Additionally, Retin-A comes in a variety of strengths such as 0.25% (the lowest), 0.5% and 1.0 % (the strongest). You'll definitely want to start using the lowest dose once or twice a week.
For the purposes of skin care, tretinoin can be thought of as a more concentrated version of retinol. This means that tretinoin is stronger than retinol. This difference in strength can help guide your decision-making when it comes to choosing a skin care product.

Retinaldehyde, also known as “retinal” — not to be confused with retinol — is the strongest of the over-the-counter retinoids. One step closer to retinoic acid on the conversion scale, it only takes one step for it to convert and become active, making it more potent than the aforementioned retinyl esters and retinol.
Retin- A (Tretinoin)
Retin-A is referenced as being 100 times stronger than retinol. It also has a more immediate effect because it is formulated as retinoic acid; unlike retinols, no conversion by the body is required. As such, many users of Retin-A experience notable improvements in as little as 4-8 weeks.
025% tretinoin cream produced similar results in overall improvement in photoaging of the face, the stronger concentration of tretinoin had “statistically significantly greater” side effects, including redness and skin peeling.
If you have mild or moderate acne, both tretinoin and adapalene are likely to produce a lasting, significant improvement if used consistently. On the whole, studies comparing tretinoin and adapalene typically find that tretinoin is slightly more effective as an acne treatment.
On average, it takes eight to 24 weeks of treatment for tretinoin to produce noticeable improvements in wrinkles and other signs of aging. One short study published in the Journal of Cosmetic Dermatology, which used a . 025 percent tretinoin cream, found a “statistically significant improvement” after just 84 days.

“Studies suggest you need to use at least 0.25% retinol or 0.025% tretinoin to be effective, so I recommend using a product that specifies the percentage.” When choosing a retinol product, Dr. Rogers says it's best to start with the lowest concentration before moving up.
Technically, retinol and Retin-A do the same thing. But retinol is much weaker than Retin-A because it first has to be converted into retinoic acid in order to be used by the skin. Retin-A is retinoic acid, so it can be used directly by the skin as soon as it's applied.
Though it's not yet understood exactly how these treatments reduce acne symptoms, testing has suggested a fairly simple account of how they differ: adapalene is less likely to cause further irritation, but tretinoin is more potent.
Tazarotene 0.1% gel (once daily) is more effective than tretinoin 0.025% gel (once daily) in reducing the numbers of papules and open comedones, and achieves a more rapid reduction in pustules in mild to moderate facial acne. Alternate-day tazarotene 0.1% gel is as effective as once-daily adapalene 0.1% gel.
Tretinoin degrades quickly when exposed to sunlight, meaning you probably won't get the best results by using it in the morning. Instead, the best time to apply tretinoin is at nighttime — usually 20 to 30 minutes after cleansing your face before you go to bed.
Retin-A Micro is a costlier, time-released version that is available only as a gel. It is less likely to cause irritation and dryness and can be applied immediately after cleansing. However, it may not be as effective as Retin-A cream for anti-aging treatments and may be better suited than creams for oilier skin types.
You may notice tretinoin starting to work within 2 to 3 weeks, but it can take 6 weeks or more to experience the full benefit. If you don't see improvement within 12 weeks, or if you have significant improvement and wonder if you should start using it less frequently, talk to your doctor.
Tretinoin is used to treat acne or other skin diseases as determined by your doctor. It works partly by keeping skin pores clear. One of the tretinoin creams is used to treat fine wrinkles, dark spots, or rough skin on the face caused by the damaging rays of the sun.

Retinaldehyde is well tolerated by patients, even at higher concentrations, unlike tretinoin, which can cause significant irritation. A concentration of 0.05% appears to be effective, is well tolerated, and allows prolonged use on sensitive areas such as the face.
The difference between them is depth and speed! Retin-A penetrates immediately and into deeper layers of your skin to repair instantly. Retinol takes a while to penetrate and repair. They are both good quality anti-aging skin care products.
