Advanced Clinicals Retinol, Vitamin C & Collagen Serum Set 3×1.75 fl oz — Hydrating, Anti-Aging

Advanced Clinicals 3-piece serum set combines a retinol serum, vitamin C serum, and collagen serum to hydrate, brighten, and help improve the appearance of skin texture and firmness.

This curated trio pairs targeted actives—retinol, vitamin C with exfoliating acids, and a collagen-boosting hydrator—into one routine to address common cosmetic concerns such as uneven tone, loss of firmness, and visible fine lines. Each 1.75 fl oz bottle is formulated by cosmetic chemists and dermatologist tested, using well-known ingredients like hyaluronic acid, peptides, ferulic acid, and green tea to support a refreshed-looking complexion.

How does each serum fit into a daily skincare routine?

Use the serums in a layered routine to let each formula deliver its benefit without interference. Typically the vitamin C serum is applied in the morning for radiance and antioxidant support, while the retinol serum is used at night to support skin renewal; the collagen serum can be used morning and/or night for added hydration and smoothing.

• Morning: cleanse → collagen serum → vitamin C serum → moisturizer → SPF
• Night: cleanse → vitamin C (optional) → retinol serum → collagen serum → moisturizer
• Introduce retinol gradually to build tolerance and reduce irritation risk

What visible effects can I expect and when?

Results vary by individual, but with consistent use you can expect improvements in surface texture, brightness, and hydration over weeks to months. The vitamin C blend helps improve radiance and the look of uneven tone, the retinol supports smoother texture, and the collagen serum delivers immediate hydration for a plumper appearance.

• Immediate: increased skin hydration and smoother feel from hyaluronic acid and emollients
• 4–8 weeks: more even tone and reduced appearance of dullness from vitamin C and exfoliating acids
• 8+ weeks: improved texture and the look of fine lines with continued retinol use

Are these serums suitable for sensitive or mature skin?

The formulas incorporate both gentle hydrators and active ingredients; sensitive skin may tolerate them if introduced slowly and used with supportive moisturizers. Because retinol and exfoliating acids can cause irritation, start with lower frequency and perform a patch test before full-face application.

• Patch-test new serum on inner forearm 48 hours before regular use
• Begin retinol once or twice weekly, increasing frequency as tolerated
• Always pair with sunscreen during daytime to protect skin after actives

Which key ingredients are in the set and what roles do they play?

The set blends recognized cosmetic actives to address multiple skin goals: antioxidants and acids for radiance, retinol for texture, and humectants plus peptides for hydration and support. Each ingredient was chosen to complement the others in a balanced routine rather than as standalone treatments.

• Retinol serum: retinol, green tea, vitamin E for texture appearance and antioxidant support
• Vitamin C serum: vitamin C, ferulic, lactic and glycolic acids, peptides for brightness and exfoliation
• Collagen serum: hyaluronic acid, peptides, algae, vitamin E for hydration and smoothing

Who this set is for: This 3-piece Advanced Clinicals collection suits anyone seeking a compact, science-informed starter kit to address multiple skin concerns—dullness, crepey texture, and decreased firmness—without buying separate full-size products. It’s designed for men and women who want to build a layered routine using recognized actives, and for users who prefer dermatologist-tested, lab-formulated serums made with globally sourced ingredients.
