98% Retinyl Retinoate Powder

Retinyl retinoate (RR) is a unique next-generation vitamin A derivative obtained through chemical synthesis. Its molecular structure originates from the esterification reaction between retinol and retinoic acid, "linking" the two active forms of vitamin A into a stable single compound, hence it is often called Retinol Retinoate. As a highly anticipated upgraded retinol ingredient in skincare in recent years, RR ester achieves a good balance between efficacy and tolerability. Its core competitiveness can be summarized as "dual-pathway activity + sustained-release + high stability + low irritation."

Dual Activity and Sustained-Release Mechanism of Action

Retinol retinoic acid esters do not directly and intensely irritate the skin, but rather participate in skin metabolism in a precursor form:

After entering the skin, they are gradually hydrolyzed by enzymes, releasing retinol and retinoic acid respectively;

Retinol can be further converted into retinoic acid within the skin, while also possessing certain biological activity;

Retinic acid, as the active form in the vitamin A system that directly acts on nuclear receptors, can precisely regulate keratinization, collagen production, and cell differentiation.

This structural design allows RR esters to exhibit a gradual release curve while exerting their efficacy, thereby reducing the risk of immediate irritation.

Excellent Chemical Stability

Compared to traditional retinol, retinol retinoic acid esters exhibit stronger stability at the structural level:

Multiple studies have shown that they are more resistant to changes in light, oxygen, and temperature;

They are less prone to oxidation or degradation, resulting in a longer duration of activity;

This helps reduce the reliance of formulations on light-protected packaging and complex antioxidant systems.

This characteristic not only improves the safety and efficacy of the final product but also significantly extends the product's shelf life.

Significant and Stable Bioactivity

Despite lower irritation, RR esters do not sacrifice efficacy:

Experimental data show that they excel in inhibiting c-Jun protein expression (closely related to photoaging and collagen degradation);

In promoting fibroblast activity and collagen synthesis, they are superior to retinol alone, with overall activity approaching that of retinoic acid;

They achieve the ideal state of "highly effective but not excessive" in anti-aging and repair.

Superior Skin Tolerance

Low irritation is one of the most noteworthy advantages of retinol retinoic acid esters:

Compared to retinol, which requires multiple conversion steps, and prescription-grade retinoic acid, which is more irritating;

RR esters effectively reduce vitamin A reactions such as redness, dryness, and flaking through slow release and structural stability;

More suitable for sensitive skin, consumers using retinol-based ingredients for the first time, and long-term anti-aging skincare.

Anti-aging and Firming/Lifting:

Activates collagen and elastin production, diminishes fine lines and wrinkles, and improves skin elasticity.

Repairs Photoaging Damage:

Targets signs of aging caused by UV rays, such as roughness, dullness, and fine lines, helping to restore youthful skin.

Improves Acne and Pore Condition:

Regulates sebum secretion, inhibits acne-related bacteria, reduces blackheads and whiteheads, and improves enlarged pores.

Enhances Moisturizing and Barrier Function:

Promotes the production of natural moisturizing factors such as hyaluronic acid, enhancing the stratum corneum's moisture retention and defense capabilities.

Refines Skin Texture and Promotes Renewal:

Regulates the skin's cell renewal rhythm, resulting in a smoother and more even skin surface.
