Research found that just two nights of restricted sleep can lead to measurable moisture loss, reduced skin elasticity, and increased oxidative stress.

The speaker gets Intense Pulsed Light (IPL) treatments every four months and fractional non-ablative laser treatments every six months.

Non-ablative fractional lasers work by treating microscopic columns of skin while leaving surrounding tissue untouched, which speeds up the healing process.

While the speaker personally mixes retinoids and exfoliants nightly, they advise patients to use them on separate nights to avoid significant skin inflammation.

Third-generation retinoids like Adapalene are just as effective for anti-aging as the older Tretinoin but cause significantly less skin irritation.

The speaker personally uses the Korean brand "Beauty of Joseon" sunscreen or recommends "CeraVe 100% Mineral Sunscreen, SPF 50" as an alternative.

Modern chemical sunscreen ingredients like Triazorb and Bemotrizinol are large molecules that don't penetrate the skin, making them a safer alternative to older formulas.

A 2020 study showed that six common active ingredients in chemical sunscreens were absorbed into the blood at levels above FDA safety thresholds.

While both aerobic and resistance training improve skin elasticity, a study found only resistance training increases skin thickness, counteracting age-related thinning.
