Your guide to SkinCeuticals serums

This is sponsored content provided by skin care brand SkinCeuticals.

At the heart of an effective regimen lies the serum step- a targeted formula designed to address unique skin concerns and needs. SkinCeuticals understands this perfectly, offering a range of serum options that are lightweight, highly concentrated, and easy to layer.

But with an extensive list of options, how do you find the perfect match for your skin? In this comprehensive guide, we’ll break down a few of our favorite SkinCeuticals serums so that you can choose the best formula, or formulas, to add to your daily skin care routine.

SkinCeuticals Cell Cycle Catalyst Skin Surface Renewal Serum for dullness & uneven texture

As we age, our natural cell turnover slows down, which can result in a lackluster-looking complexion. This slowdown can affect how our skin responds to anti-aging serums, treatments and in-office procedures.

SkinCeuticals Cell Cycle Catalyst Skin Surface Renewal Serum is a super lightweight, layerable serum that’s designed to deliver a gentle, multi-level peel while helping to boost cellular energy. This formula is suitable for all skin types, even sensitive skin, and works to visibly improve the complexion overall for a smoother, brighter look.

Best for: All skin types who want to boost the anti-aging results of their at-home skin care routine, prep for an in office chemical peel, or for those who cannot tolerate retinoids and want a formula to accelerate skin cell turnover without irritation.

Key benefits: Amplifies visible results of anti-aging regimens and is clinically shown to help decrease the appearance of fine lines by up to 21% after twelve weeks.

Pro tip: To boost the anti-aging results of your skin care routine, apply Cell Cycle Catalyst once daily either in the morning or evening right after cleansing and before any other actives and serums.

SkinCeuticals Blemish + Age Defense Salicylic Acid Serum for adult acne & visible signs of aging

Formulated with a blend of dioic acid, salicylic acid and LHA, this oil-free serum helps decongest pores, minimize blemishes, and improve visible skin clarity. SkinCeuticals Blemish + Age Defense Salicylic Acid Serum is an effective serum that targets both adult acne and visible signs of aging in one formula.

Best for: Ideal for combination/oily skin types, acne-prone skin, congested skin and rough texture

Key benefits: In an eight-week study, Blemish + Age Defense significantly improved the appearance of fine lines, wrinkles and skin texture with up to 50% improvement in inflammatory blemishes.

Pro tip: Pair with SkinCeuticals Silymarin CF Vitamin C Serum for even better anti-aging and blemish reducing benefits.

SkinCeuticals Discoloration Defense for stubborn dark spots

This daily-use serum is designed to visibly reduce the appearance of dark spots, post-acne marks and discoloration. Formulated with tranexamic acid, niacinamide and kojic acid, SkinCeuticals Discoloration Defense supports a more even-looking complexion for all skin tones.

Best for: All skin types and tones concerned with discoloration and uneven skin tone.

Key benefits: Clinical testing shows up to 60% improvement in the appearance of stubborn dark patches after twelve weeks.

Pro tip: Pair with SkinCeuticals Phloretin CF Antioxidant Vitamin C Discoloration Serum and SkinCeuticals Daily Brightening UV Defense Sunscreen SPF 30 for even more color-correcting power.

SkinCeuticals P-TIOX Wrinkle Modulating Peptide Serum for dynamic wrinkles

This next-generation serum is powered by an advanced peptide complex, PHA, niacinamide and laminaria extract. Inspired by the effects of in-office neurotoxin injections, SkinCeuticals P-TIOX Wrinkle Modulating Peptide Serum is designed to soften the look of wrinkles caused by repeated muscle contractions.

P-TIOX is physician-tested to complement neurotoxin injections, but is effective on its own to achieve needle-free wrinkle correction without the aid of professional injectables.

Best for: All skin types concerned with fine lines, wrinkles and dullness.

Key benefits: Clinically proven to reduce the appearance of nine types of expression lines and reveal glass skin radiance.

Pro tip: Apply twice daily for best results, including around the eye area.

SkinCeuticals HA Intensifier Multi-Glycan Multi-Dimensional Volumizing Serum for volume loss & dehydration

Glycans, like hyaluronic acid, are responsible for giving skin structure and restoring visible plumpness. As we age, skin glycan levels decline, resulting in loss of facial volume and dehydration. SkinCeuticals HA Intensifier Multi-Glycan Multi-Dimensional Volumizing Serum is clinically shown to help stimulate glycans responsible for volume for skin that is instantly plumped and rehydrated.

Best for: All skin types experiencing loss of facial volume and lack of plumpness.

Key benefits: Instantly plumps skin and improves radiance by up to 10%. Clinically shown to visibly plump skin’s surface with volume equivalent to 1cc of hyaluronic acid after twelve weeks.

Pro tip: Massage and press into the face, neck and chest for daily youthful volume. HA Intensifier Multi-Glycan is physician tested to complement dermal filler injections.

SkinCeuticals A.G.E. Interrupter Ultra Serum for loss of elasticity & sagging skin

Collagen decline, glycation and rapid weight loss are all factors that contribute to thinning, sagging skin. SkinCeuticals A.G.E. Interrupter Ultra Serum is clinically proven to help lift and tighten skin by addressing collagen decline in the skin. This silky serum can be applied from face to neck, is suitable for all skin types, tested on GLP-1 patients and is physician tested to complement in-office ultrasound procedures.

Best for: All skin types experiencing sagging and loss of elasticity due to collagen decline in the skin.

Key benefits: Clinically shown to visibly tighten four key areas, including forehead, cheeks, jawline and neck.

Pro tip: Pair SkinCeuticals A.G.E. Interrupter Ultra Serum with SkinCeuticals A.G.E. Interrupter Advanced Corrective Cream to visibly reduce skin laxity in just four weeks.

Layering 101

If you have more than one skin concern, you might find that layering multiple corrective serums can help you achieve your goals. For best results, when layering more than one serum, apply in order from thinnest to thickest in terms of consistency. There is no need to wait too long in between steps either; you can wait just thirty seconds or until you feel the serum is absorbed, then move on to your next step!
