Hi everybody,
just wanted to share my knowledge of eczema. It's going to be a wall of text, but this for people who have really struggled with chronic eczema like me.
1) Moisturizers - I wouldn't recommend using all those even moderately expensive ones because the costs add up over time. You can save money without skimping on the efficacy of your moisturizer if you know what to look for and where to shop(Chinatown) Here's what to look for:
Vaseline(petroleum jelly) is the most effective. Petroleum jelly is an occlusive which works by acting as a physical barrier between the environment and your damaged skin barrier and hence blocks water loss that causes dry skin. It's also very cheap, please do not buy dubious generic versions of petroleum jelly. However some people may find it too greasy (you have to apply a really thin layer, and after bathing when your skin is wet to trap the water in) or uncomfortable.
If you are one of these people, then try to look for a moisturizer containing
occlusives(lanolin, mineral oil, and silicones such as dimethicone) and
humectants (glycerin, sortbitol, urea, alpha hydroxy acids)
More in depth info can be found from the source here
2) There are 3 things that you should be aware of when using corticosteroids:
- where you apply the cream. Absorption rates are:
Forearm 1%
Armpit 4%
Face 7%
Eyelids and genitals 30%
Palm 0.1%
Sole 0.05%
- potency of the cream.
Group 4: Hydrocortisone (base level of 1)
Group 3: Eumovate (2-25x)
Group 2: Elomet (100-150x)
Group 1: Clobetasol (600x)
The full list of pharmaceutical names under each group can be found here
You can see that the potency of steroids increases exponentially rather than in a linear fashion. If you are using group 1-2 steroids, you should be concerned because the weaker steroids are not working (see my next point)
- steroids have a destructive effect on the skin barrier even while suppressing inflammation. Because atopic eczema is usually caused by a defective skin barrier, this means the corticosteroid therapy may induce further flares by further impairing barrier function.
The paper that reports this is here, a doctor explains the implications of the findings here. I can read the paper in its entirety thanks to my university access, email me if you're interested in its contents.
3) Atopic dermatitis(AD) has a tendency to heal naturally.

4) Topical steroid withdrawal(TSW) - Personally i am going through withdrawal, and i know of several others who have healed completely upon withdrawal. There are many people all over the world going through it, but there are S'poreans too! So if you suspect you are addicted to steroids, you are not alone.
The mechanism of TSW works like such:
- At first, topical steroids are extremely effective, and the side effect of weakening barrier function is not so obvious.
- Over long term use, the degradation of skin barrier progresses gradually, making the skin more sensitive to external stimuli and hence more prone to flareups. But under steroid treatment, inflammation is always under control.
- Should steroid treatment be discontinued, a rebound flare which is more severe than the original eczema may occur, which is distressing for the patient and thus prompting continued usage of steroids. This may serve to suppress the inflammation but at a cost of further destroying the skin barrier.
- When the skin barrier is destroyed completely, the skin cannot prevent inflow of topically applied steroids, causing the blood concentration of steroid to increase and may cause adrenal insufficiency in the patient.
Worldwide support group for TSW is here(ITSAN)
