What Is Retin A (Tretinoin) Cream

Retin A is a vitamin A form that promotes skin renewal. It is generally available on a doctors prescription for moderate to severe photo-ageing as well acne conditions. Retinaldehyde is the closest form of Retin A without prescription. In long term studies, it provides similar results.

Active forms of Vitamin A  are known as retinoids.  Retinol, Retinal, Retin A are all retinoids whic increase cellular turnover. In the skin retinol is converted to retinal which is converted to Retin A, the most active form.  Hence, this form is prescription only. It is traditionally used to treat acne and dark spots.

Is granactive retinoid an ordinary retinol?

Granactive retinoid is a delivery system for HPR(hydroxypinacolone retinoate), a weaker form of retinol. Higher percentages and naming style confuse consumers to thinking it is a higher concentration retinol.  It is not similar to the ordinary retinol ingredient.

Why Retinaldehyde over Retinol or Retin A

Retinal (retinaldehyde) is suitable for sensitive skin due to its non irritating properties, despite being the closest derivative to retin a.  Hence, it is also popular among individuals trying a retinoid for the first time.

Retinaldehyde works for anti-ageing, photodamage and pigment issues like melasma. Stimulate RE gets converted to retinoic acid in the skin cells via conversion steps. Studies show that regular retinal use is superior in the long term to retinoic acid for collagen & hyaluronic production.

Retinoid acid directly influence the core nucleus (command centre) off the cell.   Consequently, it binds to specific receptors regulating cell function and stimulate production of collagen, elastin and new cells.

Retin A % Retinaldehyde Tips And Suggestions:

Use in low quantities in the early stages of treatment while skin builds tolerance; persist through it. RetinAl (instead of RetinOl) is less irritating to the skin, and most individuals with sensitive skin can easily tolerate it.

Strengthens the skin barrier in individuals with “sensitised skin”; the initial acute inflammatory stage subsides with consistent use.

Retinaldehyde For Sensitive Skin

“Sensitised Skin” is chronic inflammation. Inducing acute inflammation is ironically the treatment process to repair chronic inflammation of the skin. Use L-ascorbic acid (vitamin c serum) in the daytime for decreasing side effects such as redness and rarely hyper-pigmentation.

Protect the skin from prolonged direct sun exposure in the initial stages; use SPF as required.

    I have been using Stimulate RA for past two months and I am amazed at how it has transformed my skin. It has become tighter, healthier and radiant. I can clearly feel and see the difference in my skin. I highly recommend using this wonderful serum in your skin care routine.

    I have been using this for about a year now. I used it every night as a night booster. It does not irritate my skin as retinol does. However, I can see improved skin texture in the past year. My fine lines also became less visible. I will continue using it! Highly Recommend
