The Top 5 Scientifically Proven Anti-Aging Ingredients

1

Retinoids (Vitamin A)

The gold standard in anti-aging. Decades of research prove retinoids stimulate collagen production, accelerate cell turnover, and improve skin texture.

Benefits:

  • • Reduces fine lines by up to 64%
  • • Improves skin elasticity
  • • Evens skin tone
  • • Minimizes pore appearance

How to Use:

  • • Start 2-3x per week
  • • Apply at night only
  • • Always use SPF during day
  • • Begin with low concentration
2

Vitamin C (L-Ascorbic Acid)

Powerful antioxidant that protects against environmental damage while boosting collagen synthesis and brightening skin.

Benefits:

  • • Neutralizes free radicals
  • • Stimulates collagen production
  • • Brightens hyperpigmentation
  • • Provides immediate radiance

Best Concentration:

  • • 10-20% L-ascorbic acid
  • • Morning application
  • • Stable derivatives available
  • • Store in cool, dark place
3

Peptides

Short chains of amino acids that signal skin cells to produce more collagen, elastin, and other proteins essential for youthful skin.

Key Types:

  • Palmitoyl tripeptide-1: Stimulates collagen and elastin
  • Acetyl hexapeptide-8: Reduces muscle contractions (Botox-like effect)
  • Copper peptides: Wound healing and anti-inflammatory
  • Matrixyl: Proven to reduce wrinkle depth
4

Niacinamide (Vitamin B3)

Multi-functional ingredient that improves skin barrier function, reduces inflammation, and addresses multiple signs of aging.

Proven Benefits:

  • • Reduces fine lines
  • • Minimizes pore appearance
  • • Improves skin elasticity
  • • Regulates oil production

Usage:

  • • 2-10% concentration
  • • Can be used twice daily
  • • Compatible with most ingredients
  • • Suitable for sensitive skin
5

Alpha Hydroxy Acids (AHAs)

Chemical exfoliants that remove dead skin cells, stimulate cell renewal, and improve skin texture and tone.

Most Effective AHAs:

  • Glycolic acid: Smallest molecule, deepest penetration
  • Lactic acid: Gentler, also hydrating
  • Mandelic acid: Largest molecule, most gentle
  • • Start with 5-10%, increase gradually

How to Combine Anti-Aging Ingredients

Safe Combinations:

  • • Vitamin C (AM) + Retinoid (PM)
  • • Niacinamide + almost anything
  • • Peptides + hyaluronic acid
  • • AHA/BHA + moisturizer

Avoid Mixing:

  • • Vitamin C + Retinoids (same time)
  • • AHA + BHA (for beginners)
  • • Multiple actives when starting
  • • High concentrations together
