Metabolism and Functions of Amino Acids in the Skin – PubMed. (2020, January 1). PubMed. https://doi.org/10.1007/978-3-030-45328-2_11 Collagen is a protein that is naturally produced in the body and is responsible for keeping your skin firm and elastic. As you age, however, your body produces less collagen, which can lead to wrinkles and sagging skin. Vitamin C also helps fade dark spots, evens out skin tone, and increases radiance. As if that wasn’t enough, research suggests that when vitamin C is applied to the skin, it significantly reverses aging-related structural changes by influencing collagen and elastin synthesis.

Cruelty-free: REN Skincare is a cruelty-free brand, which means they do not test their products on animals. But because collagen is so ubiquitous in our body, the possible applications are much wider ranging than just skincare. When the Observer asked the clinical data analytics company Phesi to run an analysis of collagen clinical trials from 2010 onwards, just 5% were related to cosmetics. Instead, scientists around the world are more interested in its potential for some of the most serious consequences of ageing, from treating bone diseases to improving wound-healing and regenerating arthritic joints. REN Keep Young And Beautiful™ Firming And Smoothing Serum contains hexapeptide 11 from yeast fermentation to help improve skin firmness. The REN Skincare product lineup includes a wide variety of items that include facial cleansers, anti-aging products, and products for dry, acne-prone, and sensitive skin. The collection also includes body washes, all-over body cream, retinoids, toners, masks, and eye and lip care items. Since there are way too many products for us to cover in this review, we’ll focus on a few of the best selling REN Skincare products: Clean Jelly Oil Cleanser, Glow Daily AHA Tonic, and Glycolic Lactic Radiance RENewal Mask.Studies have suggested that just as with athletes, hydrolysed collagen may help regenerate the damaged joints. One trial of 120 people in 2018 found that a proportion of those taking collagen saw significant improvements in joint pain and mobility. Norwegian company Hofseth BioCare is running its own trial investigating whether various forms of collagen can help people with mild to moderate osteoarthritis. REN has been known for years for their highly effective, yet clean formulations that are sensitive skin friendly. One of their newer products includes the REN Clean Skincare Glow Daily Vitamin C Gel Cream. This moisturizing gel cream was designed to boost radiance and even out skin tone with the antioxidant power of vitamin C. This particular product contains a vitamin C ester called ascorbyl glucoside. While this ingredient does not have the same amount of research to confirm it’s efficacy that pure ascorbic acid does, this ingredient does have some notable unsides. Vitamin C esters are considerably easier to formulate with, as they are stabilized to prevent oxidation. This means that you can use the formula for longer without losing any potency. In addition to this ingredient, REN also has an extensive list of ingredients that they refuse to use in their products due to their potential irritancy. This includes ingredients like synthetic fragrance, petrochemicals, sulfate detergents, silicones, synthetic colors, animal ingredients and parabens. Price: REN Skincare products can be expensive compared to other brands, which may not be affordable for everyone. Collagen is not only important for maintaining the appearance of your skin, but it also plays a crucial role in the health of your j oints, bones, and muscles. Collagen is what gives your joints their cushioning and helps keep your bones strong. It also helps support the growth and repair of muscle tissue.

It's worth noting that bovine collagen supplements have made the news for their contribution to biodiversity issues in tropical regions (from where the ingredients are sourced). If you're keen to steer clear of these, we'd recommend opting for a marine collagen supplement instead. We've distinguished between them in our ‘key specifications' boxes to make your research that little bit more manageable. How we test

But does Ren Collagen Boost live up to its claims? In this review, we’ll take a closer look at the ingredients in these products, what customers are saying about them, and whether or not they’re worth the investment.

The only downside? Retinol can often lead to side effects like skin dryness, peeling, and irritation. While collagen is necessary for maintaining youthful-looking skin, the collagen protein is too large to absorb into the skin topically. That’s why applying skin care products that contain collagen won’t provide the anti-aging benefits you’re looking for. To help save you time and money on unsuitable products, we’ve tested a wide range of the best collagen serums available. We took into consideration how they felt on the skin, the short- and long-term results, and innovative ways they boosted collagen in the skin. We also considered each serum’s price, potency, and additional benefits. Tone: After cleansing, use a REN Skincare toner to balance your skin’s pH levels and prepare it for further treatment. Apply the toner to a cotton pad and swipe it over your face.Use of Vitamin C: Ren Skincare products often contain Vitamin C, which has been shown to have a number of benefits for the skin, including reducing hyperpigmentation and protecting against environmental stressors. A study published in the Journal of Investigative Dermatology found that Vitamin C can help to reduce hyperpigmentation. For example, a 1-star review of the Daily AHA tonic read, “ Wouldn’t recommend for sensitive dry skin. It caused break out and tiny pimples start appearing the next day.” Another displeased customer said of the day cream, “ I’ve got rosacea, and am prone to clogged pores[,] and unfortunately this seemed to do just that.”
