Managing common vulvar skin conditionsHarvard Health

Aug 31 2020 · A mouth condition called lichen planus is another cause of vulvovaginal problems. (The term "lichen " as applied to skin disorders refers fancifully to skin lesions that resemble lichen on rocks.) Long-term treatment with oral steroids immune suppressants or antibiotics can affect vulvar skin and raise the risk infection. The major challenge for in situ spinel forming LCCs is crack formation due to volumetric expansion. The expansive behavior is commonly caused by (i) MgO hydration during curing and dry-out stage and (ii) in situ spinel formation and formation of calcium hex-aluminate (CA 6) at high temperatures.To overcome these problems small amounts of microsilica are often added e.g. 0.5–1.0 .
