Does Covey Sleep Tight Bakuchiol Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Covey Sleep Tight Bakuchiol Serum:

  • Significant moisturizing. It has a moisturizing rating of 6.5 out of 10.
  • Considerable anti-wrinkle efficacy: Covey Sleep Tight Bakuchiol Serum has an anti-wrinkle rating of 4.5 out of 10, indicating a moderate ability to reduce wrinkles.
  • Antioxidant protection.

Lightweight moisturizer perfect for oily to normal skin

According to CreamScan analysis, Covey Sleep Tight Bakuchiol Serum is highly moisturizing, with a moisturizing rating of 6.5 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Propanediol (est. ≈11.0%) and Glycerin (est. ≈4.0%), and a moderate occlusivity of 3.0 out of 10, solely because of the high content of Squalane (est. ≈6.0%).

This type of moisturizer is ideal for people with oily skin who want maximum hydration in a relatively lightweight, non-greasy formula. It combines a significant amount of humectants with a limited amount of occlusive ingredients to boost moisturizing efficacy without feeling too heavy.

This product may also be a good choice for people with normal skin who prefer fast-absorbing textures, as it balances significant moisturizing potential with a relatively lightweight texture.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Considerable anti-wrinkle efficacy

According to CreamScan analysis, Covey Sleep Tight Bakuchiol Serum has a moderate anti-wrinkle rating of 4.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈3.0%), 
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
Among others, Covey Sleep Tight Bakuchiol Serum also contains Bakuchiol, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Bakuchiol provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not contribute to the anti-wrinkle rating.
 
Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.
 

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Rich in skin-protecting antioxidants

We estimate that Covey Sleep Tight Bakuchiol Serum is rich (> 3%) in antioxidants, specifically Bakuchiol (est. ≈45.0%) and Niacinamide (est. ≈3.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

Ingredients explained

Bakuchiol
Est. %45
Function
Origin
BakuchiolA newly discovered bioactive obtained from the seeds of Babchi. It boosts collagen production like retinol, but with fewer side effects. Its effects include reduced wrinkles and faded pigmentation.
Water
Est. %22
Function
Origin
WaterThe most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Propanediol
Est. %11
Function
Origin
PropanediolAn excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
Squalane
Est. %6
Function
Origin
SqualaneAn occlusive moisturizing and emollient compound that forms part of the skin’s sebum. The main source of squalane had always been shark liver. Now, however, it is manufactured synthetically or derived from plant oils, such as olive and peanut oil.
Glycerin
Est. %4
Function
Origin
Glycerin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Niacinamide
Est. %3
Function
Origin
Niacinamide

Also known as vitamin B3, this ingredient is a true superstar with confirmed moisturizing, anti-acne, hyperpigmentation, and antioxidant benefits. Two studies confirm its significant anti-wrinkle efficacy.

Polymethylsilsesquioxane
Est. %2
Function
Origin
PolymethylsilsesquioxaneA type of spherical powder that functions on a ball-bearing effect in which the tiny microspheres roll around on the skin and create lubricity. Polymethylsilsesquioxane offers extra slip to skincare products and makes the skin feel soft and smooth.
Pentylene Glycol
Est. %1.5
Function
Origin
Pentylene Glycol

A naturally or synthetically derived preservative that exhibits effective antifungal and antibacterial traits. It also acts as a booster for more traditional preservatives. Pentylene glycol can also serve as a moisturizing humectant and solvent.

Sodium Polyacryloyldimethyl Taurate
Est. %1
Function
Origin
Sodium Polyacryloyldimethyl Taurate
Sorbitan Laurate
Est. %0.3
Function
Origin
Sorbitan LaurateSorbitan laurate is a sugar-based emulsifier similar to sucrose palmitate. It keeps oil broken into small droplets throughout water because of its chemical shape and nature (this is how most oil-in-water emulsifiers work by the way). These kinds of emulsifiers are mild enough to even be used in food preparations.
Xanthan Gum
Est. %0.3
Function
Origin
Xanthan GumA natural multi-functional ingredient that originates from fermented sugars. Xanthan gum acts as a viscosity-building agent to thicken skincare products. It is also an excellent stabilizer and works well to hold other ingredients together.
Hydrolyzed Hyaluronic Acid
Est. %0.3
Function
Origin
Hydrolyzed Hyaluronic AcidA smaller-molecule version of the regular hyaluronic acid. It is a powerful humectant that absorbs into the skin and offers moisturizing, smoothing, and anti-wrinkle effects. It is also slightly anti-inflammatory and displays subtle antioxidant properties.
Tetrasodium Glutamate Diacetate
Est. %0.3
Function
Origin
Tetrasodium Glutamate DiacetateA biodegradable chelating agent that chemically captures the heavy metal ions naturally present in water and disarms their harmful effects.
Silica
Est. %0.3
Function
Origin
SilicaA widely used cosmetic ingredient with the same chemical composition as the sand found on beaches. A common function of silica is its ability to control viscosity. In certain chemical forms, it can effectively thicken cream-style products.
Polyglyceryl-4 Laurate
Est. %0.3
Function
Origin
Polyglyceryl-4 Laurate
Dilauryl Citrate
Est. %0.3
Function
Origin
Dilauryl Citrate
N-Prolyl Palmitoyl Tripeptide-56 Acetate
Est. %0.3
Function
Origin
N-Prolyl Palmitoyl Tripeptide-56 Acetate
Citric Acid
Est. %0.3
Function
Origin
Citric AcidA gently exfoliating AHA that helps to remove the top layer of dead skin cells. In comparison to other AHAs, citric acid has been shown to be one of the least effective. It is also very commonly used as a stabilizing and pH-controlling agent.
Phenethyl Alcohol
Est. %0.3
Function
Origin
Phenethyl AlcoholA multifunctional ingredient that primarily serves as a preservative. Derived from the Chinese cinnamon tree, it provides broad-spectrum protection for skincare products through its antimicrobial efficacy.
Caprylyl Glycol
Est. %0.3
Function
Origin
Caprylyl GlycolAn emollient that improves product spreadability and offers a silky feel on the skin. It also acts as a preservative booster that improves the efficacy of other preservatives. According to the manufacturer, it is also a humectant moisturizer.
