Meet tretinoin +
Tretinoin is a prescription topical retinoid — a vitamin-A derivative first FDA-approved for acne and later validated for photoaging. It's one of the most researched anti-aging and acne actives in dermatology.
How to use it +
Applied at night to clean, dry skin — a pea-sized amount for the whole face. Start 2–3 nights a week and build up as your skin adjusts. Daily sunscreen is essential while using it.
What to expect +
Early dryness, peeling, and mild "purging" are common in the first few weeks. Results build gradually over 8–12 weeks. Your provider will pick a starting strength based on your skin and history.
Why tretinoin

One active, two payoffs

Tretinoin is the rare prescription that treats acne and visible aging with the same tube — which is why dermatologists have relied on it for decades.

Decades of clinical evidence

One of the most-studied topicals in dermatology, with a well-characterized profile for both acne and photoaging.

Acne and anti-aging in one

The same nightly routine can clear breakouts and soften fine lines, tone, and texture over time.

Compounded to your skin

Prescription strength selected by a licensed provider and prepared through 503A partner pharmacies.

Strength flexibility

Available in 0.025%, 0.05%, and 0.1% so your provider can dial in tolerance and results for your skin.

How it works

The science, in three steps

1

Speeds cell turnover

Tretinoin binds retinoic-acid receptors, accelerating how quickly old skin cells shed and fresh ones surface.

2

Boosts collagen

Over weeks it stimulates new collagen, which is what softens fine lines and firms skin from within.

3

Clears & smooths

Faster turnover unclogs pores and evens tone and texture — clearer skin and a smoother surface over time.

What is tretinoin?

Tretinoin is a prescription topical retinoid — a derivative of vitamin A. First approved by the FDA for acne, it later became a gold-standard active for treating fine lines, uneven tone, and sun-related aging.

It works by binding retinoic-acid receptors in the skin, speeding cell turnover and prompting new collagen. Because it's prescription-strength, tretinoin is more potent — and better studied — than the over-the-counter retinol you'll find on a shelf.

Who it's for

Is tretinoin right for you?

Tretinoin is a strong fit for adults treating acne, early aging, or texture and tone concerns. A provider confirms it's appropriate for your skin and history.

Acne & clogged pores

Persistent breakouts, blackheads, and congestion that over-the-counter products haven't resolved.

Fine lines & early aging

The beginnings of crow's feet and forehead lines, plus loss of firmness from sun exposure.

Uneven tone & texture

Dullness, rough patches, and discoloration you'd like to smooth and brighten over time.

Not for pregnancy

Tretinoin should be avoided if you're pregnant, trying to conceive, or breastfeeding — tell your provider.

How to use it & what to expect

Build up slowly

How to use tretinoin

  • WhenAt night — apply to clean, dry skin, waiting a few minutes after cleansing.
  • How muchA pea-sized amount for the whole face. More is not better and can worsen irritation.
  • FrequencyStart 2–3 nights a week, then build up gradually as your skin adjusts.
  • Every morningAlways follow with a daily broad-spectrum SPF — tretinoin increases sun sensitivity.

Available strengths — your provider selects the right starting strength:

Early on, mild "purging" — a brief uptick in breakouts as turnover speeds up — and some dryness or peeling are common. This usually settles within a few weeks as your skin builds tolerance.

Safety & side effects

⚠ Avoid if pregnant or trying to conceive

Do not use tretinoin if you are pregnant, planning to become pregnant, or breastfeeding. Tell your provider about pregnancy, all medications, and any skin conditions before starting.

  • Dryness and peeling
  • Redness or mild stinging
  • Temporary "purging" (early breakouts)
  • Increased sun sensitivity
  • Irritation if over-applied or layered with other actives

Always use daily SPF. Stop and contact your provider if you develop severe irritation, blistering, or a rash.

Questions, answered

Tretinoin FAQ

What does tretinoin do? +
Tretinoin is a prescription retinoid that speeds skin-cell turnover and stimulates collagen. That combination clears acne and clogged pores while softening fine lines, evening tone, and smoothing texture over time.
Acne and anti-aging — can it do both? +
Yes. Tretinoin is one of the few actives validated for both. The same nightly application unclogs pores to treat breakouts and, over weeks, builds collagen to reduce the look of fine lines and photoaging.
How do I use it and avoid irritation? +
Apply a pea-sized amount to clean, dry skin at night, starting just 2–3 nights a week and building up as tolerated. A gentle moisturizer helps, and daily sunscreen is essential. Going slow is the single best way to limit dryness and peeling.
What is skin purging and how long does it last? +
"Purging" is a temporary uptick in breakouts as tretinoin accelerates cell turnover and brings congestion to the surface faster. It's common in the first few weeks and usually settles within about 4–6 weeks as your skin adjusts.
Do I need sunscreen with it? +
Yes — daily, without exception. Tretinoin increases sun sensitivity, so a broad-spectrum SPF every morning protects your skin and helps preserve the results you're working toward.
Can I use it while pregnant? +
No. Tretinoin should be avoided during pregnancy, while trying to conceive, and while breastfeeding. Tell your provider if any of these apply so they can recommend a pregnancy-safe alternative.
