Retinol, Hyperpigmentation & the Benefits of including Tretinoin in Your Skincare Routine.
Start by using the retinoid creams every other day, and if your skin can tolerate it, you can increase it to everyday.
You can apply retinoid creams under the eye, but avoid the eye lid area.
Retinoid creams should always be used at night as sunlight can damage the active ingredient.
Retinoid creams make your skin more sensitive to the sun, so always make sure to wear sunscreen.
