Frequently Asked Questions

What skincare ingredients should you use in your 20s vs. your 40s?

In your 20s, focus on Vitamin C for brightness, niacinamide for barrier strength, and light hydration with hyaluronic acid. In your 40s, shift to retinol or bakuchiol for cell turnover, peptides for collagen support, ceramides for barrier repair, and richer moisturizers that address deeper dryness. SPF is non-negotiable at every age.

What skincare do tweens and teens actually need?

Tweens need simple, gentle products: a mild cleanser, light moisturizer, and SPF. For teens dealing with breakouts, niacinamide and natural salicylic acid address oil and congestion without the harshness of benzoyl peroxide. Avoid anything with synthetic fragrance, parabens, or physical scrubs at this age—the skin barrier is still developing.

What ingredients should you start using in your 30s to prevent aging?

The 30s are when collagen production starts to slow, so prevention becomes important. Add Vitamin C to protect against environmental damage, start a gentle retinol or bakuchiol for cell renewal, use peptides to support collagen, and prioritize hydration with ceramides and hyaluronic acid. Consistent SPF use is the single most impactful anti-aging habit.

Is non-toxic skincare actually effective or does it sacrifice results?

Non-toxic skincare is highly effective when formulated with proven active ingredients like niacinamide, Vitamin C, AHAs, bakuchiol, and peptides. The difference is sourcing these actives from clean, non-synthetic bases rather than mixing them with hormone disruptors and preservatives. Many conventional actives have clean-formulation equivalents that perform equally well or better.

What skincare ingredients should you avoid at every age?

Synthetic fragrances, parabens, phthalates, sulfates, and formaldehyde-releasing preservatives should be avoided at every stage of life. For younger skin especially, avoid benzoyl peroxide (harsh and sensitizing), physical micro-tear scrubs, and heavy silicones that block pores. The younger you start avoiding these, the healthier your skin's long-term trajectory.
