Unless your dermatologist prescribes more, stick to formulas with 1% retinol or less. According to Dr. Emer, "You may want 0.25% when first starting out, then increase slowly to 0.5 and then to 1.0 overtime. Switch up strengths every two to four weeks when exfoliation and irritation are tolerable."
Moderate percentages of retinol (0.03% to 0.3%) give you results faster than lower percentages of retinol. Research shows that retinol concentrations of 0.03% and greater could counteract the visible effects of environmental damage and visible thinning of skin.

Finally, 0.025% was compared to 0.1% and it was found that both produced similar improvements in photoaging.
0.3% – a relatively low but effective dose of retinol. "0.3% retinol is enough to give a good effect but also enough not to put the skin at risk or irritate the skin," continued Abi.

You may notice tretinoin starting to work within 2 to 3 weeks, but it can take 6 weeks or more to experience the full benefit. If you don't see improvement within 12 weeks, or if you have significant improvement and wonder if you should start using it less frequently, talk to your doctor.
