“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.
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. Let your skin adjust and slowly increase the strengths.
Tretinoin is a medication used to treat acne and sun-damaged skin. It can't erase deep wrinkles, but it can help improve the appearance of surface wrinkles, fine lines, and darks spots.

Tretinoin Cream 0.025% or 0.05% is available in most pharmacies. As the generic equivalent of pricey Retin-A, Atralin, and Avita, Tretinoin provides the same great results at a much lower price. Because it is stronger than over-the-counter retinol products, Tretinoin Cream is available only with a prescription.
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.
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.

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.
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.

Generally, it is fine to use tretinoin every night, but you may not want to because of the initial side effects, especially when you first start. You should only use tretinoin as prescribed to avoid significant skin irritation, redness, and other side effects.
Retin-A contains the active ingredient, Tretinoin, a naturally occurring form of vitamin A. It works by speeding up the skin's metabolism to promote cellular turnover. It increases the production of elastin, collagen, and hyaluronic acid, a natural moisturizer in the skin.
Later studies evaluated Tretinoin 0.05%. While both were equally effective over a one year period, Tretinoin 0.1% was able to achieve cosmetic improvement in 6 months while 0.05% required closer to 12 months. Finally, 0.025% was compared to 0.1% and it was found that both produced similar improvements in photoaging.
Retin-A Micro is available in four strengths: 0.1%, 0.08%, 0.06% and 0.04%.
Topical creams
