5-Step Routine
Rule 1: Thin to Thick
Follow this orderApply products from thinnest to thickest consistency. Watery products first, oils and creams last.
Rule 2: Water Before Oil
Water firstWater-based products penetrate better and should go before oil-based ones, which are occlusive.
Rule 3: Low pH First
Actives firstpH-dependent actives (vitamin C, AHAs, BHAs) work best at lower pH, so apply first after cleansing.
Rule 4: Separate Conflicting Actives

Rule 5: SPF Always Last (AM)
Last step AMSunscreen should be the final step in your morning routine to form a protective barrier.
Pro Tips
- 💡Wait 30-60 seconds between layers for absorption
- 💡Don't mix: retinol + AHAs/BHAs (irritation), benzoyl peroxide + retinol (deactivation)
- 💡Safe to mix: niacinamide + almost everything, hyaluronic acid + everything
- 💡If a product pills, you're either applying too much or not waiting enough between layers
- 💡Apply to damp skin for better penetration of hydrating products
- 💡When in doubt, simpler is better—you don't need 10 products
Key Ingredients
Vitamin C
Vitamin C (L-ascorbic acid) is a powerful antioxidant that brightens skin, fades dark spots, protects against free radical damage, and boosts collagen production.
Retinol
Retinol is a form of vitamin A that accelerates cell turnover, stimulates collagen production, and is considered the gold standard for anti-aging. It's available over-the-counter in various strengths.
Niacinamide
Niacinamide (vitamin B3) is a versatile ingredient that strengthens the skin barrier, reduces inflammation, minimizes pores, and regulates oil production. It's gentle enough for most skin types.
Hyaluronic Acid
Hyaluronic acid is a humectant that can hold up to 1000x its weight in water. It occurs naturally in skin and is used in skincare to provide deep, lasting hydration.
