solar shade chemical sunscreen texture

Everything to Know About Solar Shade Sunscreen Broad Spectrum SPF 46 PA++++

Solar Shade Sunscreen includes bioactives such as microalgae, ethyl ferulate, and rice phytomolecules that each provide unique support to skin exposed to solar radiation. Ethyl Ferulate, a derivative of ferulic acid, neutralizes the signs of external aggressors while soothing the skin. Antioxidant molecules extracted from black, red, and brown rice increase the skin’s tolerance and defense against oxidative stress caused by solar radiation and pollution. Microalgae rich in β-carotene and astaxanthin help reduce formation of reactive oxygen species that are known to accelerate photoaging.

Hyaluronic Acid Vs. Polyglutamic Acid

Hyaluronic Acid Vs. Polyglutamic Acid - Which Is Right For You?

Both hyaluronic acid and polyglutamic acid offer immediate and noticeable skin hydration but polyglutamic acid can further improve dry skin by aiding in the skin’s natural production of NMF. Polyglutamic acid and hyaluronic acid can even be used together or layered for further hydration and skin plumping as neither of these materials has known compatibility issues.

types of broad spectrum sunscreen

What is Broad Spectrum Sunscreen?

A sunscreen labeled with a broad spectrum claim indicates that it shields the skin from both UVA and UVB radiation, the two primary types of ultraviolet radiation that contribute to skin damage, premature aging, and skin cancer. Sunscreens that do not indicate broad spectrum only protect against UVB radiation and only have an SPF value on the packaging. Broad-spectrum sunscreens have the additional claim “broad spectrum” listed before the SPF value.

layering skincare products

How to Layer Your Skincare Products

While your individual routine may vary due to skin type, skin concern, time of the year, and hormonal fluctuations, the basics of layering stay the same. You layer or apply products by format first then by water solubility and thickness. The below is a guideline on how to layer products, referencing Prequel products, but is not necessarily a proposed routine. Prequel products were created as stand alone products that can be seamlessly introduced to your skincare routine. Not every step or every Prequel product may be appropriate for your skin. A routine composed of various product combinations is very personal and at Prequel we hope to offer you the tools to customize your skincare needs.

prequel national rosacea seal acceptance

Our Products That Received the National Rosacea Society Seal of Acceptance

We are pleased to announce that a number of our Prequel SKUs have been awarded the new National Rosacea Society Seal of Acceptance. The National Rosacea Society (NRS) publicly announced the launch of the seal and the rigorous process necessary to incorporate the seal on applicable skincare products. The aim of the seal is to aid those suffering with rosacea or have been diagnosed with rosacea-prone skin in selecting personal care products that will not exacerbate symptoms or contribute to flare-ups. While products awarded the seal are not meant to treat or heal the signs and symptoms of rosacea, a medical condition that affects 1 in 20 Americans according to the NRS, they are meant to minimize the chance of irritation or sensitization for those with rosacea. Our brand founder, Dr. Sam Ellis, is the one out of 20 with diagnosed rosacea and feels passionately about offering products that consumers with rosacea-prone skin feel comfortable using. Criteria for Acceptance The Prequel products submitted for the NRS Seal of Acceptance passed the stringent criteria for acceptance identified below. Formula Review Rosacea has diagnostic features that include papules and pustules, facial flushing, visible blood vessels called telangiectasia, and persistent erythema. Ingredients in products should not exacerbate these symptoms so part of the criteria for seal acceptance is that the products must be free of ingredients that may cause damaged skin barrier function, vasomotor instability (flushing), or unwanted neurosensory stimulation (burning, itching). A panel of board certified dermatologists scrutinized and assessed every ingredient in the products to make sure the ingredients passed these qualifications. We provided not only quantitative ingredient lists for products but supported our products with toxicological risk assessment reviews to further validate the safety of the products. Repeated Insult Patch Test (RIPT) In addition to a review of the ingredients in the products, each Prequel product submitted for the seal underwent third party clinical testing. The first clinical test was the industry standard Repeated Insult Patch Test (RIPT) to evaluate skin irritation and sensitization. The NRS requires products to be hypoallergenic, a non-regulated term but per industry standards does have an established protocol. Products were tested on 200 panelists, 50% of which had self-perceived sensitive skin with the primary investigator of the study being a board certified dermatologist. Learn more about the process and the dermatologist-tested claim. Safety-In-Use Testing Once the products passed this initial safety test, they were then evaluated through a Safety-In-Use test. RIPT tests irritation and sensitization potential through patch testing on the back or forearm under occlusive conditions. Safety-In-Use testing evaluates the products for irritation and sensitization as a consumer would use the product, better reflecting real time use. While safety-in-use testing is not a unique study, the NRS requires this test to be performed solely on diagnosed rosacea patients under the care of a board certified dermatologist. The dermatologist investigator reviews tolerability of the products which includes evaluating the skin for dryness, desquamation, erythema, edema, and irritation. Suitability is also included encompassing skin facial erythema and facial inflammatory papules/pustules. Participants also assess the tolerability and suitability providing their feedback on dryness, peeling, tingling, stinging, itching, burning, facial redness, flushing/blushing severity, flushing/blushing frequency, and facial acne. Our Prequel products were tested as a regimen starting with our Prequel Gleanser Non-Drying Glycerin Cleanser and building upon weekly with additional Prequel products ending with our Prequel Sun Barrier Mineral Sunscreen Broad Spectrum SPF 50 PA++++. The dermatologist, Dr. Zoe Draelos, who serves on the board of directors for the NRS and is a clinical and research dermatologist, determined from the data that all study products reduced the severity of both erythema and acne lesions making them suitable for rosacea sufferers. The test subjects also noted a remarkable improvement in rosacea signs as a result of the skin care regimen. While each product produced favorable data there was a cumulative effect using all the products as a whole. Not all Prequel products tested have launched yet so stay tuned; however, we can share the data obtained from the Gleanser alone. After 1 week twice daily use of Gleanser, participants with diagnosed rosacea saw statistically significant improvement in visual rosacea signs including 26% reduction in redness, 27% reduction in flushing severity, and 38% reduction in facial acne. Products that obtain the NRS Seal of Acceptance are not meant to treat or heal rosacea but guide those suffering with rosacea to products that are hypoallergenic, non-acnegenic, non-inflammatory, non-sensitizing and ultimately safe to use for their rosacea-prone skin. We are excited to be one of the first brands to pursue the seal and offer products that are safe for those suffering with rosacea.

The inclusion of a product in the Seal of Acceptance program does not represent an endorsement of that product by the NRS. The Seal of Acceptance for a skin care or cosmetic product means it has been evaluated by an independent panel of dermatologists to determine that it does not contain ingredients that are known to be generally unsuitable for use by people with sensitive rosacea skin. Rosacea may vary substantially from one patient to another. The NRS Seal of Acceptance does not guarantee that individuals will not experience adverse reactions after using a product bearing the Seal. The NRS Seal of Acceptance does not guarantee that the product will improve an individual’s rosacea. All individuals with rosacea should consult with a healthcare provider to confirm that using any over-the-counter product bearing the Seal of Acceptance will not interfere with prescribed medications or therapy.
