It’s a genuinely confusing thing to notice: you start tretinoin because you’ve heard it’s one of the most well-studied anti-aging ingredients available, and then a few weeks in you swear your fine lines look more obvious, not less. So — can tretinoin actually make wrinkles worse? Mostly no, but there are a few real reasons it can look that way, and they’re worth telling apart.
What the evidence actually says about retinoids and wrinkles
Tretinoin is a prescription-strength retinoid, and retinoids as a class have some of the strongest clinical evidence behind them for improving the appearance of fine lines and wrinkles over time. Harvard Health notes that retinoids work gradually, by increasing skin cell turnover and boosting collagen production — a process that gets underway over weeks and shows visible results over months, not days. The American Academy of Dermatology similarly describes retinoids as a well-supported option for improving fine lines, rough texture, and mottled pigmentation with consistent long-term use.
In other words, the expected trajectory is short-term irritation possibly followed by long-term improvement — not the reverse.
So why do lines sometimes look worse at first?
Irritation itself can look like wrinkles. Tretinoin increases cell turnover, which commonly causes dryness, flaking, redness, and a temporary “purging” period, especially in the first several weeks. According to Mayo Clinic, peeling, dryness, and stinging are common, expected side effects when starting tretinoin, particularly before your skin has adjusted. Dry, flaky, irritated skin catches light differently and can make fine lines and texture more visually obvious, even though nothing structural has changed for the worse.
Dehydration exaggerates fine lines. Fine lines around the eyes especially are sensitive to hydration. If tretinoin is drying out your skin barrier faster than your moisturizing routine can keep up, temporary dehydration lines can appear more pronounced — this is a skin-barrier issue, not permanent new wrinkling.
You may just be noticing more. Starting a new skincare routine tends to come with closer mirror inspection than usual, and normal, pre-existing expression lines (like crow’s feet from smiling or squinting) can suddenly feel “new” simply because you’re paying closer attention.
What generally helps
The AAD and most dermatology guidance point to the same practical steps: start with a lower frequency (such as two to three nights a week) and build up gradually, apply a pea-sized amount to fully dry skin, and follow with a genuinely rich, barrier-supporting moisturizer — “buffering” by applying moisturizer before tretinoin, or applying it a few minutes after, can also reduce irritation for many people. If irritation and flaking persist or worsen well beyond the typical adjustment period, that’s worth flagging to your prescribing dermatologist, since strength, frequency, or formulation may need adjusting.
The bottom line
Tretinoin making wrinkles look temporarily worse in the first weeks is usually irritation, dryness, or heightened attention — not the medication actively aging your skin. The clinical evidence supports genuine improvement in fine lines and texture with consistent, properly paced use over months. If something feels off beyond ordinary “purging” — persistent burning, unusual swelling, or irritation that isn’t settling — that’s a reason to check in with a dermatologist rather than push through on your own.
