2. How can retinol change your skin?
Well, it’s an anti-aging hero that can significantly improve the appearance of fine lines, sun damage, dark spots, and wrinkles. Not only is it said to reverse the signs of aging after daily use, but it can also act as a preventive measure too.
Studies have shown that using an over-the-counter product with 0.1% retinol (for prolonged, regular use) showed significant results in wrinkle repair, with visible improvement as early as one month.
Besides, retinol is a gentle formulation for milder acne. The benefits of retinol for acne-prone skin are to control oil production and unclog pores. So, it can decrease the pore size, prevent acne from forming and fade acne scars too.
3. What are the side effects of retinol or retinoids?
Since Retinoids help to boost the turnover rate of skin cells, so you may experience skin irritation, redness, dryness, peeling or itchiness.
The side effect of retinol will last for 2-4 weeks after your skin acclimatizes. They are more likely to happen when you just start to use or apply a higher concentration of the products. Besides, if you use too much amount of the products, it will also result in undesirable side effects
4. How to choose retinol products for your skin type?
You can choose your retinol products based on their textures: Creams are generally best for dry skin, lotions for normal to combination skin, and serums or gels for oily skin.
5. How to add retinol to your skincare routine?
The best way to introduce retinol into your skincare regimen is to start with a low concentration until you build up your tolerance bit by bit. If you experience any redness or peeling from a higher dose, then limit your retinol usage or lower the concentration.

Do’s
Apply sunscreen, always
Retinol can thin your skin and decrease its “protective capacity”. Therefore, although retinol itself is not sun-sensitizing, you should always take measures to protect your skin from sunlight, e.g. applying sunscreen daily.
Be patient and stick with it
Although there are examples that show improvements as early as a month, it can take up to 12 weeks for people to see significant changes in their skin.
Don’ts
Do not apply it daily from the beginning
Start slow and always monitor your skin’s reaction. There is a process for your skin to get adapted to retinol. In the beginning, there may be irritation and flaky skin; see how it is getting adjusted to the ingredient. Apply with a longer interval or switch to skincare products with a lower dosage if the signs of irritation persist.
Do not overuse
Use retinol only once a day and apply only a thin layer to the affected area. Remember it takes time for your skin to adjust. Even though increased dosage and frequency can speed up the process of collagen production, but it may also lead to more redness and irritation.
