A large number of different substances comprise the family of retinoids, which are traditionally described as vitamin A derivatives. By exerting their action through nuclear and cytoplasmic receptors they may improve photoaging. Tretinoin is the best studied retinoid in the treatment of photoaging. Others such as isotretinoin, retinaldehyde, and tazarotene, although less well studied, have given promising results. 
Retinoids in cosmeceuticals
TLDR
Retinaldehyde, which is fairly well tolerated, seems to be the most efficient cosmeceutical retinoid; it has significant efficiency toward oxidative stress, cutaneous bacterial flora, epidermis renewing, and photoaging. Expand
Efficacy and safety of retinaldehyde 0.1% and 0.05% creams used to treat photoaged skin: A randomized double‐blind controlled trial
TLDR
Retinaldehyde (RAL) is the natural precursor of retinoic acid and can be used to treat photoaged skin and the safety profile is good. Expand
Topical Retinoids in Skin Ageing: A Focused Update with Reference to Sun-Induced Epidermal Vitamin A Deficiency
TLDR
Topical natural retinoic acid precursors such as retinaldehyde or retinol are less irritant than acidic retinoids and may prevent epidermal vitamin A deficiency due to nutritional deficiency, exposure to sunlight or any condition leading to free radical production. Expand
Biochemical properties of retinoid-converting enzymes and biotechnological production of retinoids
TLDR
The biochemical properties and active sites and reaction mechanisms of retinoid-converting enzymes in animals and bacteria, including retinol dehydrogenase, alcohol dehydrogen enzyme, aldo-keto reductase, and aldehyde dehydrogensase are reviewed. Expand
Investigation on Toxicity and Teratogenicity in Rats of a Retinoid-Polyamine Conjugate with Potent Anti-Inflammatory Properties.
TLDR
RASP, as a promising lead compound for the treatment of several dermatological disorders and certain cancer types, has apparently minimal toxic side-effects as revealed in this two-generation reproduction study in rats. Expand
Treatment modalities for hyperpigmented skin lesions: A brief overview
TLDR
An overview of treatment modalities available for hyperpigmented skin lesions including the importance of photoprotection, various types of brightening creams, suitable types of chemical peels, specific laser therapies targeted for skinhyperpigmentation, and surgery is provided. Expand
Antiageing Mechanisms of a Standardized Supercritical CO2 Preparation of Black Jack (Bidens pilosa L.) in Human Fibroblasts and Skin Fragments
TLDR
The ability to stimulate extracellular matrix elements, increase growth factors, and modulate retinoid and rexinoid receptors provides a basis for the development of preparation containing BPE-CO2A as an antiageing/skin-repair agent. Expand
Tretinoin-loaded liposomal formulations: from lab to comparative clinical study in acne patients
TLDR
The results of the clinical study in acne patients revealed that F13G showed significantly higher efficacy when compared to marketed product, and the addition of cholesterol in the film hydration method significantly decreased the vesicle size, and increased the percentage of incorporation efficiency at (p < 0.05). Expand
In Vitro Evaluations for a New Topical Anti-Aging Formulation
The study aimed to evaluate the in vitro properties of a new gel formulation (P-3086) as anti-aging treatment. Two in vitro methods aimed to assess and compare the efficacy of the gel formulation inExpand
Development of novel silicon-containing inverse agonists of retinoic acid receptor-related orphan receptors.
TLDR
The phenyl amide disila compound 22 showed the most potent ROR-inhibitory activity among the compounds examined, and its activity towards RORα, RORβ and RORγ was increased compared to that of Am580. Expand

Retinoic acid receptors and topical acne therapy: establishing the link between gene expression and drug efficacy.
TLDR
Following the success and widespread application of prescription-based topical retinoids used for acne and other skin disorders and retinol as a component of various cosmetics, little was known about the mechanism of action of these compounds until the last decade. Expand
Photoaging and the skin. The effects of tretinoin.
TLDR
Improvement with tretinoin therapy has been quantified clinically and histologically, and a major degree of improvement occurs in 6 to 12 months, and maintenance treatment one to three times per week may continue this response. Expand
Sustained improvement with prolonged topical tretinoin (retinoic acid) for photoaged skin.
TLDR
During the open-label study, the statistically significant improvement that had occurred in fine and coarse wrinkling and skin texture during the original study was sustained, despite reductions in dose or frequency of application of tretinoin. Expand
Two concentrations of topical tretinoin (retinoic acid) cause similar improvement of photoaging but different degrees of irritation. A double-blind, vehicle-controlled comparison of 0.1% and 0.025% tretinoin creams.
TLDR
The separation between clinical improvement and irritation suggests that mechanisms other than irritation dominate tretinoin-induced repair of photoaging in humans. Expand

TLDR
Once-daily application of tretinoin to photodamaged facial skin for 0-12 months results in substantial clinical and histologic improvement and the sum of changes is toward more youthful skin. Expand
Topical tretinoin for photoaged skin.
TLDR
It was concluded that topical tretinoin is capable of at least partly reversing the structural damages of excessive sunlight exposure and may be useful in decelerating the photoaging process. Expand
Topical retinaldehyde on human skin: biologic effects and tolerance.
TLDR
It is indicated that topical retinaldehyde has biologic activity and is well tolerated on human skin and allowed prolonged use in patients with inflammatory dermatoses. Expand
Topical tretinoin for treatment of photodamaged skin. A multicenter study.
TLDR
Clinical and histologic effects of a new emollient cream formulation of topical tretinoin at concentrations of 0.05% and 0.01% provide independent evidence supporting clinical improvement and side effects were usually mild and well tolerated. Expand
Application of retinol to human skin in vivo induces epidermal hyperplasia and cellular retinoid binding proteins characteristic of retinoic acid but without measurable retinoic acid levels or irritation.
TLDR
The data demonstrate that ROL application produces trace erythema not significantly different from vehicle, whereas RA causes ery thema, and does not significantly increase RA levels, compatible with the idea that R OL may be a prohormone of RA. Expand
Topical retinoic acid for treatment of solar damage
TLDR
There were significant improvements in fine wrinkling around the eyes, crease lines around the mouth and cheeks, wrinkling on the dorsum of the hands and yellow discoloration after 12 weeks of tretinoin cream treatment. Expand
