Mikrodermabrazja czy retinol - Co lepiej działa na Twoją skórę?
Why is everyone excited about tretinoin?
Tretinoin—aka Retin-A or retinoic acid—is the gold standard in topical retinoids and prescription acne and anti-aging treatments. Tretinoin is one of the most widely researched ingredients for topical anti-aging skin treatments, and it has a few key differences from retinol:
First, one of the main differences between tretinoin and retinol is that tretinoin can get straight to work without needing to be converted to a different form first. This helps to make it more powerful—potentially up to 20 times stronger than retinol—which is one of the reasons why it has more multitasking capabilities.⁴
Similar to retinol, you can use tretinoin to help decrease signs of aging. Tretinoin works by activating specific skin receptors which help modify epithelial cell growth and differentiation.⁵ It has the ability to prevent collagen loss but also stimulate new collagen as well, helping to keep your skin firm and decrease the appearance of fine lines.⁶
While retinol and tretinoin both treat signs of aging, only tretinoin is proven to treat acne. For acne, tretinoin addresses the root of the issue by clearing out blocked pores and getting rid of dead skin cells. This process helps expel blockages and assists in preventing new lesions from forming.⁷
Curology nurse practitioner Laura Phelan, NP-C, notes, “Both tretinoin and retinol can be helpful for those looking to improve certain skin concerns, however, tretinoin works much better to help soften fine lines, lighten dark spots, and keep pores unclogged.”
One potential downside to tretinoin? It’s available by prescription only. Talk to your in-person medical provider about getting a prescription for tretinoin, or start a free consultation online through Curology—more on that later!
What is the Olay Retinol 24 Collection?
The Olay Retinol 24 is a collection of three anti-aging products whose main ingredient is retinol (1). The retinol 24 collection is one of the brands you may notice being talked about repeatedly by many beauty influencers. We decided to research this product to find out if it really is as good as they claim to be.
This collection launched in September 2019 that consisted of three products. A night moisturizer, a night serum, and a night eye cream. The group is meant to help slow down the aging process by using the benefits of retinol while hydrating your skin.
- Claimed to deliver visible improvements in fine lines and wrinkles, smoothness, brightness, firming, dark spots, and pores
- Key ingredients include niacinamide, retinol, and retinyl propionate
- Fragrance-free, dye-free formula
- Jar packaging means the retinol will deteriorate over time due to exposure to air

*All individuals are unique. Your results can and will vary.
Olay Retinol 24 Night Moisturizer comes in a jar that concerns people about the stability of the retinol. Olay did a lot of research before putting the moisturizer in a jar. They finally came up with a formula to ensure that the retinol would stay stable and potent without needing the air-tight packaging. This product is fragrance-free, dye-free, and cruelty-free.
Key Ingredients in Olay Regenerist Retinol 24 Night Moisturizer are as follows: niacinamide (2), retinol (3), and retinyl propionate (4).
What is retinol and how does it relate to retinoids?
Topical retinol is a kind of retinoid—aka a vitamin A derivative. Think of retinoids as an umbrella term, and retinol as just one type of retinoid. The main role of retinoids is to stimulate skin cell turnover and promote the production of collagen, a protein that provides structure to our skin.¹
By encouraging faster cell turnover, retinol helps replace damaged, dull skin with newer, brighter layers. And by boosting collagen production, it aids in reinforcing the skin’s structure, making it appear more youthful.²
It’s also important to note the difference in potency and availability. Retinol is classified as a cosmeceutical, meaning you can buy it without a prescription. This sets it apart from other retinoids, like tretinoin, which require a doctor's prescription. However, while retinol offers many benefits, its efficacy in skin treatment is somewhat lower compared to some of its prescription-based relatives.³
