Eligibility
Key inclusion criteria
* Male or female between 18 and 65 years of age inclusive, at the time of signing the informed consent.

* Moderate/Moderate to Severe acne patients, otherwise healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring for Part 3 only.
* A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GlaxoSmithKline (GSK) Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
* A female subject is eligible to participate if she is of: Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy [for this definition, "documented" refers to the outcome of the investigator's/designee's review of the subject's medical history for study eligibility, as obtained via a verbal interview with the subject or from the subject's medical records]; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 milli international units (MIU)/millilitres (mL) and estradiol <40 picograms (pg)/mL (<147 picomoles [pmol]/liter [L]) is confirmatory]. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will not be allowed.
* Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods. This criterion must be followed from the time of the first dose of study medication until after study follow-up visit.
* Alanine aminotransferase (ALT), alkaline phosphatase and bilirubin <=1.5x upper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).

Acne is allowed for Part 3.
* History of cutaneous photodisorder, such as photoallergic reaction or polymorphic light eruption. History of cold urticaria and reactions to extreme temperatures.
* History of allergy to soaps, lotions, cosmetics, tape/adhesives, petrolatum or latex or topical drugs of same class as the study medication.

Use of other topical preparations such as those containing vitamins, supplements or herbal within 2 weeks prior to dosing through treatment follow up.
* Unable to refrain from the use of topical medications from the initial dose of study medication through follow-up.

* Participation in any patch test for cumulative irritation or sensitization within 4 weeks preceding the first dose of study medication.
* Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
* The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
* Unable to refrain from the use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements (including St John's Wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study medication, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.
* Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period.
* Unwillingness or inability to follow the procedures outlined in the protocol.
* Subject is mentally or legally incapacitated.
* Unable to refrain from consumption of red wine, seville oranges, grapefruit or grapefruit juice and/or pummelos, exotic citrus fruits, grapefruit hybrids or fruit juices from 7 days prior to the first dose of study medication
