Uneven skin tone can be difficult to treat because most traditional methods of skin lightening can cause further irritation and further hyperpigmentation. Glycolic acid, hydroquinone and retinol should be avoided due to their irritation potential (especially since higher concentrations are needed in order to produce significant results).
M2 solves the problem by addressing two issues: the need for high potency and hyperpigmentation prevention. In its M2 Skin Refinish 20% serum, M2 combines two alpha hydroxy acids known for their non-irritating nature, mandelic acid and malic acid, in a high-potency treatment that evens skin tone, reduces breakouts and softens wrinkles. This unique combination ensures maximum results with minimal irritation.
Another product to consider is Jurlique Purely Bright Radiance Serum, which uses ingredients like hyaluronic acid to hydrate skin, turmeric extract to protect skin and calendula extract to soothe skin and reduce redness.
