Lightness: Lightness is a shading term regularly utilized by (advanced/simple) imaging framework. It characterizes run from dim (0%) to completely enlighten (100%). A shading can be helped or obscured by changing its softness esteem.

Fractional 1550-nm ytterbium/erbium fiber laser was used by Rerknimitr et al. in a study that included 30 patients with a total of 120 IGH lesions.29 Patients received four treatments at 4-week intervals. Assessment was performed with colorimetry, digital photography, and digital dermoscopy at weeks 0, 4, 8, 12, and 16.29 According to the authors, 83.34% of the lesions that received treatment exhibited some type of improvement compared to only 18.34% of the control group lesions.29 Adverse events included transient mild erythema and edema.29 No post-inflammatory pigmentation was observed, possibly making this laser a more suitable option for patients with darker skin phototypes. In a more recent study by Chitvanich et al., 30 patients received treatment with fractional 1550-nm ytterbium/erbium fiber laser every 4 weeks combined with twice daily topical application of 0.1% tacrolimus ointment on lesions on one side and placebo on lesions of the other side of their body.30 Photographic evaluations demonstrated that 91.67% of lesions in the treatment group exhibited some improvement compared to 18.34% in the control group.30 Similarly, the relative lightness index of IGH reached statistical significance at week 12, after three sessions of laser treatment (p = 0.026).30 The authors suggest that the use of erbium laser may improve the absorption of tacrolimus in the skin, further potentiating its efficacy.30 Adverse events included transient erythema and edema.30
Introduction to the second edition
Published in Roger Neighbour, The Inner Apprentice, 2018
Ho hum. Where are these reflections leading us, other than to the usual middle-aged conclusion that things are both more complicated and less important than first we thought? I think it is best to treat these apparently weighty concerns with as much lightness as we can manage. If any change in your own teaching and learning should follow your reading of this book, it will happen mainly, as Forster put it, by one subconsciousness calling to another.

Results showed a decrease in lightness values in all study groups after aging. This reduction was greater in Variolink compared to Choice 2 (p < .005) but there was no significant difference between groups 2 and 4 or groups 3 and 5 (p = .33) so covering the cement with ceramic did not make a difference in lightness. Regarding Δa, all samples underwent red discoloration. This discoloration was greater in Variolink compared to Choice 2 (p < .0001). Also the difference between groups 2 and 4 or groups 3 and 5 was significant (p < .03) so the amount of cement redness could decrease throughout the ceramic. Regarding Δb, all samples became more yellowish after aging. This discoloration was greater in Variolink compared to Choice 2(p < .005) and the difference between groups 2 and 4 or groups 3 and 5 was significant in this respect (p < .0001). So the ceramic layer could mask the yellowish discoloration in cement to some extent.

There was a significant day-by-treatment interaction (p < 0.001) for the lightness component (L*). Multiple comparisons of treatments at each day were conducted and showed that RSDL differed from all other treatments at all measurement days for L* (Figure 5). Significant differences among treatment groups (p = 0.0369) and among days (p = 0.0010) were observed for the red/green component (a*). However, no significant pairwise differences were observed between treatments, but significant differences between day 7 and days 14, 21, and 28 were observed (p < 0.05). The blue/yellow (b*) component showed a significant interaction of treatment-by-day (p < 0.001), and multiple comparisons of treatments at each day were conducted. While there were some significant differences at multiple days between Film, Foam, NC, NC_RSDL, and Xeroform, the consistent differences and the majority of significant differences were between RSDL and all other groups at various days ranging from 7 to 56 (p < 0.05). For overall colour (E*ab) a significant interaction of treatment-by-day was observed (p < 0.001), and multiple comparisons of treatments at each day showed that RSDL was significantly different from all other treatment groups at all days (Figure 6). The collective results of the colorimetry data indicate that RSDL altered skin colouration parameters for a portion of the 56-day post-exposure period.
Skin hyperpigmentation treatment using herbs: A review of clinical evidences

High levels of mushroom tyrosinase inhibition (89%) were observed in 1 mg/ml hydroxyphenethyl alcohol, obtained from hot aqueous extraction and solvent partitioning of Hizikia fusiformis plant material. Cellular activities in B16F10 mouse melanoma cells indicated no cytotoxicity over a concentration range of 1–100 μg/ml with suppression of melanin production being similar to arbutin within this concentration range. Thereafter, clinical evaluation was undertaken in male brown guinea pigs whose dorsal skin had been exposed to UVB. Treatment with 2% herbal extract was carried out twice daily for 60 days (with arbutin as comparison), with evaluation using a chromameter (Konica Minolta CR-300)® every 2 weeks. Skin lightness was significantly (p < 0.05) improved after 2 weeks of treatment, with the herbal active being comparable to arbutin. Visible improvement was apparent after 8 weeks (31).
