Background/Purpose: The sunless tanning agent dihydroxyacetone (DHA) is known to protect against longwave ultraviolet radiation (UVA) and visible light. Recently, our laboratory has shown that DHA in addition offers a modest sun protection factor (SPF) in humans. We conducted this study in order to investigate the durability of the SPF provided by DHA. 
An Analysis of the Toxicity of Dihydroxyacetone in Spray Tanners when Exposed to Ultraviolet Radiation
Dihydroxyacetone, recognized as DHA, is a common additive used in spray tans responsible for providing pigmentation to the skin similar to a UV tan via the set of mechanisms known as the MaillardExpand
Improving Photoprotection and Implications for 25(OH)D Formation
TLDR
The best method of photoprotection by sunscreen is two consecutive applications before sun exposure, ensuring the use of sufficient amounts of sunscreen and minimizing the unprotected skin areas. Expand

The modern formulation of dihydroxyacetone (DHA), the only sunless tanning solution approved by the Food and Drug Administration (FDA), is combined with bronzers and moisturizers to deliver aExpand
Effect of Simultaneous Administration of Dihydroxyacetone on the Diffusion of Lawsone Through Various In Vitro Skin Models
TLDR
This study confirmed that combined DHA and lawsone provided effective blocking of ultraviolet light through products bound in keratinized tissue and suggested further in vitro and in vivo study is required to determine the safety of this system. Expand
Study of sunless tanning formulas using molted snake skin as an alternative membrane model
TLDR
The DHA concentration was found to influence the initiation of the pigmentation in both sunless tanning systems (emulsion and gel) as well as the time required to increases by a given amount on the tanning index. Expand
The benefits and risks of ultraviolet tanning and its alternatives: the role of prudent sun exposure.
TLDR
This article discusses pertinent issues surrounding indoor tanning, the role of sunless tanning products, and prudent sun exposure and analyzes several health benefits of UV exposure, including vitamin D production and improved mood. Expand
Advances in Photoprotection
TLDR
The three pillars of photoprotection are modifying behaviour leading to excess UVR exposure, wearing protective clothing and eyewear and using adequate amounts of sunscreen as an adjunct to these protective strategies. Expand
Photoprotection from Sunless Tanning Products and Colored Cosmetics
Photoprotection is traditionally associated with the use of sunscreens and physical objects, such as clothing, sunglasses, hats, umbrellas, scarves, etc., together with behavioral modification byExpand
Comparative in vivo study of the efficacy and tolerance of exfoliating agents using reflectance spectrophotometric methods.
TLDR
Evidence showed that the mandelic acid and grape juice acid mixtures were able to induce a slower and safer peeling action in comparison with glycolic acid, which suggests that the methodologies and protocols used in this study may help in choosing the most appropriate topical agents for skin exfoliating treatments.

The Vital Consequences of Choosing the Right UV-filter for the Prevention of Free Radical Boosting in UV-irradiated Skin after the Application of Self Tanning Creams: Part 2
It is generally known that the Maillard reaction which is responsible for the sunless tanning is correlated with the generation of free radicals in the skin. The number of free radicals isExpand

Dihydroxyacetone naphthoquinone protection against photosensitivity.
TLDR
30 patients with multiple types of sunlight sensitivity were treated successfully with DHA/lawsone sunscreen, and about 80% of the patients experienced sufficient protection during the summer months to lead a virtually normal life-style while participating in all kinds of outdoor activities. Expand
Photoprotection of patients sensitive to short and-or long ultraviolet light with dihydroxyacetone-naphthoquinone.
TLDR
The topical sunscreen, dihydroxyacetone/ lawsone (DHA/lawsone), was tested on 18 patients with photosensitivity disorders and increased sunlight tolerance in these patients twelvefold, thus providing four times greater protection against sunlight than did the previous technique employing mixtures of the components. Expand
Protection against long ultraviolet and/or visible light with topical dihydroxyacetone. Implications for the mechanism of action of the sunscreen combination, dihydroxyacetone/naphthoquinone.
TLDR
DHA treatment of skin was considered to provide no protection against UV, but the combination of DHA and lawsone (2-hydroxy-1,4-naphthoquinone) is preferred to DHA alone, because it provides rapid, positive protection over a range extending from short UV into the visible region of sunlight. Expand
Sunless skin tanning with dihydroxyacetone delays broad-spectrum ultraviolet photocarcinogenesis in hairless mice.
TLDR
This is the first study to show that the superficial skin coloring generated by frequent topical application of DHA in high concentrations may delay skin cancer development in hairless mice irradiated with moderate UV doses. Expand
A Sunscreen–Tanning Compromise: 3D Visualization of the Actions of Titanium Dioxide Particles and Dihydroxyacetone on Human Epiderm
TLDR
The tanning effect is enhanced by UV irradiation and appears localized in the near-stratum corneum layer as revealed by depth analysis of the time signal. Expand
Dihydroxyacetone. Recent clinical investigative studies.
TLDR
Investigation of the mechanism of the reaction, some physical characteristics of the color complex, some toxicologic studies, and experiences with the topical use of DHA in clinical dermatology suggest that DHA may become an interesting experimental tool. Expand
Staining of Skin with Dihydroxyacetone
The reaction of skin with dihydroxyacetone to produce a brown "artificial tan" appears to proceed through combination with free amino groups in skin proteins, and particularly by combination ofExpand
The physical aspects with respect to water and non-enzymatic browning.
TLDR
Kinetic studies at normal storage conditions show browning to occur by a zero order reaction although the sugar and amine initial reaction occurs by first order, and the zero order kinetics can be used to predict shelf life under a variable time-temperature-humidity condition. Expand
The validity and practicality of sun-reactive skin types I through VI.
TLDR
It was decided that a brief personal interview regarding the history of the person's unburn and suntan experience was one approach to estirnate the skin tolerance to uitraviolet radiation (UVR) exposure. Expand
Threshold level for measurement of UV sensitivity: reproducibility of phototest
TLDR
Phototesting is based on subjective assessment of erythema and is not as precise and reproducible as expected, so it is recommended that the barely perceptible eryththema reaction should be used for measurement of the minimal ery thema dose. Expand
