[Start slowly, only one time per week. I started Dec 5, 2024. I do not use her mask, only vitamin C serum & rollers – 0.5mm for face/neck and 0.25mm for undereyes & above/below lips. I will increase use slowly.]

How often you should derma roll your face depends on the length of the needles and your skin’s sensitivity: 

Shorter needles: You can roll every other day. 

Longer needles: You should space out treatments every three to four weeks. 

0.25 mm needles: You can use them every other day. 

0.5 mm needles: You can use them 1–3 times a week, starting with less. 

1.0 mm needles: You can use them every 10–14 days. 

1.5 mm needles: You can use them once every 3–4 weeks. 

2.0 mm needles: You should avoid using them at home. 

You should also make sure your skin is completely recovered before starting another session. Overusing a derma roller can lead to redness, irritation, and swelling. 

Here are some tips for using a derma roller: 

Limit the rolling time to a maximum of 2 minutes during each session. 

After using the derma roller, apply a serum with hyaluronic acid or niacinamide to moisturize. 

Make sure there are no bent needles. 

Start with light to no pressure. 

Go back and forth in every direction. 

You can see results after 6 to 12 weeks of regular derma rolling. 

The Timing of Exercise Affects Colorectal Cancer Risk, Study Says

Dec 13, 2025

Story at-a-glance

Early- and late-day exercise (around 8 a.m. and 6 p.m.) reduced colorectal cancer risk by 11%, with this two-peak activity pattern showing greater benefits than other exercise timing schedules

Morning exercise between 8 a.m. and 10 a.m. reduced breast cancer risk by 26%, likely because it helps lower estrogen levels during their natural daily peak around 7 a.m.

Evening exercise between 7 p.m. and 11 p.m. specifically benefited men, reducing prostate cancer risk by 25% through improved melatonin production, which helps regulate processes that protect against tumor growth

Early morning exercisers showed a 13% lower risk of developing high blood pressure over seven years, while combining morning and evening activity provided similar cardiovascular benefits

Exercise timing should align with your chronotype (whether you’re a morning or evening person), as misaligned exercise patterns may increase cardiovascular strain and reduce overall benefits
