Also known as: Retinaldehyde, Vitamin A Aldehyde

Best for:NormalOilyCombinationMature

A form of Vitamin A one conversion step closer to retinoic acid than retinol. More potent than retinol but gentler than tretinoin.

Treatment · PM only

Time to results

6-12 weeks for visible anti-aging effects

Benefits

More potent than retinol, antibacterial properties, anti-aging, improves texture, suitable intermediate retinoid.

How to Use

Apply at night. Start 2-3 times per week. Only one conversion step to active retinoic acid means faster results than retinol.

Can cause irritation though generally better tolerated than tretinoin. Sun sensitivity. Not as widely available as retinol.

Frequently Asked Questions

What does Retinal do for skin?

Retinal is used in skincare primarily as a retinoid ingredient. Its effects depend on concentration and formulation. Check the benefits section above for specific details.

Is Retinal safe for sensitive skin?

Retinal is generally well-tolerated, but sensitivity varies by individual. Start with a patch test if you have reactive skin, and introduce gradually into your routine.

Can I use Retinal every day?

For most skin types, daily use is appropriate at standard concentrations. If you experience any irritation, reduce frequency to every other day.

Can I use Retinal with retinol?

Use caution when combining exfoliating or active ingredients. Alternate days or use at different times of day to avoid over-irritation.

Copper PeptidesPeptide

Copper peptides, most commonly represented by the tripeptide-copper complex GHK-Cu, are small protein fragments bound to copper ions that occur naturally in human plasma, saliva, and urine. GHK-Cu plays a fundamental role in tissue remodeling by stimulating the synthesis of collagen, elastin, glycosaminoglycans, and other components of the extracellular matrix. In dermatology, copper peptides have attracted significant attention for their dual capacity to promote wound healing while simultaneously reducing the appearance of aging skin. The copper ion serves as a cofactor for lysyl oxidase, the enzyme responsible for cross-linking collagen and elastin fibers, while the GHK peptide sequence itself modulates gene expression related to tissue repair and anti-inflammatory pathways.

Pomegranate ExtractBotanical

Pomegranate extract is derived from the fruit, peel, and seeds of Punica granatum, a plant with a long history of medicinal use across multiple traditional medicine systems. The extract is exceptionally rich in ellagitannins (particularly punicalagin), ellagic acid, anthocyanins, flavonoids, and punicic acid, a conjugated linolenic acid with potent anti-inflammatory properties. In skincare, pomegranate extract provides multi-pathway antioxidant protection that addresses both lipid peroxidation and protein oxidation. Its polyphenols have been shown to inhibit UVB-induced MMP-1 expression, protecting dermal collagen from photodegradation. Punicalagin, the predominant ellagitannin in pomegranate, is one of the highest molecular weight polyphenols found in nature and is hydrolyzed in the skin to release ellagic acid, which further contributes to tyrosinase inhibition and anti-melanogenic activity.
