This is a beautiful, hydrating skincare product for the evening. The packaging is clearly well-made and the product is a beautiful light blue/periwinkle shade. The texture is very nice -- it is not as thick as some "night creams" but it is definitely deeply hydrating and luxurious feeling. There is no strong scent, which is a requirement for my skincare products personally. My skin is normal and I have sensitive skin on my neck -- I am prone to eczema there, and this has not irritated my neck skin at all so far!! So far I would definitely recommend this product.

This product is so wonderful. I generally have sensitive skin, so not a lot of products agree with my skin. But this is so soothing and restorative. It's deep moisture makes me wake up with such glowy look

Hydrates dry skin
I tend to have dry skin and I feel this product does a great job locking in moisture overnight and allowing you to wake up with hydrated skin.

This is IT! I've never used a nighttime moisturizer like this. The texture is so cool, and the way my skin feels in the morning is unmatched. Bouncy, nourished and so moisturized.

AMAZING!
Absolutely great product. I truly love the texture of this product -- so lightweight but you can still feel it on your skin when you apply. I noticed a difference in my skin texture and has brightened my face.

Clinical Study
A clinical study for skincare is a scientific research method that evaluates the safety and effectiveness of products, treatments, or ingredients under controlled conditions. These studies are designed to provide evidence-based results about how skincare products perform when used by real people. Clinical studies are not legally required and most brands opt out, due to cost, time, risk and marketing preference.
Consumer Perception Study
A consumer perception study for skincare is a type of market research that focuses on gathering subjective feedback from actual consumers about their experience using skincare products. Unlike clinical studies that emphasize objective measurements, consumer perception studies prioritize how users feel about and perceive the product's performance.
Fitzpatrick Scale
The Fitzpatrick scale is a numerical classification system used to categorize human skin color and its response to ultraviolet (UV) radiation. Developed in 1975 by Thomas Fitzpatrick, a Harvard dermatologist, it's widely used in dermatology, cosmetics, and skincare to determine appropriate treatments and product recommendations. The Fitzpatrick scale helps dermatologists assess skin cancer risk, determine appropriate laser treatment settings, guide sunscreen recommendations, and customize skincare regimens. In clinical studies, it's an essential tool for ensuring diverse participant selection and analyzing how treatments perform across different skin types.
Fitzpatrick Skin Types
The scale consists of six types:
Type I: Ivory skin that always burns, never tans
Type II: Fair skin that burns easily, tans minimally
Type III: Medium skin that sometimes burns, gradually tans
Type IV: Olive skin that minimally burns, tans easily
Type V: Brown skin that rarely burns, tans darkly
Type VI: Deep brown to black skin that never burns, always tans
Peer Reviewed
"Peer reviewed" in a dermatological clinical trial means that the study and its results have undergone evaluation by independent experts in dermatology before being published or presented. This review process is a critical quality control step that helps ensure the research is scientifically sound. It is a higher level of scientific credibility since the findings have been scrutinized and validated by objective third-party experts.
Research Gap
The diversity research gap in dermatology refers to the significant underrepresentation of diverse skin types and ethnicities in dermatological research and clinical studies. This gap has created disparities in how skin conditions are diagnosed, treated. For skincare brands, addressing this research gap represents both an ethical responsibility and a business opportunity. By conducting inclusive clinical testing that encompasses the full range of skin types and ethnicities, brands can develop more universally effective products while also contributing to closing this significant knowledge gap in dermatological science. This commitment to diverse research helps ensure products work effectively for all consumers while advancing more equitable skincare science.
White Paper
A white paper in dermatology is a specialized document that provides in-depth, evidence-based information about dermatological conditions, treatments, research findings, or clinical methodologies. For a skincare company, a dermatology white paper might present clinical study results for a product line, explain the scientific mechanism behind a proprietary ingredient, or discuss the effectiveness of specific formulations for different Fitzpatrick skin types.
