This guide is for educational purposes only and is not medical advice. GHK-Cu is not FDA approved to treat any condition, and compounded medications have not been reviewed by the FDA for safety, effectiveness, or quality. Topical retinoids should not be used during pregnancy. Talk with a licensed clinician before starting a prescription retinoid.
Prescription retinoids are the most studied anti aging creams available. A systematic review of randomized trials found topical tretinoin safe and effective for long term treatment of photoaging, and retinoids remain the first choice of many dermatologists for wrinkles and sun damage.
Not all retinoids are the same. Retinol, sold without a prescription, is about 20 times less potent than tretinoin because the skin must convert it first. We ranked 6 prescription retinoid creams by evidence, results, tolerability, and how easy they are to get.
Prescription Retinoids Compared
| Rank | Retinoid | Strength | Aging evidence | Irritation | Prescription |
|---|---|---|---|---|---|
| 1 | Tretinoin | 0.025% to 0.1% | Systematic review of trials | Moderate | Yes |
| 2 | Adapalene | 0.1% to 0.3% | Trial vs tretinoin | Low | 0.3% only |
| 3 | Tretinoin and GHK-Cu cream | Set by prescriber | Based on tretinoin | Moderate | Yes |
| 4 | Tazarotene | 0.1% | Large placebo controlled trial | High | Yes |
| 5 | Tretinoin and estriol cream | Set by prescriber | Based on tretinoin and estriol | Moderate | Yes |
| 6 | Trifarotene | 0.005% | Acne trials only | Moderate | Yes |
Full Reviews
1. Tretinoin: Gold standard
Tretinoin is the active form of vitamin A and the most studied retinoid for skin aging. It improves fine wrinkles, rough texture, and sun spots over months of nightly use, and generic versions are widely available. A review of retinoids describes tretinoin as the most potent and certainly the most widely investigated retinoid for photoaging. Dryness and peeling are common at first, so most people start every second or third night.
Not for: pregnancy or breastfeeding, or anyone with eczema or very reactive skin.
Our score breakdown: Evidence 10, Results 9, Tolerability 5, Access 8.
2. Adapalene: Gentlest retinoid
Adapalene is a newer retinoid that tends to cause less irritation. In a randomized trial, adapalene 0.3% gel showed non inferior efficacy to tretinoin 0.05% cream for photoaged skin, with a similar safety profile. The 0.1% strength, sold as Differin Gel, is available without a prescription, but the aging evidence is for the 0.3% prescription strength.
Not for: pregnancy, or anyone expecting the 0.1% strength to match prescription tretinoin.
Our score breakdown: Evidence 6, Results 6, Tolerability 8, Access 10.
3. Tretinoin and GHK-Cu Cream: Best all in one
Combination creams pair tretinoin with gentler supporting ingredients in a single product. Cashmere combines tretinoin with GHK-Cu, niacinamide, and caffeine and is prescribed after a clinician review. Its evidence comes from tretinoin itself and from separate studies of the other ingredients, since the combination has not been tested in published trials. The appeal is convenience: one cream instead of a retinoid, a serum, and an eye product.
Not for: pregnancy or breastfeeding, or anyone with a copper sensitivity.
Our score breakdown: Evidence 6, Results 8, Tolerability 6, Access 9.
4. Tazarotene: Strongest option
Tazarotene is a potent retinoid approved for photodamage. In a 24 week trial of 562 people, tazarotene 0.1% cream led to a significantly greater rate of treatment success than vehicle, and a review of randomized trials concluded it is an effective and safe treatment for photodamaged skin. It is also the most irritating retinoid, so it suits people whose skin already tolerates tretinoin.
Not for: pregnancy or anyone trying to conceive, and sensitive or dry skin.
Our score breakdown: Evidence 8, Results 9, Tolerability 3, Access 5.
5. Tretinoin and Estriol Cream: Best after menopause
After menopause, falling estrogen thins the skin. In a 6 month study, topical estriol improved elasticity and firmness and increased type III collagen. Stella+ combines estriol with tretinoin, GHK-Cu, and niacinamide in a prescription cream for postmenopausal skin, and a clinician checks whether estriol is appropriate before prescribing.
Not for: anyone advised to avoid estrogen.
Our score breakdown: Evidence 5, Results 8, Tolerability 6, Access 8.
6. Trifarotene: Acne focused
Trifarotene is the newest prescription retinoid and has published clinical trial data in facial, truncal, and hyperpigmentation associated acne. It has not been studied for wrinkles or sun damage, so it is not a first choice for anti aging.
Not for: anyone whose main goal is anti aging.
Our score breakdown: Evidence 2, Results 5, Tolerability 6, Access 5.
Is Tretinoin Better Than Retinol?
For results, yes. Tretinoin works directly, while retinol is about 20 times less potent and requires conversion to retinoic acid in the skin. Retinol is gentler and does not need a prescription, which makes it a reasonable starting point for sensitive skin. If you cannot tolerate either, the best retinol alternatives compare gentler options.
What Is Most Like Tretinoin?
Adapalene 0.3% is the closest match in clinical studies. Tazarotene is stronger, and retinaldehyde and retinol are gentler over the counter options with less evidence.
How to Start a Prescription Retinoid
- Start low: use the lowest strength two or three nights a week.
- Use a pea sized amount: apply to dry skin after cleansing, avoiding the corners of the eyes and mouth.
- Moisturize: follow with a fragrance free moisturizer to reduce dryness.
- Wear sunscreen daily: retinoids make skin more sensitive to the sun.
- Space out other actives: keep acids and copper peptide serums on separate nights, as explained in this rating of what not to mix with copper peptides.
Can You Use Prescription Retinoids During Pregnancy?
No. Topical retinoids are contraindicated in pregnancy. Stop using them if you are pregnant or trying to conceive, and talk with your doctor about safer options such as azelaic acid.
What the Evidence Does and Does Not Support
The evidence strongly supports tretinoin and tazarotene for photoaging, and adapalene 0.3% performed similarly to tretinoin in one trial. Combination creams rely on the evidence for their individual ingredients rather than trials of the finished product. Trifarotene has not been studied for aging. All prescription retinoids can irritate at first and should be avoided in pregnancy.
