HighA derivative of the most potent form of vitamin A, retinoic acid. The ingredient can be sold under name Granactive Retinoid. Note that if a skincare brand discloses the concentration of Granactive Retinoid in a product, the concentration refers to a diluted form of Hydroxypinacolone Retinoate: 1% of Granactive Retinoid corresponds to 0.1% of Hydroxypinacolone Retinoate. Hydroxypinacolone Retinoate (HPR) is a unique derivative of retinoic acid because it can directly work in the skin and does not require additional conversion steps. According to studies done by the manufacturer on models of human skin (not real people), this derivative is more effective than other cosmetic versions of retinoids (such as retinol, retinaldehyde, and retinyl palmitate), and, at the same time, causes less irritation. It has been also demonstrated to be more stable than retinol which makes formulating with easier and increases the chances that a product with it will maintain its effectiveness after opening. The packaging should still ideally be air-tight. HPR is available over the counter in the EU, UK, Asia, Australia and New Zealand, but is only with a prescription in Canada.

Clinical trials review
The number of open comedones, closed comedones and papules showed statistically significant decrease over time. Closed comedones responded faster than open comedones with significant difference seen as early as day 45. Both open and closed comedones continued to decrease in lesion count throughout the entire study period. The number of papules decreased throughout the treatment period with significant difference between baseline and days 90 and 120. Median sebumeter values showed significant decrease over time. Mild itching was experienced by 3-13% of patients from days 15 to 120, with highest percentage at day 45. Mild burning occurred in 7% of patients at day 45 but was absent at days 90 and 120. No edema was reported by any of the patients throughout the study period.

a significative improvement of all the observed characteristics has been recorded. Also the global skin photoaging evaluation, performed at the times T0 and T12 with the Glogau scale, showed a significative improvement (P<0.001).
Female patients (age 28-81 years) with photoaged skin classified with the Glogau scale n=10Product: product containing a new retinoic complex (hydroxypinacolone retinoate and retinol, associated with papain, Maca andina, Cupressus sempervirens, moisturizing complex, folic acid and vitamin E). Treatment consisted of applying the product twice daily for 8 weeks together with a topical photoprotector. No sun-exposure or artificial-UV exposure was admitted.
Clinical evaluation of the efficacy of a new retinoic-complex (Retinsphere®) product for the treatment of skin photoaging
A 41% mean reduction in the GAGS score was observed; a 40.8% mean reduction of total lesions was recorded; 15.3% of patients experienced mild to moderate local side effects (dryness, peeling, erythema, burning). No patients stopped the treatment because of these side effects.
Caucasian patients (28 males and 70 females), with an age ranging from 15 to 40 yearsn=98Product: A fixed combination of 0.1% hydroxypinacolone retinoate (synthetic esther of 9-cis-retinoic acid), 1% retinol in glycospheres and 2% papain in glycospheres in aqueous gel. Participants were treated with the product once daily for 12 weeks
Treatment of mild to moderate acne with a fixed combination of hydroxypinacolone retinoate, retinol glycospheres and papain glycospheres
Most of patients had satisfactory therapeutic response with a reduction of GAGS global score of 70%. Digital images confirmed clinical improvement (Figure 1). Micro-comedones and macro-comedones showed respectively a reduction of 38% and of 65%. Follicular biopsy proved a reduction about 60% in the density of micro and macro- comedones. No patients dropped out the study because of side effects and tolerability was very good in 90% of our sample.

Evaluation of efficacy and safety of the combinated use of two topic retinoids to treat mild / moderate acne.
In percentage terms, the reduction of the MASI at the end of the study on the side treated with the product was 74% (31%) vs. a reduction of 55% (36%) on the side that received the vehicle with SPF, with this being a significant difference (P = 0.009).
Inclusion criteria: Aged over 18 years; Absence of treatment for melasma in the last
3 months; No desire to get pregnant in the forthcoming months and use of contraceptives; No concomitant diseases; No administration of another topical or systemic product that may interfere or affect the process; No allergy to the product ingredients. 67% of patients cited a
history of sensitive skin.n=28The product included retinol glycospheres
and hydroxypinacolone retinoate, as well as N-acetylglucosamine, kojic acid, Cromabright and Natriquest,
copper and iron ions, albatin & alistin, and niacinamide. The formulation contains
10% of hydrating active ingredients and 3% anti-irritant, anti-inflammatory active ingredients. The treatment protocol included the application of the active cream with sun protection factor SPF 50
(Neoretin discrom control gel cream—IFC Pharmaceuticals) during the day and active serum (Neoretin discrom control serum booster fluid—IFC Pharmaceuticals)
at night on one side of the face vs. vehicle gelcream with
SPF 50 during the day and vehicle serum during the
night on the other side of the face; thus, the patient was
also the control group. The vehicle had the same photoprotector as the study product.

Can help neutralize free radicalsBAKUCHIOLA plant extract that is, though different in chemical structure, acts similar to retinoids. First studies show that it can help reduce fine lines and wrinkles, improve skin tone, reduce clogged pores and blemishes, and reduce inflammation. There is no conclusive evidence that bakuchiol is as effective as retinol however. The study that directly compared retinol with bakuchiol used bakuchiol applied twice daily compared to once per day for the retinol. According to this study, bakuchiol is less irritating than retinol. Bakuchiol is extracted from seeds of Babchi plant. Other parts of the plant contain coumarins that could cause allergic and irritant reactions. These compounds should be removed in the extraction process when bakuchiol is produced, but it is a good idea to be cautious and stay away from products that include the Babchi plant extracts other than purified bakuchiol to avoid irritationSULFURADAPALENEA retinoid that is effective against acne and keratosis pilaris. It can also help reduce signs of aging (fine lines, wrinkles, loss of elasticity) and can improve skin toneBETAINE SALICYLATEExfoliating acid, a "relative" of salicylic acidPOTASSIUM AZELOYL DIGLYCINATEA derivative of azelaic acid. It is obtained by reacting
the chloride of azelaic acid with two molecules of glycine (an amino acid) and potassium hydroxide. It is less studied than azelaic acid, but the available research suggests that it also can be effective in reducing skin redness, hyperpigmentation and blemishes. There are claims that it is more bio-available and more effective than azelaic acid, but no comparison study is available. Potassium azeloyl diglycinate is better soluble in water compared with azelaic acid. Because of this property, products with potassium azeloyl digclycinate can have a nicer textureCOLLOIDAL SULFURRETINYL RETINOATEA "hybrid" of retinol and retinoic acid. It is more stable than retinol and is likely to be more effective based on the early research data available. Is as irritating as retinolTretinoinBioavailable form of Vitamin A that is the most effective known topical ingredients for reducing wrinkles, improving skin firmness, treating acne, as well as hyperpigmentation. It is not available over-the counter in many countries, including US and UKRETINALOne step removed from the biologically active in skin form of vitamin A. Once converted to the retinoic acid in the skin, retinal is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. Concentrations of 0.05% and 0.1% are shown to be effective. It can, however, be irritatingRETINOLTwo steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. It can, however, be quite irritatingAZELAIC ACIDIs produced by a yeast that lives on normal human skin. It is used in medicine as a topical treatment for mild to moderate acne. It has a mild exfoliating effect. It can also help reduce hyperpigmentation, helps calm down inflammation and can help neutralize free radicals
