To optimize radiance and skin texture, it is advisable to select the correct exfoliating acid (AHAs for the surface and hydration, BHAs to purify pores) and to use a targeted retinoid duo to diminish fine lines while limiting the risk of irritation.

The concept of personalizing one's routine with specific acids is based on very solid cosmetic foundations. According to a clinical study published in the Journal of Cosmetic Dermatology (2024), the use of appropriate exfoliants significantly improves skin texture and radiance without compromising the protective barrier. AHAs even out the cutaneous surface, while BHAs effectively target congested pores and blemishes. Regarding the retinoid duo, a randomized double-blind clinical trial (RCT) published in MDPI (2026) confirms that combining different forms of vitamin A (such as retinol and retinal) can match or even surpass the efficacy of standard formulas while greatly reducing skin discomfort. The only nuance lies in the promise to completely limit irritation, as tolerance always depends on individual sensitivity, concentration, and the gradual integration of active ingredients. Overall, this advice is an excellent strategy validated by research for preserving skin youthfulness.
