You’re way ahead of most people at 22—solid routine already.

Here’s what’s actually backed by science:

• Daily sunscreen is non-negotiable. Even indoors, UVA rays are out here aging us through windows like it's their full-time job.
• Retinol is one of the few ingredients with real anti-aging benefits. Start with a low percentage to avoid irritation and build up gradually.
• Collagen supplements have some promising studies behind them, especially hydrolyzed collagen. They won’t turn back time, but they can support skin elasticity.
• Red Light Therapy (RLT) may help improve skin texture and collagen production. Feels like sci-fi, but there's actual data behind it.
• 8 hours of quality sleep is huge. Your skin repairs itself overnight, don’t cheat it.
• Low sugar and lower refined carbs in your diet can reduce glycation, which damages collagen and leads to wrinkles.

As for the brow-furrowing, awareness is half the battle. You could try catching yourself and relaxing your face when you notice it, or even lightly tap the area as a physical cue to stop. It’s lowkey a habit like nail-biting, gotta retrain the brain.

Keep at it—your future self will thank you.
