SkinCeuticals Cell Cycle Catalyst

Why aestheticians love it: As skin ages, cell turnover slows down, which can manifest as visible signs of aging and also reduce receptivity to anti-aging serums and treatments. SkinCeuticals Cell Cycle Catalyst works to remove skin cell build-up to improve product penetration, boost cellular vitality, stimulate barrier renewal and maintain optimal hydration levels.

How it works: A 7.7% multi-acid blend consisting of 2% phytic acid, 1% mandelic acid, .2% salicylic acid, 2% lactic acid and 2.5% glycolic acid provides a multi-layer action to gently peel and accelerate skin renewal cycles while 1% taurine helps to boost cellular vitality. These ingredients work synergistically together to amplify product penetration of the rest of your skin care routine while helping to stimulate skin barrier renewal and maintain skin’s optimal hydration levels.

Who it’s for: This formula is ideal for all skin types, even sensitive skin, and is great for those who want to boost the overall efficacy of their anti-aging skin care products and treatments, including retinol.

Clinical results: After eight weeks, SkinCeuticals Cell Cycle Catalyst decreases the appearance of fine lines by 21%, decreases the appearance of visible discoloration by 16% and increases radiance by 16%.

How to use it: Apply a thin layer to clean, dry skin once or twice daily. If using in the morning, apply prior to your favorite SkinCeuticals vitamin C serum and end with a SkinCeuticals broad-spectrum sunscreen.

SkinCeuticals Silymarin CF Vitamin C Serum

Why aestheticians love it: This powerful oil-free vitamin c antioxidant serum is specifically formulated for oily and blemish-prone skin. It protects against environmental damage, reduces oiliness and helps prevent breakouts. How it works: A combination of 15% pure vitamin C, 0.5% silymarin (milk thistle extract), 0.5% ferulic acid and 0.5% salicylic acid neutralizes free radicals and helps prevent oil oxidation that can lead to breakouts. This patented formula is clinically proven to improve skin clarity, radiance and uneven skin tone.

Who it's for: Best suited for oily, combination, and acne-prone skin. Clinical results: After eight weeks, SkinCeuticals Silymarin CF clinical studies show 27% reduction in blemishes, 38% improvement in skin texture and 25% improvement in skin clarity.

How to use it: Apply four to five drops to a dry face, neck and chest every morning after cleansing. Afterwards, you can end your morning routine with your favorite SkinCeuticals broad-spectrum sunscreen.

SkinCeuticals Discoloration Defense

Why aestheticians love it: This layerable daily dark spot-correcting serum is clinically proven to reduce the appearance of visible discoloration—including hard-to-treat forms such as stubborn brown patches and post-acne marks—for brighter, more even-looking skin.

How it works: SkinCeuticals Discoloration Defense features 3% tranexamic acid, 1% kojic acid, 5% niacinamide and 5% HEPES. Together, they form an optimized cocktail of anti-discoloration ingredients that works synergistically to even skin tone and reduce the appearance of discoloration in as few as two weeks. This blend of ingredients improves brightness and helps to minimize the recurrence of discoloration with continued use.

Who it's for: All skin types and all skin tones struggling with discoloration, dark spots, post-acne marks or uneven skin tone.

Clinical results: A twelve-week clinical study showed an average improvement in the appearance of stubborn brown patches by 60%, 59% average improvement in the appearance of skin discoloration and 81% improvement in the appearance of post-acne marks.

How to use it: Twice daily, apply three to five drops to the face. If using in the morning, apply after a SkinCeuticals vitamin C serum and end with a SkinCeuticals broad-spectrum sunscreen.

SkinCeuticals Retexturing Activator Exfoliating + Hydrating Serum

Why aestheticians love it: SkinCeuticals Retexturing Activator is a revolutionary exfoliating, replenishing and resurfacing serum that helps reinforce the skin’s barrier for more radiant, healthy looking skin.

Key ingredients: Hydroxyethyl urea/aminosulfonic acid compound helps to break down the bonds between dead skin cells and the skin to maintain moisture within the skin’s surface while evenly exfoliating the surface. Kombucha and hyaluronic acid are also included to promote smooth, radiant skin.

Who it's for: Suitable for all skin types, especially sensitive, this oil-free exfoliating serum has the resurfacing power of a daily 20% glycolic acid treatment to retexturize and exfoliate for noticeably soft, smooth, skin texture.

How to use it: Twice daily, apply four to six drops to your face, neck and chest. If using in the morning, apply it after a SkinCeuticals vitamin C serum and end with a SkinCeuticals broad-spectrum sunscreen.

While SkinCeuticals' star products are certainly worth the hype, you won’t want to miss out on these hidden gems that can be seamlessly layered into your daily routine. As a general rule of thumb, apply your products in order of thinnest to thickest, in terms of consistency.
