Hi,
Value-for-money options for addressing facial pigmentation focus on sun-protection and the use of proven lightening creams. The various effective lightening creams have been discussed in depth in the relevant section. However, there is a limit to how much lightening creams may lighten your pigmentation.
For more difficult pigmentation that requires procedures to give more significant response, please discuss with your preferred aesthetic doctor your preferred options after a clear understanding of what they are, what they can achieve and what are the possible side-effects.
In general, minimal downtime procedures tend to require several treatments which will push up costs. On the other hand, more aggressive procedures that require less treatments tend to be associated with a higher risk of post-inflammatory hyperpigmentation which may bothersome albeit being temporary.
Oral lightening pills, new innovative products which have yet to establish themselves tend to offer less value compared to the above established treatments.
Hope this helps!
