Pigmented skin-care compositions
View Patent ↗A pigmented skin care composition including a dermatologically acceptable carrier and at least a first and second interference pigment. The composition according to the invention is useful in improving the appearance of the skin and in particular in reducing the appearance of skin discontinuities.
1. A skin care composition comprising:
a dermatologically acceptable carrier;
at least a first and a second interference pigment;
wherein the ratio of the first to second interference pigment is in a range between 20:80 and 80:20 by weight;
wherein the chroma of said composition over said range is less than 8.5;
wherein the redness reduction index (RRI) of said composition is less than −7.5; and
wherein the first interference pigment has a hue angle (h°) between 185°-215° and the second interference pigment has a hue angle (h°) between 80°-95°.
2. The skin care composition according to claim 1 , wherein the chroma of said composition is between 4.0 and 8.0.
3. The skin care composition according to claim 2 , wherein the composition has a redness reduction index (RRI) of less than −9.5.
4. The skin care composition according to claim 3 , wherein the composition has a redness reduction index (RRI) between −10.0 and −16.0.
5. The skin care composition according to claim 1 , wherein the total amount of interference pigments is from 0.1% to 5% by weight.
6. The skin care composition according to claim 5 , wherein the total amount of interference pigments is from 1% to 4% by weight.
7. The skin care composition according to claim 6 , wherein the composition has a healthy skin color change value (HSCCV) of less than 3.
8. The skin care composition according to claim 7 , wherein the composition has a HSCCV of between 0.5 and 2.5.
9. The skin care composition according to claim 1 , wherein the skin care composition additionally comprises at least one skin care active.
10. The skin care composition according to claim 9 , wherein the skin care active is selected from the from the group consisting of depigmentation agents and skin-lightening agents, anti-acne agents anti-aging actives, and anti-inflammatories.
11. The skin care composition according to claim 8 , wherein each of the first and second interference pigment has a particle size within the range of 2 μm and 75 μm.
12. The skin care composition according to claim 11 , wherein the composition has a multi-angle Δa* ( 0 ) value of greater than −4.0.
13. The skin care composition according to claim 12 , wherein the composition has a MADA value of between −3.5 and 0.3.
