Photoaging is a common concern within the cosmeceutical industry with many products that are available. One frequently used product is hydroquinone that is used to even skin tone. However, hydroquinone has several shortcomings. The ingredient is controversial for its potential safety issues and it has been banned in Europe. An alternative ingredient that has emerged for its potential use is hexyresorcinol for evening skin tone. Additionally, hexylresorcinol may have other photoaging benefits such as the reduction in the appearance of fine lines.

Therefore, the aim of this study is to assess how hexyresorcinol may compare to the use of hydroquinone in the setting of photoaging.

Criteria

Inclusion Criteria:

Females aged 35-65 (limiting to females so that there is not heterogeneity with the influence of hormones. Also, females are a much larger user base of skin care products)
Individuals who have not participated in any other clinical studies using the same test sites (face) and hand in the past 14 days
Individuals with Fitzpatrick skin type I-IV
No known medical conditions that, in the investigator's opinion, may interfere with study participation.

Exclusion Criteria:

• Individuals who have been on any medication that has caused a change in skin pigmentation based on the opinion of the investigator

Individuals who have history of acute or chronic disease that would likely interfere with or increase the risk on study participation at the discretion of the investigator
Female volunteers who are pregnant or are actively breastfeeding or planning a pregnancy within two months. (There is no concern for risk to fetus but pregnancy can alter skin pigmentation)
Female volunteers who have started a new hormonal birth control agent or switched to a hormonal birth control agent within the past 60 days
Individuals who have had any medical or cosmetic procedure, such as laser resurfacing, or plastic surgery to the test site (face) within the last 6 months. This includes botulinum toxin, dermal fillers, collagen or other similar cosmetic procedure
Individuals who are currently using or during the past 30 days have used hydroquinone, or a retinoid such as Retin A, or other Rx/OTC Retinyl A.
