4. Do's and Don'ts
Do's
- Start low concentration, increase gradually
- Apply only at night on dry skin
- Use SPF 30+ every morning without exception
- Moisturize generously -- before or after retinol
- Wait 20 min after washing before applying
- Store in a cool, dark place (opaque packaging best)
- Be patient -- results take 8-12 weeks
- Patch test on jawline for 3 nights first
Don'ts
- Don't mix with vitamin C, AHA/BHA, or benzoyl peroxide on the same night
- Don't use if pregnant or breastfeeding
- Don't apply to wet or damp skin
- Don't wax areas where retinol is applied
- Don't start with 1% -- even if you're "tough"
- Don't use around lips, nostrils, or eye corners directly
- Don't skip sunscreen the next day, ever
- Don't give up during purging (weeks 2-6)
Ingredient Conflicts
- Vitamin C -- use in AM, retinol in PM
- AHA/BHA -- alternate nights, never same night
- Benzoyl Peroxide -- deactivates retinol on contact
- Niacinamide -- safe to combine
- Hyaluronic Acid -- safe, great buffer partner
- Peptides -- safe on alternate nights

Frequently asked questions
What strength should I start with?
The roadmap on this page starts at 0.025 percent, moves to 0.05 percent after four to six weeks, and to 0.1 percent after about three months. The 1 percent step is prescription only and belongs with a dermatologist. Starting higher does not get you there faster; it usually gets you a reaction that forces a break.
My skin is breaking out. Is it working or is it a reaction?
This page treats purging as a normal early phase that lasts four to six weeks. What changes the answer is duration and sensation: past eight weeks of breakouts, see a dermatologist, and burning or stinging is not purging — stop for three to five days and drop to a lower concentration.
Why only at night, and why the sunscreen?
Because retinol makes skin about twice as sensitive to UV. This page pairs night-only application with SPF 30 or higher every morning without exception. Applying it in the morning wastes it and raises your burn risk at the same time.
What if it stings every time?
Buffer it: moisturiser first, retinol on top, and skip two or three nights. Apply to dry skin, waiting about twenty minutes after washing, and never on broken skin. If it still stings at the lowest concentration, that is a question for a dermatologist rather than a schedule to push through.
