SKIN & LONGEVITY
What I Actually Use: Skin
Some of this is on my face right now. Some of it I've vetted closely enough to send a friend there.

SUN PROTECTION
The highest return thing here
Nothing else on this page undoes what UV already did. What I look for: broad spectrum, SPF 30 at minimum, and a texture I will actually wear, because the sunscreen sitting unopened in your drawer has an SPF of zero. I wear Alastin HydraTint Pro everyday.
FAVORITE SUNSCREENS
INNER GLOW
Powered by Polypodium leucotomos, niacinamide, and passion fruit extract — clinically studied ingredients that support your skin's natural defense against UV damage and photoaging from the inside out. Take 2 gummies an hour before sun exposure. Safe for kids 3 and up (1 gummy). A dermatologist-developed complement to your SPF, not a replacement for it.
SWIM ZIP
The best sunscreen is one that doesn't wash off — and that's exactly why sun protective swimwear is a game changer. UPF 50+ fabric blocks over 98% of UV rays and stays effective all day in and out of the water, no reapplication needed. For kids especially, a long-sleeve rashguard is so much easier than chasing them around with sunscreen. I wear cover-ups myself and my kid live in these brands all summer.
THE SKIN EDIT
The ones that stayed.
These are the ones that stayed. Some have decades of research behind them, like retinoids. Some are newer, and I say so in the descriptions instead of pretending the evidence is further along than it is. The two red light masks at the end are the newest thing here, and I'd put them after sunscreen and a retinoid rather than instead of either. If you're starting from nothing, start with those two.
A platelet-derived exosome serum clinically shown to reduce fine lines, boost luminosity, and support skin renewal. My go-to for skin longevity.
Targets the delicate eye area with the same powerful exosome technology. Reduces puffiness, dark circles, and fine lines over time.
Lips age too — and most lip products just moisturize, they don't actually treat. The OS-01 Lip Restore Mask goes further, using the OS-01 peptide to stimulate your skin's natural collagen, elastin, and hyaluronic acid production overnight. Apply before bed and wake up to noticeably softer, smoother lips over time.
Re-Q is powered by RLX-201, a patented longevity molecule that works by modulating mTORC1 activity in skin cells — essentially resetting exhausted cells back to a healthier, more youthful state. This is geroscience applied to skincare, and it's the kind of innovation I get excited about as a dermatologist.
This is the OTC retinoid I recommend the most, so if you've bounced off tretinoin because your face revolted, this is the one to try instead. Buy yours at Regimen Pro. Select Dr. Bonnie Koo (Skin Longevity MD) at checkout.
This is my go-to mask for a pre-event glow, post-flight hydration and post-procedure for faster recovery. This gel mask generates CO2 on the skin, inducing the Bohr effect, increasing skin oxygenation. Buy yours at Regimen Pro. Select Dr. Bonnie Koo (Skin Longevity MD) at checkout.
Most body lotions stop at hydration. OS-01 BODY lotion goes further — it's powered by the OS-01 peptide that helps skin at the cellular level. It targets senescent cells (the 'zombie cells' that accelerate aging) to support firmer, more resilient skin all over the body.
Your face is about 4% of your skin. The rest of your body often gets neglected when it comes to skin care. This is the same AlphaRet conjugate as the face version, an AHA and a retinoid together. Use nightly. Buy yours at Regimen Pro. Select Dr. Bonnie Koo (Skin Longevity MD) at checkout.
RED LIGHT MASKS
THE HAIR EDIT
Hair is rarely a one-time fix.
What works is a few things layered over time: the right topical, the right supplement, and often a prescription your dermatologist can add that no shelf product replaces. These three are the part you can start on your own. Before you do, see your dermatologist and get basic lab work (thyroid panel, iron/ferritin, vitamin D, zinc), because thinning usually has a cause worth naming first. And give it real time, 3 to 6 months.
Biotin-free, dermatologist-developed, and built around what actually drives thinning instead of the megadosed biotin that skews your lab work. Give it three months.
A lightweight, fragrance-free peptide serum you massage into the scalp daily, built around copper peptides and zinc thymulin to support the follicle environment where thinning starts.
The exosome scalp serum I use. Built on Renewosome technology out of two decades of Mayo Clinic research, and clear about what it does: the look of fuller, denser hair, not regrowth.
