Charli XCX's Differin is adapalene 0.1%, a topical retinoid for acne, and her Dalacin is clindamycin phosphate, a topical antibacterial. Differin helps prevent clogged pores by normalizing follicular-cell turnover, while Dalacin acts against acne bacteria on the skin.
Glowday reports that she named both prescription topicals while discussing polynucleotides versus fillers. For readers with acne, the pairing matters because each ingredient addresses a different part of breakouts. A retinoid targets plugs and microcomedones, and an antibiotic targets bacterial growth.

What does adapalene in Differin do?
Adapalene is the active ingredient in Differin Gel at 0.1% strength. A topical retinoid means a vitamin-A-like medicine applied to skin for acne. The official Galderma Differin site lists it for acne treatment in people 12 years and older.
The U.S. National Library of Medicine DailyMed label explains that adapalene modulates cellular differentiation, keratinization and inflammation the DailyMed adapalene label. That action normalizes turnover inside the follicle. Fewer stuck cells means fewer microcomedones, the tiny starting plugs of acne vulgaris.
What does clindamycin in Dalacin do?
Dalacin T contains clindamycin phosphate equivalent to 10 mg clindamycin per mL or gram. It comes as a solution, gel or lotion for skin use. Pfizer labeling describes clindamycin phosphate as a water-soluble ester of a semisynthetic antibiotic derived from lincomycin.
On skin, it works as a topical antibacterial acne treatment. It does not exfoliate or unclog pores like a retinoid. It reduces bacteria linked to inflamed pimples and helps calm red, tender lesions when prescribed appropriately.
Why are they used together?
The combination covers two drivers at once: clogged follicles and bacteria. That is why prescribers often pair a retinoid with a topical antibiotic rather than relying on one action alone. There is also a resistance reason to combine them.
The BMJ summary of UK NICE guidance advises topical clindamycin only in fixed combination with benzoyl peroxide or a retinoid, not alone the BMJ summary of NICE guidance. Using clindamycin by itself can encourage bacterial resistance. Readers should not copy a celebrity pairing as monotherapy or mix leftover products without medical advice.
What should you expect when starting?
Irritation is common at first, especially with a retinoid. FDA labeling warns adapalene can cause erythema, scaling, dryness, stinging and sun sensitivity FDA labeling via DailyMed. Redness means inflamed redness, and erythema is the medical term for it.
Practical habits reduce problems: Access differs by place and product. Galderma announced FDA approval of adapalene gel 0.1% for over-the-counter acne use on July 8, 2016. Dalacin remains prescription-only in many settings, so a clinician visit is usually needed to discuss strength, vehicle and combination options.
