The Retinol 1% Serum is an advanced, high-performance formula designed for all skin types, including sensitive skin, dry skin, normal skin, oily skin, and combination skin.

Clinically Proven Results 

Tested in a 4-month clinical study, this serum demonstrated significant improvements by:

  • Smoothing wrinkles and fine lines
  • Reducing wrinkle length by 55%
  • Reducing wrinkle depth by 48%
  • Improving skin firmness by 41%

Scientifically Advanced Formula

At the core of this serum is 1% encapsulated pure retinol, a highly effective retinoid product designed to promote collagen production and cellular renewal. This delivers long-lasting, visible results by evening skin texture, improving uneven skin tone and refining pore size.

To minimize irritation, the formula includes a 2.5% neuropeptide, which helps reduce inflammation and strengthen the skin barrier. The 4.3% Dermaprotective D+ Soothing Complex, enriched with Shea Butter, Vitamin E, and Tocopheryl Acetate, further enhances skin’s soft texture while providing powerful antioxidant protection against environmental stress and radical damage.

The addition of pure, stable Vitamin C (ET-VC™) delivers brightening effects, reinforcing the skin’s natural defense against photo damage and oxidative stress.

Recommended For

  • Mature skin seeking improved firmness and elasticity
  • Sensitive skin in need of soothing ingredients and minimal irritation
  • Anyone incorporating Vitamin C serums into their skincare routine for a comprehensive beauty routine

How to Use 

Dermatologists agree: the best way to introduce retinol products is through a gradual integration process.

  • Apply to clean skin in the evening, avoiding the eye area.
  • Start by using it every other night, then gradually increase to once or twice daily depending on retinol tolerance.
  • Always follow with a moisturizer after retinol to maintain hydration and protect the skin barrier.
  • Retinol increases sun sensitivity, making it important to apply broad-spectrum U.V. sun protection with SPF 50 every morning to shield against sun damage.

Key Ingredients 

  • 1% Encapsulated Pure Retinol – Supports collagen production, refines texture, and enhances firmness.
  • 2.5% Neuropeptide – Helps regulate inflammation, improving skin tolerance and comfort.
  • 4.3% Dermaprotective D+ Soothing Complex – A blend of Shea Butter, Vitamin E, and Tocopheryl Acetate to strengthen the skin barrier.
  • Pure Vitamin C (ET-VC™) – Enhances antioxidant protection and brightens the complexion.

The Functionalab Advantage 

Functionalab’s exclusive science-backed formula is designed for highly stable, water-free solution retinol delivery, ensuring maximum absorption while minimizing irritation. The gradual-release technology allows the skin to adjust progressively, reducing the risk of persistent irritation or peeling.

Actually feels cool at night
Color: Light Gray, Size: Standard
I’ve been using these for several days now and I did notice a difference. I tend to get hot while sleeping, so I was curious if they would actually help, and they do feel cool when you lay on them. I also like that they’re soft and comfortable, not that weird texture some “cooling” products have. So far, I’ve been really happy with them.

Cool, Comfortable, and Worth Every Penny!
Color: Light Gray, Size: Standard
I’m honestly impressed with these pillowcases! From the first night, I could feel the difference—they stay noticeably cool, which is perfect if you tend to sleep hot like I do. The fabric feels silky smooth against the skin without being slippery, and it’s really gentle on both my hair and face. I’ve also noticed I wake up less sweaty and more comfortable overall. They fit my pillows well and don’t slip off during the night, which is a big plus. After washing, they held up great—no fading, shrinking, or loss of softness. If you’re looking for pillowcases that actually help keep you cool and comfortable through the night, these are definitely worth it. I’ll be buying more!

Extremely cold, silky, gentle on hair
Color: White, Size: Queen
This was so cold when I removed it from the package that at first I thought it would be too cold. It was as if it had been in a freezer. I really like how silky it is on my face. (I can't stand a rough feeling pillowcase.) It is also gentle on my curly hair. The pillowcase can warm up from being slept on, but a shift of just a few inches gets back to wonderful cold. I highly recommend this as an extremely cool, silky smooth fabric. These are much colder than my very expensive miracle sheets.

Freaking Amazing 🤩
I never write reviews but these pillow cases absolutely deserve one!!! These are absolutely amazing! So soft and cool! I sweat so bad every night!! I wake up and my hair, shirt and pillow are drenched!!! I slipped these bad boys on as soon as they came in, and let me tell you! They were cold to the touch, I woke up this morning and I wasn’t sweating! I thought $20 something dollars was a little expensive for 2 pillow cases but was totally worth it! We love love love them!🩷🩷🩷Hubby approved😉

Stretchy Material and Cooling Fabric
Color: Light Gray, Size: Standard, Color: Light Gray, Size: Standard
Material: is very stretchy and cools well. It has a zipper which is good because the fabric is very soft and slippery and if it didn’t have a zipper the pillow would not stay in the case. Durability: zipper works great and material is easy to clean. Color: I have the gray and my daughter has the pink. Both colors as advertised. Value: Good value and I got what I expected.
