Autumn and winter are often considered ideal seasons to start using retinol, as UV exposure tends to decrease during these months.
If you've been thinking, "I'd like to try retinol someday," now is the perfect time to get started.
However, many people hesitate because they worry about redness, peeling, or irritation, or feel unsure about how to use it correctly.
Knowing when to start and following a few simple tips can make retinol much easier to incorporate into your skincare routine, even if you're a beginner.
In this article, we'll explain why autumn and winter are often considered good seasons to start using retinol and share tips to help minimize redness and irritation.
Does This Sound Familiar?
- I'm interested in retinol, but I'm hesitant because I'm worried about redness and irritation.
- I'm not sure where to start, how much to use, or how often to apply it.
- I'm concerned about how to combine retinol with daytime sun protection.
- As the weather gets colder and drier, I'm becoming more concerned about my skin's firmness and smoothness.
- I've been layering multiple serums and am no longer sure which products are right for my skin.
If any of these sound familiar, let's start by looking at the basics of retinol.
What Is Retinol? Why Is Autumn and Winter a Good Time to Start?

Retinol Is a Type of Vitamin A
Retinol is a form of vitamin A.
On cosmetic ingredient lists, it may appear as "Retinol" or under names such as "Retinyl Palmitate" and "Retinyl Propionate."
These are all members of the vitamin A family and are used in skincare products to help improve the appearance of skin, leaving it looking firmer and smoother.
Redness and Dryness May Occur When You First Start Using Retinol
When first introducing retinol into your skincare routine, some people may experience redness, dryness, irritation, or peeling.
This is sometimes referred to as a "retinol reaction" or "A reaction." It is more likely to occur while your skin is still adjusting to retinol.
You may be more likely to experience irritation under the following conditions:
・Applying too much product from the beginning
・Starting with daily use right away
・Having dry skin that lacks sufficient moisture
・Over-exfoliating or rubbing your skin too much when cleansing

Autumn and Winter Are Often Considered Good Seasons to Start
When using retinol, protecting your skin from UV exposure during the day is especially important.
For this reason, autumn and winter are often considered good seasons to start using retinol, as UV levels tend to be lower. There are three main reasons:
① UV levels decrease compared to summer, making daytime sun protection easier to manage.
② You can gradually introduce retinol and give your skin time to adjust.
③ By spring, you'll have had time to establish a skincare routine that works for you.
However, autumn and winter are also seasons when the air becomes dry, making it easier for your skin to lose moisture.
The key to success is to moisturize thoroughly while introducing retinol gradually. Also, remember that UV exposure does not disappear completely during these seasons, so don't forget to apply sunscreen.
6 Essential Tips for Retinol Beginners

Tip ① Use It Only at Night
Retinol is generally recommended for use as part of your nighttime skincare routine.
In the morning, focus on a vitamin C-based serum and sunscreen.
Tip ② Start with a Small Amount
You might think that applying more product will give you better results, but the opposite is true.
Start with a small amount and gently spread a thin, even layer over your face.
Tip ③ Start with Once or Twice a Week
Rather than using retinol every day from the beginning, a common approach is to start once or twice a week and gradually increase the frequency while monitoring how your skin responds.
・Weeks 1–2: Once or twice a week
・Weeks 3–4: If your skin is adjusting well, gradually increase the frequency.
・If redness or irritation occurs: Stop using retinol temporarily and prioritize moisturizing.
※ This is a general guideline only. Please follow the product's specific directions and adjust your routine according to your skin's condition.

Tip ④ Always Pair It with Moisturizer
After applying retinol, make sure to moisturize thoroughly. Here's an example of the application order:
Cleanser → Toner → Retinol Serum → Emulsion or Moisturizer
You may also want to choose a serum that combines retinol with moisturizing ingredients such as ceramides and niacinamide. (Related article: What Are Human-Type Ceramides?)
Tip ⑤ Always Wear Sunscreen During the Day
While using retinol, make sure to maintain consistent UV protection during the day.
UV rays are still present in winter. Even when staying indoors, sunlight can enter through windows.
Tip ⑥ Avoid Combining It with Other Intensive Treatments
When you first start using retinol, try to limit skincare practices that may irritate your skin, such as physical scrubs, chemical exfoliants, and excessive cleansing. Avoiding too many potentially irritating treatments at once is key to maintaining a comfortable routine.
When Should You Stop Using Retinol?
If you experience severe redness, irritation, itching, or swelling, discontinue use. If symptoms persist, consult a dermatologist.
