The Best Retinol Serums of 2025: Editor and Dermatologist Recommendations
Discover the top retinol serums of 2025, expertly reviewed for every skin concern—from sensitivity to stubborn wrinkles.
Retinol has long dominated the skincare world as the gold-standard ingredient for tackling wrinkles, acne, hyperpigmentation, and dullness. But, picking the right formula for your unique skin type and concerns can be overwhelming. Here, we break down the top retinol serums of 2025—each handpicked and tested by editors and dermatologists—to suit every skin goal, sensitivity, and budget. Plus, expert answers to all your burning retinol questions.
What Is Retinol and Why Should You Use It?
Retinol is a derivative of vitamin A that promotes skin cell turnover and boosts collagen production. As collagen begins to decline in your mid-20s, incorporating retinol into your nightly skincare routine can help maintain firmer, smoother, and more radiant skin over time.
- Boosts collagen production—reducing the appearance of fine lines and wrinkles
- Accelerates cell turnover—for smoother, clearer, and more even-toned skin
- Diminishes hyperpigmentation—fading spots from sun damage or breakouts
- Cleans out pores—helpful for acne-prone skin
Retinol is so effective that it’s often nicknamed “Botox in a bottle”. However, beginner users and those with sensitive skin should pay special attention to formulation types and gradually build tolerance to avoid irritation.
How and When to Use Retinol in Your Skincare Routine
To maximize retinol’s effectiveness and minimize the risk of side effects (like dryness, redness, or flaking):
- Apply at night; sunlight reduces retinol’s potency.
- Start slow: twice a week for two weeks, then increase to every other night, and eventually every night once your skin acclimates.
- Layer a moisturizer on top if extra hydration is needed.
- Always use sunscreen during the day, as retinol can make your skin extra sun-sensitive.
Tip: Most retinols are serums, but some come as creams. Apply serum right after cleansing, before heavier creams or oils. Only use one vitamin A product at a time to control your skin’s exposure.
Are Retinol Serums Suitable for Everyone?
Retinol is generally suitable for all skin types, including oily and blemish-prone skin. The main exceptions are:
- Pregnant or breastfeeding individuals
- People taking medications that interact with vitamin A
Always check with your doctor if you’re unsure.

Expert Tips for Incorporating Retinol into Your Regimen
Frequently Asked Questions (FAQs)
How does retinol work on a biological level?
Retinol converts in your skin to retinoic acid, which binds to receptors and signals your skin to accelerate cell turnover, increase collagen synthesis, and decrease pigment production—collectively resulting in renewal of the skin’s surface and support for its deeper layers.
What type of retinol is best for beginners?
Encapsulated or micro-dosed retinol (like in CeraVe and Kiehl’s) is less likely to cause redness or irritation and is ideal for those starting out. Always begin at a lower dose and gradually increase use frequency.
Is retinol good for acne-prone skin?
Yes. By speeding up cell turnover and keeping pores clear of dead cells and sebum, retinol helps minimize breakouts and post-inflammatory hyperpigmentation. Look for a gentle, oil-free base if you’re prone to blemishes.
When should I apply retinol in my evening routine?
After cleansing and before moisturizing. Let your skin dry thoroughly before applying, and always layer moisturizer afterwards to minimize dryness.
Can anyone use retinol?
Most people can use retinol, but pregnant or breastfeeding individuals and those on certain medications should avoid it. Always check with your healthcare provider if in doubt.
How do I store my retinol serum?
Keep in a cool, dark place away from sunlight and heat to maintain potency.
Are there any side effects of using retinol?
Common side effects include dryness, mild irritation, peeling, and redness, especially at the start. These usually subside as your skin adjusts. Build up usage gradually and always follow the instructions on your chosen product.
