Ingredient Breakdown: What Makes SkinCeuticals Cell Cycle Catalyst Effective?

What Are the Key Ingredients in SkinCeuticals Cell Cycle Catalyst?

SkinCeuticals Cell Cycle Catalyst is powered by a 7.7-percent complex of alpha and beta hydroxy acids, known for their ability to reverse photodamage and improve wrinkles, elasticity, tone and hydration. This blend of exfoliating acids delivers a gentle multi-layer peeling to improve tone and texture, refine the look of fine lines and diminish discoloration.

AHAs are water-soluble acids that work on both the epidermal and dermal layers of the skin by loosening and breaking down the gluey substance that holds dead skin cells together, promoting cellular renewal through exfoliation, enhancing moisturization, reducing wrinkles and boosting collagen synthesis.

On the other hand, BHAs are lipid-soluble, which means they can penetrate even deeper into the skin to remove excess oil and pore-clogging dead skin cells. When used together in the same formula, AHAs and BHAs can deliver even better results.

“Together, they provide a comprehensive exfoliation, targeting both the surface and deeper skin layers. While both AHAs and BHAs are exfoliants, formulating them together in the right concentrations can offer a balanced exfoliation experience that minimizes potential irritation,” Holdorf adds.

Complementing this multi-acid complex is 1-percent taurine, a.k.a the new kid on the SkinCeuticals block of pharmaceutical-grade ingredients. Described by one study as a “very essential amino acid,” taurine has been found to hasten cell metabolism, regeneration and healing of damaged skin in an 2021 study examining the benefits of amino acid complex in cosmetic products. Some of the taurine benefits listed in its findings are:

• Maintaining cell hydration and balancing electrolytes
• Regulating immune system health and antioxidant functions
• Moisturizing and nourishing the skin’s surface layer from within

For Cell Cycle Catalyst, taurine plays a key role in the serum’s ability to enhance cellular energy and vitality, stimulate skin barrier renewal, maintain hydration and prevent trans-epidermal water loss.

What Are the Active Ingredients in SkinCeuticals Cell Cycle Catalyst?

One way that Cell Cycle Catalyst achieves its goal of accelerating cell turnover is through gentle and effective top-to-bottom exfoliation made possible by the collaborative interaction of the active ingredients in its hydroxy acid complex.

“Mixing AHAs and BHAs in one formula, like in SkinCeuticals Cell Cycle Catalyst, offers a synergistic approach to skin exfoliation and renewal,” explains Holdorf. “This dynamic duo works together to not only slough off dead skin on the surface with AHAs but also dives deep into your pores with BHAs to zap excess oil and fight blemishes. It can tackle everything from fine lines and wrinkles to acne and uneven texture, all while keeping your skin glowing and smooth.”

Making up this MVP acid complex are:

• 2% Phytic Acid: A gentle AHA with a dual-action mechanism (inhibiting melanin synthesis and melanin oxidation) known to brighten skin, improve dark spots and prevent free radical damage.  
• 1% Mandelic Acid: As a larger-sized molecule, mandelic acid penetrates the skin more slowly, allowing you to reap the exfoliating benefits of AHAs without causing inflammation and irritation, making it ideal to use with acne and hyperpigmentation treatment. 
• .2% Salicylic Acid: Widely used in skincare, salicylic acid has an established rep when it comes to treating and preventing acne, photodamage and other skin conditions. 
• 2% Lactic Acid: An extra-mild AHA that’s safe to use on all skin types and helps improve firmness and texture as well as wrinkles and fine lines. 
• 2.5% Glycolic Acid: Aside from facilitating natural exfoliation and surface skin renewal, research also shows that glycolic acid can aid in collagen synthesis.  

Rounding up Cell Cycle Catalyst’s list of active ingredients is taurine, a naturally occurring and anti-inflammatory amino acid found in skin that takes on a crucial role in maintaining cellular health and metabolism. Just like collagen, taurine levels decrease over time and can lead to visible signs of aging. Cell Cycle Catalyst’s high concentration of taurine counters this and ensures healthy skin cycling. 

According to Holdorf, taurine boasts of several impressive benefits that improve skin health. These include: 

• Maintaining optimal hydration by balancing the flow of water in and out of cells 
• Protecting the skin against free radical damage caused by UV rays, pollution and other external aggressors by acting as a potent antioxidant 
• Strengthening the skin’s protective barrier, which improves its ability to retain moisture and defenses against irritants and pathogens 
• Calming and soothing redness and inflammation for those with sensitive or irritated skin 

Taurine has also been found to play well with other equally powerful anti-aging ingredients, such as retinol, and can even enhance their benefits. “Retinol is a powerhouse ingredient known for its ability to promote cell turnover, boost collagen production and tackle signs of aging and acne. However, its potency can sometimes lead to irritation, especially in sensitive skin types,” Holdorf explains. “This is where taurine steps in. Its hydrating, soothing and barrier-repairing properties can help mitigate some of the potential side effects of retinol, such as dryness and irritation.”

“I added this serum to my skincare routine about two weeks ago. I wasn’t sure what to expect—but WOW! My skin is looking better than it has in a long time,” raves one Dermstore reviewer. “It seems to be just what the name suggests, a catalyst for cell turnover because my skin appears renewed after every time I use it. I’ve only applied it at night, but I wake up to refreshed skin. Definitely a keeper for my routine!”

Another user echoes this, saying, “My fine lines appear to look diminished, and the overall health of my skin barrier has improved greatly. I have layered it under occlusives as part of my nighttime skincare routine and my skin has taken an overall appearance of freshness and looks dewy. My pores appear smaller, and there are days that I have chosen not to even apply cosmetics.”

Safety Considerations Before Using SkinCeuticals Cell Cycle Catalyst

While Cell Cycle Catalyst is safe for daily use and for all skin types, it’s still important to adhere to some safety protocols before introducing a new product to your skincare routine. Here are some helpful tips to remember, according to Holdorf: 

• Patch test and observe your skin’s response. Apply a small amount of the product on a discreet area of your skin. Pay close attention to how your skin reacts, especially if you’re combining the product with other active ingredients. 
• Start slow. Allow your skin to adjust by introducing the product gradually to avoid overwhelming and irritating your skin. 
• Use sunscreen. Ingredients like AHAs and BHAs increase the skin’s sensitivity to the sun, so make sure to use broad-spectrum sunscreen and reapply as needed throughout the day. 
• Supplement hydration. Some skin types may not react well to exfoliating acids and can experience dryness and irritation. Soothing and hydrating ingredients (like hyaluronic acid, ceramides and niacinamide) support your skin barrier and provide added nourishment after using potent exfoliants. 
• Consult with professionals. Cell Cycle Catalyst is safe to use before and after treatment and in-office procedures. However, it’s always best to talk to skincare pros prior to adding any product to your regimen, especially if you have skin conditions or undergoing a procedure. Dermstore offers complimentary virtual consultations with estheticians who can advise on the best timing and usage to ensure compatibility with your treatments.
