An anti-aging skincare routine, ranked by what the evidence supports

The anti-aging routine is: sunscreen every morning, a retinoid most nights, a moisturizer that suits your skin, and — optionally — a vitamin C serum in the morning. That is the list, and the order is not arbitrary. Sunscreen and retinoids have decades of evidence behind them. Everything else in the category is supporting cast, and a great deal of it is packaging.

Roughly the majority of visible facial aging is attributed to sun exposure rather than the passage of time — the reason a forearm and a face of the same age look so different. That single fact should reorganize how you spend. If your routine has a $120 serum and no daily sunscreen, you have the hierarchy upside down, and no amount of peptide will fix it.

The morning routine

1. Gentle cleanser, or a rinse if your skin is dry. Aging skin produces less oil, so morning cleansing gets less necessary over time.
2. Vitamin C serum (optional). An antioxidant that catches what gets past your sunscreen and gradually evens tone. Genuinely useful, genuinely secondary.
3. Moisturizer. Richer than you used at twenty-five, because oil production declines steadily from your twenties onward.
4. Sunscreen. Every day, including winter, including indoors near windows. Two finger-lengths — see how much sunscreen to apply, because most people use a quarter of what the label assumes.

The evening routine

1. Cleanse properly. This is the wash that matters — it removes a day of sunscreen.
2. Retinoid, on dry skin, a pea-sized amount for the whole face. Two nights a week for the first month, three for the second, then nightly if your skin is comfortable. Rushing this is the single most common reason people quit.
3. Moisturizerover the top, generously. If the retinoid is drying, apply moisturizer first and the retinoid on top — the "sandwich" method costs a little potency and saves the whole project.

The evidence hierarchy

• 1. Sunscreen. A randomized controlled trial over more than four years found daily sunscreen use significantly reduced skin aging compared with discretionary use. Nothing else in cosmetic skincare has evidence of that quality.
• 2. Retinoids. Decades of published work on collagen synthesis, fine lines and photoaging. Tretinoin is the strongest and needs a prescription; over-the-counter retinol is a slower version of the same mechanism and works.
• 3. Antioxidants. Vitamin C has a reasonable evidence base as a supporting daytime ingredient. Real, modest, secondary to the two above.
• 4. Everything else. Peptides, growth factors, exosomes, stem-cell extracts. Some have interesting laboratory data; none has anything approaching the evidence of the top two. Buy them if you enjoy them, not because your routine needs them.

Timelines, honestly

Retinoid: texture and tone at eight to twelve weeks; fine lines at six months; the meaningful collagen effect at a year or more. Nobody sells it on a one-year timeline, which is why so many people conclude it did not work at week six. Vitamin C: brightness at eight to twelve weeks. Sunscreen: nothing visible ever, which is exactly the point — you are buying the absence of damage rather than the presence of a result.

Where the expensive tier stops helping

At around the price of a well-formulated drugstore retinol and a sunscreen you like. Above that, you are buying texture, fragrance, packaging and the pleasure of the ritual — all legitimate reasons to spend money, and none of them results. The one place we would happily pay more is sunscreen, because a formula you enjoy wearing is one you apply generously and reapply, and that genuinely outperforms a cheaper one you ration.
