites that are normally covered.
I would request you to upload a few Images of the affected areas preferably before and after photographs for comparison.
You may upload images either at "Reports Section"
You may also mail me the image at YYYY@YYYY
Kindly mention the subject of this mail as Attention Dr.kakkar.
Skin color is a combination of constitutive pigmentation and facultative pigmentation.
Constitutive skin color is the natural, genetically determined color of the epidermis e.g the color of skin that is normally protected from sun i.e underside of upper arm.
Facultative skin color results from exposure to UV light and other environmental factors.
Skin lightening agents may progressively revert back the facultative color to the constitutive level and normally this color change will not go beyond the constitutive level.
You may try and use a hydroquinone based cream/ lotion once daily at night for a few weeks along with sun protection and regular use of a sunscreen, throughout the day.
I have uploaded some pictures up on my reports. The image of the difference in skin tone between my arms is the same sort of difference my neck has with my face. My face was originally the same tone as my feet. Over the last couple of years i have not had much sun exposure and stay out of the sun as well as broad spectrum sunscreen. thank you
I suggest testing for serum Vitamin B 12 levels
I have reviewed the Images.
The most contrasting darkening is at elbows, dorsal hands/ feet with periungual accentuation and lips.
This type of pigmentation pattern distribution is suggestive of Addisonian hyperpigmentation and Vitamin B 12 deficiency (methylcobalamin deficiency) is a common cause.
This is in addition to the general tanning
I suggest you to get tested for serum vitamin B 12 levels. If levels are found deficient an Oral vitamin B 12 supplement can also be added
Is your oral mucosa i.e buccal mucosa and tongue also involved with pigmentation?
At glimpse within my mouth i can't really see any pigmentation. I already take oral multiple vitamin tables containing 1.0µg of vit b12 and eat a lot of chicken and milk.
My father shows similar sort of symptoms as i do in relation to the differences in skin contrast however within his mouth there is a lot of pigmentation. I don't know if this could be of any help. Thank you
In January I went to the GP for feelings of fatigue, penile dysfunction, transient shortness of breath and need to urinate frequently. I had a blood test for levels of Vitamin D, B12, and thyroxine hormone. My results where first discussed with a nurse who said my levels of vitamin B12 where low and that I showed signs of anaemia. However when discussing the results with my doctor he said everything was fine.
I want you to be sure about the Vit B 12 deficiency
Since there were different views about Vit B 12 Levels previously therefore I want you to be more sure about that.
The dose of Vitamin B 12 that is normally prescribed for Vitamin B 12 deficiency and addisonian hyperpigmentation is much more that what you are taking at present i.e 1 mcg.
The therapeutic dose of Vitamin b 12 is approximately 1000 fold of the dose that you are currently taking (varies from 750 mcg - 1500 mcg per day)
The skin, may be the site of the first manifestations of Vit B 12 deficiency, highlighting the importance of vitamin B12 testing in the early diagnosis of this condition.
Kindly go through the link as well..
You are welcome
Yes. Do keep me updated.
Tone and pigmentation should improve
Yes, Tone and pigmentation should improve on Vitamin B 12 supplementation, if it is actually due to its deficiency.
Any more clarifications are most welcome.
I mentioned our discussion. I had my GP visit today. No blood work was done but he looked at the previous blood test results I mentioned from above. All my blood readings where normal with slightly low levels of Vitamin D. He prescribed me with a vitamin D3 supplement of 500mcg, 2 tablets to be taken everyday for 10 days followed by once every month thereon after.
Regarding the darkening -
He didn't check to look at the difference in contrast after I mentioned it. I made him look at the pigmentation on my elbow. He said that there is nothing he can do and that the differences in contrast i mentioned are normal within the XXXXXXX ethnic group.
It is his individual discretion
I don't think the pigmentation on your lips, elbows, dorsum of toes and periungual areas is simply ethnic in origin.
There was no harm in supplementing with high dose Vitamin B 12 for a month despite no detectable deficiency.
It was worth a trial because the pattern was so distinctive of addisonian hyperpigmentation
I have no answer for his decisions. You can continue as per his advice and follow up after sometime.
I was not satisfied by the outcome of my visit. I am going in to revisit the GP again in 2 weeks. However within the next 2 weeks I'm going to get seen privately by a dermatologist as a second opinion. Is there any specific points you could possibly advise I mention during my consult?
Keep me updated.
You can specifically ask your dermatologist to check for any Oral pigmentation?
Don't mention my diagnosis beforehand and let him/her examine and keep there own diagnosis/ possibility. What do he/she thinks this is due to?
Later you may mention my discussion with you and his/her opinion on that and the likelihood that this pigmentation would improve with Vitamin B 12 supplementation.
Keep me updated.
Thank you I will do. What are you thoughts of attempting to take over the counter Vit b12 (cobalamin) supplements of 1500mcg myself and checking for changes over time.
