Alpha Lipoic Acid 5% Concentrated Serum for Brightening and Signs of Aging – 30 ml

Description

PROPANEDIOL, THIOCTIC ACID (Antioxidant)

My Doctor's Diagnosis: Analysis and Target

The Ordinary's Alpha Lipoic Acid 5% concentrated serum is primarily intended for individuals concerned with signs of aging, dull complexion, and lack of radiance. This product aims to improve skin brightness, reduce fine lines, and provide powerful antioxidant action. My expert opinion is that the formulation, which focuses on a key active ingredient in high concentration, is minimalist and effective, in line with The Ordinary brand's philosophy.

Formula Analysis: Key Assets

This serum features two main active ingredients. First, alpha-lipoic acid (thioctic acid) at 5%, an antioxidant known for its ability to neutralize free radicals, protect skin cells from oxidative stress, and stimulate cell regeneration. It acts both on the surface and deep down, which sets it apart from other antioxidants. Second, propanediol, a plant-based solvent, promotes the penetration of the main active ingredient while providing a soft feel upon application. The synergy of these ingredients gives the product a noticeable effect on the skin's radiance and texture.

Tips and Application Ritual

I recommend applying this serum in the evening, on clean, dry skin, due to the potency of alpha-lipoic acid and its sensitivity to light. It is best to use it alone or before a moisturizer, avoiding combining it with other powerful active ingredients such as pure vitamin C, direct acids (AHA/BHA), or retinol in the same routine, in order to limit the risk of irritation.

My Final Verdict & Safety Opinion

The strengths of this serum lie in its high concentration of antioxidants and its short formula, which limits the risk of intolerance. Its light texture is pleasant, but I should note that the natural scent of alpha-lipoic acid may be surprising. In conclusion, this product is an excellent choice for reviving the complexion's radiance and combating skin aging, provided that the precautions for use are followed.
