Tretinoin is a powerful prescription-strength form of vitamin A (a retinoid) used primarily for treating acne and signs of aging.
๐งช What does tretinoin do?
-
Increases cell turnover – helps shed dead skin faster
-
Unclogs pores – reduces acne and blackheads
-
Boosts collagen – improves skin texture and fine lines
-
Fades hyperpigmentation – including sun spots and acne marks
๐ Common Uses:
-
Acne treatment (especially non-inflammatory and comedonal acne)
-
Anti-aging (fine lines, rough texture, sun damage)
-
Hyperpigmentation (melasma, dark spots)
-
Preventive skincare (in long-term regimens)
๐งด How to Use It:
-
Apply a pea-sized amount to clean, dry skin
-
Start with 2–3 nights per week, then increase gradually
-
Always follow with moisturizer
-
Use sunscreen daily – tretinoin increases sun sensitivity
⚠️ Side Effects (especially early on):
-
Dryness and peeling
-
Redness or irritation
-
Purging (temporary increase in breakouts)
These are often called the “retinoid uglies” and usually improve within a few weeks.
