Where Farmacy 1% Vitamin A Retinol Serum really shines is hydration efficacy, scoring 8.6 compared to The INKEY List 360 Acne Clearing Serum with Dioic & Salicylic Acid's 7.5. With Glycerin, Isopentyldiol, and Panthenol in its top ingredients, Farmacy 1% Vitamin A Retinol Serum delivers stronger moisture-binding capability.
Active Ingredient Strength is another area of separation. Farmacy 1% Vitamin A Retinol Serum scores 5.9 here versus 5.2 for The INKEY List 360 Acne Clearing Serum with Dioic & Salicylic Acid. That difference comes down to how each formula is built — the ingredient list tells the story.
Farmacy 1% Vitamin A Retinol Serum brings Ceramide Np, Tocopherol, and Retinol as actives, while the INKEY List 360 Acne Clearing Serum with Dioic & Salicylic Acid relies on Salicylic Acid, Zinc Pca, and Lactic Acid. Both approaches have merit, but the positioning and supporting ingredients make the difference.
At premium pricing with a score of 9.1, Farmacy 1% Vitamin A Retinol Serum delivers strong value. The INKEY List 360 Acne Clearing Serum with Dioic & Salicylic Acid sits at the mid-range level with a 8.7 score — the extra cost doesn't translate to better scores here.
