DIY Cosmetic Formulation: Formula Analysis and Recommendations

Regarding the formula you wish to mix using a Ready use base and various ingredients including Double Hyaluronic (Hyaluron) Gel + Vitamin C 5% + Licorice Root Extract 5% + Glucosamine (N-Acetyl-D) 4% + Alpha-Arbutin 2% + Vitamin B3 5%, here is an analysis:

Face Cream Texture

Most of the ingredients you selected are water-soluble active ingredients in powder form. When mixed with a Ready use base that is a gel or light cream, adding such a relatively high total amount of powder (21% total) will significantly increase the viscosity. If the Ready use base is a clear gel, the resulting texture might be a thicker, more viscous gel or a gel-cream. If the Ready use base is already a cream, the texture might become a heavier cream.

Suitability for Combination Skin (Oily T-zone) and Skin Goals

This formula is highly suitable for combination skin with an oily T-zone and addresses your goals of whitening, brightening, and reducing wrinkles because:

• Whitening/Brightening: Ingredients like Vitamin C, Licorice Root Extract, Alpha-Arbutin, and Vitamin B3 (Niacinamide) are well-known for their properties in inhibiting melanin production, reducing dark spots, and evening out skin tone.
• Anti-aging/Wrinkles: Hyaluronic Acid provides hydration, plumping the skin and making wrinkles appear less prominent. Vitamin B3 also helps reduce wrinkles and stimulates collagen and ceramide production, making the skin stronger and more elastic. Glucosamine helps stimulate the skin's natural Hyaluronic Acid production.
• Combination/Oily T-zone: Vitamin B3 (Niacinamide) has properties that help control facial oiliness (sebum excretion), which is beneficial for those with an oily T-zone.

Points to Consider:

• The concentration of Licorice Root Extract at 5% is higher than the typical recommended usage rate (1-2%). Using a higher rate than recommended may not significantly increase efficacy and could potentially affect formula stability or texture. It is recommended to follow the supplier's suggested usage rate for optimal results and formula stability.
• The total amount of active ingredients is quite high (21%), which could impact the final texture and potentially lead to a slightly sticky feel, depending on the quality and type of the Ready use base used.

Making a Gel Eye Cream

Yes, it is possible. Using a Hyaluronic Acid Gel Base or incorporating appropriate types of Hyaluronic Acid that form a gel at suitable concentrations can help achieve a gel texture for an eye cream.

Making a Non-Sticky Body Lotion

If you want to make your own body lotion and are concerned about stickiness, you can do so by:

• Choosing the Right Lotion Base: Select a Lotion Base that has a light, non-greasy texture, or one that is specifically described as providing a comfortable, non-sticky feel.
• Selecting Water-Soluble Ingredients: Most water-soluble active ingredients are less likely to cause stickiness compared to some oil-soluble ingredients or thickeners.
• Controlling Ingredient Amounts: Adding active ingredients in excessively high amounts can alter the texture and potentially increase stickiness. It is best to use the recommended usage rates for each ingredient.

In summary, the formula you proposed for a face day cream is interesting and addresses your skin concerns well, but you should consider the concentration of some ingredients and their effect on the overall texture.
