FAQ
How do I start using 2% retinol if I'm a beginner?
Start slow. Use it once every 3 to 4 days for the first two weeks and watch for peeling or redness. If your skin tolerates it well, move to every other night, then nightly after a month. This concentration is stronger than most over the counter retinol products, so your skin needs time to build tolerance. Mix it with your moisturizer if you experience dryness.
Do I apply retinol oil before or after moisturizer?
Apply it before moisturizer. After cleansing and toning, wait for your skin to dry completely, then apply 2 to 3 drops of the retinol oil. Wait 10 to 15 minutes for it to absorb, then layer your moisturizer on top. The oil format absorbs well despite being in a squalane base.
Is 2% retinol too strong?
It's strong, but manageable if you build up slowly. Most drugstore retinol products use 0.1% to 0.5%, so 2% is significantly more potent. If you're new to retinol, consider starting with a lower concentration product first. If you're already using retinol and want to step up, this is a good value option for clinical strength results.
