Abstract
Full term newborns have a skin that rapidly develops towards adult skin. From the anatomical point of view, the differences are limited, but some changes at birth are responsible for the physiological differences between the skin of infants and adults. Newborns skin exhibits the same barrier function and absorption properties as adults, but external conditions for newborns may be different from those for adults, and these differences may lead to different skin absorption profiles between these two groups. Also, a baby's temperature regulation (transepidermal water loss (TEWL) and sweating) is not completely developed and the skin becomes easily infected, which is mainly due to changes in pH and immaturity of the skins defense system. This implies why only cosmetics with safe ingredients should be used for newborns. The initial aim is to formulate a simple, pure, gentle and pathogen-free product. Systemic side effects are not expected with washable products but should be taken into account for leave-on products. Great attention should be given to cosmetic products used in the napkin area, especially where there is a possibility of rash. If necessary, more safety precautions should be taken for these products.

Abstract
Cosmeceuticals are the fastest growing segment of the personal care industry, and a number of topical cosmeceutical treatments for conditions such as photoaging, hyperpigmentation, wrinkles, and hair damage have come into widespread use. In the cosmeceutical arena nanotechnology has played an important role. Using new techniques to manipulate matter at an atomic or molecular level, opening up new perspectives for the future of cosmeceutical industry. Nanotechnology-based cosmeceuticals offer the advantage of diversity in products, and increased bioavailability of active ingredients and increase the aesthetic appeal of cosmeceutical products with prolonged effects. However increased use of nanotechnology in cosmeceuticals has raised concern about the possible penetration of nanoparticles through the skin and potential hazards to the human health. This review outlines the different nanoparticles used in various classes of cosmeceuticals, and the potential risk caused by nanoparticles on exposure.

Abstract
Background and Aim: One of the most important pathologies of tattooing is granulomatous reaction to the tattoo which is usually represented by symptoms like pain, inflation, redness and tenderness at the tattoo area. Granulomatous reaction to tattoo occurs at all ages and has been seen among both male and female. Due to the new rise in popularity of cosmetic tattoos and its pathologies, we intend to explore a descriptive study of the demographic and histopathologic characteristics of the granulomatous reactions due to cosmetic tattoos.
Methods: Razi hospital patients with proven tattoo granuloma pathology in a 3-year period were identified and studied and their demographic-histological characteristics were recorded. The study is of a cross-sectional type. 196 patients were enrolled in the study, a questionnaire was prepared for each patient and information was collected through them.
Results: The mean ± standard deviation age of the patients was 45.46±8.54. The mean ± standard deviation tattoo time was 4.18±4.33. The mean ± standard deviation frequency of tattooing was 1.64±1.8. The most common tattoo area was eyebrow in 88.3% of the patients and least common was upper eyelid in 0.6%. The most common pathology result was tattoo granuloma in 41.7% of the patients and the least common was Lichenoid in 2.8%.
Conclusion: Considering the highest frequency of pathological diagnosis of tattoo-granuloma (Sarcoidal and foreign body) with 41.7% in our study and observing the relationship between tattoo-granuloma and sarcoidosis in previous studies, complete examination of patients, long-term follow-up of patients which will have sarcoidosis in the future and examining the clinical response to treatment seems logical and beneficial. It is also important to consider whether the treatment of current lesions will play a role in preventing sarcoidosis in the future or not.
