If there is anything you need to fully understand before going into skincare is knowing the components of your skincare ingredients, their compatibility with each other and how to mix them. When certain ingredients come in contact with each other, they lose their efficiency and become non-active. Some behave adversely and that would end up ruining your formulation. In this post, I would be discussing about some popular skincare ingredients and how to mix them. . Now, you just need to figure out whether the ingredients in all of these creams, serums, and masks work harmoniously.
Second to picking formulas for your skin formulations, it's important that all of the products  compliment one another so you can actually see results. "Mixing ingredients without proper knowledge of how these ingredients work and what other ingredients they may interact with will be not only a waste of money, but also time. It can also lead to frustration if less than expected results are seen (or if the skin becomes irritated)," says Dr. Shari Marchbein, a board-certified dermatologist in New York City.

Vitamin A-This is also referred to as retinol or tretinoin, it increases the rate at which skin cells are renewed. 
Retinol is compatible with moisturizing ingredients like hyaluronic acid and ceramides as well as SPF but not compatible with vitamin C, benzoyl peroxide, and AHA/BHA acids. Mixing it with the latter can use burns, irritations or render it ineffective.
Vitamin C- works to suppress the production of pigment within the skin but most importantly it kills free radicals that causes breakdown in collagen. In addition to skin lightening, other advantages of Vitamin C include not only antioxidant effects but some studies also demonstrate anti-inflammatory and photo-protective properties. 
Vitamin C is compatible with antioxidants and SPF but not with Retinol. It destroys the retinol and makes it ineffective.

AHA/BHA Acids-Salicylic, glycolic and lactic acids are exfoliants that can improve skin texture, tone, and treat acne. That being said, all three of these acids can dehydrate and irritate skin. 

AHA/BHA acids are compatible with moisturizing ingredients such as ceramides, hyarulonic acid and glycerin. You should never mix them with Retinol as they can cause irritation, eczema and burns.

Vitamin B3-Otherwise known as Niacinamide, this antioxidant brightens the skin and evens out discoloration. Niacinamide is compatible with (almost) every ingredient except Vitamin C. Do not use both together, rather use just one. Using both would render one ineffective which we do not want.
Now you know what to mix and what not to. If you intend making lotion and black soap, please note the ingredients that are compatible with each other and use accordingly to avoid stories that touches the heart.
