What Actually Works and When to Use It
Walk down any skincare aisle (or scroll Instagram for five minutes), and you’ll get hit with a whirlwind of buzzwords: retinol, peptides, vitamin C, niacinamide, hyaluronic acid… it's enough to make your head — and your face — spin.
So what actually works? And when should you use it?
Let’s cut through the noise and get to the truth.
Meet the MVPs of Modern Skincare
Here’s what each of these buzzwords really means — and why they matter.
🧬 Retinol: The Resurfacer
What it does: Speeds up cell turnover, improves skin texture, boosts collagen, fades dark spots, unclogs pores. Best for: Aging skin, acne-prone skin, rough texture, fine lines
When to use:
Evening only
Start slow (2–3x/week), then increase as tolerated
Always follow with moisturizer
NEVER skip sunscreen during the day
Pro Tip: PCA SKIN’s Intensive Clarity Treatment is a game changer — combining retinol with acne-fighting salicylic acid.
💉 Peptides: The Builders
What they do: Signal the skin to produce more collagen and elastin (basically, they’re like little cheerleaders for your skin cells). Best for: Firmness, elasticity, and reducing signs of aging
When to use:
Morning or night
Great layered under a moisturizer
Try: Nouve Peptide Eye Gel-Cream — firming, smoothing, and designed for delicate under-eye skin.
☀️ Vitamin C: The Brightener
What it does: Fights free radicals, evens out skin tone, boosts collagen production, and helps prevent pigmentation. Best for: Dull skin, sun damage, dark spots
When to use:
Morning — under SPF
Don’t mix with strong exfoliants or retinol
Try: Nouve Vitamin C Serum — formulated for daily use and gentle enough for most skin types.
🌊 Hyaluronic Acid: The Hydrator
What it does: Pulls moisture into the skin and helps plump fine lines. Best for: Everyone — especially dry, dehydrated, or mature skin
When to use:
AM + PM
Apply to damp skin and lock it in with moisturizer
Try: Nouve Skin Firming Serum with Hyaluronic Acid, DMAE & CoQ10 — extra firming bonus.
💡 Niacinamide: The Multitasker
What it does: Reduces redness, regulates oil, improves tone, calms irritation, boosts barrier strength. Best for: Sensitive skin, oily skin, enlarged pores, and just... everything
When to use:
Morning or night
Pairs well with most actives
Try: Nouve 10% Niacinamide Serum — calming, brightening, and barrier-friendly.
So How Do You Put It All Together?
Here’s a quick cheat sheet:
Morning Routine
Cleanser
Niacinamide or Vitamin C Serum
Peptide Eye Gel-Cream
Moisturizer
SPF (EltaMD all day!)
Use Vitamin C if your focus is brightening and tone. Use Niacinamide if your skin is sensitive or prone to redness.
Evening Routine
Cleanser
Niacinamide or Peptides (if you’re taking a break from retinol)
Retinol (PCA) – a few nights per week
Moisturizer or Tallow Cream (Nouve)
Optional: Face oil or Recovery Cream to seal in hydration
Final Thought:
Skincare isn’t about using everything — it’s about using the right things at the right time.
With Nouve’s gentle actives, PCA’s pro-level treatments, and EltaMD’s sun-smart protection, you’ve got all the pieces you need to build a results-driven routine without overwhelming your skin (or your brain).
And remember: Always patch test new products. And when in doubt? Consult your dermatologist or skincare professional.
