Summary
Tinted sunscreens offer protection from visible light, but shade diversity is lacking. Most products have one shade, leading to tone incompatibility issues, especially for darker skin tones.
Area of Science:
- Dermatology
- Cosmetic Science
- Photoprotection
Background:
- Visible light (VL) can affect skin pigmentation and cause erythema.
- Tinted sunscreens (TSs) with iron oxides (IOs) and pigmentary titanium dioxide (PTD) offer protection against UV and VL.
- Consumer preference for TSs is influenced by skin tone compatibility.
Purpose of the Study:
- To investigate factors influencing consumer preference for over-the-counter tinted sunscreens based on skin tone.
- To identify areas for improvement in tinted sunscreen formulations regarding shade diversity.
Main Methods:
- Analysis of descriptive data and customer reviews from an online supplier for over-the-counter tinted sunscreens.
- Qualitative coding of the top 10 most helpful reviews using a consensus scheme.
- Categorization of positive and negative descriptors related to product performance and shade matching.
Main Results:
- Most tinted sunscreens offer limited color shades, often only one.
- Tone incompatibility was the most frequent negative feedback, particularly from consumers with darker skin tones.
- Products with more shade options were more frequently recommended.
Conclusions:
- There is a significant need for increased shade diversity in tinted sunscreen products.
- Addressing the lack of shade options is crucial for improving consumer satisfaction, especially for individuals with darker skin tones.
- Tinted sunscreens can provide cosmetic and photoprotective benefits, but formulation inclusivity is key.

01:19Pigmentation
2.8K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

01:14Changes in Skin Color: Clinical Perspectives
2.3K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:23Role of Skin in Vitamin D Synthesis
5.8K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

4.6K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

6.5K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...
