Additionally, it offers moisturizing properties that can result in a smooth, dewy finish as the formula sets. Propanediol is a considered a safe, well-tolerated ingredient, not likely to cause sensitivity. Propanediol is a versatile ingredient with additional properties that make it a favorable choice in skin care products, including its ability to boost the effectiveness of a preservative system within a formula. It can also serve as a solvent in a blend of ingredients. ⭐️Reduces dark spots and Hyperpigmentation ⭐️ Brightens your skin ⭐️ prevents wrinkles and fine lines ⭐️ increases skin elasticity ⭐️ provides cell hydration ⭐️ reduces inflammation PH level: 4.0-5.5 #skincare #cosiq #mycosiq #saferesults #joinmycosiq

Nice serum
It feels light and not greasy on my skin. It makes my face look brighter and fresher. It doesn’t irritate my skin even though I use it every day.

Good - Lightweight, but slight oily
Lightweight with a slight coconut-oil feel. But its not sticky, thats a good thing. Slight absorption issues—it doesn’t get absorbed quickly at all, so not suitable for me as a daytime product. However, it’s still better than other brands I’ve tried before.

Vitamin C serum with only 2 ingredients ❣️
This is a very good serum. Definitely a must-try. The texture is smooth, lightweight, and suitable for average skin tones. Glowing I really love it also value for money ❣️

Cosiq
Really impressed with this Cosiq Vitamin C 8% Face Serum. The formula is very minimal with only 2 ingredients, which makes it gentle and suitable even for sensitive skin. It absorbs quickly, feels lightweight, and doesn’t leave any sticky or greasy residue. After regular use, my skin looks brighter and more even-toned, with a healthy glow. No irritation or breakouts at all. Great option if you want an effective, no-nonsense vitamin C serum. Worth the buy.
