The verdict
The formerly prescription-only 0.1% adapalene gel, now OTC: a proven, inexpensive acne retinoid that demands patience through dryness.
Differin Gel is a 0.1% adapalene retinoid that was prescription-only until the FDA approved it for over-the-counter sale in 2016. Differin says once-daily use treats and helps prevent breakouts, blackheads and clogged pores, with best results after 12 weeks. Creators who documented 60 to 90 days of use often report clearer skin after an initial adjustment period, and dermatologists also discuss it for texture and tone. Expect dryness or a purge early on, and note it is a single-active gel rather than an elegant serum.

How it scored
Five factors, weighted for formulas. Here’s our working.
Beauty score out of 10. Brands can’t pay for placement — ever.
Adapalene is a guideline-recommended acne retinoid per the AAD guidance Differin cites, and creators documenting 60-90 days report clearer skin after an adjustment period.
A full-strength 0.1% adapalene dose in a simple gel; it lacks soothing or hydrating extras and includes methylparaben and propylene glycol.
Once-daily and fast to apply, but dryness, irritation and an early purge are common themes in long-term creator videos.
A formerly prescription retinoid sold over the counter in 15 g and 45 g sizes at drugstore pricing; price not recorded here because no readable retailer page showed it.
A staple recommendation in acne communities and dermatologist videos, with many documented before-and-after journeys.

OTC Differin gel (nightly) made a bigger difference for me than rx tret ever did. Differin did more for my closed comedones in 2 months than tret did in 2 years.
Any retinoids like Differin or Tretinoin seem to help majorly minimize sebaceous filaments...Differin is so incredibly gentle though! I can't say enough how much I love Differin.
this was my main reason for starting differin, because i had deeeeeeep closed comedones all around my mouth and chin. even while my skin is purging I can see that there are less bumps around those areas, even if there’s more surface acne.
I switched to differin for 3 months, and it seemed like my face was just getting worser. I had bad acne before but it got worse with differin overtime.
