6 Ingredients That Actually Work

NiacinamideBrightening

Reduces pores, fades hyperpigmentation, strengthens the skin barrier. Works for all skin types.

Hyaluronic AcidHydration

Draws moisture into the skin. Lightweight — great for oily skin. Apply to damp skin for best results.

Retinol (Vitamin A)Anti-Aging

Accelerates cell turnover, reduces fine lines and acne. Start slow — 1-2x per week at night only.

Vitamin CAntioxidant

Protects against UV damage, brightens skin, boosts collagen. Use AM, followed by SPF.

AHA/BHA AcidsExfoliation

Glycolic (AHA) resurfaces texture. Salicylic (BHA) unclogs pores. Never use with retinol same night.

CeramidesBarrier Repair

Restore and maintain the skin barrier. Essential for dry or sensitive skin types.

Ingredients to Watch Out For

Fragrance / Parfum

Top cause of contact dermatitis and sensitization — especially for sensitive skin.

Alcohol Denat

Drying and irritating. Often used in toners — damages the moisture barrier over time.

Sodium Lauryl Sulfate

Harsh surfactant that strips natural oils. Look for SLS-free cleansers.

Parabens (in high doses)

Preservatives with potential hormonal disruption — choose paraben-free where possible.

Safe vs. Dangerous Combos

Retinol + AHAs/BHAs⚠️ Avoid same night

Both exfoliate — combining causes over-exfoliation and irritation.

Vitamin C + Niacinamide✅ Safe together

Old myth — they're compatible and even complementary.

Retinol + Vitamin C⚠️ Use separately

C in AM, retinol at PM — both effective independently.

Hyaluronic Acid + Anything✅ Always safe

Works as a base layer under most actives.
