A formula with retinol, like the L'Oréal Paris Revitalift Triple Power Eye Treatment, should be applied after your serums and before moisturizer due to its consistency.
And now another rule to keep in mind: Many prescription-strength retinoids suggest users wait upwards of 20 minutes post-cleansing before putting retinol on their skin and 20 more minutes before putting anything else on, according to Reddit.
Mix your retinol with your moisturizer, or apply your moisturizer first and then your retinol. Always use sunscreen the morning after you apply retinol. Your skin will be especially sensitive to sunlight, so it's important to protect it.
To use retinol before a moisturizer, wash the face and when completely dry, apply a pea-size amount of retinol. Retinol should not be used on damp skin because the skin will absorb more than required and cause irritation. Finish with a moisturizer to hydrate the skin and reduce the risk of irritation.
Goldenberg's go-to recommendation for timing between serums and moisturizers is about one minute. This wait has the same reasoning: Sixty seconds — give or take — gives each product a moment to delve into your pores.
Rouleau says the best time to use a scrub is in the morning. Overnight you've loosened up dead skin cells with your glycolic acid or retinol products, making the morning a perfect time to brush them off.
Perform the nighttime skincare routine as directed above. After applying retinol to your skin (while it's dry) allow it to sit for 10-20 minutes. Mist your face with water or a facial spray, and then apply your hyaluronic acid. (HA serums are most effective when they're applied to damp skin.)
Retinol is best applied at night since it can increase your skin's sensitivity to the sun. When you do go outside, be sure to use sunscreen to protect your face. It's worth noting that you don't need to use retinol on a daily basis for it to effectively treat your acne. Even two to three times per week might be enough.
Apply topical retinoids
Retinoids, which are topical vitamin A-based derivatives, may help reduce fine lines and wrinkles by increasing collagen production. If you use retinoids on your face, extend the treatment area to your neck and chest at night. Retinoid products are available by prescription or over the counter.
There are no set rules on how old you should be to use retinol. For anti-aging purposes, you can start preventatively in your 20s. While over-the-counter retinol can help mild acne, many people with breakouts will need a prescription.
Spread it over your face, avoiding your eyes and mouth. Afterward, you can apply any brightening products, followed by serums or night creams. “Because retinols can be drying, it's ideal to follow with an effective moisturizer to help keep skin hydrated and [the] skin's barrier protected,” Gabriel notes.
Retinol (leave to absorb for 10-20 minutes)
Retinol is also an ingredient that should be left to absorb sufficiently into the skin before following up with another product. “It is important to leave a 10-20 minute wait time before applying the next product.
Use Exfoliants Sparingly After the Adjustment Period
After two to six weeks of using tretinoin, it's usually okay to start using an exfoliant. However, it's best to use exfoliating products as sparingly as possible while using tretinoin to avoid potentially irritating your skin.
Use a retinoid sandwich method when starting to use retinoids to reduce the risk of redness/irritation (this is where you layer your moisturiser, then your retinoid and finally another light layer of moisturiser on top - remember to layer instead of mixing with your moisturizer).
