Tips for Using Retinols
1. Start slow, use a low dose and start a couple of times per week and then start using every night if tolerated
2. Apply a pea size amount all over the face, distribute evenly
3. If ok per the product you may use on the neck area (remember that skin has less sebaceous glands so it may irritate easier)
4. If you have rosacea or other condition and cannot tolerate the retinol try some Bakuchiol
