re. the moisturizer for acne prone skin.....well I would consider a cleansing step very important to clean the skin as well as acting as an anti-inflammatory. Beta-hydroxy acids are good for this. Salicylic acid is the BHA I am talking about.
here's something I found posted on another site that may be of some help
ACNE
What can we do?
First, remember that acne can leave scars, keloids and changes in pigmentation, so it is important to control acne before it leads to permanent changes in the skin. Second, serious acne should be taken seriously. See you your M.D., because some genetic problems show themselves as acne, and only tests ordered by your doctor can tell you whether your acne is “normal”, i.e. caused by the hormonal turmoil of adolescence or the menstrual cycle, or whether it is a symptom of polycystic ovarian syndrome or other health problems that cause an excess in the production of male hormones by the young woman.
To control acne:
1) Keep pores open, by controlling sebum secretion using niacinamide, EGCG from green tea.
2) Normalize keratinization and prevent the exfoliated keratinocytes from sticking together. Go for white willow bark extract, which will also reduce inflammation. Other helpful actives: sulfur, retinyl acetate. Chemical peels will also help but make sure that the glycolic and other acids are not neutralized using bases like sodium hydroxide, a common ploy to impress consumers with high concentrations of acid that have been converted into useless salts.
3) Decrease inflammation: white liquorice extract. Avoid steroids, the anti-inflammatories that everybody likes because they are so fast, because they with prolonged use they will cause skin atrophy and “steroid acne”.
4) Kill acne bacteria: tea tree oil, Coleus essential oil. Propolis should also work but many of our clients do not like the smell. Avoid benzoyl peroxide, which will kill bacteria but will also age your skin and increase the probability of skin cancer.
5) For women: stabilize the hormonal balance using oral contraceptives.
