Description

3bA: For a 10 mark question you should be elaborating each point you make. Consider an opponent’s argument that refutes the impact of cosmetic procedures upon psychological wellbeing by criticising the studies and surveys that exist, as they are often driven by marketing data, and contain bias or have poor methodologies.

4bA: The majority of your answer largies falls upon the category of extrinsic ageing, remember that melanin though produced by our bodies, is a defence against exogenous UV insults, what are other endogenous processes that contribute to ageing? If you are hoping to discuss free-radicals, research the accumulation of Advanced Glycation End Products (AGE) on collagen

4cA: Describe in more detail the impact of these insults to collagen and elastic fibres; consequently what are the resulting effects on the skin in terms of pigmentation, elasticity and wrinkling?

4dA: A good place to start with this question is to identify the individual who developed the scale, year of creation and what they’re used to assess. Elaborate more on the Glogau scale, which groups respond well/ less well to treatment?

4eA: Benzyl peroxide and salicylic acid are medicine and are not considered basic skin care products. I highly recommend including SPF as one of your examples and one other product. Assess their efficacy and impact upon intrinsic/extrinsic ageing processes

5dB: The two nerves of relevance branch from the frontal nerve and travels anteriorly above the levator palpebrae superioris
