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.
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.
In clinical trials comparing adapalene and Tretinoin, both ingredients have been equally effective at fighting acne. Patients find adapalene gel less irritating, but one study found more rapid acne improvement with Tretinoin gel.
Differin 0.1% Adapalene Gel, for example, can help treat acne. Studies have found evidence to suggest adapalene is just as effective as stronger retinoids, but the skin tends to tolerate it better.
Conclusions: Tazarotene 0.1% cream can offer superior efficacy over tretinoin 0.05% emollient cream in the treatment of facial photodamage, particularly with respect to the speed of improvement.
1% tretinoin, or one unit of tretinoin per 100 units. The weakest cream contains . 005% tretinoin, or approximately 5% as much tretinoin as the strongest . 1% cream.
Absolutely not. It's a common, temporary reaction that will usually subside after about 4 weeks of use. Use of Differin Gel should not be discontinued, but be sure to always use it just once daily. Try a gentle, non-comedogenic moisturizer, like Differin Soothing Moisturizer, to help manage irritation.
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. Your skin is affected by more than what you put on it.
In conclusion, tretinoin and adapalene contributed to the wound healing process resulting in an enhancement of collagen production, angiogenesis and granulation tissue formation.
Tretinoin (aka retinoic acid) is a prescription retinoid you can get from a doctor. It's 20 times more potent than OTC retinol and achieves faster results 1. Tretinoin is also the only FDA-approved retinoid to treat photoaging (i.e., premature skin aging due to long-term sun exposure).
Background: The efficacious acne treatment adapalene gel 0.1% is significantly less irritating than tretinoin of various concentrations and formulations, according to several clinical studies conducted predominantly in Caucasian patients.
"You can use tretinoin or [over-the-counter] retinols forever."
Conclusions: Adapalene offers comparable efficacy to tretinoin, but is less irritating. It represents a good alternative for the treatment of mild to moderate acne vulgaris in Chinese patients.
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.

First, the answer is yes, retinol can make wrinkles worse, especially when you first start using it. What is happening is a drying effect, and one can get epidermal sliding from separation from the dermis.
Tretinoin gel, cream, or lotion requires a prescription because it's more powerful than retinol. Doctors prescribe tretinoin to treat skin conditions like: Acne. Psoriasis.
“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.
In addition, several over-the-counter products containing retinoids, such as retinol, are available. Because they're not as strong (and thus less irritating), they are not as effective in reducing wrinkles as tretinoin; but they do improve the appearance of photo-aged skin.
Both retinol and adapalene are retinoids, but only adapalene is FDA-approved to treat acne. Gel) regulate skin cell turnover to keep pores from clogging and to control inflammation.
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.
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.
