Hydroxypinacolone retinoate (HPR) is an ester of retinoic acid and a relatively recent addition to the retinoid family, a group of vitamin A derivatives known for their multifaceted skin benefits. This highly stable retinoid provides many of the effects of retinoic acid while being gentler on the skin, making it suitable for individuals with reactive or sensitive skin. HPR operates by binding directly to retinoic acid receptors (RARs) in the skin's surface layers, bypassing the metabolic conversion steps required by precursors like retinol. This direct activation allows HPR to deliver the benefits of retinoic acid—such as cellular renewal and collagen synthesis—while reducing the potential for irritation typically associated with stronger retinoids like tretinoin. HPR has many clinical benefits; Studies demonstrate that HPR significantly reduces the appearance of fine lines and wrinkles. By promoting collagen production and enhancing cell turnover, HPR improves skin elasticity and texture, yielding a smoother, more youthful appearance. HPR has also shown to diminish hyperpigmentation and uneven skin tone, contributing to a more uniform complexion. Lastly, it is effective in addressing mild acne. Research indicates it reduces the frequency of breakouts and associated redness when used in formulations containing retinol glycospheres and papain glycospheres. Importantly, these benefits occur with minimal disruption to the skin barrier, highlighting HPR's gentler profile compared to traditional retinoic acid. Hydroxypinacolone retinoate is a versatile, stable, and less irritating retinoid that delivers anti-aging, tone-improving, and blemish-reducing benefits. Its ability to directly activate retinoic acid receptors, combined with its enhanced tolerability, makes it an attractive option for individuals seeking the benefits of retinoids without the drawbacks of irritation or sensitivity.

Cross-linked Hyaluronic Acid or Sodium Hyaluronate Crosspolymer, forms a three-dimensional mesh-like structure on the skin's surface. This unique structure acts as a breathable hydration barrier, helping to increase water retention by blocking trans epidermal water loss (TEWL). Cross-linked hyaluronic acid also has wrinkle-filling and skin-softening effect.

Medium Molecular Weight Hyaluronic Acid or Sodium Acetylated Hyaluronate (70-1,000 kDa?), occupies a unique position between high and low molecular weight hyaluronic acids, boosting skin hydration in the middle layers of the skin. It complements and enhances hydrating plumping results from famous Low and High Hyaluronic Acids, giving the skin even more suppleness and volume. It's in particularly good for those who have hollow faces due to density loss.

Low Molecular Weight Hyaluronic Acid or Sodium Hyaluronate, is a salt for derived from naturally occurring hyaluronic acid. Sodium hyaluronate has a low molecular size (<70 kDa), which allows it to penetrate the skin deeper and more effectively. Sodium hyaluronate has superior hydrating and skin-plumping benefits. Increased skin hydration also contributes to efficient desquamation, supporting the skin's natural renewal cycle.

Ultra-Low Molecular Weight? or Hydrolyzed Hyaluronic Acid? (<10 kDa), penetrates the skin the faster and the deepest compared to other forms. This provide ultra hydrating and plumping results. Additionally it can enhance collagen and elastin synthesis by stimulating fibroblast activity, resulting in firmer, denser and smoother looking skin.

Omega-3 and Omega-6 Fatty Acids are essential fatty acids that strengthen the skin barrier, improve hydration, and reduce inflammation, leading to healthier, more resilient skin. Together, these components nourish, protect, and rejuvenate the skin, resulting in a smoother, more youthful complexion.

Ectoin, alternatively spelled "ectoine," is a derivative of amino acids—organic compounds that serve as the fundamental building blocks of proteins and peptides. It functions to protect cellular structures in organisms exposed to extreme environmental conditions such as high salinity, extreme pressure, and severe temperature fluctuations. It achieves this by stabilising critical biomolecules, including enzymes, proteins, and nucleic acids. Ectoin forms a protective barrier around the skin, shielding it from environmental stressors such as ultraviolet (UVA) radiation and pollution. Furthermore, ectoin mitigates transepidermal water loss (TEWL) by reducing stress on the stratum corneum, the outermost layer of the skin, even in arid and challenging environments. Ectoin provides several scientifically backed benefits for skin health, including: - Its ability to reduce TEWL contributes to softer, smoother skin by maintaining optimal moisture levels and supporting a balanced skin microbiome. - It helps protect against UVA-induced damage, reducing hyperpigmentation and photoaging. - Ectoin alleviates skin sensitivity and stress, making it suitable for irritated or compromised skin.
